The Go framework simplifies complex development tasks such as routing and database interaction. To get started, you can choose between the Gin, GORM, and Chi frameworks: Gin is lightweight and high-performance, GORM is for database interaction, and Chi allows custom routing. Create the project, install the framework and configure the database. Create a route and add a request handler to handle the request. Interact with the database, define models, and use CRUD operations to create, read, update, and delete data. Practical examples include building a blogging application using Gin and GORM.

    c.JSON(201, user)
})
