@flashfix/config v1.0.2

@flashfix/config

Shared config for universal JavaScript apps.

Loads configs in a certain order, next config always overriding previous one. Performs a deep merge of nested properties.

To use this module create a config folder next to your node_modules folder with one of the following files (loaded in this order):

1. default.js
2. mycustomenv.js where mycustomenv is what you would set NODE_ENV to
3. local.js

Defaults:

By default config object is supplied with the following properties:

• environment is the value of NODE_ENV environment variable or 'development'
• debug is true if environment is development
• sandbox is true if SANDBOX environment variable is set to true or debug is true

Options:

All options can be set in the process environment:

• NODE_ENV sets node environment, default: development
• SANDBOX sets sandbox mode, default: (empty), accepts: true
• CONFIG_DIR sets the name/path to config folder, relative to the project root, default: config

Usage:

const config = require('@flashfix/config');
// use your config

There is a special ConfigPlugin for Webpack to bundle config in your client app:

const ConfigPlugin = require('@flashfix/config/plugin');
// ...
plugins: [
  new ConfigPlugin(options),
],

ConfigPlugin accepts an options object:

const options = {
  // An optional function to filter full config and hide secrets from the client app.
  // By default entire config object will be accessible to the client.
  // It's highly recommended to pass this function to filter your full config and only output
  // client relevant portions preserving original object structure.
  getConfig: (fullConfig) => {
    const { clientSafePortion } = fullConfig;
    const configWithoutSecrets = { clientSafePortion };
    return configWithoutSecrets;
  },
  // An optional boolean flag that switches internal loader output
  // between ES Module (default) and Common JS format
  esModule: true,
};
