Server-side generated pages w/ Handlebars templating and user sessions

This samples shows how to serve server-side generated HTML pages using the HandlebarsJs templating system.

It also shows how to serve user specific content by passing the Firebase ID token of the signed-in user in a __session cookie.

Checking and decoding the ID token passed in the __session cookie is done with an ExpressJs middleware.

Some custom scripts in [functions/views/layouts/main.handlebars] maintain the Firebase ID token in the __session cookie.

Setting up the sample

Create a Firebase Project using the Firebase Console.
Enable the Google Provider in the Auth section.
Clone or download this repo and open the template-handlebars directory.
You must have the Firebase CLI installed. If you don't have it install it with npm install -g firebase-tools and then configure it with firebase login.
Configure the CLI locally by using firebase use --add and select your project in the list.
Install dependencies locally by running: cd functions; npm install; cd -

This sample comes with a web-based UI for testing the function. To test locally do:

Start serving your project locally using firebase serve --only hosting,functions
Open the app in a browser at https://localhost:5000.
Sign in the web app in the browser using Google Sign-In and some user information will be displayed on a server-side generated page.

To deploy and test the app on prod do:

Deploy your project using firebase deploy
Open the app using firebase open hosting:site, this will open a browser.
Sign in the web app in the browser using Google Sign-In and some user information will be displayed on a server-side generated page.
