Hello!
I was looking at the [`with-firebase-hosting`](/zeit/next.js/tree/canary/examples/with-firebase-hosting) example and was having some various issues running it:
* `npm run serve` will choke on windows because trying to set enviroment variables with `NODE_ENV=production`
* `npm run build-funcs` failing because of babeljs mismatches between `@babel/cli@^7.0.0-rc.1` and `next@^6.0.3`
* Not being able to deploy because `firebase-tools` being a deprecated version.
I remedied this and also improved some other factors:
* Use standard JSON formatting on `package.json` so that `npm install` doesn't cause changes on every run. (a83e930)
* Remove "prettier" as a devDependency as there is no use of it in the example and most other examples does not have it as a dependency. (6095663)
* Update all dependencies. The simple usecase in this example didn't really require any changes to the code. (ccde086)
* [`firebase-admin@6`](https://github.com/firebase/firebase-admin-node/releases/tag/v6.0.0)
* [`firebase-functions@2`](https://github.com/firebase/firebase-functions/releases/tag/v2.0.0)
* [`firebase-tools@4`](https://github.com/firebase/firebase-tools/releases/tag/v4.0.0)
* [`firebase-tools@5`](https://github.com/firebase/firebase-tools/releases/tag/v5.0.0)
* [`firebase-tools@6`](https://github.com/firebase/firebase-tools/releases/tag/v6.0.0)
* Make `npm run serve` runnable on windows using [`cross-env`](https://www.npmjs.com/package/cross-env). (b20dda7)
* Update `.gitignore` to ignore firebase cache (bf761b7)
* Remove `src/app/.babelrc` that seems to have been added as a previous bugfix but doesn't seem to do anything currently. (1b02045)
* Remove point from [`README.md`](https://github.com/zeit/next.js/blob/canary/examples/with-firebase-hosting/README.md) that was mentioning any `predeploy` hooks in `firebase.json` as they were removed in

With Firebase Hosting example
How to use
Using create-next-app
Execute create-next-app with Yarn or npx to bootstrap the example:
npx create-next-app --example with-firebase-hosting with-firebase-hosting-app
# or
yarn create next-app --example with-firebase-hosting with-firebase-hosting-app
Download manually
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
cd with-firebase-hosting
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/<projectId> - update the
.firebasercdefault project ID to the newly created project - login to the Firebase CLI tool with
firebase login
Install Project
npm install
Run Next.js development:
npm run dev
Run Firebase locally for testing:
npm run serve
Deploy it to the cloud with Firebase:
npm run deploy
Clean dist folder
npm run clean
The idea behind the example
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. 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 at https://github.com/geovanisouza92/serverless-firebase & https://github.com/jthegedus/firebase-functions-next-example as described here.
If you're having issues, feel free to tag @jthegedus in the issue you create on the next.js repo
Important
- The empty
placeholder.htmlfile is so Firebase Hosting does not error on an emptypublic/folder and still hosts at the Firebase project URL. firebase.jsonoutlines the catchall rewrite rule for our Cloud Function.- Specifying
"engines": {"node": "8"}in thepackage.jsonis required for firebase functions to be deployed on Node 8 rather than Node 6 (Firebase Blog Announcement) . This is matched insrc/functions/.babelrcso that babel output somewhat compacter and moderner code.
Customization
Next App and Next Server development are separated into two different folders:
- app -
src/app/ - server -
src/functions/
If you wish to modify any configuration of the Next App, you should only modify the contents of src/app.
For instance, the .babelrc in src/functions is used only to compile the Firebase Cloud Functions code, which is our the Next Server code. If you wish to customize the .babelrc for the Next App compilation, then you should create one at src/app/.babelrc and follow the customization guide.
_app.js
If using _app.js you may receive the following error on your deployed Cloud Function:
{ Error: Cannot find module '@babel/runtime/regenerator'...
Despite next.js having @babel/runtime as a dependency, you must install it as a dependency directly in this project.
