# Introduction

All of the configuration files for Firelayer are stored in the config directory.

If they don't exist already, start by copying all the *.dist.json files and rename to *.json in their respective folder and fill out with the respective configurations content:

# > config/keys/key.json

It's the service account key downloaded from the firebase console which will allow access the Admin SDK functionalities for the Firelayer CLI and for apps/functions local development.

# > config/app.json

This is the global configuration file, all applications will receive these configs. A good example of what to inject into all the applications would be the Firebase config.

# > config/{folder}/env.json

Each folder contains the configuration file for the respective apps/{folder} application. Configurations set in these files will ovewrite config/app.json properties (when the keys are the same).

# Using

The configurations are intended to be used with the help of the command firelayer run which will inject all the configurations into process.env

So when running firelayer run "node index.js" it will inject all the configurations into process.env, like so:

// will create a key for each app in apps/{folder} // stringified version of config files // config/admin/env.json + config/app.json process.env.admin = '{"firebase": {"projectId": "new-firebase-project"}}' // config/functions/env.json + config/app.json process.env.functions = '{"firebase": {"projectId": "new-firebase-project"}}' // config/app.json is injected in all applications // because is the global configuration file for the project // and the path for the the Service Account key process.env.GOOGLE_APPLICATION_CREDENTIALS = '..../config/keys/key.json' // so it can be used in the initialization of the Firebase Admin SDK // like so: admin.credential.applicationDefault()
