tv

TV is an interactive debug console plugin for hapi

Lead Maintainer: Oscar A. Funes Martinez

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:

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

const server = new Hapi.Server();

server.register(Tv, (err) => {

    if (err) {
        throw 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 public hostname or IP address. Used only to set server.info.host and server.info.uri. Deaults to hostname and if not available to localhost(see hapi new Server()).
• address - the hostname of IP address the WebSocket connection will bind to. Defaults to host if present otherwise 0.0.0.0(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:

const Hapi = require('hapi');
const Tv = require('tv');
const options = { endpoint: '/awesome' };

const server = new Hapi.Server();

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