Describe your PR

There is a scripting tool called zx that is a hybrid between bash and node scripting. It has a lot of dev experience and productivity of gluegun.

To play around with it, I decided to implement some of the existing generators in ignite. This was relatively simple to do. And with this extension, you can even get syntax highlighting with the js strings.

This may be a nice alternative API for generators so that ignite users can update these scripts as a project grows.

Initially, I thought about creating an alternative typescript generator API that I create a proof of concept of. But the nice thing about using zx is that it would pretty much remove any maintenance cost with generators from ignite. Additionally, these scripts are portable, so they can dropped into existing projects.

I will leave this PR here for discussion and an artifact of that exploration

Instead of using template literals for file strings, I decided to go with doing a regex replace.

This was for a few reasons:

• using template literal syntax breaks syntax highlighting from this extension
• I find it's hard to read

A trade off is that it's not immediately obvious which strings are variables in a template string. But I still find it to be pretty readable, and one can always use Ctrl+F to see what is getting find and replaced

zx can be used with typescript, but it requires some specific package.json and tsconfig settings that I don't see on many projects. However, the existing globals have nice type defs already. And we can use jsdoc to create types otherwise. Another approach here may be to add .d.ts files and import them using jsdoc

This PR does not have the splash-screen or app-icon generator implemented, but I wanted to get some feedback about the reaction of this approach before implementing more sophisticated scripts like that

[joshuayoes]

Other interesting zx features of note:

• You can write these scripts as markdown files.
• You can execute remote scripts from a URL. So potentially cookbook recipes could be executed from the website
• Being able to import and export js modules means users can write their own "tools" as they need to in ignite projects.

This is very interesting, I'll need to take a deeper look at this. But at first glance, this seems like a more mature solution.

The idea of this PR is that generators are something that should be co-located in each project and should be able to evolve with it. I have found many projects with generators from frameworks eventually abandoning them because a team adopted a style that was not compatible with it.
