Ghost Firebase Storage Adapter

This a Firebase Storage adapter for Ghost CMS. Images uploaded via Ghost CMS will be save to Firebase Storage.

Prerequisite

• Have a Firebase Project with Firebase Storage enabled.
• Generate Private key for your Firebase Service Account - Instructions

Setup

Installation

At the root of you ghost blog, install this adapter using either npm or yarn.

NPM

npm i ghost-firebase-storage-adapter

Yarn

yarn add ghost-firebase-storage-adapter

Create Firebase Storage Module

After installation, a scripts runs that automatically creates a storage adapter in the content/adapters/storage directory, named firebase.js with the following content:

'use strict'

module.exports = require('ghost-firebase-storage-adapter');

NB: if the firebase.js was not created, create it in the content/adapters/storage directory and add the above content.

Configurations

Before we can proceed, make sure you have the bucket-name, without any prefix (gs://) or suffix (.appspot.com) and your Firebase Service Account Private Key, a json file.

• Add the json file containing the private key to the root of you ghost directory or somewhere else more secure.
• Add a storage block to your config.${GHOST_ENVIRONMENT}.json as shown below:

"storage": {
    "active": "firebase",
    "firebase": {
        // configurations for the storage adapter
        "serviceAccount": "./path/to/service/account.json",
        "bucketName": "bucket-name",
        "basePath": "base path for saving uploads",
        "uploadOptions": {
            "gzip": true,
            "metadata": {
                "cacheControl": "public, max-age=31536000"
            }
        }
    }
}

For more information, see the example config here.
