Configuration

Configurations are stored in the environment variables, and will be validated when the server is initialized.

We store the enviroment variables in the .env file. E.g.

PORT=3000

Validation can be carried out in the config.js file before exporting the configs. In this example, we use the library convict for validating the configs, and setting the defaults if the config is not available in the enviroment variables.

// config.js
import convict from 'convict'

const conf = convict({
    port: {
        doc: 'The port to bind',
        format: 'port',
        default: 3000,
        env: 'PORT'
    }
})

conf.validate({ strict: true })

export default conf
