CRUD application using Sails JS and MongoDB Part-I

Today we will make a Books app

Libraries/Modules used:

Mongoose

Sails JS

Please make sure you have node js and sails js installed [Installation]

Initialise the sails project using

sails new books-app

Choose empty project in the console(2)

cd books-app

lets now quickly install all the dependencies

npm i mongodb mongoose

Go inside config/models.js uncomment migrate: ‘alter’ and replace alter with safe. Alter will drop the schema everytime we restart the server which we do not want.

migrate: ‘safe’,

Create a new file called mongoose.js inside config folder

touch config/mongoose.js

We will create our db connection using from this file, now paste the following code in mongoose.js

Generate a file called author inside api/models/author.js

sails generate model author

Inside api/models/author.js remove the existing code and paste the following

Lets now create controllers for author, we start with create and we will here create stand-alone actions [Know more on stand-alone actions!]

sails generate action author/create — no-actions2

We used — no-actions2 flag to use the traditional node js functions rather than sails functions with req and res.

Paste the following code inside you api/controller/author/create.js

Go to config/routes.js and add a route for the api we just created, below the default view route

‘/author/create’: {action: ‘author/create’},

Now its time to test our API, go to postman and create a post request at

localhost:1337/author/create

Fill body as raw json

When you click send you should the response like this

Now go to your mongodb tool, I am using compass and check if the data has been stored or not

Since this article is getting long we will create the rest of end-points in the part-II.
