TypeScript is a superset of JavaScript, converting the entire theme to
TypeScript allows us to receive much more feedback on possible issues made in
package updates or our own typos, furthermore, it allows to transpile properly
to lower specs. This PR couldn't be done in smaller commits, a lot of work
needed to make everything *work properly*:
- A browser baseline has been set that requires minimum **Chromium 93, Firefox
92 and Safari 15** (proper visuals/operation on older browser versions is not
guaranteed)
- LightningCSS now handles minification and prefix creation for CSS.
- All hardcoded polyfills and support for previous browser baseline versions
have been removed.
- Convert codebase to TypeScript.
- Convert IIFE to ESM, handling globals with IIFE is cumbersome, ESM is the
standard for virtually any use of JS nowadays.
- Vite now builds the theme without the need for `vite-plugin-static-copy`.
- `searxng.ready` now accepts an array of conditions for the callback to be
executed.
- Replace `leaflet` with `ol` as there were some issues with proper Vite
bundling.
- Merged `head` with `main` script, as head was too small now.
- Add `assertElement` to properly check the existence of critical DOM elements.
- `searxng.on` renamed to `searxng.listen` with some handling improvements.
To avoid issue like [1], versions from now on are pinned in::
searx/static/themes/simple/package-lock.json
To test nodejs v23 or newer is needed (will be installed by nvm). To drop a
possibly existing installation::
$ make clean
Install nodejs in nvm::
$ make nvm.nodejs
INFO: install (update) NVM at searxng/.nvm
...
Now using node v23.5.0 (npm v10.9.2)
Creating default alias: default -> v23.5 (-> v23.5.0)
INFO: Node.js is installed at searxng/.nvm/versions/node/v23.5.0/bin/node
INFO: Node.js is version v23.5.0
INFO: npm is installed at searxng/.nvm/versions/node/v23.5.0/bin/npm
INFO: npm is version 10.9.2
INFO: NVM is installed at searxng/.nvm
To test npm checks and builds:
$ make static.build.commit
