+# Docker Compose Nodejs and Postgres example
+
+## Run the System
+We can easily run the whole with only a single command:
+```bash
+docker compose up
+```
+
+Docker will pull the Postgres and Node.js images (if our machine does not have it before).
+
+The services can be run on the background with command:
+```bash
+docker compose up -d
+```
+
+## Stop the System
+Stopping all the running containers is also simple with a single command:
+```bash
+docker compose down
+```
+
+If you need to stop and remove all containers, networks, and all images used by any service in <em>docker-compose.yml</em> file, use the command:
+```bash
+docker compose down --rmi all
+```

+# 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

+```
+
+- 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;

+```
+
+- 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;

+
+- 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:
