TypeScript design patterns that use the type system to enforce correctness at compile time — the builder pattern with required-field tracking, type-safe state machines and event emitters, dependency injection, plugin systems, recursive/deep-readonly utility types, type-safe module encapsulation, advanced generic constraints, and typed API clients. Use when structuring a class or module so invalid usage fails to compile rather than throwing at runtime, e.g.…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TypeScript Design Patterns Structural patterns that push correctness into the type system: a class or module shaped so the compiler rejects a misuse the runtime would otherwise have to catch. ## Mindset A pattern here earns its place only if it converts a runtime failure into a compile error. Before reaching for one, ask what invalid usage it should make impossible to write, not just cleaner to read — a builder that still lets `.build()` run with missing fields is a fluent API, not a type-safe one. Prefer composing the type system's own primitives (discriminated unions, conditional types, mapped types) over hand-rolled runtime checks wherever the invalid state can be excluded at the type level instead of merely caught. Treat generics as free specificity, not decoration: a generic parameter with no constraint is barely more useful than `any`, and a pattern that leaves one unconstrained has not finished its job. ## When to Apply Use this skill when: - Enforcing required fields at compile time with the builder pattern - Modeling application or connection state as a type-safe state machine - Typing an event emitter so payloads are checked against their event name …

How to install
mdr add pantheon-org/tekhne/typescript-advanced-design-patterns@sha256:263356b133b3fca3The line at the top of this page pins the label git:20260923.7852cb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
