Go/Echo+</>Templ: Full stack Demo App with session authentication (with middleware) and centralized HTTP error handling with Golang's Echo framework, CRUD to a SQLite database (To Do List), use of Templ Template language and HTMx-powered frontend
A full stack application using Golang's Echo framework. Requests to the backend are improved in their "aesthetic" aspect with the use </>htmx (hypermedia only).
[!NOTE] This application is an clone of this repository of mine (rust-axum-askama-htmx-todoapp), but made in
Golang.
🤔 Explanation
Demo application to use session authentication (with middleware) and centralized HTTP error handling with the Echo framework.
The architecture follows a typical "onion model" where each layer doesn't know about the layer above it, and each layer is responsible for a specific thing. Although the application is extremely simple, we use this pattern to illustrate its use in more complex applications.
Layering an application in this way can simplify code structure, since the responsibility of each type is clear.
To ensure that each part of the application is initialized with its dependencies, each struct defines a constructor (the New function in this example).
[!IMPORTANT] In this application, instead of using the html/template package (native Golang templates), we use the a-h/templ library. This amazing library implements a templating language (very similar to JSX) that compiles to Go code.
Templwill allow us to write code almost identical to Go (with expressions, control flow, if/else, for loops, etc.) and have autocompletion thanks to strong typing. This means that errors appear at compile time and any calls to these templates (which are compiled as Go functions) from the handlers side will always require the correct data, minimizing errors and thus increasing the security and speed of our coding.
On the other hand, we use Golang's Echo web framework, which as stated on its website is a "High performance, extensible, minimalist Go web framework".
