EnvForge

Description

envForge is an npm package that simplifies the process of defining and validating environment variable schemas in your Node.js applications. With envForge, you can easily define a schema for your environment variables and ensure that your application's configuration meets the required specifications.

Installation

To install envForge, use npm:

npm install envForge

or 

yarn add envForge

Getting Started

const envForge = require('envForge');

Define schema

const defaultSchema = new EnvForge({path:"./.env"});

    API_URL:[
        "required",
    ],
    S3_BUCKET_URL:[
        "required"
    ]
});

// Will validate, if any error will throw an error
defaultSchema.validate();

How to access keys

// You can get all keys
defaultSchema.getAllKeys()

// You can get keys that defined in ur .env file
defaultSchema.getParsedKeys();

API Reference

Current Validations

Example

Required

defaultSchema.createSchema({
    API_URL:[
        "required",
    ],
    S3_BUCKET_URL:[
        "required"
    ]
});

Boolean

defaultSchema.createSchema({
    IS_DEVELOPMENT:[

    ],
});

isArray

defaultSchema.createSchema({
    DATA:[

defaultSchema.createSchema({
    ENVS:[
        "isin:DEV,STAGE,PROD",
    ],
});

Other

1. prefixWithKeys

// To prefix all the keys with "REACT_"
defaultSchema.createSchema({
  API_URL:[
    "required",
  ],
},{
  prefixKeysWith:"REACT_",
});

2. totalKeys

defaultSchema.createSchema({
  API_URL:[
    "required",
  ],
},{
  totalKeys:10,
});

// This will make sure total keys in environment variable must be 10.

3. strict

defaultSchema.createSchema({
  API_URL:[
    "required",
  ],
},{
  totalKeys:10,
  strict:true
});

// Strict option gets with totalKeys, setting it true make sure that totalKeys are exact number.
