Lilconfig ⚙️

A zero-dependency alternative to cosmiconfig with the same API.

Installation

npm install lilconfig

Usage

import {lilconfig, lilconfigSync} from 'lilconfig';

// all keys are optional
const options = {
    stopDir: '/Users/you/some/dir',
    searchPlaces: ['package.json', 'myapp.conf.js'],
    ignoreEmptySearchPlaces: false
}

lilconfig(
    'myapp',
    options // optional
).search() // Promise<LilconfigResult>

lilconfigSync(
    'myapp',
    options // optional
).load(pathToConfig) // LilconfigResult

/**
 * LilconfigResult
 * {
 *   config: any; // your config
 *   filepath: string;
 * }
 */

ESM

ESM configs can be loaded with async API only. Specifically js files in projects with "type": "module" in package.json or mjs files.

Difference to cosmiconfig

Lilconfig does not intend to be 100% compatible with cosmiconfig but tries to mimic it where possible. The key difference is no support for yaml files out of the box(lilconfig attempts to parse files with no extension as JSON instead of YAML). You can still add the support for YAML files by providing a loader, see an example below.

Options difference between the two.

cosmiconfig option	lilconfig
cache	✅
loaders	✅
ignoreEmptySearchPlaces	✅
packageProp	✅
searchPlaces	✅
stopDir	✅
transform	✅

Loaders examples

Yaml loader

If you need the YAML support you can provide your own loader

import {lilconfig} from 'lilconfig';
import yaml from 'yaml';

function loadYaml(filepath, content) {
    return yaml.parse(content);
}

const options = {
    loaders: {
        '.yaml': loadYaml,
        '.yml': loadYaml,
        // loader for files with no extension
        noExt: loadYaml
    }
};

lilconfig('myapp', options)
    .search()
    .then(result => {
        result // {config, filepath}
    });
