Analyzer::Javascript::Remix
Overview
Remix v2 is filesystem-routed under app/routes/. The route URL
is derived from the filename via dot-flat naming and a handful
of special prefixes:
app/routes/_index.tsx → GET /
app/routes/about.tsx → GET /about
app/routes/users._index.tsx → GET /users
app/routes/users.$id.tsx → GET /users/{id}
app/routes/_auth.login.tsx → GET /login (_auth is a
pathless layout
— no URL effect)
app/routes/api.users.ts → exports drive verbs
app/routes/$.tsx → catch-all
Verb detection:
.tsx/.jsxfiles render a page — emit GET.- Files exporting
loaderadd GET (or keep it). - Files exporting
actionadd POST / PUT / PATCH / DELETE (Remix dispatches every non-GET toactionat runtime; we surface the full set so downstream tooling can fan out). - Resource-only
.ts/.jsfiles withoutloaderoractionare skipped — they're not handler routes.
Out of scope for this first cut:
- Per-handler request-helper scanning. Remix loaders / actions
receive
{ request, params, context }— accurate read tracking needs cross-call value flow. Path placeholders still surface via the optimizer. - Optional segments
($lang)(translated to a literallangtoday; Remix folds optionality into a wildcard match that's hard to represent without per-route alternatives). - The legacy v1 nested-folder convention — v2 flat is what the toolchain has been on since Remix 1.15 / Remix 2.
