# env-paths
> Get paths for storing things like data, config, cache, etc
Uses the correct OS-specific paths. Most developers get this wrong.
## Install
```
$ npm install env-paths
```
## Usage
```js
import envPaths from 'env-paths';
const paths = envPaths('MyApp');
paths.data;
//=> '/home/sindresorhus/.local/share/MyApp-nodejs'
paths.config
//=> '/home/sindresorhus/.config/MyApp-nodejs'
```
## API
### paths = envPaths(name, options?)

semver(1) -- The semantic versioner for npm
===========================================
## Install
```bash
npm install semver
````
## Usage
As a node module:
```js
const semver = require('semver')
semver.valid('1.2.3') // '1.2.3'
semver.valid('a.b.c') // null
semver.clean(' =v1.2.3 ') // '1.2.3'
semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
semver.gt('1.2.3', '9.8.7') // false
semver.lt('1.2.3', '9.8.7') // true
semver.minVersion('>=1.0.0') // '1.0.0'
semver.valid(semver.coerce('v2')) // '2.0.0'
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
```
You can also just load the module for the function that you care about if
you'd like to minimize your footprint.
```js
// load the whole API at once in a single object
const semver = require('semver')
// or just load the bits you need
// all of them listed here, just pick and choose what you want
// classes
const SemVer = require('semver/classes/semver')

// working with ranges
const semverSatisfies = require('semver/functions/satisfies')
const semverMaxSatisfying = require('semver/ranges/max-satisfying')
const semverMinSatisfying = require('semver/ranges/min-satisfying')
const semverToComparators = require('semver/ranges/to-comparators')
const semverMinVersion = require('semver/ranges/min-version')
const semverValidRange = require('semver/ranges/valid')

const semverIntersects = require('semver/ranges/intersects')
const semverSimplifyRange = require('semver/ranges/simplify')
const semverRangeSubset = require('semver/ranges/subset')
```
As a command-line utility:
```
$ semver -h
A JavaScript implementation of the https://semver.org/ specification
Copyright Isaac Z. Schlueter
Usage: semver [options] <version> [<version> [...]]
Prints valid versions sorted by SemVer precedence
Options:
-r --range <range>
Print versions that match the specified range.
-i --increment [<level>]
Increment a version by the specified level. Level can
be one of: major, minor, patch, premajor, preminor,
prepatch, prerelease, or release. Default level is 'patch'.
Only one version may be specified.
--preid <identifier>
Identifier to be used to prefix premajor, preminor,
prepatch or prerelease version increments.
-l --loose
Interpret versions and ranges loosely
-n <0|1>
This is the base to be used for the prerelease identifier.
-p --include-prerelease
Always include prerelease versions in range matching
-c --coerce
Coerce a string into SemVer if possible
(does not imply --loose)
--rtl
Coerce version strings right to left
--ltr
Coerce version strings left to right (default)
Program exits successfully if any valid version satisfies
all supplied ranges, and prints all satisfying versions.
If no satisfying versions are found, then exits failure.
Versions are printed in ascending order, so supplying
multiple versions to the utility will just sort them.
```
## Versions
A "version" is described by the `v2.0.0` specification found at
<https://semver.org/>.
A leading `"="` or `"v"` character is stripped off and ignored.
Support for stripping a leading "v" is kept for compatibility with `v1.0.0` of the SemVer
specification but should not be used anymore.
## Ranges
A `version range` is a set of `comparators` that specify versions
that satisfy the range.
A `comparator` is composed of an `operator` and a `version`. The set
of primitive `operators` is:
* `<` Less than
* `<=` Less than or equal to
* `>` Greater than
* `>=` Greater than or equal to
* `=` Equal. If no operator is specified, then equality is assumed,
so this operator is optional but MAY be included.
For example, the comparator `>=1.2.7` would match the versions
`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and
would match the versions `2.0.0` and `3.1.0`, but not the versions
`1.0.1` or `1.1.0`.
Comparators can be joined by whitespace to form a `comparator set`,
which is satisfied by the **intersection** of all of the comparators
it includes.
A range is composed of one or more comparator sets, joined by `||`. A
version matches a range if and only if every comparator in at least
one of the `||`-separated comparator sets is satisfied by the version.
For example, the range `>=1.2.7 <1.3.0` would match the versions
`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
or `1.1.0`.
