Build the application

To illustrate the 12 factors, we start by creating a simple Node.js application as a HTTP Rest API exposing CRUD verbs on a message model.

There is a couple of prerequisite to build this application

Routes exposed

HTTP verb URI Action
GET /message list all messages
GET /message/ID get message with ID
POST /message create a new message
PUT /message/ID modify message with ID
DELETE /message/ID delete message with ID

Setup

  • Install Sails.js (it's to Node.js what RoR is to Ruby): sudo npm install sails -g
  • Create the application: sails new messageApp && cd messageApp
  • Create the message api: sails generate api message
  • Launch the application: sails lift

First tests

Create new messages

curl -XPOST http://localhost:1337/message?text=hello
curl -XPOST http://localhost:1337/message?text=hola

Get list of messages

curl http://localhost:1337/message

[
 {
   "text": "hello",
   "createdAt": "2015-11-08T13:15:15.363Z",
   "updatedAt": "2015-11-08T13:15:15.363Z",
   "id": "5638b363c5cd0825511690bd"
 },
 {
   "text": "hola",
   "createdAt": "2015-11-08T13:15:45.774Z",
   "updatedAt": "2015-11-08T13:15:45.774Z",
   "id": "5638b381c5cd0825511690be"
 }
]

Modify a message

curl -XPUT http://localhost:1337/message/5638b363c5cd0825511690bd?text=hey

Delete a message

curl -XDELETE http://localhost:1337/message/5638b381c5cd0825511690be

Get updates list of messages

curl http://localhost:1337/message

[
 {
   "text": "hey",
   "createdAt": "2015-11-08T13:15:15.363Z",
   "updatedAt": "2015-11-08T13:19:40.179Z",
   "id": "5638b363c5cd0825511690bd"
 }
