> [Node.js CRUD Rest APIs with Express, Sequelize & PostgreSQL example](https://bezkoder.com/node-express-sequelize-postgresql/)
55
6+
We will build Rest Apis that can create, retrieve, update, delete and find Tutorials by title.
7+
8+
The following table shows overview of the Rest APIs that will be exported:
9+
10+
- GET `api/tutorials` get all Tutorials
11+
- GET `api/tutorials/:id` get Tutorial by id
12+
- POST `api/tutorials` add new Tutorial
13+
- PUT `api/tutorials/:id` update Tutorial by id
14+
- DELETE `api/tutorials/:id` remove Tutorial by id
15+
- DELETE `api/tutorials` remove all Tutorials
16+
- GET `api/tutorials/published` find all published Tutorials
17+
- GET `api/tutorials?title=[kw]` find all Tutorials which title contains 'kw'
18+

## Demo Video
29+
This is our Node.js PostgreSQL CRUD example using Express & Sequelize application demo, test Rest Apis with Postman.
30+
31+
[![Node.js PostgreSQL CRUD example Github](http://img.youtube.com/vi/x1pZHN_sjGk/0.jpg)](http://www.youtube.com/watch?v=x1pZHN_sjGk "Node.js PostgreSQL CRUD example Github")
32+
33+
### Test the APIs
34+
Run our Node.js application with command: `node server.js`.
35+
36+
Using Postman, we're gonna test all the Apis above.
37+
38+
- Create a new Tutorial using `POST /tutorials` Api
39+
40+
![node-js-postgresql-crud-example-create](https://dev-to-uploads.s3.amazonaws.com/i/hqvz8ra9p21z927iwzph.png)
41+
42+
After creating some new Tutorials, you can check PostgreSQL table:
43+
```testdb=# select * from tutorials;
44+
id | title | description | published | createdAt | updatedAt