The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
### Prerelease Tags
If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
it will only be allowed to satisfy comparator sets if at least one
comparator with the same `[major, minor, patch]` tuple also has a
prerelease tag.
For example, the range `>1.2.3-alpha.3` would be allowed to match the
version `1.2.3-alpha.7`, but it would *not* be satisfied by
`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
than" `1.2.3-alpha.3` according to the SemVer sort rules. The version
range only accepts prerelease tags on the `1.2.3` version.
Version `3.4.5` *would* satisfy the range because it does not have a
prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
The purpose of this behavior is twofold. First, prerelease versions
frequently are updated very quickly, and contain many breaking changes
that are (by the author's design) not yet fit for public consumption.
Therefore, by default, they are excluded from range-matching
semantics.
Second, a user who has opted into using a prerelease version has
indicated the intent to use *that specific* set of
alpha/beta/rc versions. By including a prerelease tag in the range,
the user is indicating that they are aware of the risk. However, it
is still not appropriate to assume that they have opted into taking a
similar risk on the *next* set of prerelease versions.
Note that this behavior can be suppressed (treating all prerelease
versions as if they were normal versions, for range-matching)
by setting the `includePrerelease` flag on the options
object to any
[functions](https://github.com/npm/node-semver#functions) that do
range matching.
#### Prerelease Identifiers
The method `.inc` takes an additional `identifier` string argument that
will append the value of the string as a prerelease identifier:
```javascript
semver.inc('1.2.3', 'prerelease', 'beta')
// '1.2.4-beta.0'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta
1.2.4-beta.0
```
Which then can be used to increment further:
```bash
$ semver 1.2.4-beta.0 -i prerelease
1.2.4-beta.1
```
To get out of the prerelease phase, use the `release` option:
```bash
$ semver 1.2.4-beta.1 -i release
1.2.4
```
#### Prerelease Identifier Base
The method `.inc` takes an optional parameter 'identifierBase' string
that will let you let your prerelease number as zero-based or one-based.
Set to `false` to omit the prerelease number altogether.
If you do not specify this parameter, it will default to zero-based.
```javascript
semver.inc('1.2.3', 'prerelease', 'beta', '1')
// '1.2.4-beta.1'
```
```javascript
semver.inc('1.2.3', 'prerelease', 'beta', false)
// '1.2.4-beta'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta -n 1
1.2.4-beta.1
```
```bash
$ semver 1.2.3 -i prerelease --preid beta -n false
1.2.4-beta
```
### Advanced Range Syntax
Advanced range syntax desugars to primitive comparators in
deterministic ways.
Advanced ranges may be combined in the same way as primitive
comparators using white space or `||`.
#### Hyphen Ranges `X.Y.Z - A.B.C`
Specifies an inclusive set.
* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
If a partial version is provided as the first version in the inclusive
range, then the missing pieces are replaced with zeroes.
* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
If a partial version is provided as the second version in the
inclusive range, then all versions that start with the supplied parts
of the tuple are accepted, but nothing that would be greater than the
provided tuple parts.
* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
Any of `X`, `x`, or `*` may be used to "stand in" for one of the
numeric values in the `[major, minor, patch]` tuple.
* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless
`includePrerelease` is specified, in which case any version at all
satisfies)
* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions)
A partial version range is treated as an X-Range, so the special
character is in fact optional.
* `""` (empty string) := `*` := `>=0.0.0`
* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
#### Tilde Ranges `~1.2.3` `~1.2` `~1`
Allows patch-level changes if a minor version is specified on the
comparator. Allows minor-level changes if not.
* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0-0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
Allows changes that do not modify the left-most non-zero element in the
`[major, minor, patch]` tuple. In other words, this allows patch and
minor updates for versions `1.0.0` and above, patch updates for
versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
Many authors treat a `0.x` version as if the `x` were the major
"breaking-change" indicator.
Caret ranges are ideal when an author may make breaking changes
between `0.2.4` and `0.3.0` releases, which is a common practice.
However, it presumes that there will *not* be breaking changes between
`0.2.4` and `0.2.5`. It allows for changes that are presumed to be
additive (but non-breaking), according to commonly observed practices.
