Documentation

env-and-files

Load configuration from environmental variables and files.

According to The Twelve-Factor App, configuration should come from environmental variables. But since environmental variables can leak easily, some people use secrets for sensitive information. This module is made to support either with minimal set-up.

Install

npm install env-and-files

Or, with yarn:

$ yarn add env-and-files

Usage

const {loadConfig} = require('env-and-files');

loadConfig({
  postgresPassword: {
    filePath: '/secrets/password',
  },
  postgresUrl: {
    format: (value) => new URL(value),
    variableName: 'POSTGRES_URL',
  },
  postgresUsername: {
    defaultValue: 'postgres',
    filePath: '/secrets/username',
  },
})
  .then((config) => {
    // "config" will be an object map of configuration properties.
    console.log(config);
  })
  .catch((error) => {
    // If any of the required properties cannot be loaded, the Promise will reject.
    console.error(error);
  });
