apollo-datasource-firebase

Connect your GraphQL server to Google Firebase using DataSources.

Firebase Data Source

Install

yarn add apollo-datasource-firebase

or

npm i apollo-datasource-firebase --save

Usage

Define a data source by extending the FirebaseDataSource class. You can then implement the queries and mutations that your resolvers require.

Create a configuration object or json file with the following format to initialise the Firebase and Firebase Admin APIs.

firebaseConfig.json

{
  "firebaseOptions": {
    "apiKey": "<application-api-key>",
    "authDomain": "<project-id>.firebaseapp.com",
    "databaseURL": "https://<project-id>.firebaseio.com",
    "projectId": "<project-id>",
    "storageBucket": "<project-id>.appspot.com",
    "messagingSenderId": "<messaging-sender-id>",
    "appId": "<app-id>",
    "measurementId": "<measurement-id>"
  },
  "serviceAccount": {
    "type": "service_account",
    "project_id": "<project-id>",
    "private_key_id": "<private-key-id>",
    "private_key": "<private-key>",
    "client_email": "<service-account-email>",
    "client_id": "<client-id>",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_x509_cert_url": "client-x509-cert-url"
  },
  "databaseURL": "https://<project-id>.firebaseio.com" 
}
