Summary

The video provides a comprehensive overview of setting up and utilizing the Axum web framework. It covers topics ranging from basic server setup to advanced features like middleware, URL parameter handling, static file serving, and implementing cookies for authentication. Additionally, the video dives into best practices for error handling, logging, and structuring log lines for efficient querying and analysis, making it a valuable resource for developers looking to build robust web applications with Axum.


Introduction to Axum Web Framework

Introduction to Axum web framework and the three main sections covered in the video: beginner, intermediate, and advanced sections.

Setting Up the Server with Axum

Setting up the server with Axum by adding the Axum package, creating the first router, setting up routes for hello, starting the server, and testing the hello world response in the browser.

Implementing Custom Middleware and Request Logging

Implementing custom middleware, custom extractor, and request logging in Axum web framework. Testing the server with cargo run and viewing the response in the browser.

Creating a Quick Development Environment

Creating a quick development environment with client and backend terminals, using Cargo test for testing HTTP client, and setting up cargo watch for automatic server and client updates.

Handling URL Parameters with Extractors

Handling URL parameters using extractors in Axum, creating structs for URL parameters, extracting query parameters, and passing parameters in the URL.

Passing Parameters in Path URL

Building a handler for URLs with parameters in the path, implementing a handler function with path extractor, mapping the handler in the router, and testing the URL with parameters.

Implementing Static Routing and File Serving

Implementing static routing for serving files in Axum, using Tower as a service library, nesting paths for static files, serving files locally, and handling fallback routes.

Adding Cookies to Login API

Adding cookies to the login API in Axum, setting cookies in the response, handling cookies in the client, and testing the login API functionality with cookies.

Creating a Model Layer with Mock Store

Creating a model layer with a mock store, defining payload types for the CRUD operations, implementing CRUD methods in the model controller, and setting up routes for CRUD operations.

Starting Handlers

Explains how to initialize and set up handlers for various requests, including creating, updating, and deleting tickets.

Passing Multiple States

Discusses a method to efficiently pass multiple states using a structured approach.

Initializing Model Controller

Covers initializing the model controller and merging REST API routes.

Creating and Deleting Tickets

Demonstrates the process of creating and deleting tickets through API calls.

Implementing Middleware for Authorization

Shows how to implement middleware for authentication to restrict access to logged-in users.

Creating Custom Middleware

Explains the creation of custom middleware for authentication and user access control.

Implementing Custom Extractors

Discusses creating custom extractors for handling user IDs and context within the application.

Error Handling and Status Codes

Explains how to handle errors and map them to appropriate status codes for better server responses.

CTC Resolver and Request Flow

Discusses the CTX resolver, request flow, server log line with UUID, and handling client errors effectively.

Building Server Log Line

Explains the difference between request log lines and tracing, setting up logging for CloudWatch, and creating a structured log line for flexible querying and analysis.

Creating Log Mode

Establishes a log mode for logging purposes, imports necessary tools, focuses on flattening log attributes for efficient querying, and discusses log request function implementation.

Implementing Log Request Function

Implements the log request function, captures essential information for the request log line, handles error types, serialization, and mapping error data.

Building Request Log Line

Builds the request log line with essential attributes like UID, timestamp, request information, user ID, error types, and prepares for sending logs to a cloud watch service.

Handling Service Errors

Discusses handling client and service errors, serializing error data, structuring error outputs to JSON, and integrating error data in the request log line.

Capturing Information in Response Mapper

Ensures capturing all necessary information in the response mapper, extracting client errors, and calling the log request function with complete data for the request log line.

Optimizing Unzipping for Client Errors

Optimizes unzipping to extract client errors efficiently, managing options of client errors, and tailoring the output for better error handling and logging.

Printing Request Log Line

Prints the request log line as a JSON line, emphasizing the future integration with cloud watch services for efficient log management and monitoring.

Finalizing Request Log Line

Finalizes the request log line with UID, timestamp, request information, user ID, error types, and prepares for logging to cloud watch service for production.

Ensuring Complete Log Information

Ensures complete log information capture in the response mapper, including CTX information, URI, methods, client errors, and log request function calls for comprehensive logging.

Handling Client Errors

Effectively handles client errors by extracting options of client errors, utilizing unzip function for error handling, and ensuring accurate client error information in the log.
