TypeScript 6.0's new isolatedModules default breaks const enums, namespaces, and type-only imports. Here's how to fix your build pipeline before deployment fails.

Run Claude Code autonomously in CI pipelines to perform code review, generate tests, and auto-fix failures on every pull request—with production patterns for cost control and safety.

Most TypeScript runtime validation fails because developers misunderstand when to use type predicates versus assertion functions. Learn the patterns that actually narrow types correctly in production codebases.

Most readonly bugs stem from shallow enforcement and type widening. Learn when TypeScript's readonly protects your arrays and tuples—and when it silently fails.

Most monorepo build failures stem from misunderstood project references. Learn how composite projects, incremental builds, and tsc -b actually work—and the subtle configuration mistakes that destroy build performance at scale.

Master the never type for exhaustive checks, impossible state elimination, and compile-time guarantees. Learn practical patterns that catch bugs before they reach production.

Most production TypeScript bugs stem from a single assumption: that strict mode catches every type safety hole. It doesn't. The exactOptionalPropertyTypes flag exposes runtime crashes that strict mode silently permits—here's why teams overlook it and how to fix it.

Most Server Actions fail at scale because teams treat them as internal functions instead of public POST endpoints. Learn the production patterns for authentication, validation, multi-tenant authorization, and choosing between Server Actions and Route Handlers in Next.js 16.

Most Claude Code cost overruns stem from invisible context accumulation and cache misses. Learn token budgets, caching strategies, and production-grade cost control patterns the billing dashboard won't reveal.

How teams use Git worktrees and isolated subagents to coordinate breaking changes across monorepo packages without merge conflicts or context collision.

Master recursive types to model JSON values, file systems, and nested data structures. Learn production patterns that avoid TypeScript's recursion depth limit while maintaining type safety.

Most CI pipelines waste minutes waiting for tsc to transpile code that production never uses. The --noEmit flag and type-only checks unlock parallel builds that finish 3x faster while catching every type error.
