The gate before the quality gate.

What it is

The type gate: every file is typed in strict mode. `tsc --noEmit` runs in GitHub Actions on every push and pull request, and locally before a release.

What it does for your business

For your business it means the class of mistake that breaks a checkout form at the worst moment is caught before a deploy, in private, instead of in front of a customer.

Why it earns its place

The class of mistake that breaks a checkout or a portal often lines up in the type system before it reaches a browser. A type check is cheaper than a client finding it.

The type checker runs in GitHub Actions on every push and pull request, and locally before a release. Red code does not merge.

GitHub Actions

The last release ran `tsc --noEmit` and the production build with zero errors. GitHub Actions now runs the same check on every push and pull request.

How it runs here

The repository runs TypeScript with strict checks. `tsc --noEmit` runs in GitHub Actions on every push and pull request, and locally before a release; the production build also type-checks.

A TYPE THAT TRAVELS

export type Tool = {  slug: string;  name: string;  tag: string;}; export function toolBySlug(slug: string): Tool | undefined {  return TOOLS.find((tool) => tool.slug === slug);}

When it runs

Every change, before the production build. A red type check is not a warning.

Who owns it

Build writes the types. QA runs the check. The operator sees the release statement, not the compiler output.

What it does not claim

Types catch structural mistakes, not false copy, a bad price or a missed legal requirement. The claims ledger and a human read cover those.

THE REFERENCE

The manual above is ours. The vendor's reference is the place to check an API, a version or a limit.
