# Node.js PostgreSQL CRUD example with Express Rest APIs

Full Article with implementation:
> [Node.js PostgreSQL CRUD example with Express Rest APIs](https://www.bezkoder.com/node-express-sequelize-postgresql/)

We will build Rest Apis that can create, retrieve, update, delete and find Tutorials by title.

The following table shows overview of the Rest APIs that will be exported:

- GET `api/tutorials` get all Tutorials
- GET `api/tutorials/:id` get Tutorial by id
- POST `api/tutorials` add new Tutorial
- PUT `api/tutorials/:id` update Tutorial by id
- DELETE `api/tutorials/:id` remove Tutorial by id
- DELETE `api/tutorials` remove all Tutorials
- GET `api/tutorials/published` find all published Tutorials
- GET `api/tutorials?title=[kw]` find all Tutorials which title contains 'kw'

Front-end that works well with this Back-end

## Demo Video
This is our Node.js PostgreSQL CRUD example using Express & Sequelize application demo, test Rest Apis with Postman.

[![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")

### Test the APIs
Run our Node.js application with command: `node server.js`.

Using Postman, we're gonna test all the Apis above.

- Create a new Tutorial using `POST /tutorials` Api

![node-js-postgresql-crud-example-create](https://dev-to-uploads.s3.amazonaws.com/i/hqvz8ra9p21z927iwzph.png)

After creating some new Tutorials, you can check PostgreSQL table:
```testdb=# select * from tutorials;
id | title | description | published | createdAt | updatedAt
----+-------------+-------------------+-----------+----------------------------+----------------------------
1 | Node Tut #1 | Tut#1 Description | f | 2020-01-29 10:42:57.121+07 | 2020-01-29 10:42:57.121+07
2 | Node Tut #2 | Tut#2 Description | f | 2020-01-29 10:43:05.131+07 | 2020-01-29 10:43:05.131+07
3 | Node Tut #3 | Tut#3 Description | f | 2020-01-29 10:43:48.028+07 | 2020-01-29 10:43:48.028+07
4 | Js Tut #4 | Tut#4 Desc | f | 2020-01-29 10:45:40.016+07 | 2020-01-29 10:45:40.016+07
5 | Js Tut #5 | Tut#5 Desc | f | 2020-01-29 10:45:44.289+07 | 2020-01-29 10:45:44.289+07
```

- Retrieve all Tutorials using `GET /tutorials` Api

![node-js-postgresql-crud-example-retrieve-all](https://dev-to-uploads.s3.amazonaws.com/i/m9razjm1njgww58er3as.png)

- Retrieve a single Tutorial by id using `GET /tutorials/:id` Api

![node-js-postgresql-crud-example-retrieve-one](https://dev-to-uploads.s3.amazonaws.com/i/0kuojvc596i5u423od2b.png)

- Update a Tutorial using `PUT /tutorials/:id` Api

![node-js-postgresql-crud-example-update](https://dev-to-uploads.s3.amazonaws.com/i/3buqfz0by0lu2z4kf3uq.png)

Check `tutorials` table after some rows were updated:
```testdb=# select * from tutorials;
id | title | description | published | createdAt | updatedAt
----+----------------+-------------------+-----------+----------------------------+----------------------------
1 | Node Tut #1 | Tut#1 Description | f | 2020-01-29 10:42:57.121+07 | 2020-01-29 10:42:57.121+07
3 | Node Tut #3 | Tut#3 Description | f | 2020-01-29 10:43:48.028+07 | 2020-01-29 10:43:48.028+07
2 | Node Js Tut #2 | Tut#2 Description | t | 2020-01-29 10:43:05.131+07 | 2020-01-29 10:51:55.235+07
4 | Js Tut #4 | Tut#4 Desc | t | 2020-01-29 10:45:40.016+07 | 2020-01-29 10:54:17.468+07
5 | Js Tut #5 | Tut#5 Desc | t | 2020-01-29 10:45:44.289+07 | 2020-01-29 10:54:20.544+07
```

- Find all Tutorials which title contains 'js': `GET /tutorials?title=js`

![node-js-postgresql-crud-example-search](https://dev-to-uploads.s3.amazonaws.com/i/u2hbmz5r35o7uo09y3z5.png)

- Find all published Tutorials using `GET /tutorials/published` Api

![node-js-postgresql-crud-example-search-status](https://dev-to-uploads.s3.amazonaws.com/i/dbo753wfqibt0b93d82d.png)

- Delete a Tutorial using `DELETE /tutorials/:id` Api

![node-js-postgresql-crud-example-delete-one](https://dev-to-uploads.s3.amazonaws.com/i/pyos3wq4tchb8ixuyj1c.png)

Tutorial with id=4 was removed from `tutorials` table:
```testdb=# select * from tutorials;
id | title | description | published | createdAt | updatedAt
----+----------------+-------------------+-----------+----------------------------+----------------------------
1 | Node Tut #1 | Tut#1 Description | f | 2020-01-29 10:42:57.121+07 | 2020-01-29 10:42:57.121+07
3 | Node Tut #3 | Tut#3 Description | f | 2020-01-29 10:43:48.028+07 | 2020-01-29 10:43:48.028+07
2 | Node Js Tut #2 | Tut#2 Description | t | 2020-01-29 10:43:05.131+07 | 2020-01-29 10:51:55.235+07
5 | Js Tut #5 | Tut#5 Desc | t | 2020-01-29 10:45:44.289+07 | 2020-01-29 10:54:20.544+07
```

- Delete all Tutorials using `DELETE /tutorials` Api

![node-js-postgresql-crud-example-delete-all](https://dev-to-uploads.s3.amazonaws.com/i/ga42747jorssl20ywyug.png)

Now there are no rows in `tutorials` table:
```testdb=# select * from tutorials;
id | title | description | published | createdAt | updatedAt
----+-------+-------------+-----------+-----------+-----------
```
