shiny: Web Application Framework for R

Development Rules

Put Imports at top
Put Exports at bottom
File / Folder structure
Lean towards using more many files / folder vs larger files
Nest folders inside larger ideas
Each folder should generally have an **/index.ts to export most everything for the folder
- Exception: ./src/window folder. Must call methods directly.
Any window.*** calls are done in ./src/window folder only.
Add exported values / function if necessary.
This helps keep each file self contained. Trying not to have random inputs from anywhere
jQuery
Always import ./src/jquery instead of "jquery"
- Exeption: Test files. There, you can import "jquery" directly as the browser is not available to already have jQuery loaded.
Prevents from installing local jquery in addition to global jquery
- WAY to many packages exist on the assumption that jquery is available at run time. Therefore, it can not be removed globally. :-(
Anything that needs to be initialized on start must exist in the ./src/initialize folder.
No file should produce any side effects.
To capture initializations, export a setFoo(foo_) method that updates a locally defined foo variable.

√ Move everything into a single ts file. This will allow for the functions to find themselves
√ Except the utils.js already converted
√ es6 shiny.js
√ Pass in version using esbuild
√ Move all shiny files in order to main.ts
√ validate polyfills are working by finding them in the code
√ Produce minified shiny js
√ Disable $ from being found without an import
√ Using a patch with yarn v2
√ Document ./package.json scripts
√ Verify that babel is configurable
√ Use targeting browsers
√ Verify it works on phantomjs / shinytest
√ Set up initial jest tests
√ Use a global shim to avoid importing jquery directly, but make testing easy to test
Update the /tools/update*.R scripts to produce a version and install node dependencies
√ jquery
√ ion range slider
√ selectize
√ strftime
√ bootstrap date picker
font awesome?
bootstrap accessibility plugin?

Convert registered bindings
√ Input bindings
√ Output bindings
Add default value to subscribe(callback) callback function of false. B/c if the value was not provided, it was not truthy, therefore equivalent to false.
√ radio
√ checkboxgroup
√ daterange
√ actionbutton
√ bootstraptabinput
√ snake_case to camelCase conversions.
√ globally import strftime from window.strftime
Remove evt from jQuery.on callbacks where evt was not used.
√ checkbox.subscribe
√ checkboxgroup.subscribe
√ radio.subscribe
√ slider.subscribe
√ date.subscribe
√ selectInput.subscribe
√ actionButton.subscribe
√ bootstraptabinput.subscribe
Convert usage of +x to Number(x)
https://stackoverflow.com/a/15872631/591574
√ slider.getValue()
√ number.getValue()
√ Adjust tabinput.ts setValue() to return either false | void, not false | true.
What matters is that false is returned, or nothing is returned. Replaced return true; with return;
Questions
Why does receiveMessage(data) sometimes have a label?
Should we have a update datatables script?

Use yarn PnP
See ./patch/yarn_pnp.patch
Use esbuild
Known problems:
- @yarnpkg/esbuild-plugin-pnp@0.0.1 gives full file paths, not relative file paths
- @testing-library/jest-dom/extend-expect can not be found.
