Firebase cli change project

The Firebase CLI is a utility used to administer Firebase projects and perform tasks such as Realtime Database management tasks from the command-line of a terminal or command-prompt window. The Firebase CLI is also the method by which Firebase Cloud Functions are deployed and managed.

This chapter covers the installation of the Firebase CLI before creating and testing a simple Firebase Cloud Functions project.

Installing Node.js

The Firebase CLI is built on Node.js and, as such, the first step in installing the CLI is to set up the Node.js environment. If you do not already have Node.js installed, refer to the steps outlined in the chapter entitled Sending Firebase Cloud Messages from a Node.js Server.

Installing the Firebase Tools Package

With Node.js installed, the next step is to install the Firebase Tools package using the following npm command within a terminal or command-prompt window:

Note that on some platforms such as macOS and Linux it may be necessary to execute the above command with super user privileges:

Logging into Firebase

Before a new Cloud Functions project can be created it is necessary to sign into Firebase using the same account credentials used for access to the Firebase console. Installed as part of the Firebase Tools package is the Firebase CLI tool which can now be used to log into Firebase:

The command will prompt for permission to gather anonymous usage data before displaying a browser window within which to select the Google account associated with your Firebase development projects. Select an account and agree to the terms and conditions. Once the login is complete the panel shown in Figure 53‑1 will appear in the browser window:

Figure 53‑1

Close the browser window and return to the terminal window. To logout at any point in the future, simply execute the following Firebase CLI command:

Creating a Cloud Functions Project

The Firebase CLI is also used to create new Firebase Cloud Functions projects. For this example a project named MyCloudFunctions will be created. Begin by creating a subdirectory named MyCloudFunctions in a suitable filesystem location in which to store the project. Change directory into the new project folder and run the following command to create the project:

When executed, the initialization command will generate the following output:

Figure 53‑2

Using the up and down arrow keys on the keyboard, select the Firebase Examples project and press Enter. Select the option to install dependencies and wait for the initialization to complete.

Reviewing the Project

When the project creation is complete the project folder will contain the following files and directories:

• .firebaserc – A script file used by the firebase use command to switch between projects.

• firebase.json – The properties configuration file.

• functions/package.json – The JSON configuration file for the project containing version number and dependency information.

• functions/index.js – The source code file within which the Cloud Functions will be written.

• functions/node_modules – Contains the dependency packages defined in the package.json file.

Deploying a Simple HTTP Cloud Function

Using your preferred editor, edit the index.js file located in the functions folder. By default, the first line of the file imports the firebase-functions package. This is a standard requirement for all cloud function source files:

The remainder of the file contains a commented out example HTTP cloud function. Remove the comment markers so that the function reads as follows:

Save the file and deploy it using the following Firebase CLI command:

This command will deploy only the helloWorld function. To deploy all of the functions in the index.js file, use the following command:

Deployment of cloud functions can take a few minutes, but once the deployment is finished, the full output should read as follows:

Figure 53‑3

The final line of output contains the URL by which the cloud function will be triggered. Copy and paste this URL into a browser window and verify that the “Hello from Firebase!” message appears.

Edit the index.js file and modify the function to accept a query value as part of the URL and to output diagnostics to the log:

Redeploy the app using the Firebase CLI then open the same URL, this time adding a query value:

When the web page now loads, the new message containing the name value should appear.

Reviewing the Logs

Cloud function logs can be accessed either using the Firebase CLI, or from within the Firebase console. To view log output using the CLI, simply run the following command:

Alternatively, select the Firebase Examples project in the Firebase console and click on the Functions link in the navigation panel. The Functions Dashboard screen will list the functions currently deployed for the project together with basic runtime and execution metrics:

Figure 53‑4

Hovering over the function will display the menu dots (highlighted in the figure above). Open this menu and select the View logs option to view the log output for the function:

Figure 53‑5

Removing a Deployed Function

To withdraw a cloud function from deployment, remove it from the index.js file (or comment it out) and then run the Firebase CLI deployment command:

Firebase will detect the absence of the previously deployed function and delete it from the cloud.

Summary

Firebase Cloud Functions are deployed and managed using the Firebase CLI tool. This tool is built on Node.js and is installed using the npm command. Once installed, the Firebase CLI is used to sign into Firebase and create new Firebase Cloud Function projects. Once the project has been created, cloud functions are added to the index.js file and deployed to the cloud. In addition to outlining the installation process for Firebase CLI, this chapter also created, deployed and tested a simple HTTP cloud function.

Before you begin. Before you can set up Firebase Hosting, you need to create a Firebase project. Step 1: Install the Firebase CLI.

This deployment example refers to Firebase Hosting.

Prerequisites

Before you get started, you need to have:

Create a Firebase project

1. In the Firebase console click Add project, then select or enter a Project name.

   If you have an existing Google Cloud Platform (GCP) project, you can select the project from the dropdown menu to add Firebase resources to that project.

