A simple TODO list app using Node.js, Express and MySQL

This example was created using Yogasaikrishna's tutorial, Simple RESTful API using Node.js, Express and MySQL, with a few tweaks.

Simple RESTful API Tutorial Summary

• Setup and configure a server using Node.js and Express in a file named app.js. Run npm init to create a package.json. Install the following dependencies: express,body-parser, and mysql, using npm install [package] --save.
• Create a database using MySQL, with the schema provided in db/schema.sql. Populate the table with sample data, as provided in db/seeds.sql.
• Create a connection pool to the database, in the file app/config/connection.js.
• Create a model for the database, in the file app/models/todo.js. Include the connection module. Create methods for get, create, update, and delete, by acquiring the connection, executing the query, and returning the results.
• Setup the routes to determine how the methods will be called, in the file app/controllers/routes.js. Include the model module. Create routes for each HTTP request of GET, POST, PUT, and DELETE, using the specific endpoint (URIs) and the corresponding method.
• Include the connection and router modules in the file app.js, and call on them before app.listen().

GET /todo and GET /todo/:id

Below is the method and request for GET /todo. This request returns everything.

this.get = function(res) {
  connection.acquire(function(err,con) {
    con.query('select * from todo_list', function(err,result) {
      con.release();
      res.send(result);
      console.log("Get successful");
    });
  });
};

app.get('/todo',function(req,res) {
  todo.get(res);
});

Result for GET /todo:

  [
    {
      "id": 1,
      "name": "Go to the post office",
      "date": "2016-07-30T21:20:05.000Z"
    },
    {
      "id": 2,
      "name": "Deposit paycheck",
      "date": "2016-07-30T21:21:29.000Z"
    },
    {
      "id": 3,
      "name": "Water plants",
      "date": "2016-07-30T21:21:29.000Z"
    },
    {
      "id": 4,
      "name": "Finish homework",
      "date": "2016-07-30T21:21:29.000Z"
    }
  ]

Below is the method and request for GET /todo/:id. This request takes in a specific ID, and returns only the data that matches with it.

this.getByID = function(id,res) {
  connection.acquire(function(err,con) {
    con.query('select * from todo_list where id = ?', id, function(err,result) {
      con.release();
      res.send(result);
      console.log("Get by ID successful");
    });
  });
};

app.get('/todo/:id',function(req,res) {
  todo.getByID(req.params.id,res);
});

Result for GET /todo/4:

[
  {
    "id": 4,
    "name": "Finish homework",
    "date": "2016-07-30T21:21:29.000Z"
  }
]
