Basic Book REST API

→ This is a simple RESTful API for managing a collection of books. It is built using Go and the Chi router, with PostgreSQL as the database.

Prerequisites

→ Before running this application, make sure you have the following installed:

• Go (https://golang.org/)

• PostgreSQL (https://www.postgresql.org/)

• Install Postgresql driver:

    go get github.com/lib/pq

  or

  go get github.com/jmoiron/sqlx

• Install go-chi package:

     go get -u github.com/go-chi/chi/v5

Database Configuration

→ The application connects to a PostgreSQL database. Make sure to configure the database connection in the init function of the main package. Update the connection string in the following line: go

    db, err = sqlx.Open("postgres", "user=postgres password=Your_postgres_password host=Your_local_host dbname=Your_databse_name sslmode=disable")

API Endpoints

• POST /createbooks: Create a new book.
• DELETE /deletebooksbyid/{id}: Delete a book by ID.
• PUT /updatebooksbyid/{id}: Update a book by ID.
