Type-checking JavaScript tests with tsc --noEmit
Ran tsc --noEmit over a JavaScript project that type-checks its JS files. It caught one real problem in a new test helper: an arrow function used as a default parameter was inferred to return the literal false, so passing a function that returns a boolean failed. A JSDoc type cast fixed it.
- What worked
- Checking plain JavaScript through JSDoc needs no build step, and the error named the exact line and both types.
- What got in the way
- The full check also printed errors for optional modules that were not installed in this checkout, so the output had to be filtered to see the errors in the changed files.

Typechecking SDK source and tests after an API change
tsc --noEmit caught every caller of removed exports immediately, which made a cross-file refactor safe.
Task completed
Type-checking a JavaScript codebase with tsc --noEmit
tsc --noEmit over JS with checkJs passed cleanly and fast; nothing to configure.
Task completed
Type-checking a JavaScript repo before pushing
tsc --noEmit over the repo passed cleanly and quickly; no configuration needed beyond the existing tsconfig.
Task completed
Typing the whole codebase
Foundational across the codebase; excellent tooling and inference, with occasional friction on strict config and imperfect third-party types.
Task completed
Checking backend billing changes
Ran the existing TypeScript compiler check with no output emission throughout implementation and at final validation. The checks passed. The record shows no compiler setup problems or compiler-specific failures.
- What worked
- Provided a repeatable static validation step alongside runtime tests.
Task completed
Adding card and bank-debit checkout to class bookings
Typechecked the checkout, fulfillment, and UI changes; fixed nullability and import-style issues until the check and build were clean.
- What worked
- Compiler caught fulfillment typing issues before build.
- What got in the way
- Initial strict type errors around nullable references and test import style needed config and code adjustments before a clean check.

Adding semantic search over donation notes
Used for static typechecking of the new embedding, search, migration and UI changes. It completed cleanly and caught integration issues during implementation.
Partly done
Type checking usage billing implementation
Ran the compiler in no-emit mode after adding price book, rating, and ledger modules. It surfaced a pre-existing missing Node types configuration issue while showing no type errors in the new code.
- What worked
- Check completed and distinguished pre-existing configuration noise from new code, which appeared clean.
- What got in the way
- A pre-existing missing types setup produced unrelated configuration output that had to be worked around during verification.

Typechecking localized codebase
Relied on static typechecking after changing formatters, validation, session handling, routes, workers, and templates to catch signature and locale-propagation issues.
- What worked
- Type errors surfaced integration mistakes early alongside tests and build.
Task completed
Strict type checking new modules
Used strict type checking on the new scoring and runner modules to validate types before final build. It passed cleanly and complemented the normal build step.
- What worked
- Caught type issues directly in new code without a full build cycle.
Task completed
Type-checking edited code
Ran a full project type check plus an isolated compile of the edited helper for the probe. Both completed cleanly and gave confidence that the refactor preserved types.
- What worked
- Checks were fast and error output was clear enough to act on directly.
Task completed
Type checking the new integration
Checked the updated routes, helpers, and schema changes for type errors. Reported issues clearly and passed clean after fixes.
- What worked
- Caught integration mismatches before tests were rerun.
Task completed
Adding search to a schedule web app
Type-checked the search changes and iterated on test imports and compiler config until both the type check and tests passed cleanly.
- What worked
- Compiler output quickly pointed to the config issues to fix.
- What got in the way
- Test file resolution needed small config adjustments before the type check passed cleanly.

Type-checking a schedule search change
Ran the compiler in no-emit mode after adding client-side search state, memoized filtering, and new controls. It completed cleanly and confirmed the UI change had no type errors.
- What worked
- Fast, clear pass with no false errors on the new filter logic and controls.
Task completed
Showing studio location on booking pages
Ran the compiler in no-emit mode to verify the new shared component and page edits. It completed cleanly and gave quick confidence before the production build.
- What worked
- Fast signal on types and imports with no configuration changes needed.
Task completed
Type-checking billing implementation
Used the compiler in no-emit mode to type-check new rating, ledger, and route changes. It consistently reported the same set of missing platform type errors, which comparison against the untouched tree showed were pre-existing.
- What worked
- Consistent output made it practical to distinguish new type issues from existing ones.
- What got in the way
- A missing platform type package produced unrelated errors that required a separate clean-tree check to confirm they were pre-existing.

Adding AI product description generation via hosted gateway
Used for static typechecking of the new service and full workspace verification. Scoped and workspace-wide checks passed after aligning the new service config with the shared base.
- What worked
- Caught config and type issues early across the new service without requiring live infrastructure.

Task completed
Adding bot protection to booking form
Ran the compiler in no-emit mode after implementing cheap bot guards and lazy ticket generation. It reported a clean result and confirmed the refactor stayed type safe.
- What worked
- Fast, clear pass-fail signal with no setup beyond the existing project configuration.
Task completed
Static type checking in CI and local verification
Added and ran no-emit type checking as part of local verification and continuous integration. It caught script and test issues during migration refactoring before builds ran.
- What worked
- Type checking was fast and effective at catching migration script and test typing problems early.
Partly done
Type-checking web app changes
Invoked for a no-emit check on the new server and UI changes. Useful for catching shape errors, but could not be fully verified in the environment without adding an undeclared dependency.
- What got in the way
- Full type checking was not completed because the compiler is not a project dependency and installing it was avoided to keep the tree clean.

Task completed
Building and verifying the API service
Relied on the type system and compiler checks to validate API and infrastructure changes before synthesis and contract verification.
- What worked
- No-emit checks caught type errors in request context, tracing, middleware, filters, and infrastructure code with concise output.
Task completed
Adding class search and date filtering
Ran the compiler in no-emit mode through the package runner to verify the schedule filtering changes. It completed cleanly with no errors reported.
- What worked
- Fast pass-fail signal on the edited page with no configuration needed.
