jwt VS Gin

To add JWT authentication to our ToDo application, we'll be using the Golang-jwt library. The golang-jwt package simplifies the implementation of JWTs in Go applications, offering a suite of convenient functions that abstract away the complexities associated with token creation, verification, and management.

To create a secure Role-based authentication scheme, we need to generate a unique token when the user authenticates. This is then used to track their assigned role as they consume the availed resources. In this project we are going to use the jwt-go package to generate a JWT token that will encapsulate the user details, assigned role and permissions.

Yes. Currently maintained version is here: https://github.com/golang-jwt/jwt

Libraries used bcrypt: https://pkg.go.dev/golang.org/x/crypto/bcrypt golang-jwt: https://github.com/golang-jwt/jwt Gin (Http framework): https://github.com/gin-gonic/gin

We will implement Golang JWT authentication using a go-jwt package.

Authorization jwt

At least template-wise, I've developed pongo2 mimicking Django's template engine which I use myself for various projects. For the rest I usually stick with the standard library (net/http), golang-jwt, the Gorilla toolkit (note that it's been archived recently) and some software architecture patterns for middlewares, database abstraction, etc.

Either way, you will need to validate the signature of the JWT. You can do this with the public key and a library such as https://github.com/golang-jwt/jwt.

Now let’s define the functions that will be called whenever a request hits our API. All the functions will be referencing the context provided by the Gin web framework. Paste the following code below the sample slice we just added to api.go:

We will be using Gorilla Mux. As per their last update, they have a new group of maintainers, and their repos have shown activity to confirm that. The tutorial can be easily replicated in any other framework or library as well. So, while we will be using Gorilla Mux, you can try to replicate it in Gin or Fiber as well.

Now, let's dive into the fun part – creating our basic ToDo application using the powerful Gin framework. This section will walk you through the steps, breaking down the code into manageable snippets.

Thanks to the AWS Lambda Web Adapter, the application built as a (good old) REST/HTTP API using a familiar library (in this case, Gin.

Excellent Performance: Sponge is built on the gin framework, providing outstanding performance for web service development.

In this blog, we will delve into the fascinating realm of handling images in a Golang application, leveraging the power of the Gin framework for RESTful API development, MongoDB as a robust NoSQL database, and the mongo-driver library for seamless interaction with MongoDB. To store images efficiently, we'll explore the intricacies of GridFS, a specification within MongoDB for storing large files as separate chunks.

It uses Gin as the HTTP framework and PostgreSQL as the database with pgx as the driver and Squirrel as the query builder. It also utilizes Redis as the caching layer with go-redis as the client.

I have created an application with Go in Gin-Gonic. In my frontend (Nuxt3/TypeScript) I always get a CORS error:

We use Gin web framework https://gin-gonic.com for the routing, Gin provides a balance between performance, ease of use and extensibility making it a preferred choice for building and running web applications in Go.
