Previewing a release

The dev loop is not what ships: NODE_ENV is "development" and nothing is hashed. esdev preview serves the release output, which is where failures the dev loop is blind to show up — a package that hands over a different module under production, or a <link> pointing at a name hashing changed.

esdev build
esdev preview            # → http://127.0.0.1:4173
esdev preview --dir=dist --port=5000

It serves; it does not build. Missing paths that look like routes fall back to index.html, as a client-side router needs. A project whose output is a server bundle has nothing to serve — run it the way production will, under esrun.

For the rebuild-and-reload workflow, return to The dev loop.
