deanc/gatsby-source-firestorer

Gatsby source plugin for building websites using the Firestore as a data source. Forked from a couple of other versions and updated to use latest Gatsby params.

Authentication

You have two ways to authenticate to Firebase.

(Reccommended) Supply a valid firebaseConfig object with read-only credentials. Instructions here.
Get a private key for your Firebase project from the Firebase console.

Usage

Method 1: Standard web SDK (Reccommended)

Supply a valid firebaseConfig object
$ yarn add @deanc/gatsby-source-firestore
Configure gatsby-config.js

module.exports = {
  plugins: [
    {
      resolve: '@deanc/gatsby-source-firestore',
      options: {
        config: {
          apiKey: 'api-key',
          authDomain: 'project-id.firebaseapp.com',
          databaseURL: 'https://project-id.firebaseio.com',
          storageBucket: 'yourapp.appspot.com',
          projectId: 'project-id',
          messagingSenderId: 'sender-id',
          appId: 'app-id',
          measurementId: 'measurement-id',
        },
        types: [
          {
            type: 'Book',
            collection: 'books',
            map: doc => ({
              title: doc.title,
              isbn: doc.isbn,
              author___NODE: doc.author.id,
            }),
          },
          {
            type: 'Author',
            collection: 'authors',
            map: doc => ({
              name: doc.name,
              country: doc.country,
              books___NODE: doc.books.map(book => book.id),
            }),
          },
        ],
      },
    },
  ],
};

Method 2: Firebase Admin SDK

Get a private key for your Firebase project.
Put that private key somewhere in your Gatsby project.
$ yarn add @deanc/gatsby-source-firestore
Configure gatsby-config.js

module.exports = {
  plugins: [
    {
      resolve: '@deanc/gatsby-source-firestore',
      options: {
        credential: require('./firebase.credentials.json'),
        types: [
          {
            type: 'Book',
            collection: 'books',
            map: doc => ({
              title: doc.title,
              isbn: doc.isbn,
              author___NODE: doc.author.id,
            }),
            conditions: [['status', '==', 'public']], // optional
          },
          {
            type: 'Author',
            collection: 'authors',
            map: doc => ({
              name: doc.name,
              country: doc.country,
              books___NODE: doc.books.map(book => book.id),
            }),
          },
        ],
      },
    },
  ],
};

Querying

To query

  allBooks {
    edges {