* `^1.2.3` := `>=1.2.3 <2.0.0-0`
* `^0.2.3` := `>=0.2.3 <0.3.0-0`
* `^0.0.3` := `>=0.0.3 <0.0.4-0`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4-0` Note that prereleases in the
`0.0.3` version *only* will be allowed, if they are greater than or
equal to `beta`. So, `0.0.3-pr.2` would be allowed.
When parsing caret ranges, a missing `patch` value desugars to the
number `0`, but will allow flexibility within that value, even if the
major and minor versions are both `0`.
* `^1.2.x` := `>=1.2.0 <2.0.0-0`
* `^0.0.x` := `>=0.0.0 <0.1.0-0`
* `^0.0` := `>=0.0.0 <0.1.0-0`
A missing `minor` and `patch` values will desugar to zero, but also
allow flexibility within those values, even if the major version is
zero.
* `^1.x` := `>=1.0.0 <2.0.0-0`
* `^0.x` := `>=0.0.0 <1.0.0-0`
### Range Grammar
Putting all this together, here is a Backus-Naur grammar for ranges,
for the benefit of parser authors:
```bnf
range-set ::= range ( logical-or range ) *
logical-or ::= ( ' ' ) * '||' ( ' ' ) *
range ::= hyphen | simple ( ' ' simple ) * | ''
hyphen ::= partial ' - ' partial
simple ::= primitive | partial | tilde | caret
primitive ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
partial ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
xr ::= 'x' | 'X' | '*' | nr
nr ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
tilde ::= '~' partial
caret ::= '^' partial
qualifier ::= ( '-' pre )? ( '+' build )?
pre ::= parts
build ::= parts
parts ::= part ( '.' part ) *
part ::= nr | [-0-9A-Za-z]+
```
## Functions
All methods and classes take a final `options` object argument. All
options in this object are `false` by default. The options supported
are:
- `loose`: Be more forgiving about not-quite-valid semver strings.
(Any resulting output will always be 100% strict compliant, of
course.) For backwards compatibility reasons, if the `options`
argument is a boolean value instead of an object, it is interpreted
to be the `loose` param.
- `includePrerelease`: Set to suppress the [default
behavior](https://github.com/npm/node-semver#prerelease-tags) of
excluding prerelease tagged versions from ranges unless they are
explicitly opted into.
Strict-mode Comparators and Ranges will be strict about the SemVer
strings that they parse.
* `valid(v)`: Return the parsed version, or null if it's not valid.
* `inc(v, releaseType, options, identifier, identifierBase)`:
Return the version incremented by the release
type (`major`, `premajor`, `minor`, `preminor`, `patch`,
`prepatch`, `prerelease`, or `release`), or null if it's not valid
* `premajor` in one call will bump the version up to the next major
version and down to a prerelease of that major version.
`preminor`, and `prepatch` work the same way.
* If called from a non-prerelease version, `prerelease` will work the
same as `prepatch`. It increments the patch version and then makes a
prerelease. If the input version is already a prerelease it simply
increments it.
* `release` will remove any prerelease part of the version.
* `identifier` can be used to prefix `premajor`, `preminor`,
`prepatch`, or `prerelease` version increments. `identifierBase`
is the base to be used for the `prerelease` identifier.
* `prerelease(v)`: Returns an array of prerelease components, or null
if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
* `major(v)`: Return the major version number.
* `minor(v)`: Return the minor version number.
* `patch(v)`: Return the patch version number.
* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
or comparators intersect.
* `parse(v)`: Attempt to parse a string as a semantic version, returning either
a `SemVer` object or `null`.
### Comparison
* `gt(v1, v2)`: `v1 > v2`
* `gte(v1, v2)`: `v1 >= v2`
* `lt(v1, v2)`: `v1 < v2`
* `lte(v1, v2)`: `v1 <= v2`
* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
even if they're not the same string. You already know how to
compare strings.
* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
the corresponding function above. `"==="` and `"!=="` do simple
string comparison, but are included for completeness. Throws if an
invalid comparison string is provided.
* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
`v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions
in descending order when passed to `Array.sort()`.
* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
are equal. Sorts in ascending order if passed to `Array.sort()`.
* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`.
* `diff(v1, v2)`: Returns the difference between two versions by the release type
(`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
or null if the versions are the same.
### Sorting
* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild`
function.
* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on
the `compareBuild` function in descending order.
