Maintaining separate REST types and frontend client types can be a lot of overhead in TypeScript-heavy teams. With tRPC, the API types flow directly to the client, which reduces duplication and keeps refactors safe. Runtime validation still matters, s

Rails conventions support RESTful API development. I use resourceful routing for standard CRUD operations. Controllers inherit from ActionController::API for API-only apps. JSON serialization with Jbuilder or Active Model Serializers structures respon

Formatting consistency matters, but humans shouldn’t be the ones enforcing it in code review. Prettier makes diffs smaller and reviews more focused on logic. I keep the config minimal and aligned with team expectations (singleQuote, trailing commas, ~

Delegates enable objects to communicate events and customize behavior. The delegate pattern uses protocols to define a contract—I create a protocol with optional and required methods, and the delegating object holds a weak reference to avoid retain cy

Ruby's metaprogramming enables dynamic method definition and interception. method_missing catches undefined method calls, allowing DSL creation and proxy patterns. I implement it carefully with respond_to_missing? for proper introspection. define_meth

Action Cable brings WebSocket support to Rails, enabling real-time features like live notifications, collaborative editing, or chat systems. Clients subscribe to channels that broadcast updates when server-side events occur. I use Redis as the pub/sub

One of the easiest ways to reduce frontend complexity is to be consistent about API responses. I keep a small helper that always sets Content-Type: application/json; charset=utf-8, uses a stable error envelope (error + optional details), and returns c

Sign in with Apple provides secure, privacy-focused authentication required for apps with third-party login. Users create accounts with Face ID or Touch ID, and Apple generates unique identifiers per app. I use ASAuthorizationController to initiate th

Formsets handle multiple forms on one page. I use modelformset_factory for editing existing objects and inlineformset_factory for related objects. The extra parameter controls empty forms shown. I validate formsets with formset.is_valid() and save wit

Sitemaps help search engines discover and index pages. Django's sitemap framework generates XML sitemaps automatically. I create sitemap classes for each content type, defining items(), lastmod(), changefreq(), and priority(). For large sites, I use s

In-flight request count is a simple but powerful saturation signal. I keep an atomic.Int64 gauge that increments at the start of a request and decrements in a defer, which makes it robust even on early returns. This gauge can be exported via expvar, P

Deploys got a lot calmer once I treated SIGTERM as a first-class signal instead of an afterthought. In Kubernetes (and most PaaS platforms), you’re expected to stop accepting new requests quickly while finishing in-flight work. The worst failure mode
