TypeScript discipline that scales past 100k lines
TypeScript has won. By 2026, any new JavaScript codebase that ships without TypeScript is making a deliberate, documented exception to the industry default. But adopting TypeScript and using TypeScript well are different disciplines — and most large codebases we audit have technically migrated to TypeScript while preserving the type safety guarantees of plain JavaScript.
Below is the discipline that distinguishes a TypeScript codebase that catches bugs from one that decorates them.
Strict mode and noUncheckedIndexedAccess from day one
tsconfig.json should enable `strict: true`, `noUncheckedIndexedAccess: true`, `noImplicitOverride: true`, and `exactOptionalPropertyTypes: true`. Each of these catches a class of bug that the default settings let through. Retrofitting them onto a codebase later is painful; enabling them in week one is free.
Disable `any` in CI with ESLint's `no-explicit-any` and `no-unsafe-*` rules. A codebase with even occasional `any` usage degenerates into a JavaScript codebase with type decorations within 18 months — we have measured this pattern across dozens of audits.
Runtime validation at the trust boundary
TypeScript types disappear at runtime. Any data crossing a trust boundary — HTTP request body, environment variables, third-party API response, file upload — must be validated at runtime with Zod, Valibot, or an equivalent schema validator. Inferring the TypeScript type from the Zod schema (`z.infer<typeof Schema>`) keeps the static and runtime types in lockstep.
Skipping runtime validation is the single most common cause of production type errors we debug. The TypeScript compiler will happily believe a `string` is whatever the API documentation claimed it was — the API server is under no such obligation.
Type-driven development for domain logic
Discriminated unions, exhaustive switch statements, and branded types are the trio that makes TypeScript meaningfully safer than JavaScript for domain logic. Model your state as a discriminated union (`type Order = { status: 'draft', ... } | { status: 'paid', ... } | ...`) and rely on the compiler to enforce exhaustive handling.
Branded types (`type UserId = string & { __brand: 'UserId' }`) prevent the entire category of bugs where the wrong ID is passed to a function expecting a different ID. Cheap to add, expensive to retrofit, infinitely worth it.
