A simple RESTful CRUD API built with Go, Gorilla Mux, and JSON.

This project demonstrates how to build a backend API in Go without a database by storing data in memory using slices. It covers all basic CRUD operations:

• Get All Movies
• Get Movie By ID
• Create Movie
• Update Movie
• Delete Movie

• Go
• Gorilla Mux
• REST API
• JSON
• Postman

Returns all available movies.

Endpoint

GET /movies

Postman Response

Returns a single movie using its ID.

Endpoint

GET /movies/{id}

Example:

GET /movies/1

Postman Response

Creates a new movie.

POST /movies

Example Request Body:

Clone the repository:

git clone https://github.com/harshbarnawa/Go-learn.git

Navigate to the project directory:

cd Go-learn/Movie-Crud/src/go-movies-crud

Install dependencies:

go mod tidy

Run the server:

go run main.go

Server starts on:

http://localhost:8000

• Handling HTTP Requests & Responses
• JSON Encoding and Decoding
• Route Parameters
• CRUD Operations
• Working with Structs and Pointers
• Testing APIs using Postman
