To create a build-less web frontend that runs directly in the browser, you can use ES Modules with import maps for CDN dependencies. This approach eliminates bundlers and build steps entirely, allowing static pages and SPAs to execute natively while handling cache-busting and performance optimizations automatically.

A build-less ESM frontend uses native ES Modules for direct browser execution without requiring bundlers or build tools. You should use this approach for creating prototypes, static webpages, or single-page applications when you want to avoid the overhead of build tools like Vite or Webpack.

Yes, you can build a Preact SPA without configuring bundlers by utilizing native ES Modules and import maps to load dependencies directly from a CDN. This build-less development workflow streamlines the process by eliminating build steps entirely while still supporting modern JavaScript capabilities.

You handle CDN imports and cache-busting for static pages by configuring native ES Module import maps within your HTML. This build-less browser execution method manages external dependencies and performance optimizations directly without relying on a bundler to inject or hash your module URLs.

You should avoid a build-less ESM approach if your web application requires complex transformations, legacy browser support, or heavy module bundling that native browser execution cannot handle. This method is designed for prototypes and static pages without the overhead of build tools like Vite or Webpack.
