Serve the web previewer without installing it

The dev server's previewer now works out of the box. Visiting the dev server address in a browser opens a Unity WebGL player running your UI, with no extra package to install.

Previously this required the optional @reactunity/previewer dependency, which shipped a ~107 MB Unity build in its npm tarball — a cost every install paid for a page many projects never opened. The build is now hosted on reactunity.github.io and fetched on first load, then cached by the browser. @reactunity/previewer is no longer used and has been dropped from peerDependencies; you can remove it from your project.

Because the build is fetched rather than bundled, the first load needs network access. To preview offline — or to preview your own Unity scene — put a previewer build in a previewer folder in your project so that previewer/index.html exists. The dev server serves that in preference to the built-in previewer, and your project's own public folder takes precedence over both.

The dev server also serves /info.html, explaining how to point Unity's DevServer property at it. That guidance used to be the page shown at /.

Fix the previewer folder override being ignored

A custom previewer placed in a previewer folder was never actually served. The dev server read paths.appPreviewer, but that key was only defined when developing react-unity-scripts in its own repository — in a published install the path resolved to undefined, so the documented override silently did nothing.
