Find, load and merge JSON and YAML config settings from one or more files, in the specified order.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your ❤️ and support.

Install with npm:

$ npm install --save merge-configs

This library makes it easy for your application to support config files similar to .eslintrc.json, .travis.yml, etc. by providing granular control over:

• the patterns and directories to search for config files
• how config files are loaded (or whether or not they should be loaded at all)
• which config files are merged, and how they are merged

const configs = require('merge-configs');
console.log(configs(name[, locations, options]));

Type: boolean

Default: undefined

Disable built-in loaders.

const mergeConfig = new MergeConfig({
  options: {
    builtins: false
  }  
});

Type: function

Default: undefined

Filter files that are resolved by glob patterns. Useful for conditionally filtering out files based on contents or other variables.

// can be defined on the ctor options
const mergeConfig = new MergeConfig({
  options: {
    filter: file => {
      // "file" is an object with path properties
      return file.basename === 'foo.json'
    }
  }  
});

// or on the options for a specific config type
mergeConfig.type('local', {
  cwd: process.cwd(),
  patterns: ['*.json'],
  filter: file => {
    return file.basename !== 'foo.json';
  }
});

• name {String} - (required) The module name (example: eslint, babel, travis etc)
• types {Array} - (optional) The config locations or "types" to search. If specified, only the given locations will be searched. If undefined, all locations are searched.
• options {Object} - see all available options
