Not a project! Just curious about the nodejs, react and mongo.

---

There are 3 components:

• frontend >>> React Single Page Application (SPA)
• backend >>> Nodejs REST API service
• MongoDB >>> Database for data.

All components are dockerized and set up a networking between them allowing to communicate with each other.

Pseudo-Schema:

To create better communication between containers you should create a network:

$ docker network create goals-app-network

To run the project:

---

1. Install mongoDB using docker container:

   $ docker run --name mongodb -v data:/data/db --rm -d --network goals-app-network mongo

After this command you should see up and running MongoDB container:

If you want an extra layer of security run the container using username and password for the mongoDB:

$ docker run --name mongodb -v data:/data/db --rm -d --network goals-app-network -e MONGO_INITDB_ROOT_USERNAME=<your_username> -e MONGO_INITDB_ROOT_PASSWORD=<your_password>

And change the connection type string inside backend/app.js to:

mongoose.connect(
  'mongodb://<your_username>:<your_password>@mongodb:27017/course-goals?authSource=admin',
  {
    useNewUrlParser: true,
    useUnifiedTopology: true,
  },
  (err) => {
    if (err) {
      console.error('FAILED TO CONNECT TO MONGODB');
      console.error(err);
    } else {
      console.log('CONNECTED TO MONGODB');
      app.listen(80);
    }
  }
);

2. Inside the backend component there is a Dockerfile. You need to build the image using the following command:

   $ cd backend

   $ docker build -t goals-backend .

   $ docker run --name goals-app-backend -v <your_full_path> -v logs:/app/logs -v /app/node_modules --rm -d -p 80:80 --network goals-app-network goals-backend

The last command uses bind mounts to make data persistence and the full command might look something like this in your environment for this repository:

$ docker run --name goals-app-backend -v /Users/username/project/backend:/app -v logs:/app/logs -v /app/node_modules --rm -d -p 80:80 --network goals-app-network goals-backend

3. Inside the frontend component there is also Dockerfile. You need to build the image using the following command:

   $ cd frontend

   $ docker build -t goals-frontend .

   $ docker run --name goals-app-frontend --rm -d -p 3000:3000 goals-frontend

Under the localhost:3000 you will be able to obtain the UI:
