This example shows how to authenticate a Firebase user with a custom token obtained from a backend endpoint. It demonstrates a client-side authentication flow where an Auth0 token from localStorage is sent as an Authorization header via Axios to a custom backend path, which returns a Firebase custom token. The code then uses `firebase.auth().signInWithCustomToken()` to sign in the user with that token, initializing Firebase with environment variables for its configuration. The example highlights the integration of Firebase Authentication with a custom backend service using Axios for HTTP requests.

firebaseCustomToken.js

This example demonstrates how to generate a Firebase custom authentication token by decoding an incoming JSON Web Token. The code uses the `firebase-admin` SDK to create the token and the `jwt-decode` library to extract the `sub` claim from the JWT’s Authorization header. It shows a serverless Lambda function that returns the generated custom token as a JSON response, highlighting the integration between an external JWT provider and Firebase Authentication. The rendering approach is purely computational, with no visual output.

firebaseCustomTokenServerless.yml

This example shows a serverless AWS configuration for issuing Firebase custom authentication tokens through a POST endpoint. The YAML file defines a single `auth` function using the `serverless-pseudo-parameters` plugin to reference CloudFormation resources. The function handler, `firebaseCustomTokenLambda.handler`, is triggered by an HTTP POST event at the `/auth` path. The runtime is Node.js 8.10, and the service is named `firebase-custom-token`. The file demonstrates how to wire a Firebase token-generation service into an API Gateway using the Serverless Framework, without including the actual Lambda implementation.

This example demonstrates a Firebase Cloud Function that retrieves data from a Firestore collection named `my_nice_collection`. It initializes the Firebase Admin SDK using a service account key and configures Firestore with timestamp settings. The function uses the `firebase.collection().get()` API to fetch documents, then processes the result in a promise chain, leaving room for custom data manipulation. The code highlights how serverless functions can integrate with Firestore for backend data operations.

Banking

This example shows a Firebase-backed banking transaction that processes a coin purchase in real time. It demonstrates how a Cloud Firestore transaction atomically checks a user’s coin balance, verifies item availability, deducts the total cost, updates the item quantity, and records the purchase in a separate collection. The code uses the `firebase-admin` SDK, `db.runTransaction`, and `transaction.get`, `transaction.update`, and `transaction.set` to lock and modify documents. It also relies on `functions.https.onCall` to expose the purchase operation as a callable cloud function, with error handling for insufficient funds or stock.

axios interceptors for refresh token

This example shows an Axios response interceptor that automatically handles expired access tokens by refreshing them when a request returns a 401 status. The code intercepts the failed request, checks the stored refresh token from `window.localStorage`, and posts it to an authentication endpoint at `localhost:8000/auth/refresh`. On success, it updates both the access and refresh tokens in local storage, sets the new authorization header for subsequent requests, and retries the original request. The implementation uses `axios.interceptors.response.use` with a `_retry` flag to prevent infinite loops, while relying on the browser’s local storage for token persistence and Axios’s promise-based API for asynchronous flow.

This example demonstrates how to secure Laravel AJAX requests by embedding a CSRF token in the page metadata. It shows the token being generated server-side via `{{ csrf_token() }}` and placed inside a `<meta name="csrf-token">` tag for asynchronous JavaScript calls. The code highlights that the token is unique per session and must be included in every AJAX request, though Laravel allows disabling this protection, which is not recommended. The example uses Laravel’s Blade templating syntax to inject the token into the HTML.

Batch Op

This example shows a Firebase Cloud Function that automates the onboarding process for a venue, creating related service, promotion, and venue documents in Firestore while updating the original onboard record’s status. The code uses the Firebase Admin SDK, Firestore’s batch API for atomic writes, and the `uuid/v1` module to generate unique identifiers. It processes data based on status changes, retrying up to three times on failure, and handles both draft and completed states without reprocessing.

firebase with redeux/react

This example shows how Redux acts as an intermediary between React and Firebase, managing live post data through asynchronous actions. It uses the Firebase JavaScript API to connect to a `fbredux` database, with `Posts.on('value')` listening for real-time updates and dispatching `FETCH_POSTS` actions to the Redux store. The code also demonstrates how to create and delete posts via `Firebase.push()` and `Firebase.child().remove()`, respectively, with each operation returning a thunk that receives `dispatch` as an argument. The data source is a Firebase Realtime Database, while the rendering approach relies on React’s unidirectional data flow through Redux state.
