Envokin

• Envokin is a powerful and intuitive environment variable validation library for Node.js applications.
• Designed to ensure the integrity and correctness of your environment configurations, Envokin simplifies the process of validating environment variables, making your application more robust and secure.

Usage

Base syntax

const envokin = new Envokin(schema, options)

• schema- An object that specifies the format of required vars
• options - An (optional) object, which supports the following keys:
  • source - Can be an object or path to file (.json, .env).
  • strict - Boolean value, default is false

If the source key is not provided in the options, Envokin will use the variables from process.env for validation. If the strict flag is set to true in the options, a ValidationError will be thrown if a value for a key from the schema is not provided in the environment variables.

Basic Usage

import { Envokin } from 'envokin'

const envokin = new Envokin({
 HOST: 'host',
 PORT: 'port',
 URL: 'url',
 EMAIL: 'email',
 IP: 'ip',
 IP4: 'ip4',
 IP6: 'ip6',
 STRING: 'string',
 NUMBER: 'number',
 BOOLEAN: 'boolean',
 JSON: 'json',
 CUSTOM_VALUE: {
     validator: (_: string, value: unknown): boolean => typeof value === 'string',
     transformer: (value: unknown): string => String(value).toUpperCase()
   }
});

envokin.get('EMAIL'); // -> A string value containing a valid email
envokin.get('PORT'); // -> A number value containing a valid port
envokin.isDev; // true if NODE_ENV === 'dev' | 'develop' | 'development'
envokin.isTest; // true if NODE_ENV === 'test' | 't'
envokin.isProduction; // true if NODE_ENV == 'production' | 'prod'
