Replace search engine and improve UX #337

davidjgoss · 2023-11-18T16:03:36Z

🤔 What's changed?

elasticlunr is removed in favour of Orama. This gets rid of bundling issues and allows us to do a production build of Ladle and deploy the preview with Netlify. It also reduces the dependency footprint (see lockfile diff).

The diff is bigger than you might expect for simply swapping out a library that does the same thing, because all Orama's interfaces (for creating indexes, and inserting, and searching) are async. This required a refactor of how and when we build the search to fit that async pattern. As such, lot of tests needed converting to be async and having assertions wrapped in await waitFor() etc.

Also, search plumbing is now extracted from the <FilteredResults/> component and done in a hook useFilteredDocuments().

Finally, applied the search query on change (with half-second debounce) so you don't have to hit enter each time - this often frustrates me as a user.

⚡️ What's your motivation

elasticlunr is unmaintained, and also published in a format that is troublesome for some module bundlers e.g. Vite that is behind Ladle. We need to replace it with something more modern, and while we're at it move logic out of components and into hooks/functions where possible.

🏷️ What kind of change is this?

🏦 Refactoring/debt/DX (improvement to code design, tooling, documentation etc. without changing behaviour)

Since this is totals for the whole test run, it's simpler and faster to interrogate cucumber data directly than go through all the Gherkin documents.

filtered can be undefined if the (async) search initialisation hasn't happened yet - in which case we just won't render anything yet in this area.
