Guide for extending the Javascript language on VsCode for a 3rd party API

So I've started using VsCode over Atom recently and love it, the issue is I develop for software that uses its own JS API with no proper integration into anything.
I've started trying to implement my own autocomplete/intellisense structure using their pdf into VsCode to speed up my workflow, currently I'm simply using a JS file that is full of empty functions and objects with a bunch of JSDoc comments to help VsCode Intellisense identify what's what, that seems to be working fine so far but it means importing this "useless" file into every project I work on.
I looked into extending the JS language using a language server but that seems way too complex for what I need (plus it looks like I'd be building the entire Javascript language from scratch).
Does anyone have any recommendations ect?
Kind regards.
Edit
Sorry I also would like the ability for it to pass linting as right now it gets a bit funky with it.

You likely do not need an extension for that your example use case.
VS Code's intellisense for libraries is powered by .d.ts typing declaration files. The declaration files for the library you are using can either be written in your current workspace as you are currently doing, or—preferably—shipped with the library itself. Many npm modules ship their with typing definitions files, while other libraries have typing definition files provided by the community through DefinitelyTyped.
You alternatively bundle d.ts types file into as a separate npm package that you include in any project that needs them

How to implement plugins into Electron app?

I'm looking for a way to implement "Plugins" for my Electron tool.
Below is a pseudo example of how I'm thinking it would work
Supply .js/.zip/plugin file
File would contain name of plugin, and it's category (Global, Team centric, Misc)
File would contain HTML for the GUI, which get's placed in a div designated for tool space. This name would be added as an option to the necessary Select, as well as logic added to pull in the HTML to the same div
In the tool, select the plugin file:
page will load the JavaScript script, and add option to select along with logic to switch to the plugin
The hope is to automate my current process.
Currently I'm manually updating the index page to reference the new JavaScript script, and to add the option on the select
The JavaScript Script has logic in it looking at the Select, and looking to see if the option was selected
which then pulls in it's own HTML via a function within
Is there anything I can reference/utilize to make this work?

After 4+ months of working on this, I've managed to get this to work. I will try to outline my approach.
Each "plugin" or "tool" will need it's own .js file
the js file should contain an exports.html function that will return the html for the tool
the js file should contain an exports.Events function that adds all relevant event listeners
create a json file cataloging each tool, along with information needed i.e. a description, image path, .js file path, etc.
require the .js file when selected, load the html and the events
parse the json to figure out which tool to load along with needed info
all i need to do is update the json file and upload the .js file to add a new plugin.

I developed an electron app using vue as the front-end.
My idea was to develop plugins as vue plugins and publish via npm.
I used live-plugin-manager to install and uninstall plugins.
The dependencies were automatically removed by making use of a counter
The only problem I faced was how to load these installed plugins into my main app.
The workaround I found was posted as answer to my own question at How to use electron to load the vue plugins installed dynamically into a plugins folder
Hope it helps

I know I'm a little late to the party but I encountered the same problem. To solve it I have built a plugin framework for Electron called Pluggable Electron and it is available on npm.
The framework handles the lifecycle of plugins, provides as npm packages, like installation, activation, removal, etc. The plugins can then be called on at any time to exend the core app functionality.
The framework is still under development but you can find a 1st version here: pluggable-electron.
I expect it is too late for Marker but still answering here for anyone else that might have this question.

Versioning in javascript

I have multiple javascript files that are bundled and minified in one file "bundle-min.js" and is linked in one of my html page. Now I want to introduce versioning in those js files. Means when I change any of my js file, I want my bundle file version to be updated. I have found gulp-version-append but I am not sure whether it will help me or not. Also I don't want to update the reference link of bundle-min.js in my html file again and again. I want my html page to get the latest version it self somehow. Is this possible and what's the best approach? Any help?

There are plenty of modules available for this. it depends on your module loader.
Webpack
https://www.npmjs.com/package/webpack-version-file-plugin
https://www.npmjs.com/package/versioning-webpack-plugin
or you can use define plugin for this
https://webpack.js.org/plugins/define-plugin/

Editing all files & folders inside Wordpress Dashboard

I know it is possible to edit php and css file in the editor in dashboard [Appearance -> Editor].. But i was wondering why it is not possible to edit all the folders [including js files] in the editor..
I searched for this and found a plugin to make all files editable inside wordpress dashboard.. https://wordpress.org/plugins/solid-code-theme-editor/
But still is there anyway to do it by adding any javascript or shortcode or whatever??

Unfortunately there isn't a way to extend the types of files that Appearance -> Editor lets you edit (for example, adding files in subfolders, or JS files). I've tried to find a way to do this before, but - despite almost everything else being hook'able in WordPress - there is no way to hook into the file editor to change the way it works.
This could be for security reasons (having the ability to edit files like this can be a problem in the first place anyway), but in the end, the only way to add the ability to edit every file is to use an outside-of-WordPress editor, which is what the plugin you referred to does.
I usually disable the Editor entirely (by adding define('DISALLOW_FILE_EDIT',true); to wp-config.php), and use another method of editing the theme instead (usually FTP, or occasionally the file manager accessible through the web host's control panel). This way you'll have access to everything you need.

How to create a simple angular js project in webstorm

I have installed webstorm and trying to create a simple angular js program.
I have created an empty project in webstorm, then added the angular.js file in libs directory. Then when I try to write code for angular js the auto completion is not working.
Here is the screenshot of the issue.
Please help me how to create angular js programs in webstorm?
Update:
Now I have added Angular JS as a dependency by following the steps Installing AngularJS Manually in JetBrains Doc. Also removed the angular js file from my project which was present as part of my 1st image in this post.
Even then I am not able to see the auto-completion working. I have verified that the angular js plugin is enabled in my webstorm. Please let me know what could be the issue?
Update:
I have plugin for Angular JS already enabled in my webstorm, please check below image:

Not really an answer (have you saved your HTML, why not put your JS code into external files)... but why not create a project with a generator using Yeoman - http://yeoman.io/ That will give you a better app structure, build tools, package managers, unit tests... and your IDE should be better equipped for this.
This may help too: http://blog.jetbrains.com/webstorm/2014/07/how-webstorm-works-completion-for-javascript-libraries/

There is a AngularJs plugin for Webstorm. This will give you autocomletion in html files. See this tutorial how to install it:
youtube tutorial
There is even a documentation page form JetBrains which explains how to creat a AngularJs Project:
JetBrains Doc

Found in WebStorm doc
Configure AngularJS as a WebStorm JavaScript library, to let WebStorm recognize AngularJS-specific structures and provide full coding assistance:
Open the Settings dialog box, and click JavaScript Libraries.
In the Libraries area, click the Add button.
In the New Library dialog box that opens, specify the name of the library.
Click the Add button add next to the list of library files and choose Attach Files or Attach Directory on the context menu, depending of whether you need separate files or an entire folder.
Select the Angular.js or Angular.min.js, or an entire directory in the dialog box that opens. WebStorm returns to the New Library dialog box where the Name read-only field shows the name of the selected files or folder.
In the Type field, specify which version you have downloaded and are going to add.
If you added Angular.js, choose Debug. This version is helpful in the development environment, especially for debugging.
If you added the minified Angular.min.js, choose Release. This version is helpful in the production environment because the file size is significantly smaller.
