## Running the Application

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.

### Postgres

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.

### api-node

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.

### api-golang 

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.

### client-react

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.
