This is a Todo List API with CRUD functionality implemented using Go and MongoDB. The API provides the following features:

• Login: Users can authenticate and obtain a JWT token to access the API.
• Todo List Operations: Users can create, read, update, and delete Todo items.

Before getting started with the API, make sure you have the following software and services:

• Go Programming Language: https://golang.org/doc/install
• MongoDB Database: https://www.mongodb.com/

1. Download or clone the source code of this project.

git clone https://github.com/ushio0107/todo-api.git

2. Create a new database in MongoDB.
3. Edit the config.go file and update the database connection URL with your MongoDB configuration.

const mongoDBUrl = "mongodb://localhost:27017"
const mongoDBName = "your_database_name"

4. Build and run the API.

go build
./todo-api

5. The API will be running locally at http://localhost:3000/v1.

Before using the API, obtain a JWT token. Send a POST request to the /login endpoint with the correct username and password.

POST /login
Content-Type: application/json

{
  "username": "admin",
  "password": "password"
}

Upon successful login, you will receive a JWT token.

Send a POST request to the /v1/todos endpoint with the details of the Todo item.

POST /v1/todos
Authorization: Bearer <token>
Content-Type: application/json

{
  "task": "Complete the project",
  "completed": false
}

Send a GET request to the /v1/todos endpoint to retrieve all Todo items.

GET /v1/todos
Authorization: Bearer <token>

Send a GET request to the /v1/todos/{id} endpoint to retrieve a specific Todo item by its ID.

GET /v1/todos/{id}

Send a PUT request to the /v1/todos/{id} endpoint to update a specific Todo item by its ID.

PUT /v1/todos/{id}
Authorization: Bearer <token>
Content-Type: application/json

{
  "task": "Update the project",
  "completed": true
}

Send a DELETE request to the /v1/todos/{id} endpoint to delete a specific Todo item by its ID.
