typescript

TypeScript code style and type-safety guide for LobeHub. Read before writing or editing any `.ts` / `.tsx` / `.mts` — covers `interface` vs `type`, `Record<PropertyKey, unknown>` over `any`/`object`, `as const satisfies`, `@ts-expect-error` over `@ts-ignore`, `import type` (`separate-type-imports`), `async`/`await` + `Promise.all`, `for…of` over indexed `for`, and the no-silent-`.catch(() => fallback)` rule. Also use when reviewing type quality, deciding module augmentation (`declare module`) over `namespace`, or designing extensible types (e.g. `PipelineContext.metadata`). Triggers on any TypeScript file edit, 'fix the type', 'why is this `any`', 'should this be interface or type', 'eslint type-import', 'ts-expect-error'.