### Comparators
* `intersects(comparator)`: Return true if the comparators intersect
### Ranges
* `validRange(range)`: Return the valid range or null if it's not valid.
* `satisfies(version, range)`: Return true if the version satisfies the
range.
* `maxSatisfying(versions, range)`: Return the highest version in the list
that satisfies the range, or `null` if none of them do.
* `minSatisfying(versions, range)`: Return the lowest version in the list
that satisfies the range, or `null` if none of them do.
* `minVersion(range)`: Return the lowest version that can match
the given range.
* `gtr(version, range)`: Return `true` if the version is greater than all the
versions possible in the range.
* `ltr(version, range)`: Return `true` if the version is less than all the
versions possible in the range.
* `outside(version, range, hilo)`: Return true if the version is outside
the bounds of the range in either the high or low direction. The
`hilo` argument must be either the string `'>'` or `'<'`. (This is
the function called by `gtr` and `ltr`.)
* `intersects(range)`: Return true if any of the range comparators intersect.
* `simplifyRange(versions, range)`: Return a "simplified" range that
matches the same items in the `versions` list as the range specified. Note
that it does *not* guarantee that it would match the same versions in all
cases, only for the set of versions provided. This is useful when
generating ranges by joining together multiple versions with `||`
programmatically, to provide the user with something a bit more
ergonomic. If the provided range is shorter in string-length than the
generated range, then that is returned.
* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
entirely contained by the `superRange` range.
Note that, since ranges may be non-contiguous, a version might not be
greater than a range, less than a range, *or* satisfy a range! For
example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
until `2.0.0`, so version `1.2.10` would not be greater than the
range (because `2.0.1` satisfies, which is higher), nor less than the
range (since `1.2.8` satisfies, which is lower), and it also does not
satisfy the range.
If you want to know if a version satisfies or does not satisfy a
range, use the `satisfies(version, range)` function.
### Coercion
* `coerce(version, options)`: Coerces a string to semver if possible
This aims to provide a very forgiving translation of a non-semver string to
semver. It looks for the first digit in a string and consumes all
remaining characters which satisfy at least a partial semver (e.g., `1`,
`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer
versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All
surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
`3.4.0`). Only text which lacks digits will fail coercion (`version one`
is not valid). The maximum length for any semver component considered for
coercion is 16 characters; longer components will be ignored
(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any
semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
components are invalid (`9999999999999999.4.7.4` is likely invalid).
If the `options.rtl` flag is set, then `coerce` will return the right-most
coercible tuple that does not share an ending index with a longer coercible
tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
any other overlapping SemVer tuple.
If the `options.includePrerelease` flag is set, then the `coerce` result will contain
prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2`
will preserve prerelease `rc.1` and build `rev.2` in the result.
### Clean
* `clean(version)`: Clean a string to be a valid semver if possible
This will return a cleaned and trimmed semver version. If the provided
version is not valid a null will be returned. This does not work for
ranges.
ex.
* `s.clean(' = v 2.1.5foo')`: `null`
* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean(' = v 2.1.5-foo')`: `null`
* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean('=v2.1.5')`: `'2.1.5'`
* `s.clean(' =v2.1.5')`: `'2.1.5'`
* `s.clean(' 2.1.5 ')`: `'2.1.5'`
* `s.clean('~1.0.0')`: `null`
## Constants
As a convenience, helper constants are exported to provide information about what `node-semver` supports:
### `RELEASE_TYPES`
- major
- premajor
- minor
- preminor
- patch
- prepatch
- prerelease
```
const semver = require('semver');
if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
console.log('This is a valid release type!');
} else {
console.warn('This is NOT a valid release type!');
}
```
### `SEMVER_SPEC_VERSION`
2.0.0
```
const semver = require('semver');
console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
```
## Exported Modules

TODO: Make sure that all of these items are documented (classes aren't,
eg), and then pull the module name into the documentation for that specific
thing.
-->

A JavaScript implementation of the https://semver.org/ specification
Copyright Isaac Z. Schlueter
Usage: semver [options] <version> [<version> [...]]
Prints valid versions sorted by SemVer precedence
Options:
-r --range <range>
Print versions that match the specified range.
-i --increment [<level>]
Increment a version by the specified level. Level can
be one of: major, minor, patch, premajor, preminor,
prepatch, prerelease, or release. Default level is 'patch'.
