# The `transformers` generator — its skill This file is the DESIGN of your ejected `transformers` generator (`generators/transformers/`): **to change the generator, edit this skill first, then make the code match it** — a diff to `generators/transformers/` that has no covering sentence here is incomplete. ## What it emits Per-schema `to<Name>()` / `from<Name>()` converters that turn wire JSON into typed values and back — the bridge for `dateType: Date` clients. ## Design decisions that must hold - **Requires `dateType: Date`** (declared as `dateTypes: ['Date']`, so a mismatched selection fails fast): the converters assign `Date` objects to fields the sdk types as `Date`, which only type-checks in that mode. - **Imports the sdk's schema TYPES** (so `typescript` is required) and nothing else. - Converters are pure and total: every named schema gets a pair, nested structures recurse, and a missing optional stays missing. ## The stage files `render.ts` holds the whole converter renderer; `index.ts` is the entry. Naming comes from the TypeScript printer (`@redocly/client-generator/printers/typescript`). ## Ejecting it `redocly eject-generator transformers` copies this generator's TypeScript source folder to `generators/transformers/`, exactly as we wrote it, importing `@redocly/client-generator` and `@redocly/client-generator/printers/typescript`. Running a `.ts` generator uses Node's type stripping (Node 22.18, 23.6, or newer); newer built-in versions merge in per file with `--update`. Change which fields are converted, or how, and regenerate. ## The modify loop 1. Edit this skill: state the new behavior or decision. 2. Make `generators/transformers/` match it. 3. Run `redocly generate-client` and inspect the `git diff` of the generated output — generated files are never hand-edited. Newer built-in versions merge in with `redocly eject-generator transformers --update`.
