# Authentication

You have two ways to authenticate to Firebase.

1. (Recommended) Supply a valid firebaseConfig object with read-only credentials. [Instructions here](https://support.google.com/firebase/answer/7015592#web).
2. Get a private key for your Firebase project from the Firebase console.

# Usage

## Method 1: Standard web SDK (Recommended)

1. Supply a valid firebaseConfig object
2. `$ yarn add @deanc/gatsby-source-firestorer`
3. Configure `gatsby-config.js`

```javascript
module.exports = {
plugins: [
{
resolve: '@deanc/gatsby-source-firestorer',
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,
}),
conditions: [['status', '==', 'public']], // optional
},
{
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

1. Get a private key for your Firebase project.
2. Put that private key somewhere in your Gatsby project.
3. `$ yarn add @deanc/gatsby-source-firestorer`
4. Configure `gatsby-config.js`

```javascript
module.exports = {
plugins: [
{
resolve: '@deanc/gatsby-source-firestorer',
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

```graphql
{
allBooks {
edges {
node {
title
isbn
author {
name
}
}
}
}
}
```
