CRUD with Golang

---

• go mod init crud-with-go
  • This will create a go module with the name as go.mod in the proejct folder
• go get "github.com/gorilla/mux"
  • We have used this gorilla/mux package to handle the routing in this application
  • We have installed the package using this command
  • We have 2 ways to install a package in command
    • go get <package_name>
    • go install <package_name>
  • But, the second one is deprecated and the first one is being used now. We can stil use the second one.
  • The only difference between them as far as I know is that get will check if the package is available, if not then it will download and then compile
  • Whereas install will directly compile, and will throw error if the package is not available
  • The get command will install the package in the GO_HOME
• It has 5 routes/endpoints for the following:
  • /movies: will provide list of all the movies(Request: GET)
  • /movies: will create a movie(Request: POST). The request body should have the following structure

    {
      "isbn": "1193453248",
      "title": "Baahubali 2",
      "director": {
        "firstname": "S.S.",
        "lastname": "Rajamouli"
      }
    }
    

  • /movies/1: will provide movie with id = 1(Request: GET)
  • /movies/1: will delete movie with id = 1(Request: DELETE)
  • /movies/1: will update movie with id = 1(Request: PUT). The request body should be same as that of the Create Request
