TV is an interactive debug console plugin for hapi

Lead Maintainer: Wyatt Preul

TV is a simple web page in which developers can view server logs for their requests. Optionally, they can also filter the server logs to just their requests by attaching a unique client id to each request. The server will use WebSocket to stream the logs to the web application in real-time.

Here's what it looks like in action:

Using TV in Your Application

To enable TV in a hapi application, install tv and register it. Below is an example of registering the tv plugin:

var Hapi = require('hapi');
var Tv = require('tv');

var server = new Hapi.Server();

server.register(Tv, function (err) {

    if (!err) {
        server.start();
    }
});

In applications using multiple server instances, only one server can enable the debug interface using the default port.

Options

Below are the options available to be passed into the tv plugin:

• host - the hostname, IP address, or path to UNIX domain socket the WebSocket connection is bound to. Defaults to undefined and therefore 0.0.0.0 which means any available network interface(see hapi new Server()).
• port - the port used by the WebSocket connection. Defaults to 0 and therefore an ephemeral port (see hapi new Server()).
• endpoint - the debug console request path added to the server routes. Defaults to '/debug/console'.
• queryKey - the name or the request query parameter used to mark requests being debugged. Defaults to debug.
• template - the name of the template to use for the debug console. Defaults to index.
• authenticateEndpoint - set this to true to use auth schemes for TVs main- and file delivering routes (defaults to false)

Below is an example of registering the tv plugin with some options:

var options = {endpoint: '/awesome'};

server.register({register: Tv, options: options}, function (err) {
    ...
});
