unpkg CDN as a fallback?

Hi @lukejacksonn, first off, thank you so much for putting this together.

While using servor for my prototype work, I wanted an ability to use servor without even npm installing my dependencies 🎉 🎉

One way I was thinking to solve this, is by adding a check in servor to see if we are serving a JS file. If a JS file is not available locally, we rewrite the URL to UNPKG CDN URL.

For Example:

Let’s say I have code like this in say index.js:

import { patch, h } from 'superfine';
import store from '@vanillajs/store';

servor would rewrite this to something like this (when node_modules is not available):

import { patch, h } from 'https://unpkg.com/superfine@6.0.1?type=module';
import store from 'https://unpkg.com/@vanillajs/store@0.1.7?type=module';

To take it a step further, if I do not have package.json, we simply rewrite the URL to something like this:

import { patch, h } from 'https://unpkg.com/superfine?type=module';
import store from 'https://unpkg.com/@vanillajs/store?type=module';

This idea has been explored before with owc-dev-server and works quite well using express-transform-bare-module-specifiers

However, I would like a no-dependency solution for this to be available in servor

thoughts/concerns?

Awesome, I’ll try to get to this soon. We will need to explore if this can bring any unforeseen hurdles if we make it a default. Alternative would be to have a flag to disable this behavior.

Hey @osdevisnot if you figure this out then please open a PR and reference this issue. I’m very interested in what it might look like but am doing a tidy up here so am going to close for now!
