Edwards Alex. Let’s Go! Learn to Build Professional Web Applications With Golang

Brandberg Ltd, 2021-05-20. — 394 p. — Version 1.6.1.Go is a great language for building web applications. But teaching yourself from blog posts and the standard-library documentation can often leave you with more questions than answers.You might be wondering:
Where can I see a concrete example of a real-world web application?
How is it best to structure and organize my code?
How do I make sure I’m not making any mistakes when it comes to security?
How do I use modules to manage and version control dependencies?
And how do I effectively test my web application?
Let’s Go answers these questions for you — and a whole lot more.The book guides you through the start-to-finish build of a real-world application, so you’ll gain all the knowledge, understanding and confidence you need to create production-ready applications with Go.What You’ll Learn…
All the fundamentals — How to start a server, create handlers, send responses, route requests and serve static files.Structure and organization — How to create an idiomatic and scalable structure for your web application.Using Modules — How to use Go’s new Module functionality to manage and version control your dependencies.Managing configuration — How to use command-line flags and dependency injection to manage your application settings.Logging and Error Handling — How to implement leveled logging and centralized error handling.SQL databases — How to design a database model, set up a connection pool, and execute statements and queries.HTML templating — How to cache your templates, display dynamic data, create custom functions and handle runtime errors.Middleware — How to create your own middleware to perform common actions (like logging requests and recovering panics).RESTful routing — How to create a modern request routing structure that follows the principles of REST.Form validation — How to implement reusable and user-friendly pattern for validating forms and displaying errors.Session management — How to use and configure sessions to persist data between requests.Using HTTPS — How to correctly setup a HTTPS server and configure it for improved performance and security.Prevent common vulnerabilities — How to prevent SQL injection, CSRF, XSS, clickjacking and slow-client attacks.Authentication and authorization — How to safely encrypt user passwords and add signup, login and logout functionality.Request context — How to use Go’s context.Context to pass data between your middleware and handlers.Testing — How to create unit tests, integration tests and end-to-end tests, mock dependencies and measure test coverage.And most importantly… How to put it together in a fully-functioning application!
