Use "rh [command] --help" for more information about a command.

Using the Web UI

Create an HTTP endpoint

$ rh http --web

This option will open a web UI that will display the incoming requests. Incoming requests will render live in the browser when they are received.

Create a WebSocket endpoint

$ rh ws --web

This option will open a web UI that will display the WebSocket connections and incoming messages. Connections and incoming messages will render live in the browser when they are received.

Using the CLI

Creating an HTTP endpoint

To create an http endpoint with default settings (port 8080, return status code 200):

$ rh http

Creating a WebSocket endpoint

To create a WebSocket endpoint with default settings (port 8080):

$ rh ws

Show header details

This option shows all the header details in the incoming request.

$ rh http --details

Log to file

This option will write the CLI output to the specified log file. Works with other options such as --details.

$ rh http --log rh.log

Exposing Request Hole to the internet

Sometimes we need to expose rh to the internet to test applications or webhooks from outside of our local dev env. The best way to do this is to use a tunneling service such as ngrok.

$ ngrok http 3001
$ rh http -p 3001

Running Tests and Building

It is recommended to run the JS build first so that the Go build can embed the latest web UI build.

CLI

$ go test -v ./...
$ go build

Web UI

$ cd web; yarn test
$ cd web; yarn build

For Development

$ cd web; yarn start

Visit localhost:3000