Only one version may be specified.
--preid <identifier>
Identifier to be used to prefix premajor, preminor,
prepatch or prerelease version increments.
-l --loose
Interpret versions and ranges loosely
-p --include-prerelease
Always include prerelease versions in range matching
-c --coerce
Coerce a string into SemVer if possible
(does not imply --loose)
--rtl
Coerce version strings right to left
--ltr
Coerce version strings left to right (default)
-n <base>
Base number to be used for the prerelease identifier.
Can be either 0 or 1, or false to omit the number altogether.
Defaults to 0.
Program exits successfully if any valid version satisfies
all supplied ranges, and prints all satisfying versions.
If no satisfying versions are found, then exits failure.
Versions are printed in ascending order, so supplying
multiple versions to the utility will just sort them.`)

# conf
> Simple config handling for your app or module
All you have to care about is what to persist. This module will handle all the dull details like where and how.
**It does not support multiple processes writing to the same store.**\
I initially made this tool to let command-line tools persist some data.
*If you need this for Electron, check out [`electron-store`](https://github.com/sindresorhus/electron-store) instead.*
## Install
```sh
npm install conf
```
## Usage
```js
import Conf from 'conf';
const config = new Conf({projectName: 'foo'});
config.set('unicorn', '🦄');
console.log(config.get('unicorn'));
//=> '🦄'
// Use dot-notation to access nested properties
config.set('foo.bar', true);
console.log(config.get('foo'));
//=> {bar: true}
config.delete('unicorn');
console.log(config.get('unicorn'));
//=> undefined
```
Or [create a subclass](https://github.com/sindresorhus/electron-store/blob/main/index.js).
## API
Changes are written to disk atomically, so if the process crashes during a write, it will not corrupt the existing config.
### Conf(options?)
Returns a new instance.
### options
Type: `object`
#### defaults
Type: `object`
Default values for the config items.
**Note:** The values in `defaults` will overwrite the `default` key in the `schema` option.
#### schema
Type: `object`
[JSON Schema](https://json-schema.org) to validate your config data.
This will be the [`properties`](https://json-schema.org/understanding-json-schema/reference/object.html#properties) object of the JSON schema. That is, define `schema` as an object where each key is the name of your data's property and each value is a JSON schema used to validate that property.
Example:
```js
import Conf from 'conf';
const schema = {
foo: {
type: 'number',
maximum: 100,
minimum: 1,
default: 50
},
bar: {
type: 'string',
format: 'url'
}
};
const config = new Conf({
projectName: 'foo',
schema
});
console.log(config.get('foo'));
//=> 50
config.set('foo', '1');
// [Error: Config schema violation: `foo` should be number]
```
**Note:** The `default` value will be overwritten by the `defaults` option if set.
#### rootSchema
Type: `object`
Top-level properties for the schema, excluding `properties` field.
Example:
```js
import Conf from 'conf';
const store = new Conf({
projectName: 'foo',
schema: { /* … */ },
rootSchema: {
additionalProperties: false
}
});
```
#### ajvOptions
Type: `object`
[Options passed to AJV](https://ajv.js.org/options.html).
Under the hood, the JSON Schema validator [ajv](https://ajv.js.org/json-schema.html) is used to validate your config. We use [JSON Schema draft-2020-12](https://json-schema.org/draft/2020-12/release-notes) and support all validation keywords and formats.
**Note:** By default, `allErrors` and `useDefaults` are both set to `true`, but can be overridden.
Example:
```js
import Conf from 'conf';
const store = new Conf({
projectName: 'foo',
schema: { /* … */ },
rootSchema: {
additionalProperties: false
},
ajvOptions: {
removeAdditional: true
}
});
```
#### migrations
Type: `object`
**Important: I cannot provide support for this feature. It has some known bugs. I have no plans to work on it, but pull requests are welcome.**
You can use migrations to perform operations to the store whenever a **project version** is upgraded.
The `migrations` object should consist of a key-value pair of `'version': handler`. The `version` can also be a [semver range](https://github.com/npm/node-semver#ranges).
