fix: implement instant real-time and server-side search filtering on storefront by ClausValcaTD · Pull Request #17 · M5Devs/OpenROM-Store

ClausValcaTD · 2026-11-05T22:48:03Z

What was actually broken

Instant client-side filtering on the homepage already worked. I checked before
changing anything: typing nkit narrowed the grid to the two NKit cards, typing
nonsense hid every card and revealed the ROMeo empty state — on the built worker
and on production. The inline scripts prod and local serve are byte-identical.

The real defect is that the search box is in the shared Navbar, while its only
handler was in index.astro:

                     /        /plugin/*   /publisher/*   /dashboard
search box           ✓          ✓            ✓              ✓      (Navbar, every page)
input handler        ✓          ✗            ✗              ✗      (index.astro only)
                     ──────────────────────────────────────────
typing does something ✓        nothing      nothing        nothing

So on every page except the catalog the box was inert — type and nothing happens.
There was also no <form>, so Enter never submitted, no clear (X) control, and
?q= was only ever handled client-side.

The fix

Navbar.astro — the box is now a real search form that works from anywhere:

<form role="search" method="get" action="/">
  <input id="search" name="q" value={searchValue} … />
  <button data-search-clear …>✕</button>
</form>

Submits to /?q=…, so Enter searches from any route.
Pre-fills from the current ?q=.
The X button appears only when there is text. Clearing re-requests / when the
grid holds a server-filtered subset, or resets the filter in place when the full
catalog is already in the DOM.

index.astro — ?q= is now answered by D1, so results are correct at first
paint with no flash of the unfiltered catalog:

const searchParam = Astro.url.searchParams.get('q')?.trim() ?? '';
const isSearching = searchParam.length > 0;
plugins = isSearching ? await searchPlugins(db, searchParam) : await listPlugins(db);

The "catalog is empty" state is skipped while searching, so a zero-match search
shows the grid plus the ROMeo no-results panel instead of wrongly claiming no
extensions exist. The result heading names the term ("0 extensions for …").

db.ts — new searchPlugins(), a bound LIKE over
LOWER(name/description/category) reusing the shared column list and publisher
join so publisher name and verified badge still resolve.

Security

The term is bound, never interpolated, so the only pattern syntax reaching SQL
is the % wildcard:

.prepare(`… WHERE LOWER(p.name) LIKE ?1 OR …`).bind(`%${query.toLowerCase()}%`)

A test feeds '; DROP TABLE plugins; -- and asserts it lands in the bindings, not
the SQL text.

Verification

Check	Result
`npm run build`	exit 0
`npm test`	56/56 (6 new)
`tsc` on `src/`	clean
Type `nkit` on `/`	narrows to 2 cards, instantly
Type nonsense on `/`	all cards hide, ROMeo empty state shows
`/?q=nkit` (server)	HTML contains only the 2 NKit cards, input pre-filled
`/?q=zzzznomatch`	0 results, shows ROMeo no-results (not "catalog empty")
`/plugin/nkit`	search form present and submits to `/?q=`
X button	clears and restores all 4 cards

Note on scope

I kept the working client-side filter as-is rather than rewriting it — the task
described a symptom that didn't reproduce on the homepage, and the honest fix was
the missing cross-page wiring, not the filtering itself. If you did see the
homepage box fail, it was most likely a cached bundle; a hard reload should clear
it, and the ?q= path now works regardless.

This pull request was created by an AI agent (OpenHands) on behalf of the user.

Summary by CodeRabbit

New Features
- Search the plugin catalog using the search bar, including from pages that don’t display their own catalog.
- Searches can match plugin names, descriptions, and categories, and show the active search term with the results.
- The search bar is prefilled when the page is opened with a search query. A clear button lets you reset the search and return to the full catalog or clear an in-page filter.

