Run npm i in the pipelineApi directory to get the server dependencies and then npm i in the front-end directory to get the client dependencies.
Then run npm start from pipelineApi to start the server. Visit http://localhost:3001 to try the demo.
For dev mode run npm run-script start-server from pipelineApi dir and npm start from front-end dir.
Alternatively use docker compose.
Run npm run docker-build followed by npm run docker-up in the pipelineApi directory. This launches the express server on 3001 with a mongoDB image.
