refactor: keep SQL out of the beacon's browser bundle - #113
Conversation
`src/beacon-events.ts` held both halves of a beacon event. The browser half builds the query string an event travels in, and the SQL half reads the same parameters back off a delivered log record. Browser code imports the package root, so a site folding the beacon into its own bundle took the SQL with it. The SQL constants sat at module scope, so a bundler kept their initialisers along with `decodedParameter` and `quoted` to compute them. An entry importing `beaconQueryString` and sending one event, bundled and minified with rolldown, came to 464 bytes and 331 gzipped. Split, the same entry is 241 bytes and 215 gzipped, and it carries no `url_decode`, no `url_extract_parameter` and no `strpos`. `beacon-events.ts` keeps the envelope and now imports nothing at all. `beacon-rows.ts` holds the three column expressions and the two row conditions, and imports the parameter names from next door. Every export keeps its name and the package root exports the same set, so nothing outside this repository changes. `pack-check.sh` gains the guard that keeps it that way. The forbidden-import check it already runs cannot see this, because the package root legitimately reaches SQL and every one of those imports is a relative path it allows. The new check reads the built envelope module and fails on any import at all.
📝 WalkthroughWalkthroughThe change separates browser beacon construction from SQL log-row reading. Package consumers import each concern from its dedicated module. Tarball validation now checks that the browser beacon envelope exists and has no imports. ChangesBeacon module separation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change removes SQL from the browser bundle, but the packaging guard can miss multiline dynamic imports and therefore may not catch every future regression. The PR is mergeable with explicit owner follow-up to make the check syntax-aware and add a regression fixture. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

It also explains why user-facing documentation was not added. Full details: Linked Issues checkExplanation The changes satisfy issue Full details: Out of Scope Changes checkExplanation The changes are limited to separating beacon browser logic from SQL row-reading logic, updating imports and tests, preserving exports, and adding the required bundle guard.

Make the envelope import check multiline-aware.
grep applies this pattern one line at a time, so it misses valid dynamic imports with a line break, such as import(\n "./heavy.js"). Use a JavaScript-aware parser or token-aware scan, and add a regression fixture.
