In the previous tutorial, we built a simple HTTP server in Go that returned plain text responses. While that works, most modern applications communicate using JSON. Frontend applications, mobile apps, and APIs commonly exchange data in JSON format. In this tutorial, we will learn how to return JSON responses from a Go server using Go's standard library. By the end, you will understand: how JSON responses work in Go how to create structs how to encode data into JSON how to send JSON from an HTTP server Prerequisites To follow along, you should have: Go installed basic familiarity with Go syntax understanding of the net/http package You can confirm if Go is installed by running: go version Enter fullscreen mode Exit fullscreen mode Step 1 — Create the Project Create a new folder for the project: mkdir go-json-server cd go-json-server Enter fullscreen mode Exit fullscreen mode Now initialize a Go module: go mod init go-json-server Enter fullscreen mode Exit fullscreen mode This creates a go.mod file for…