2. (Optional) Edit the Project ID.

   The project ID displays in publicly visible Firebase resources, for example as the default Hosting subdomain - projectID.web.app or projectID.firebaseapp.com. This is the only opportunity to change your project ID.

3. Click Continue.

4. (Optional) Set up Google Analytics for your project.

5. Click Create project (or Add Firebase, if you're using an existing GCP project).

Initialize your project

To connect your local project to your Firebase project, run the following command from the root of your local project directory:

During project initialization, from the Firebase CLI prompts:

1. Select to set up Hosting and Functions.

2. Select the Firebase project, which you have created in the previous section, to connect it to your local project directory.

3. Select JavaScript as language for writing Cloud Functions.

4. Choose whether you would like to use ESLint and install dependencies with npm (both recommended) or if you want to manage dependencies in another way.

5. Select the default directory as your public root directory. This directory is and all compiled files will be placed there.

6. Configure your site as single-page app to automatically add rewrite configurations.

   

After initialization, Firebase automatically creates and adds two files to the root of your local app directory:

• A configuration file that lists your project configuration.

• A file that stores your project aliases.

To support Cloud Functions, Firebase also adds the following structure to your project:

• : optional file containing rules for JavaScript linting.
• : npm package file describing your Cloud Functions code.
• : main source file for your Cloud Functions code.

Configuration

To start, we need to update the file with the production URL (replace the with the real Firebase project ID):

To configure Firebase deployments, we need to use a file. Normally, it would look something like this:

However, that won't work as the Custom Application does not have an after building the production bundles. To make it work, we need to compile the application first.

Compile the application

To be able to deploy the Custom Application to Firebase, the Custom Application needs to be compiled.

The command above does what we need: it compiles the using the JavaScript bundle references (after running ) and the runtime configuration. At this point the file is ready for production usage.

However, the Custom Application needs to instruct the User-Agent (the browser) to enforce certain security measures, using HTTP headers (done automatically by the application config).

Because of that, the function file cannot be defined statically. Instead, it needs to be generated programmatically when the Custom Application is built and compiled. To achieve that, we need to implement a transformer function.

Generate function using a transformer function

The command accepts an option which we can use to pass the filesystem path to our transformer function.

The purpose of the transformer function is to generate the final file given the compiled values passed to the function.

The main export of the file should be the transformer function.

With that in mind, we can implement the transformer function and write the config into the filesystem.

Adding fallback routes

Accessing the Custom Application directly at won't work, as the application requires the user to log in and thus tries to redirect to the route at the same domain.

To prevent that, we can add a dummy fallback route for the routes. This is only meant to inform the user that the Custom Application cannot be used standalone.

This route will be used as a serverless function:

Set up a Hosting Site (optional)

You can set up one or more Firebase Hosting sites in a single Firebase project. This is useful if you would like to host multiple Custom Applications on a single Firebase/GCP project.

Add an additional site directly from your Firebase Hosting page.

When you have multiple sites and you run Firebase CLI deploy commands, the CLI needs a way to communicate which settings should be deployed to each site. With deploy targets you can uniquely identify a specific site by its target name in your configuration file and in your Firebase CLI commands for testing or deploying to your sites.

To create a deploy target and apply a target name to a Hosting site, run the following CLI command from the root of your project directory:

Where the parameters are:

• target-name: a unique identifier (that you've defined yourself) for the Hosting site that you're deploying to.

• resource-name: the name of the Hosting site as listed in your Firebase project.

The settings for deploy targets are stored in the file in your project directory, so you only need to set up deploy targets once per project.

The assets compiled into the directory will be deployed to Firebase.

Deployment

Finally, we can trigger the deployment using the Firebase CLI:

Now you're ready to Register your Custom Application and start using it!

I may be wrong but it seems that the original question was about changing apps within a given project, rather than simply changing projects.

This answer is about changing apps and site_IDs within a project.

In my case I have a project (CoolProject) with 2 web apps:

• an assessment form:
• a main website:

Both apps are in separate repos both locally and in GitHub.

Each app has its own specific site_ID:

• form:
• website:

I first setup the app and deployed without any issue to . But when I created the app (and associated site_ID) and tried to deploy it using or it incorrectly deployed it to overwriting the app.

This is how I eventually solved the issue (based on this Firebase documentation):

1. Check that both apps and corresponding site_IDs are correctly setup:

1. Setup up the deploy target for hosting (via )

1. Update (for the app):

1. Deploy

With this the app is now correctly deployed to .

The Firebase Command Line Interface (CLI) Tools can be used to test, manage, and deploy your Firebase project from the command line.

• Deploy code and assets to your Firebase projects
• Run a local web server for your Firebase Hosting site
• Interact with data in your Firebase database
• Import/Export users into/from Firebase Auth

To get started with the Firebase CLI, read the full list of commands below or check out the documentation.

