Validate your env variables, avoiding future headaches or points of failure!

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);
}
