Build and Run App Locally

Pre-dependencies

Program	Download link	Note
Node.js	https://nodejs.org/en/download	Also installs npm package manager
Git	https://git-scm.com/downloads
(Optional) pnpm	https://pnpm.io/installation	This is a different package manager used for reduced disk space when installing below packages. This is optional, the builtin npm will work too with below commands, Just replace pnpm with npm

Dependencies

Step	Terminal commands	Notes
clone the repository or download it as ZIP file	git clone https://github.com/new-AF/timestamp-microservice.git
enter the directory of the now local repository	cd timestamp-microservice
install the dependencies	pnpm install
Run the backend server	pnpm exec server/server.js	For npm run npx nodemon server/server.js most API calls like http://localhost:3000/api/1451001600000 will work except the root path http://localhost:3000 http://localhost:3000/ these will not run the React App because they look for the index.html in the missing directory dist that is created and updated by running pnpm run build each time you edit the React App to run the most recent version. To avoid running the build command each time, access the React App from the frontend server below.
Run the frontend server and the React App	pnpm run dev	For npm run npm run dev access the server on the show port number like so http://localhost:5173/
