    Getting started

    1. Install
    npm install configuru
    1. Create .env.jsonc in root of your project, add defaults or placeholders.
      // HTTP server
      "SERVER_PORT": 3000 // port the server will be listening on
    1. (optional) As a developer (or environment), create a custom override file (e.g. ~/.env/my-project.jsonc) and save the path in your CFG_JSON_PATH.

    2. Create a configuration module (e.g. config.ts)

    import { createLoader, values } from 'configuru'
    // create loader that cascades overrides and creates a config storage
    const loader = createLoader()
    // Pass configuration schema to `values` transformer to get configuration
    export default values({
      server: {
        // use loader accessors, place them in custom structure
        // loader parses correct type from store
        port: loader.number('SERVER_PORT'),
    1. Use your configuration params throughout your app
    import config from './config' // e.g. { server: { port: 3000 } }
    console.log(config.server.port) // 3000
