Presetter v9: Scoped Namespace, TypeScript 6, and Release Hardening

Presetter v9 is here - a major release that modernizes the toolchain, reorganizes the preset ecosystem, and hardens the release pipeline. Every preset moves to the @presetter/* scope, TypeScript 6 becomes the public baseline, and three new presets join the family: node, bun, and storybook.

📦 A scoped namespace​

All preset packages now ship under the @presetter/* scope. The main presetter CLI keeps its unscoped name, but every preset has a new home:

v8 (old)v9 (new)
presetter-preset-essentials@presetter/preset-essentials
presetter-preset-esm@presetter/preset-esm
presetter-preset-react@presetter/preset-react
presetter-preset-monorepo@presetter/preset-monorepo
presetter-types@presetter/types

The full lineup at v9: essentials, node, bun, esm, cjs, hybrid, web, react, next, rollup, strict, monorepo, and storybook.

🧰 TypeScript 6, native typechecking, and ES2024​

TypeScript 6 is now the required peer dependency. The default compile target moves up to ES2024, and the essentials preset enables noUncheckedIndexedAccess for safer indexed access. The tsconfig templates were simplified to lean on TypeScript 6's strict defaults instead of carrying explicit overrides.

The Presetter repository itself also moved its workspace typecheck path to tsgo via @typescript/native-preview, so maintainers can validate the monorepo against the native compiler path while published presets continue to declare the TypeScript 6 peer baseline.

// noUncheckedIndexedAccess makes indexed reads `T | undefined`
const value = record[key] ?? fallback;

🆕 Three new presets​

  • @presetter/preset-node — a Node-tuned TypeScript configuration layered on essentials.
  • @presetter/preset-bun — a standalone preset for Bun projects, complete with Bun ambient types.
  • @presetter/preset-storybook — a standalone Storybook setup that generates .storybook/main.ts, Storybook scripts, ESLint story rules, and a Vitest browser project.
presetter.config.ts
import next from '@presetter/preset-next';
import storybook from '@presetter/preset-storybook';
import { preset } from 'presetter';

export default preset('app', {
  extends: [next, storybook],
});

✨ Quality-of-life features​

  • presetter bootstrap --projects now accepts package names, not just globs.
  • lint-staged pre-commit and pre-push hooks ship out of the box.
  • git-cliff powers changelog generation, replacing Standard Version.
  • Monorepo sub-level Vitest configuration lets packages refine their own test setup.
  • Package info is displayed while bootstrapping.
  • Provenance publishing is enabled for the release workflow, and CI now tracks active Node LTS lines plus latest instead of the EOL Node 20 line.
