Built-in listeners (plugins)

Remember the generic way to enable a listener:

import { addListener } from 'storyboard';
import consoleListener from 'storyboard-listener-console';
addListener(consoleListener, options);

The following sections describe the parameters you can pass as options.

Console

Purpose: formats logs and sends them to the console (also in the browser).

Package: storyboard-listener-console

Options:

  • moduleNameLength number (default: 20): number of characters dedicated to the src field (e.g. main, storyboard, httpServer, ...)
  • colors boolean (default: true): enable/disable colors in output.
  • relativeTime boolean (default: true browser-side, false otherwise): whether full timestamps are logged, or only relative. If relativeTime is enabled, time differences lower than 10 ms are not displayed, and those higher than 1 s introduce an extra line to make the log more readable.
  • useStderr boolean (default: false): output warning and errors to stderr instead of stdout.

Parallel console

Purpose: shows parallel, top-level stories in the console, with support for resizing. It should work correctly in the following terminals:

  • OS X: Terminal.app (default terminal), iTerm, Hyper
  • Windows: cmd (default terminal), Console 2, Hyper

Package: storyboard-listener-console-parallel

Options:

  • moduleNameLength number (default: 20): number of characters dedicated to the src field (e.g. main, storyboard, httpServer, ...)
  • colors boolean (default: true): enable/disable colors in output.
  • relativeTime boolean (default: true browser-side, false otherwise): whether full timestamps are logged, or only relative. If relativeTime is enabled, time differences lower than 10 ms are not displayed, and those higher than 1 s introduce an extra line to make the log more readable.

WebSocket Server

Purpose: encapsulates logs and pushes them in real time to WebSocket clients. Used jointly with the WebSocket Client and Browser Extension, it allows remote access to server stories.

Package: storyboard-listener-ws-server

See usage hints.

Options:

  • port number (default: 8090): port for the standalone log server. Set to null to disable this server (does not affect integration with the existing application HTTP/socket.io server).
  • throttle number (default: 200): minimum interval to wait between consecutive broadcasts. Set to a falsy value for no throttling.
  • authenticate function (default: null): authentication function:
    • credentials object: login and password
    • Returns boolean|Promise of boolean: whether the user is authenticated or not
  • httpServer object: an http Server instance, which will be used to provide WebSocket services. Provide either httpServer, socketServer or none.
  • socketServer object: a socket.io Server instance, which will be used to provide WebSocket services. Provide either httpServer, socketServer or none.

WebSocket Client

Purpose: downloads server logs from the WebSocket Server, and optionally uploads client logs to the server for remote monitoring.

Package: storyboard-listener-ws-client

Options:

  • uploadClientStories boolean (default: false): enable this flag for remote access to client stories
  • throttleUpload number (default: null): minimum interval to wait between consecutive uploads. Set to a falsy value for no throttling.

Browser Extension

Purpose: relays logs to the Storyboard DevTools.

Package: storyboard-listener-browser-extension

No options available.

File

Purpose: saves logs to file.

Package: storyboard-listener-file

Options:

  • moduleNameLength number (default: 20): see Console.
  • colors boolean (default: false): whether ANSI-color escapes should be kept before saving to file.
  • filePath string (default: storyboard.log): relative path for the log file. If the file exists, new logs will be appended.

PostgreSQL Database

Purpose: saves logs to a PostgreSQL database for later retrieval, including (serialized) attachments, story hierarchy, etc.

Package: storyboard-listener-db-postgres

Options:

  • host string (default: localhost)
  • port number (default: process.env.PGPORT || 5432)
  • database string (default: process.env.PGDATABASE)
  • table string (default: logEntries)
  • user string (default: process.env.PGUSER)
  • password string (default: process.env.PGPASSWORD)
  • throttle number (default: 200): minimum interval to wait between consecutive save operations. Set to a falsy value for no throttling.
  • colors boolean (default: true): whether ANSI-color escapes should be kept before saving to the database.
