Next.js SSR app on Cloud Functions for Firebase with Firebase Hosting

Host a Next.js SSR React app on Cloud Functions for Firebase with Firebase Hosting.

Here is the accompanying Medium Post A new post is being written to describe the new project structure, Firebase partial deployments, Firebase support of pre/post-deploy hooks and what problems these new features solve.

Why?

Host your SSR Next.js app on Cloud Functions enabling a low-cost, auto-scaling SSR app experience leveraging Firebase's sweet developer experience.

How?

Firebase Hosting can rewrite routes to a Cloud Function that serves our Server-side Rendered Next.js app. Using a rewrite rule that catches ALL routes we can then host our SSR app on our Firebase Hosting URL instead of the Firebase Cloud Function URL.

instead of:

https://us-central1-<project-name>.cloudfunctions.net/<function-name>

we can use:

<project-name>.firebaseapp.com/

Next.js can then be used to achieve SSR React with Hot-Module Reloading, server and client-side routing, route level code-splitting, route prefetching and more!

A number of issues with Hosting SSR on Firebase were overcome with this method. Please refer to the Medium Post before creating issues here.

Important!

This example uses firebase-tools as a devDependency which is run from the node_modules/.bin/ folder via yarn. Yarn will run scripts from either the package.json or binary scripts from node_modules/.bin/. npm run does not check the .bin folder for executables, so if you use npm you will either have to change the scripts to explicitly run the firebase binary from node_modules/.bin/ or install firebase-tools globally and remove it from the devDeps list.

Installation

git clone https://github.com/jthegedus/firebase-functions-next-example
cd firebase-functions-next-example
yarn install

Login to Firebase CLI

This is used as a dev-dependency instead of a global install. I've found this to be a much nicer dev experience.

yarn fblogin

Next.js Development

Standard Next.js development with Hot-module Reloading etc

yarn dev

Local Testing

Unfortunately I have been unable to get any combination of

firebase serve --only functions,hosting

to work as expected. This issue is where solutions are being explored and they will be shared here and on the Next.js repo's similar issue when discovered.

In the meantime you'll just have to do a full deployment and test online. The new project structure of v2.0.0 and partial deployments reduces the deployment time significantly so this is not too bad. I'm continually looking into a solution to this.

Deploy to Firebase

You will need to connect the project to your Firebase project. Edit the name in .firebaserc or run firebase init and choose not to override any files.

Deploy Hosting resources and the rewrite Cloud Function

yarn deploy-app

Deploy functions not used for the SSR

Deploy all functions specified in the function group. Edit this script to add more function groups. - see Partial deploys docs for how to use function groups.

yarn deploy-funcs

Deploy everything to Firebase

yarn deploy-all

Clean dist Folder

yarn clean

A note on Code Compatibility

Everything was tested on Ubuntu 17.04 with Bash. This should work on Bash on Ubuntu on Windows without any changes. If you wish for Windows native support please submit an issue so we can work on Windows compatibility. Please report any macOS errors as I do not have access to a device to test. My development environment can be found here.
