Bundler usage

Typically srvx is to be imported like this.

import { serve } from "srvx";

The import above, automatically resolves the the correct entrypoint for each runtime. Node.js, Deno and Bun use ESM conditions to resolve the correct entrypoint.

If you are directly using srvx in your project without bundling or having srvx as a non-bundled dependency in package.json it should work as expected.

Bundler usage

If srvx is being bundled (by for example rollup), just during bundling the bundler also has to run the ESM resolution algorithm with a specific ESM condition. This will result srvx in the bundle to be only working with one specific runtime.

In order to avoid this, simplest way is to put srvx into the externals options.
