# With Firebase Authentication example
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-firebase-authentication with-firebase-authentication-app
|
|
# or
|
|
yarn create next-app --example with-firebase-authentication with-firebase-authentication-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-firebase-authentication
|
|
cd with-firebase-authentication
|
|
```
|
|
|
|
Set up firebase:
|
|
- Create a project at the [Firebase console](https://console.firebase.google.com/).
|
|
- Get your account credentials from the Firebase console at *settings>service accounts*, where you can click on *generate new private key* and download the credentials as a json file. It will contain keys such as `project_id`, `client_email` and `client id`. Now copy them into your project in the `credentials/server.js` file.
|
|
- Get your authentication credentials from the Firebase console under *authentication>users>web setup*. It will include keys like `apiKey`, `authDomain` and `databaseUrl` and it goes into your project in `credentials/client.js`.
|
|
- Copy the `databaseUrl` key you got in the last step into `server.js` in the corresponding line.
|
|
- Back at the Firebase web console, go to *authentication>signup method* and select *Google*.
|
|
|
|
Install it and run:
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
# or
|
|
yarn
|
|
yarn dev
|
|
```
|
|
|
|
Deploy it to the cloud with [now](https://zeit.co/now) ([download](https://zeit.co/download))
|
|
|
|
```bash
|
|
now
|
|
```
|
|
|
|
## The idea behind the example
|
|
The goal is to authenticate users with firebase and store their auth token in sessions. A logged in user will see their messages on page load and then be able to post new messages.
