noice.js

This is an object oriented library for building Progressive Web Apps. This isn't a framework, but an object hierarchy that one can either use directly or extend, to get all sorts of handy functionality, causing onlookers to exclaim "noice!".

No external dependencies, 100% bespoke vanilla javascript.

What's Here?

The ./Documentation directory contains markdown-formatted documentation

The ./examplePWA directory contains a complete example of a PWA

The ./noiceARClient directory contains an example of a BMC Remedy ARS Client written as a PWA (note: this example app is only mostly complete -- work in progress)

The ./example directory contains an example express-based server and some demos for UI components (this is an early test harness -- ymmv, but included for completeness)

The ./lib directory contains the library files:

• noiceCore.js

  core object model, everything extends a class from this file

• noiceIndexedDB.js

  provides object oriented interface to indexedDB using promises to handle the many asynchronous operations involved, a standard error object model, and a lightweight data definition language for defining indexedDB instances from configuration data.

• noiceRemedyAPI.js

  provides a simple, object oriented interface to the BMC Remedy Action Request System (ARS) REST interface

• noiceWorkerThread.js

  provides functionality useful within Worker Threads. This includes hooks for a messaging framework implemented in noiceApplicationCore.js, so while this can be used separately, it is particularly well suited for child worker threads of a PWA built from a noiceApplicationCore subclass

• noiceApplicationCore.js

  provides an object model for creating complete Progressive Web Apps (PWAs), with worker threads, a serviceWorker for offline capability, hooks for handling install-from-browser, and much more.

• noiceCoreUI.js

  provides a root-level object model for creating objects to be shown to the user on the screen (placed into the DOM tree), as well as several extension classes implementing frequently-needed UI object primitives (dialogs, ui switchers, menus, etc)

• noiceCoreUIFormElement.js

  This file contains noiceCoreUIElement (noiceCoreUI.js, above) extension classes modeling Form Elements. That is to say, more or less all of the browser-native Elements that can take user input (fields, menus, textareas etc). These can be used standalone, or within the context of a formView.

• noiceCoreUIFormElementTable.js (work in progress)

  this file contains a noiceCoreUIFormElement (noiceCoreUIFormElement.js, above) subclass implementing a table with sortable/draggable columns and rows. This is currently functional but incomplete. Documentation has not yet been written, and while basic functionallity is present, it is somewhat unreliable on mobile devices other than Apple iOS.

• formView.js (documentation in progress)

  this contains the formView class which provides a large amount of functionality for defining a form (as a collection of related formElements), with change flag hooks, asynchronous callbacks for saving, cloning, and much more. Implementation is fully functional, writing documentation is daunting due to the scale of this class, however, it all works.

The ./lib/UI directory contains classes for implementation of common UI widgets as extensions of the noiceCoreUI class:

• coreUIScannerInput.js (work in progress)

  this file contains a noiceCoreUIFormElement (noiceCoreUIFormElement.js, above) subclass implementing a character input with hooks for integration with TSL-1128 RFID Scanners. The implementation is mature and stable, the 'work in progress' status is for writing documentation.

• iFrameWidget.js (work in progress)

  this is a noiceCoreUIScreen extension class for loading external content in an embedded iFrame. This class is functional but incomplete (see documentation)

• installHelpDialog.js

  this implements a modal banner for prompting the user to install a PWA (with a "cheat code" implementation allowing a secret install bypass to run the app in browser context)

• noiceBalloonDialog.js

  a floating modal dialog, with hooks for pinning location relative to other DOM Elements, especially well suited for implementing menus.

• noicePieChart.js

  create SVG pie chart objects which can contain multiple concurrent overlaid pie charts, with animation and update hooks as well.

• noiceRadialPolygonPath.js

  create and animate SVG path objects, defined as closed polygons in radial coordinates with sprite(ish) controls like rotation, location, z-index, etc.

• recordEditorUI.js

  a noiceCoreUIScreen extension class for creating, updating, querying, etc a typical "records on a form" interface.

• startupDialog.js

  a splash screen with buttons for user interaction and many hooks for showing status (for instance spinning up indexedDB instances, fetching data from network, etc)

To-Do

• re-factor all this into ES6 Modules

Who made this?

Amy Hicox amy@hicox.com aka "SupaFuzz" on github. I sketched out basic ideas back in 2018, but mostly this was written over the past two years of COVID lockdown. No joke I restarted work on the project like 3/2020, and well ... here we are. Who would have ever thought it'd go on long enough to write this much code?

I hope you find it useful. If you've got contributions get in touch
