A skeleton for un-bundled react projects.
this command will do an npm install for you
npm run vendornpm run buildnpm run watchnpm run serveNo bundler, pure ES2015 modules loaded directly into the browser. It uses es-module-shims for import map support (not yet implemented in any browsers) but otherwise doesn't use any special loaders, bundlers, file servers, etc. Hosting is done via a static file server, you could use any static file server you wanted but I chose http-server because it is small and simple.
The one caveat with this project is the vendoring of dependencies. If you add a runtime dependency, you will need to manually add it to the array at the top of build/vendor.ts. Just create an entry in the array specifying the dependency package name, the path within the package that should be copied (whole folder will be vendored, usually this is a dist or out folder), and the relative path to the index file and then (from the root directory) run npm run vendor. This will generate the runtime import map and embed it into your index.html file so the browser can turn import { ... } from 'my-package' into import { ... } from './vendor/my-package/index.js'.
