• React frontend: Uses react query to load data from the two apis and display the result
• Node JS and Golang APIs: Both have / and /ping endpoints. / queries the Database for the current time, and /ping returns pong
• Postgres Database: An empty PostgreSQL database with no tables or data. Used to show how to set up connectivity. The API applications execute SELECT NOW() as now; to determine the current time to return.

While the whole point of this course is that you probably won't want/need to run the application locally (See: 11-development-workflow), we can do so as a starting point.

The Makefile contains the commands to start each application.

It's way more convenient to run postgres in a container as we saw in 04-using-3rd-party-containers, so we will do that.

make run-postgres will start postgres in a container and publish port 5432 from the container to your localhost.

To run the node api you will need to run npm install to install the dependencies (I used node v19.4.0 and npm v9.2.0).

After installing the dependencies, make run-api-node will run the api in development mode with nodemon for restarting the app when you make source code changes.

To run the golang api you will need to run go mod download to download and install the dependencies (I used go1.19.1)

After installing the dependencies, make run-api-golang will build and run the api.

Like api-node, you will first need to install the dependencies with npm install (again, I used node v19.4.0 and npm v9.2.0)

After installing the dependencies, make run-client-react will use vite to run the react app in development mode.
