Build a CRUD API with Golang

Overview

This code essentially sets up a basic server for managing a list of movies, allowing clients to perform CRUD operations on the movie collection through HTTP requests.

Features

  • Route by a combination of paths and HTTP methods such as GET, POST, PUT and DELETE.
  • Test web APIs with Postman.

Installation

Prerequisites

  • Go 1.20
  • gorilla/mux v1.8.X

Setup

To set up the routes which mean endpoints, you need to install the gorilla/mux. You can do this by running:

go get -u github.com/gorilla/mux

Usage

Click on the <> Code button and download the file by selecting Download ZIP. Once the download is completed, open the downloaded file in your IDE such as GoLand.

To start the application, run the following command in the terminal:

go run main.go

Navigate to http://localhost:8000/movies in your web browser. Enter an {id} number after 8000/movies/, the application will display the movie's information including id, isbn, title and director in a dictionary format.

Application's Files

  • main.go: The main file that contains the CRUD application's implementation.
  • go.mod: File contains all packages of a dependency which is required by the module.
  • go.sum: File contains cryptographic hashes of the module.
  • GO-movies.postman_collection.json: Automatically generated JSON file by Postman.