Example:
```js
import Conf from 'conf';
const store = new Conf({
projectName: 'foo',
projectVersion: …,
migrations: {
'0.0.1': store => {
store.set('debugPhase', true);
},
'1.0.0': store => {
store.delete('debugPhase');
store.set('phase', '1.0.0');
},
'1.0.2': store => {
store.set('phase', '1.0.2');
},
'>=2.0.0': store => {
store.set('phase', '>=2.0.0');
}
}
});
```
> Note: The version the migrations use refers to the **project version** by default. If you want to change this behavior, specify the [`projectVersion`](#projectVersion) option.
#### beforeEachMigration
Type: `Function`\
Default: `undefined`
The given callback function will be called before each migration step.
The function receives the store as the first argument and a context object as the second argument with the following properties:
- `fromVersion` - The version the migration step is being migrated from.
- `toVersion` - The version the migration step is being migrated to.
- `finalVersion` - The final version after all the migrations are applied.
- `versions` - All the versions with a migration step.
This can be useful for logging purposes, preparing migration data, etc.
Example:
```js
import Conf from 'conf';
console.log = someLogger.log;
const mainConfig = new Conf({
projectName: 'foo1',
beforeEachMigration: (store, context) => {
console.log(`[main-config] migrate from ${context.fromVersion} → ${context.toVersion}`);
},
migrations: {
'0.4.0': store => {
store.set('debugPhase', true);
},
}
});
const secondConfig = new Conf({
projectName: 'foo2',
beforeEachMigration: (store, context) => {
console.log(`[second-config] migrate from ${context.fromVersion} → ${context.toVersion}`);
},
migrations: {
'1.0.1': store => {
store.set('debugPhase', true);
},
}
});
```
#### configName
Type: `string`\
Default: `'config'`
Name of the config file (without extension).
Useful if you need multiple config files for your app or module. For example, different config files between two major versions.
#### projectName
Type: `string`
**Required unless you specify the `cwd` option.**
You can fetch the `name` field from package.json.
#### projectVersion
Type: `string`
**Required if you specify the `migration` option.**
You can fetch the `version` field from package.json.
#### cwd
Type: `string`\
Default: System default [user config directory](https://github.com/sindresorhus/env-paths#pathsconfig)
**You most likely don't need this. Please don't use it unless you really have to. By default, it will pick the optimal location by adhering to system conventions. You are very likely to get this wrong and annoy users.**
Overrides `projectName`.
The only use-case I can think of is having the config located in the app directory or on some external storage.
#### encryptionKey
Type: `string | Uint8Array | TypedArray | DataView`\
Default: `undefined`
Note that this is **not intended for security purposes**, since the encryption key would be easily found inside a plain-text Node.js app.
Its main use is for obscurity. If a user looks through the config directory and finds the config file, since it's just a JSON file, they may be tempted to modify it. By providing an encryption key, the file will be obfuscated, which should hopefully deter any users from doing so.
When specified, the store will be encrypted using the [`aes-256-cbc`](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation) encryption algorithm.
#### fileExtension
Type: `string`\
Default: `'json'`
Extension of the config file.
You would usually not need this, but could be useful if you want to interact with a file with a custom file extension that can be associated with your app. These might be simple save/export/preference files that are intended to be shareable or saved outside of the app.
#### clearInvalidConfig
Type: `boolean`\
Default: `false`
The config is cleared if reading the config file causes a `SyntaxError`. This is a good behavior for unimportant data, as the config file is not intended to be hand-edited, so it usually means the config is corrupt and there's nothing the user can do about it anyway. However, if you let the user edit the config file directly, mistakes might happen and it could be more useful to throw an error when the config is invalid instead of clearing.
#### serialize
Type: `Function`\
Default: `value => JSON.stringify(value, null, '\t')`
Function to serialize the config object to a UTF-8 string when writing the config file.
You would usually not need this, but it could be useful if you want to use a format other than JSON.
#### deserialize
Type: `Function`\
Default: `JSON.parse`
Function to deserialize the config object from a UTF-8 string when reading the config file.
You would usually not need this, but it could be useful if you want to use a format other than JSON.
#### projectSuffix
Type: `string`\
Default: `'nodejs'`
**You most likely don't need this. Please don't use it unless you really have to.**
Suffix appended to `projectName` during config file creation to avoid name conflicts with native apps.
You can pass an empty string to remove the suffix.
For example, on macOS, the config file will be stored in the `~/Library/Preferences/foo-nodejs` directory, where `foo` is the `projectName`.