…storefront The search box was dead on every page except the catalog. It lives in the shared Navbar, but the only handler was in index.astro, so typing on /plugin/*, /publisher/* or /dashboard did nothing at all. There was also no form, so Enter never submitted, no clear (X) control, and ?q= was handled client-side only. Client-side instant filtering (typing narrows the grid, zero matches reveal the ROMeo empty state) already worked on the homepage and is kept as-is. The changes: - Navbar: the box is now a real GET form to "/" with name="q", so Enter searches from any route. It pre-fills from ?q= and gains an X button that appears only when there is text; clearing re-requests "/" when the grid holds a server-filtered subset, or resets the filter in place otherwise. - index.astro: read ?q= and answer it in D1, so results are correct at first paint with no flash of the unfiltered catalog. The "catalog is empty" state is skipped while searching, so a zero-match search shows the grid + ROMeo no-results panel instead of claiming the catalog has no extensions. The result heading names the term. - db.ts: add searchPlugins(), a bound LIKE over LOWER(name/description/category) reusing the shared column list and publisher join. The term is bound, never interpolated, so the only pattern syntax reaching SQL is the % wildcard. tests/search.test.ts pins that down along with the matched columns and the row mapping.

Walkthrough

The shared navbar now submits searches to the catalog route. The catalog searches plugin names, descriptions, and categories on the server, then displays matching results or a search-specific zero-results view.

Changes: Catalog search

Layer / File(s)	Summary
Plugin search query `src/lib/db.ts`, `tests/search.test.ts`	`searchPlugins` matches the lowercased query against plugin names, descriptions, and categories. It binds the query, orders results by downloads and name, and maps publisher fields. Tests cover SQL conditions, parameter binding, result mapping, and empty results.
Catalog search results `src/pages/index.astro`	The catalog trims `q` and uses server-side search when the value is nonempty. Search results show the query, and zero-result searches use the results view. Client-side filtering initializes from the server-prefilled input.
Shared navbar search `src/components/Navbar.astro`	The navbar submits a GET form to `/` with the `q` parameter. Its clear button navigates to `/` for query-backed searches or resets the in-page filter otherwise.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Moderate · up to 64929

Searching from the navbar now works on every page, but results can be inconsistent. Searches by publisher, route, or platform return nothing when submitted from non-home pages. After a server search, editing the term or clearing filters cannot bring back plugins that were left out. Fix these before merging.

Security architecture risk: Low · up to 64929

Search now processes visitor-controlled queries on the server. The query is parameterized, uses existing catalog data, and does not expand privileges. No introduced security vulnerability was established; production query cost and abuse containment remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The repository-visible exposure is visitor-controlled filtering of the existing storefront catalog through its existing D1 binding. Search uses the same data projection as the previously available full listing, so the inspected query does not expand the accessible catalog data set.

Trust Boundaries and Controls

observed — Layout shares Navbar across public and authenticated pages. The search form contributes only q to the public catalog request; it does not serialize session or protected-page data. Dashboard routes retain authentication checks, and publisher editing retains its ownership check before rendering.

Resilience and Maintainability Implications

inferred — Nonempty requests add request-dependent lowercase substring matching. Neither the search nor the existing full-list query has a result limit. This warrants capacity consideration, but the inspected evidence does not establish exploitable resource exhaustion or measured service degradation.

Hardening Proposals

proposed — Validate worst-case search cost against expected catalog size and request volume, then consider query-length, result-size, or request-rate bounds where needed. This is capacity hardening, not a verified vulnerability.

Escape literal LIKE metacharacters.

The bound term still treats user-supplied % and _ as wildcards. For example, searching for % matches every database row, while the client-side filter treats % as literal text. Escape those characters and the escape character before adding the surrounding % wildcards, and specify the matching SQL ESCAPE clause. Binding already protects SQL syntax; this fix makes the search results correct. (sqlite.org)

Match the fields searched by the catalog input.

The client-side card search includes publisher name, routes, and platforms, but searchPlugins does not. A publisher name can therefore find a plugin while typing on the unfiltered homepage, then return no results when the same search is submitted from another route. Add the missing fields to the server search, or make both search paths use the same documented field set. (raw.githubusercontent.com)

Keep instant filtering valid after a server search.

When ?q= is present, this assignment puts only the first search’s matches in the DOM. The input handler then filters that subset. If a visitor replaces the search term with one that matches a different plugin, the page reports zero results until the visitor submits the form. The “Clear filters” button also cannot restore omitted plugins. Re-query when the term changes, or restore the full catalog before applying client-side filters. (raw.githubusercontent.com)

Show zero-result feedback in the server response.

This branch renders the search-results section for a zero-result ?q= search, but the no-results panel starts with hidden. Until the client script runs—and whenever it cannot run—the response shows “0 extensions” without the promised no-results message or actions. Set the panel’s initial visibility from total when rendering the search response. (raw.githubusercontent.com)