Installation

Node Package

You can install the Firebase CLI using npm (the Node Package Manager). Note that you will need to install Node.js and npm. Installing Node.js should install npm as well.

To download and install the Firebase CLI run the following command:

This will provide you with the globally accessible command.

Standalone Binary

The standalone binary distribution of the Firebase CLI allows you to download a executable without any dependencies.

To download and install the CLI run the following command:

Commands

The command lists the available commands and shows more details for an individual command.

If a command is project-specific, you must either be inside a project directory with an active project alias or specify the Firebase project id with the flag.

Below is a brief list of the available commands and their function:

Configuration Commands

Append to login (i.e., ) to copy and paste code instead of starting a local server for authentication. A use case might be if you SSH into an instance somewhere and you need to authenticate to Firebase on that machine.

Project Management Commands

Deployment and Local Emulation

These commands let you deploy and interact with your Firebase services.

App Distribution Commands

Auth Commands

Detailed doc is here.

Realtime Database Commands

Extensions Commands

Cloud Firestore Commands

Cloud Functions Commands

Hosting Commands

Remote Config Commands

Use to update and publish a project's Firebase Remote Config template.

Authentication

General

The Firebase CLI can use one of four authentication methods listed in descending priority:

• User Token - provide an explicit long-lived Firebase user token generated from . Note that these tokens are extremely sensitive long-lived credentials and are not the right option for most cases. Consider using service account authorization instead. The token can be set in one of two ways:
  • Set the flag on any command, for example .
  • Set the environment variable.
• Local Login - run to log in to the CLI directly as yourself. The CLI will cache an authorized user credential on your machine.
• Service Account - set the environment variable to point to the path of a JSON service account key file.
• Application Default Credentials - if you use the CLI and log in with , the Firebase CLI will use them if none of the above credentials are present.

Multiple Accounts

By default sets a single global account for use on all projects. If you have multiple Google accounts which you use for Firebase projects you can authorize multiple accounts and use them on a per-project or per-command basis.

To authorize an additonal account for use with the CLI, run . You can view the list of authorized accounts with .

To set the default account for a specific Firebase project directory, run from within the directory and select the desired account. To check the default account for a directory, run and the default account for the current context will be listed first.

To set the account for a specific command invocation, use the flag with any command. For example . The specified account must have already been added to the Firebase CLI using .

Cloud Functions Emulator

The Cloud Functions emulator is exposed through commands like , and . Emulated Cloud Functions run as independent processes on your development machine which means they have their own credential discovery mechanism.

By default these processes are not able to discover credentials from . In order to provide a better development experience, when you are logged in to the CLI through we take the user credentials and construct a temporary credential that we pass into the emulator through . We only do this if you have not already set the environment variable yourself.

Using behind a proxy

The CLI supports HTTP(S) proxies via environment variables. To use a proxy, set the or value in your environment to the URL of your proxy (e.g. ).

Using with CI Systems

The Firebase CLI requires a browser to complete authentication, but is fully compatible with CI and other headless environments.

1. On a machine with a browser, install the Firebase CLI.
2. Run to log in and print out a new refresh token (the current CLI session will not be affected).
3. Store the output token in a secure but accessible way in your CI system.

There are two ways to use this token when running Firebase commands:

1. Store the token as the environment variable and it will automatically be utilized.
2. Run all commands with the flag in your CI system.

The order of precedence for token loading is flag, environment variable, active project.

On any machine with the Firebase CLI, running will immediately revoke access for the specified token.

Using as a Module

The Firebase CLI can also be used programmatically as a standard Node module. Each command is exposed as a function that takes positional arguments followed by an options object and returns a Promise.

So if we run this command at our command line:

That translates to the following in Node:

The options object must be the very last argument and any unspecified positional argument will get the default value of . The following two invocations are equivalent:

Note: when used in a limited environment like Cloud Functions, not all commands will work programatically because they require access to a local filesystem.

by Thang Minh Vu

When working on a project with multiple stages (development, staging, production), developers use the command to switch between projects. It’s very easy to run a command on the production environment instead of the development. This is very dangerous.

Note: You can always find the latest script at my GitHub repository.

Normally, developers only work on the development project. They only switch to production in case of checking or doing a hotfix. There have been a few times when I forgot to switch back to the development project. I accidentally changed the database without thinking that it could impact the actual users.

Digging into the firebase CLI, I found that it uses configstore to manage local configuration. All config is saved in a JSON file and reads easily. I created a small script which is intended to show the firebase project name on shell prompt.

How to set it up

Bash

Add the following script to the end of :

Then run or open a new terminal window:

Oh-my-zsh is a popular open source framework for Zshell. I like it because it has many beautiful terminal themes and many useful plugins.

For the final step, run or open a new terminal window:
