# REST API
[](https://github.com/sydrawat01/rest-api/actions/workflows/unit-test.yml) [](https://github.com/sydrawat01/rest-api/actions/workflows/packer-validate.yml) [](https://github.com/sydrawat01/rest-api/actions/workflows/packer-build.yml) [](https://github.com/sydrawat01/rest-api/actions/workflows/release.yml)
This is a basic skeleton code to create a basic REST API using NodeJS, ExpressJS and Babel.
> \[!NOTE]\
> NOTE: Please note that this is still a work in progress.
## Features
- ES7+
- NodeJS
- ExpressJS
- Winston for logging
- Basic test scripts
- Custom error handlers
- PostgreSQL and Sequelize
- Bcrypt
- Custom Amazon Machine Image using Hashicorp Packer
- Containerization using Docker
## Planned features
- AWS S3, DynamoDB and SNS Topics
- Email verification of user
- TypeScript support
## Connect to local db
```shell
psql postgres
CREATE ROLE me WITH LOGIN PASSWORD 'password';
ALTER ROLE me CREATEDB;
psql -d postgres -U me
CREATE DATABASE test;
\c test
select * from users;
```
## Docker
This is an example repository that will help you dockerize your Node+Express application using Docker.
1. Create a simple REST API with the following endpoints:
- `/` that returns OK status code (200)
- `/health` that returns OK status code(200)
2. Create a simple test that checks the health routes.
3. Create a new file named `Dockerfile` at the root of the repository.
4. Add the following configuration to the above created file:
```docker
# which node to use for your container
FROM node:alpine
# the directory where the appication will be copied to in your container
WORKDIR /usr/src/app
# copy the contents of the base(app) directory to the container WORKDIR
COPY . .
# commands to run to install dependencies
RUN npm install
# port that must be exposed to the client where the application is running in the container
EXPOSE 3000
# command to start the application in the container
CMD ["yarn", "start"]
```
5. Now, to create an image of your basic REST API:
```shell
# -t option to tag the image with a version
# if a version is not provided, the default tag is 'latest'
# the '.' option at the end is to build the current working directory
docker build -t : .
```
Example:
```shell
docker build -t api:v1 .
```
To create a docker image using another version of a `Dockerfile`, use the following command:
```shell
docker build -t : -f .
```
Example:
```shell
docker build -t api:v2 -f Dockerfile.dev .
```
6. To verify your image is build and ready:
```shell
# lists all images that docker has built or pulled from docker hub
docker images
```
7. To create and run a container:
```shell
# -ti is to run the container in an interactive terminal mode
# --name is to name your container
# -p is to expose the port from the container to the local machine where the container is running
docker run -ti --name \
-p : \
:
```
Example:
```shell
docker run -ti --name rest-api-container -p 3000:1337 api:v1
```
8. Test the API endpoints using `Postman` on `http://localhost:3000`.
9. To stop a running container:
```shell
docker container stop
```
Example:
```shell
docker container stop gpt-container
```
10. To restart a stopped container:
```shell
docker container start
```
Example:
```shell
docker container start gpt-container
```
To enter the `bash` terminal within the container:
```shell
docker exec -ti bash
```
Example:
```shell
docker exec -ti gpt-container bash
```
### Docker bind mount
The `-v` flag represents the volume in our container, where our application will be uploaded in the Docker Ubuntu image.
```shell
docker run --name \
-p : \
-v : \
:
```
Example:
```shell
docker run --name rest-api-container-2 \
-p 3000:1337 \
-v $(pwd):/usr/src/app \
api:v1
```
> NOTE: If you are on a windows computer, `$(pwd)` will not work. Instead, use `%cd%`.
### Anonymous volume
To leave the `node_modules` directory untouched in the local machine directory, and to not track it in the docker container, we use anonymous volumes.
```shell
docker run --name \
-p : \
-v : \
-v \
:
```
Example:
```shell
docker run --name rest-api-container-3
-p 3000:1337 \
-v $(pwd):/usr/src/app \
-v /usr/src/app/node_modules \
api:v1
```
Since we do not have the `:` colon to link this volume in our container to the local machine directory, this is an anonymous volume.
### SSH into a container
```shell
docker exec -ti /bin/sh
```
Example:
```shell
docker exec -ti rest-api-container-3 /bin/sh
```
### Stop and delete containers
1. Look for the container name:
```shell
docker ps
```
2. Stop the container using the container name:
```shell
docker stop
```
Example:
```shell
╰─ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
15fa4c6bbd11 api:v2 "docker-entrypoint.s…" 8 seconds ago Up 6 seconds 0.0.0.0:3000->1337/tcp rest-api
```
```shell
docker stop rest-api
```
3. To check for stopped containers:
```shell
docker ps -a
```
4. Make sure that the container is stopped, then proceed to remove that container.
```shell
docker ps;
docker rm
```
Example:
```shell
docker rm rest-api
```
### Delete docker images
To delete docker images:
1. Check the name of the image you want to delete:
```shell
docker images
```
2. Delete the image by it's name:
```shell
docker image rm :
```
Example:
```shell
# check for docker images
docker images
```
```shell
# output
╰─ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
api v3 4d74db3e5ada 7 hours ago 366MB
api v2 7bc302778f7c 7 hours ago 366MB
```
```shell
# remove the desired docker image
docker image rm api:v2
```
### Work in progress
Do not build `.env` into the docker image.
