codegen-over-complex-types

Sometimes the best type-level code is no type-level code at all. When types become extremely complex, when they mirror external schemas (APIs, databases, protocols), or when they need to stay synchronized with changing external sources, code generation is often a better solution than sophisticated type-level programming.

Code generation trades compile-time complexity for build-time generation, often resulting in simpler, more maintainable code that stays in sync with its source of truth.

When types become too complex or must stay synchronized with external sources, generate them from schemas rather than writing sophisticated type-level code.

Use when types become extremely complex. Use when types mirror external schemas. Use when maintaining type-to-schema mappings. Use when types require extensive type-level logic. Use when types drift from data sources. Source: marius-townhouse/effective-typescript-skills.
