@panth977: open-source TypeScript packages for schema-safe backends

The problem

TypeScript types disappear at runtime, so they don't validate what a function actually receives or returns. On a backend that means the same schema gets written three times (validation, docs, types) and drifts. Caching and logging get the same treatment: copied by hand into every function.

What I built

• @panth977/functions: define a function with zod input and output schemas and wrappers; every call gets a context (used for logs and disposal).
• @panth977/routes with routes-express and routes-hono: one typed schema per endpoint gives the HTTP handler, the OpenAPI docs and the types. Middleware, plain HTTP and SSE included.
• @panth977/cache and cache-redis: wrappers for caching a single object, many objects and collections, with invalidation hooks.
• @panth977/logs and @panth977/tools: log helpers and small utilities such as pub/sub.

Result

The cache and logging designs in the case studies above are built on these packages, and the blog posts linked here walk through them with code.
