# go-app

A simple app framework for bootstrapping logging, otel, and servers from config and environment

## Usage

- Use the helper function to load config file (if given with -config) and apply
configuration through environment. This will prepare your app config and logging.

- Load up HTTP routes and health checks.

- Start the app.

- Wait for it to be done and do any extra cleanup.

Here is a reference main.go

```go
package main

import (
	"context"
	"os"
	"os/signal"

	"gitea.libretechconsulting.com/rmcguire/go-app/pkg/app"
	"golang.org/x/sys/unix"
)

func main() {
	ctx, cncl := signal.NotifyContext(context.Background(), os.Kill, unix.SIGTERM)
	defer cncl()

	ctx = app.MustSetupConfigAndLogging(ctx)

	awApp := app.App{
		AppContext: ctx,
		HTTP: &app.AppHTTP{
            // Load up your HTTP methods here
			Funcs: []srv.HTTPFunc{
				{
					Path: "/test",
					HandlerFunc: func(w http.ResponseWriter, r *http.Request) {
						w.WriteHeader(http.StatusNotImplemented)
						w.Write([]byte("unimplemented test method"))
					},
				},
			},
            // Load up health checks here
			HealthChecks: []srv.HealthCheckFunc{
				func(ctx context.Context) error {
					return errors.New("health check unimplemented")
				},
			},
		},
	}

	awApp.MustRun()
	<-awApp.Done()
}
```
