Setup Instructions

The setup will automatically take care of configurations and credentials. If you would instead prefer to do it all manually, Click here.

Prerequisite: A firebase project.

1. Install the package

npm install firebase-nextjs

2. Run the setup script

npx firebase-nextjs setup

This will

Prompt you to log in with Google.
You will be asked to select the firebase project you wish to use.
You will be asked to choose the service account you wish to use. ("firebase-admin-sdk" is recommended)
Choose an app you wish to use. (Must be a web app) (If an app doesn't exist, you can create it there.)
This will generate the necessary authentication credentials, and store it to the project.
With this, basic setup is complete.

3. Setup firebase-nextjs Provider

In the root layout file, (layout.jsx), wrap the whole body in <FirebaseNextJSProvider>

import {FirebaseNextJSProvider} from "firebase-nextjs/client/auth";


<html lang="en">
    <FirebaseNextJSProvider>
        <body className={inter.className}>{children}</body>
    </FirebaseNextJSProvider>
</html>

4. Thats it! Run the project.

npm run dev

This will require you to sign in to continue. You can use Google Sign In or Email Password Sign In.

For Developers

If you wish to contribute or make changes to the package, follow the below guide

Step 1: Fork and clone the repo

Fork the repo to your profile and clone the repo locally.

Step 2: Build the package

Run the command

npm run build

This will create a folder 'build' in the directory. It will contain the actual package that you should be using.

Step 3: Link the package to your project

Create a nextjs project that you wish to test the package with. (Or use your existing NextJS project). Copy the location of the build directory generated from the previous step.

Run the command

npx link /path/to/build/folder/of/firebase-nextjs

Step 4: Use the package

Now, the package is linked to your project, and it is exactly as if you have installed the package. Do not add the package name to package.json.

To use the package in your project, You can import the files just like you would form an installed package.

Example:

import { ProfileButton } from "firebase-nextjs/client/components";

To use the npx script You can run the npx script as usual, and the code in your build folder will be used.

npx firebase-nextjs getenev

Step 5: Modifications

After you make any modification to the source code, run

npm run build

Thats it and your project will be using the newly built package.

NOTE: Installing other packages

Whenever you use the command npm install packagename to install any package, the npx link will be removed. Re run the npx command to link to the build directory again.
