validate-env

Validate your env variables

Avoid the scenerio where your app doesn't work properly because you're missing an environment variable.

Installation

$ npm install validate-env --save
# ... or 
$ yarn add validate-env
 

Usage Examples:

1. First option is to use validateEnvVariables default functionality, which throws an Error on failure.

const { validateEnvVariables } = require('validate-env');
 
try {
    validateEnvVariables(['GOOGLE_API_KEY', 'AWS_SECRET_KEY']);
} catch (error) {
    console.error(error);
    process.exit(1);
}
 

2. Or you can disable throwsOnFailure functionality, meaning validateEnvVariables will now return false when env variables are invalid.

const { validateEnvVariables } = require('validate-env');
 
if (!validateEnvVariables(['GOOGLE_API_KEY', 'AWS_SECRET_KEY'], { throwsOnFailure: false })) {
    console.log('One or more env vars are missing!');
    process.exit(1);
}
