🌍Environment variables

Multijet offers environment variable validation for microservices using Joi.

To add an environment variable to a microservice, simply edit the env.ts file located in <service-name>/src/utils/env.ts:

env.ts

import Joi from 'joi'

// add variable and corresponding type here
export type Environment = {
    ENVIRONMENT: string
}

// add validation rule for the variables defined above
export const JoiEnvironmentValidationSchema = Joi.object<Environment>()
    .keys({
        ENVIRONMENT: Joi.string().required(),
    })
    .required()
    .unknown()

If you want to run your project locally using AWS Lambda or Docker, you can specify the environment variables in the global .env file located in <project-name>/.env (the file is ignored by default for security reasons, if it does not exists you can simply create it).

Example of a simple .env file containing one variable called environment:

.env

ENVIRONMENT=dev

All the variables specified in this file will be assigned to every microservice.

With this, running your project locally will assign every environment variables needed by your microservices.
