Core rules
- Follow the Google JavaScript style guide; TypeScript adds typing rules on top.
- Use explicit types on exported/public APIs; avoid
anyunless justified. - Prefer
interfacefor object shapes; usetypefor unions/intersections. - Use
readonlyandas constwhere values are immutable. - Naming mirrors JS: camelCase members, PascalCase types/classes.
- Use ES modules; enable strict compiler options in tsconfig.
Quick checklist
