Fork, then download or clone the repo.

git clone<your-user-name>/mern-crud.git

Make sure MongoDB service is running.

The config folder contains a file named db.js. Before running locally, change the value of db as seen in the code below.

module.exports = {
  db: 'mongodb://localhost/mern-crud'

For the back-end, install the dependencies once via the terminal.

npm install

Run the main server. It listens on port 3000.

CORS=1 node server

View it on the browser.

If you want to configure the front-end, go to react-src folder via the terminal.

cd react-src

Install the dependencies required by React once.

npm install

Run the development server for React. It listens on port 4200.

REACT_APP_API_URL=http://localhost:3000 npm start

To make a production build, simply run on react-src folder via the terminal.

npm run build

It re-creates a folder named public on the root directory. This is where the production-ready front-end of the web application resides.


docker-compose up
