# Behavior traces — QwikDev/qwik

Scanned commit 8eb4589be115eb8f2dabfd12c107dcc23647caec (2026-10-02). Generated by codevetter codevetter 1.15.0 on 2026-10-02.

Source inspection; upstream code and tests were not executed.

Four concrete flows were followed across their owning files: a server-rendered page and resumed event, a route action, project scaffolding, and Insights ingestion. These traces describe source control flow rather than observed runtime executions. They expose explicit synchronization points: SSR flushes, streamed-container readiness, action submission serialization, and database writes after response creation.
- Page request, step 1: createQwikRouter.router computes the origin, combines body limits, calls fromNodeHttp, and passes the resulting event to requestHandler. — [packages/qwik-router/src/middleware/node/index.ts#L48-83](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/node/index.ts#L48-L83)
- Page request, step 2: requestHandler obtains getRouterConfig, loads routes through loadRequestHandlers/loadRoute, resolves middleware, and calls runQwikRouter. — [packages/qwik-router/src/middleware/request-handler/request-handler.ts#L25-33](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/request-handler.ts#L25-L33) [packages/qwik-router/src/middleware/request-handler/request-handler.ts#L69-89](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/request-handler.ts#L69-L89) [packages/qwik-router/src/middleware/request-handler/request-handler.ts#L113-136](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/request-handler.ts#L113-L136)
- Page request, step 3: runQwikRouter creates RequestEvent and drives runNext; page middleware runs actions/loaders before renderQwikMiddleware supplies serverData and a stream to the application's render function. — [packages/qwik-router/src/middleware/request-handler/user-response.ts#L29-54](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/user-response.ts#L29-L54) [packages/qwik-router/src/middleware/request-handler/user-response.ts#L85-103](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/user-response.ts#L85-L103) [packages/qwik-router/src/middleware/request-handler/resolve-request-handlers-core.ts#L131-138](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/resolve-request-handlers-core.ts#L131-L138) [packages/qwik-router/src/middleware/request-handler/resolve-request-handlers-core.ts#L795-809](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/resolve-request-handlers-core.ts#L795-L809)
- SSR step: renderToStream resolves manifest/base, creates StreamHandler and SSRContainer, calls setServerPlatform and container.render, awaits the render promise, then flushes. — [packages/qwik/src/server/ssr-render.ts#L63-96](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/server/ssr-render.ts#L63-L96) [packages/qwik/src/server/ssr-container.ts#L177-198](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/server/ssr-container.ts#L177-L198)
- Resumed click step: qwikloader dispatch reads q-e:click, locates the container, waits for its ready marker when streaming, resolves/imports the handler, and invokes it with captured IDs. — [packages/qwik/src/qwikloader.ts#L130-144](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/qwikloader.ts#L130-L144) [packages/qwik/src/qwikloader.ts#L318-360](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/qwikloader.ts#L318-L360) [packages/qwik/src/qwikloader.ts#L218-235](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/qwikloader.ts#L218-L235)
- QRL invocation step: _run obtains DomContainer, waits for container data, creates invocation context, deserializes capture deltas, and calls runEventHandlerQRL; that function inflates the host element and invokes through retryOnPromise. — [packages/qwik/src/core/client/run-qrl.ts#L84-98](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/core/client/run-qrl.ts#L84-L98) [packages/qwik/src/core/client/run-qrl.ts#L45-76](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/core/client/run-qrl.ts#L45-L76) [packages/qwik/src/core/client/dom-container.ts#L180-211](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/core/client/dom-container.ts#L180-L211)
- Action flow: routeActionQrl.submit queues behind pendingDispatch and updates currentAction; the router task calls submitAction, actionHandler parses/validates/calls the QRL, and the client receives result plus invalidation hashes. — [packages/qwik-router/src/runtime/src/server-functions.ts#L93-147](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/runtime/src/server-functions.ts#L93-L147) [packages/qwik-router/src/runtime/src/qwik-router-component.tsx#L608-647](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/runtime/src/qwik-router-component.tsx#L608-L647) [packages/qwik-router/src/runtime/src/use-endpoint.ts#L55-73](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/runtime/src/use-endpoint.ts#L55-L73) [packages/qwik-router/src/middleware/request-handler/handlers/action-handler.ts#L81-121](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik-router/src/middleware/request-handler/handlers/action-handler.ts#L81-L121)
- Scaffold flow: create-qwik.mjs calls runCli; arguments choose runCreateCli, which builds a template manager, validates the target-directory policy, and invokes createApp. — [packages/create-qwik/create-qwik.mjs#L1-3](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/create-qwik/create-qwik.mjs#L1-L3) [packages/create-qwik/index.ts#L7-23](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/create-qwik/index.ts#L7-L23) [packages/create-qwik/src/run-create-cli.ts#L56-89](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/create-qwik/src/run-create-cli.ts#L56-L89)
- Scaffold write/install flow: createApp calls createFromStarter, updateApp merges integration files, commit creates directories and writes files, and installDeps delegates to runCommand using execa. — [packages/create-qwik/src/create-app.ts#L36-49](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/create-qwik/src/create-app.ts#L36-L49) [packages/create-qwik/src/create-app.ts#L71-94](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/create-qwik/src/create-app.ts#L71-L94) [packages/qwik/src/cli/add/update-app.ts#L44-76](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/cli/add/update-app.ts#L44-L76) [packages/qwik/src/cli/utils/utils.ts#L8-34](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/qwik/src/cli/utils/utils.ts#L8-L34)
- Insights persistence flow: plugin@db initializes the libSQL client; onPost parses and validates telemetry, sends an OK response, then resolves manifest/application records and awaits updateEdge/updateRoutes counter updates or inserts. — [packages/insights/src/routes/plugin@db.ts#L7-20](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/insights/src/routes/plugin%40db.ts#L7-L20) [packages/insights/src/routes/api/v1/[publicApiKey]/post/index.tsx#L8-43](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/insights/src/routes/api/v1/%5BpublicApiKey%5D/post/index.tsx#L8-L43) [packages/insights/src/db/query.ts#L270-293](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/insights/src/db/query.ts#L270-L293) [packages/insights/src/db/query.ts#L309-329](https://github.com/QwikDev/qwik/blob/8eb4589be115eb8f2dabfd12c107dcc23647caec/packages/insights/src/db/query.ts#L309-L329)
