Add a simple js-only plugin template

[jmcook1186]

What
Add a new repository to the gSF organmization Githiub called if-js-plugin-template and prepopulate it with the code for a minimal plugin that can easily be loaded into if.

Why

As a plugin builder I want to rapidly prototype plugins using javascript, rather than typescript. This will help me to rapidly prototype and create plugins for demos and proofs-of-concept.

There are several times when we have wanted to quickly create new plugins for demos, but conforming to the relatively strict standards imposed in the typescript template has slowed things down. We could also provide a javascript-only simplified template for rapid plugin development.

Acceptance criteria

• code for a minimal plugin is available in new if-js-plugin-template repository

  • includes a index.js, package.json and README
  • includes an example manifest

• README includes explanation of how to install demo plugin and run from if using the example manifest provided

  • includes step by step instructions for using npm link to create local package for plugin
    GIVEN a user clones the new if-js-plugin-template repository
    WHEN follow the instructions int he template readme
    THEN they can execute the template plugin code in their locally installed if

SoW

• create repository
• add plugin code
• add example manifest
• add README with instructions

@jmcook1186 let's have the javascript version in a separate repository

@jmcook1186 @manushak and @narekhovhannisyan to have a disussion before implementing this in case there is opportunity to create a single repo for Js and typescript templates

@jmcook1186 please create a repo for this template to unblock @manushak 🙏
