# Api (Expressjs) 

This project contains the api using expressjs

## Features

- Docker Compose for MongoDB and Express.js service

- Dockerfile to create a Docker image for the app

- Azure Pipeline to build and push the image

- The pipeline will use a Helm chart template located in another repo, update the values.yaml, and then deploy

## Development server

Run `npm run dev-server` to start the api server in development mode (using nodemon).

### Dockerfile Production

```dockerfile

FROM node:21-alpine

# Copy dependency definitions

COPY package.json package-lock.json ./

# disabling ssl for npm for Dev or if you are behind proxy

RUN npm set strict-ssl false

## installing and Storing node modules on a separate layer will prevent unnecessary npm installs at each build

RUN npm i && mkdir /app && mv ./node_modules ./app

# Change directory so that our commands run inside this new directory

WORKDIR /app

# Get all the code needed to run the app

COPY . /app/

# Expose the port the app runs in

EXPOSE 3000

USER node

# Serve the app

CMD ["npm", "start"]

```

## Run Docker Compose

Run `docker-compose up -d` to start the backend express service and MongoDB.

- The backend service will now be available at localhost:3000, and the frontend can start using it.
