Code Quality Standard

The ScaleMatic engineering bar: TypeScript rigor, data separated from rendering, discriminated-union state, pragmatic testing where wrongness is expensive, and transform/opacity-only performance — so a stranger can extend the repo without fear.

Executive summary

What problem does this solve?

Premium software is as much about the inside as the outside, but most codebases rot into any-typed, test-free junk drawers nobody can safely change. Six months later the original author can't extend it either.

Business outcome

  • A repo a stranger can understand in five minutes and extend without fear
  • State modeled as discriminated unions, not tangles of booleans
  • Tests where wrongness is expensive, ceremony where it isn't
Revenue maturityLvl 48

The ScaleMatic engineering bar for every non-trivial codebase.

Implementation

6 steps, start to finish

Types describe the domain, not the shape.

  • strict: true always; no any unless interfacing with an untyped boundary — then wrap it in a typed function at the edge
  • Name interfaces after the business concept (Lead, ApprovalState, KpiMetric), not the shape (DataItem)
  • Prefer discriminated unions over boolean flags for state
  • Derive, don't duplicate: keyof, typeof, ReturnType over re-declared shapes
