Express training

Instructions

Use just node, express and babel-node to run your server.
Use morgan middleware to output requests.
Use body-parser middleware.

First part

• Build an express server made of below services :

1. GET /ping returns json “{ “ping”: “pong” }”

2. GET /add/<X>/<Y> returns json { result: X+Y }
   If X or Y cannot be casted to numbers, returns 500

3. Do the same with GET /add/?op1=X&op2=Y

4. The same with GET /add/?ops=[X, Y]

5. Again with POST /add body should be { values: [a,b,c,d,...] }
   returns { result: sum(values) }
   returns 500 with error message { error: message }

6. GET / returns ‘./public/index.html’.
   See ‘express.static’ middleware.

Second part

• Craft a minimalist version of a todo lists server :

Should returns 500 code in case of an error

const todos = [];
// todo = { id, label }

1. GET /api/todos returns [ ...todos ];

2. POST /api/todos

body = { todo : { label1 } }

todos.push(todo); returns todo;

3. PUT /api/todos

body = { id, label };

update existing todo returns todo.

4. DELETE /api/todos/id remove todo’s id from todos returns { id }

Let’s code ....
