@swarmmachina/standards

Shared ESLint, Prettier, TypeScript and Git tooling for SwarmMachina packages.

Quick start

pnpm add --save-dev @swarmmachina/standards

{
  "scripts": {
    "check": "swm-standards check",
    "fix": "swm-standards fix"
  },
  "swmStandards": {
    "preset": "js"
  }
}

Presets: js, typescript, vue, vue-typescript. Override the project setting for one command with --preset and optionally pass paths:

swm-standards check --preset vue src test

check runs Prettier then ESLint; fix runs ESLint fixes then Prettier writes. The CLI never guesses a preset and does not run the TypeScript compiler.

Compatibility

| Contour | Consumer installs | Notes | | ------------------ | ------------------------------------------------------------------------- | ------------------------------------------ | | JavaScript | @swarmmachina/standards | No TypeScript toolchain | | Vue/JavaScript | @swarmmachina/standards | vue-eslint-parser is bundled | | TypeScript compile | standards + [email protected] | Extends the shared tsconfig | | TypeScript lint | standards + TS7 native alias + TS6 API alias + [email protected] | See below | | Vue/TypeScript | Same lint sidecar | TS7 embedded-language type checking varies |

Supported runtime and pinned tools:

• Node.js ^22.13.0 || 24.x
• pnpm 11.15.1
• TypeScript compiler 7.0.2
• ESLint 10.7.0
• Prettier 3.9.6

TypeScript 7

Compiler-only projects can install TypeScript normally:

pnpm add --save-dev @swarmmachina/standards [email protected]

{
  "extends": "@swarmmachina/standards/tsconfig",
  "compilerOptions": {
    "rootDir": "src",
    "outDir": "dist"
  },
  "include": ["src"]
}

The config enables strict checking, NodeNext, ES2024, declarations and source maps. Projects own rootDir; Node globals require "types": ["node"].

TypeScript 7.0 has no stable programmatic API, while [email protected] supports TypeScript >=4.8.4 <6.1.0. Linting therefore uses the official side-by-side layout:

pnpm add --save-dev \
  @swarmmachina/standards \
  @typescript/native@npm:[email protected] \
  typescript@npm:@typescript/[email protected] \
  [email protected]

Here tsc is TS7, tsc6 is the transition compiler, and typescript-eslint receives the supported TS6 API. Standards does not claim native TS7 parser support or suppress unsupported-version warnings.

For Vue <script lang="ts">, the vue-typescript preset composes vue-eslint-parser with this sidecar. Template and TS syntax linting works; Volar and other embedded-language type tooling may still require TypeScript 6.

Public API

| Export | Contract | | ------------------------- | ----------------------------- | | ./eslint-js | JavaScript | | ./eslint-typescript | JavaScript + TypeScript | | ./eslint-vue | JavaScript + Vue | | ./eslint-vue-typescript | JavaScript + TypeScript + Vue | | ./prettier | Shared Prettier config | | ./tsconfig | Strict TS7 compiler base | | ./setup-hooks.mjs | Git hook installer | | swm-standards | check/fix CLI |

Direct ESLint composition remains supported:

import config from '@swarmmachina/standards/eslint-js'

export default config

Prettier can also be referenced without the CLI:

{
  "prettier": "@swarmmachina/standards/prettier"
}

Legacy 1.x paths (./eslint.config.mjs, ./eslint-ts, ./tsconfig.base.json and their code-style forms) remain available. New projects should use the explicit names above.

Migration from 2.x

Version 3.0.0 changes the license for first-party code from Apache-2.0 to MPL-2.0. Runtime behavior, package exports and tooling compatibility are unchanged. Existing 2.x releases remain available under Apache-2.0; review the MPL-2.0 terms before upgrading.

Migration from 1.2.0

1. Move to Node.js 22.13+ or 24 and pnpm 11.15.1.
2. Prefer swm-standards check|fix and declare swmStandards.preset.
3. For direct composition, replace generic paths with eslint-js, eslint-typescript, eslint-vue or eslint-vue-typescript.
4. For TS7 linting, install the TS7/TS6 side-by-side dependencies above.
5. Set project-owned rootDir and Node types where required.
6. Replace package-lock.json with pnpm-lock.yaml and rerun the full gate.

Consumers still pinned to 1.2.0 may temporarily keep autoInstallPeers: true because that version does not declare vue-eslint-parser. Version 2 bundles it; after upgrading, set autoInstallPeers: false.

Version 2 is major because Node.js 20 is removed from the runtime contract and the canonical lint contours are now explicit. Compatibility aliases remain.

Git hooks

node node_modules/@swarmmachina/standards/git/setup-hooks.mjs

The installer follows Conventional Commits and never overwrites existing hooks.

Verification and release

pnpm install --frozen-lockfile
pnpm run verify
pnpm pack --dry-run

Fixtures install the tarball in clean JS, TS7, TS-lint and Vue projects on Node 22 and 24, with automatic peer installation disabled.

Publishing is CI-only. After separate approval, a v* tag starts the release workflow, repeats the pnpm gate and runs npm publish --provenance. Local publish is forbidden.
