Consolidates the five overlapping orchestrion injection mechanisms (subscribe-injection
transform,
injectDiagnosticsmodule-list banner, Turbopack loader append,onInjectbridge, per-path marker writes) into one always-on
tracingChannelImportoverride thatsplices a single snippet into every instrumented module.
Why:
g.bundler(clobbering earlier pushes), Bun setbundler = true(special-cased inthree places).
subscription design (Node's 1024-channel cap). Now they're only subscribed of they're actually loaded.
customTransformsnever survived webpack/Turbopack's serialized loader options, soinjectChannelSubscriberssilently never worked there.How:
orchestrionModuleInjected("<module>", <factory?>)when themodule is evaluated: records it on the marker, stores its subscriber factory (keyed by
real
state.module.name— no more reverse lookup or path-splitting heuristic), emitsthe client event. Record + emit only — no
addIntegration; Cloudflare listens for theevent instead to install factories registered after per-request
init().g.bundler = g.bundler || [].orchestrion.module-runtime-injected→orchestrion.module-injected.createLoader— transforms are baked into our loadermodule, so only JSON crosses the Turbopack boundary; webpack plugin configures upstream
via
loaderPath/cacheVersioninstead of patching its rule.resolveId/onResolve/aliasfallbacks per bundler; Turbopack gets an absolute-path
importSpecifierloader option.mongodb, …) — they now announce on the marker/event too.
Removed:
injectChannelSubscribers(+ 4 framework call sites), deadshouldInjectDiagnostics,the module-list banner, the Turbopack append snippet,
marker.onInject+ init-timebridge,
registerOrchestrionChannelIntegration, thebundler: truespecial cases.Deps:
@apm-js-collab/code-transformer-bundler-plugins^0.7.3→^0.7.4(adds theloader factory and webpack
customTransformsforwarding this builds on).
