The goal is to host the Next.js app on Firebase Cloud Functions with Firebase Hosting rewrite rules so our app is served from our Firebase Hosting URL, with a complete Typescript stack for both the Next app and for the Firebase Functions. Each individual page bundle is served in a new call to the Cloud Function which performs the initial server render.

This is based off of the work of @jthegedus in the with-firebase-hosting example.

If you're having issues, feel free to tag @sampsonjoliver in the issue you create on the next.js repo

Execute create-next-app with npm or Yarn to bootstrap the example:

npm init next-app --example with-firebase-hosting-and-typescript with-firebase-hosting-and-typescript-app
# or
yarn create next-app --example with-firebase-hosting-and-typescript with-firebase-hosting-and-typescript-app

Download the example:

curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-firebase-hosting-and-typescript
cd with-firebase-hosting-and-typescript

Set up firebase:

• install Firebase Tools: npm i -g firebase-tools
• create a project through the firebase web console
• grab the projects ID from the web consoles URL: https://console.firebase.google.com/project/
• update the .firebaserc default project ID to the newly created project
• login to the Firebase CLI tool with firebase login

npm install

npm run dev

npm run serve

npm run deploy

npm run clean

• The empty placeholder.html file is so Firebase Hosting does not error on an empty public/ folder and still hosts at the Firebase project URL.
• firebase.json outlines the catchall rewrite rule for our Cloud Function.
• The Firebase predeploy hooks defined in firebase.json will handle linting and compiling of the next app and the functions sourceswhen firebase deploy is invoked. The only scripts you should need are dev, clean and deploy.
• Specifying "engines": {"node": "8"} in the package.json is required for firebase functions to be deployed on Node 8 rather than Node 6 (Firebase Blog Announcement) . This is matched in by specifying target as es2017 in src/functions/tsconfig.json so that typescript output somewhat compacter and moderner code.
