# `find-config`
[![NPM version][npm-img]][npm-url] [![Downloads][downloads-img]][npm-url] [![Build Status][travis-img]][travis-url] [![Coverage Status][coveralls-img]][coveralls-url] [![Chat][gitter-img]][gitter-url] [![Tip][amazon-img]][amazon-url]
Finds the first matching config file, if any, in the current directory, nearest ancestor, or user's home directory. Supports finding files within a subdirectory of an ancestor directory. Configurable with defaults set to support the [XDG Base Directory Specification][xdg] for configuration files.
Because this module is intended to find consistently named configuration files, it is case-sensitive and does not support globs. If you need a more generic solution, see [findup-sync][fus] or [look-up][lku].
[fus]: https://www.npmjs.com/package/findup-sync
[lku]: https://www.npmjs.com/package/look-up
[xdg]: http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
## Algorithm
Where X is the current directory:
1. If X/file.ext exists, return it. STOP
2. If X/.dir/file.ext exists, return it. STOP
3. If X has a parent directory, change X to parent. GO TO 1
4. Return NULL.
## Install
With [Node.js](http://nodejs.org):
$ npm install find-config
## Usage
```js
var findConfig = require('find-config');
// Find the path to the nearest `package.json`
var pkg = findConfig('package.json');
// Find the path to the nearest `.foorc` or `.config/foorc`
var foo = findConfig('.foorc');
// Find the path to the nearest `.foorc` or `.config/.foorc`
var foo = findConfig('.foorc', { dot: true });
// Find the path to the nearest module using Node.js module resolution.
// Will look for `bar.js` or `bar/index.js`, etc.
var foo = findConfig('bar', { module: true });
// Find the path to the nearest `baz.json` or `some/path/baz.json`
var foo = findConfig('baz.json', { dir: 'some/path' });
// Find the path to the nearest `qux.json` or `some/path/qux.json` in
// some other directory or its nearest ancestor directory.
var foo = findConfig('qux.json', { cwd: '/other/dir', dir: 'some/path' });
// Find and require the nearest `package.json`
var pkg = findConfig.require('package.json');
// Find and read the nearest `.foorc` or `.config/foorc`
var foo = findConfig.read('.foorc');
```
## API
### `findConfig(filename, [options]) : String|Null`
- `filename` `String` - Name of the configuration file to find.
- `options` `{Object=}`
- `cwd` `{String=}` - Directory in which to start looking. (Default: `process.cwd()`)
- `dir` `{String=}` - An optional subdirectory to check at each level. (Default: `'.config'`)
- `dot` `{Boolean=}` - Whether to keep the leading dot in the filename in `dir`. (Default: `false`)
- `home` `{Boolean=}` - Whether to also check the user's home directory. (Default: `true`)
- `module` `{Boolean=}` - Whether to use Node.js [module resolution][modres]. (Default: `false`)
Synchronously find the first config file matching a given name in the current directory or the nearest ancestor directory.
[modres]: https://nodejs.org/api/modules.html#modules_all_together
### `findConfig.obj(filename, [options]) : Object|Null`
- `filename` `String` - Name of the configuration file to find.
- `options` `{Object=}` - Same as `findConfig()`.
Finds first matching config file, if any and returns the matched directories and config file path.
### `findConfig.read(filename, [options]) : String|Null`
- `filename` `String` - Name of the configuration file to find.
- `options` `{Object=}` - Same as `findConfig()` with two additions.
- `encoding` `{String}` - File encoding. (Default: `'utf8'`).
- `flag` `{String}` - Flag. (Default: `'r'`).
Finds and reads the first matching config file, if any.
```js
var yaml = require('js-yaml');
var travis = yaml.safeLoad(findConfig.read('.travis.yml'));
```
### `findConfig.require(filename, [options]) : *`
- `filename` `String` - Name of the configuration file to find.
- `options` `{Object=}` - Same as `findConfig()`.
Finds and requires the first matching config file, if any. Implies `module` is `true`.
```js
var version = findConfig.require('package.json').version;
```
