Angular SSR (Server-side Rendering) using Google Cloud Functions (GCF)

A demo/experiment of deploying an Angular 6 SSR app using Google Cloud Functions together with Firebase Hosting.

Getting Started

This repo consists of three branches:

• master: the simpelst Angular SSR app that can be deployed to Firebase using GCF and Firebase Hosting.
• angularfire: the extension of master branch with angularfire2 and usage of RTDB on Firebase. This version of the app can also be deployed to Firebase using GCF and Firebase Hosting and should work as entented.
• admin: the extension of angularfire branch with usage of firebase-admin package which is initialized in the index.js file and the RTDB is used in the demo function. This version of the app can also be deployed to Firebase using GCF and Firebase Hosting and should work as entented.

NOTE: both the admin as well as angularfire branch requires Firebase web config object in order to be deployed or served locally. Check the environment.ts and environment.prod.ts files under pwa/src/environments folder.

Building

Build the SSR app using the following command from the pwa folder:

$ npm run build:ssr

Running Locally

Run the app locally with SSR using the following command from the root folder of the project.

$ firebase deploy --only functions,hosting

Deploying

In order to deploy the app use the following command from the root folder of the project:

$ firebase deploy --only functions,hosting

Results

This experiment helped me find out the issue with Angular Universal not working on GCF. What I found was the fact that Firebase SDK will not allow initialization of two "connections" to the RTDB, i.e. one from angularfire2 and another through firebase-admin.
