rcload

Find and load json configuration from a package.json property, rc file, or CommonJS module.

Heavily inspired by cosmiconfig, but super simplified for minimal bundlesize.
The big difference from cosmiconfig is that rcload does not support yaml files.

rcload will search for the following:

• a package.json property
• a JSON extensionless "rc file"
• an "rc file" with the extensions .json or .js
• a .config.js CommonJS module

It is also meant as a partial drop-in replacement which means it return a result object same as cosmiconfig.

Differences from cosmiconfig

• Supports only JSON and CommonJS formats.
• Only looks in process.cwd().
• Limited options.
• Only synchronous load.

Usage

Install as a dependency.

npm i rcload

Use in your application.

const rcload = require('rcload');

const result = rcload('myapp');

Result

The result object has the following properties:

• config: The parsed configuration object. undefined if the file is empty.
• filepath: The path to the configuration file that was found.
• isEmpty: true if the configuration file is empty.

In contrast to cosmiconfig, isEmpty will remain in the result object when the config is found, e.g.:

const result = rcload('myapp');
// {
//     config: {
//         ...
//     },
//     filepath: "/users/johndoe/www/myapp/.myapprc",
//     isEmpty: false
// }

Options

rcload takes an options object:

• cwd: the full directory path to search in. Common for package.json and rc files. Defaults to process.cwd().

If you want your config files in another directory this will help, e.g.:

rcload('myapp', {
    cwd: path.join(process.cwd(), 'configs')
})