#### accessPropertiesByDotNotation
Type: `boolean`\
Default: `true`
Accessing nested properties by dot notation. For example:
```js
import Conf from 'conf';
const config = new Conf({projectName: 'foo'});
config.set({
foo: {
bar: {
foobar: '🦄'
}
}
});
console.log(config.get('foo.bar.foobar'));
//=> '🦄'
```
Alternatively, you can set this option to `false` so the whole string would be treated as one key.
```js
import Conf from 'conf';
const config = new Conf({
projectName: 'foo',
accessPropertiesByDotNotation: false
});
config.set({
`foo.bar.foobar`: '🦄'
});
console.log(config.get('foo.bar.foobar'));
//=> '🦄'
```
#### watch
type: `boolean`\
Default: `false`
Watch for any changes in the config file and call the callback for `onDidChange` or `onDidAnyChange` if set. This is useful if there are multiple processes changing the same config file.
#### configFileMode
Type: `number`\
Default: `0o666`
The [mode](https://en.wikipedia.org/wiki/File-system_permissions#Numeric_notation) that will be used for the config file.
You would usually not need this, but it could be useful if you want to restrict the permissions of the config file. Setting a permission such as `0o600` would result in a config file that can only be accessed by the user running the program.
Note that setting restrictive permissions can cause problems if different users need to read the file. A common problem is a user running your tool with and without `sudo` and then not being able to access the config the second time.
### Instance
You can use [dot-notation](https://github.com/sindresorhus/dot-prop) in a `key` to access nested properties.
The instance is [`iterable`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Iteration_protocols) so you can use it directly in a [`for…of`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Statements/for...of) loop.
#### .set(key, value)
Set an item.
The `value` must be JSON serializable. Trying to set the type `undefined`, `function`, or `symbol` will result in a TypeError.
#### .set(object)
Set multiple items at once.
#### .get(key, defaultValue?)
Get an item or `defaultValue` if the item does not exist.
#### .reset(...keys)
Reset items to their default values, as defined by the `defaults` or `schema` option.
Use `.clear()` to reset all items.
#### .has(key)
Check if an item exists.
#### .delete(key)
Delete an item.
#### .clear()
Delete all items.
This resets known items to their default values, if defined by the `defaults` or `schema` option.
#### .onDidChange(key, callback)
`callback`: `(newValue, oldValue) => {}`
Watches the given `key`, calling `callback` on any changes.
When a key is first set `oldValue` will be `undefined`, and when a key is deleted `newValue` will be `undefined`.
Returns a function which you can use to unsubscribe:
```js
const unsubscribe = conf.onDidChange(key, callback);
unsubscribe();
```
#### .onDidAnyChange(callback)
`callback`: `(newValue, oldValue) => {}`
Watches the whole config object, calling `callback` on any changes.
`oldValue` and `newValue` will be the config object before and after the change, respectively. You must compare `oldValue` to `newValue` to find out what changed.
Returns a function which you can use to unsubscribe:
```js
const unsubscribe = conf.onDidAnyChange(callback);
unsubscribe();
```
#### .size
Get the item count.
#### .store
Get all the config as an object or replace the current config with an object:
```js
conf.store = {
hello: 'world'
};
```
#### .path
Get the path to the config file.
## FAQ
### How is this different from [`configstore`](https://github.com/yeoman/configstore)?
I'm also the author of `configstore`. While it's pretty good, I did make some mistakes early on that are hard to change at this point. This module is the result of everything I learned from making `configstore`. Mainly where the config is stored. In `configstore`, the config is stored in `~/.config` (which is mainly a Linux convention) on all systems, while `conf` stores config in the system default [user config directory](https://github.com/sindresorhus/env-paths#pathsconfig). The `~/.config` directory, it turns out, often have an incorrect permission on macOS and Windows, which has caused a lot of grief for users.
### Can I use YAML or another serialization format?
The `serialize` and `deserialize` options can be used to customize the format of the config file, as long as the representation is compatible with `utf8` encoding.
Example using YAML:
```js
import Conf from 'conf';
import yaml from 'js-yaml';
const config = new Conf({
projectName: 'foo',
fileExtension: 'yaml',
serialize: yaml.safeDump,
deserialize: yaml.safeLoad
});
```
