legion-toolkit

One install for the whole toolkit behind LEGION-STANDARDS. Every tool is exposed as a subpath, so a repo never has to know the individual package names, and every tool added to the toolkit shows up here.

yarn add -D legion-toolkit oxlint prettier typescript

Installing runs nothing. A tool is on only where you reference it.

Lint (oxlint)

// .oxlintrc.json
{
  "jsPlugins": ["legion-toolkit/eslint-plugin"],
  "rules": { "legion/no-narrative-comments": "error" },
}

Or generate a full preset:

import { writeFileSync } from 'node:fs';
import { strict } from 'legion-toolkit/rules';

writeFileSync('.oxlintrc.json', JSON.stringify(strict.oxlint, null, 2));

Lint (ESLint)

import legion from 'legion-toolkit/eslint-plugin';

export default [...legion.configs.strict];

Prettier and TypeScript

// package.json
{ "prettier": "legion-toolkit/prettier" }

// tsconfig.json
{ "extends": "legion-toolkit/tsconfig/next.json" }

base.json, node.json, next.json, and react-native.json are available.

Audit

yarn legion-audit --md AUDIT.md --json audit.json
yarn legion-audit directives

The legion-audit command is provided by this package directly, so it works under Yarn, npm, and pnpm without relying on transitive bin linking.

Packages inside

| Subpath | Package | | ------------------------------ | ------------------------ | | legion-toolkit/eslint-plugin | eslint-plugin-legion | | legion-toolkit/rules | legion-rules | | legion-toolkit/audit | legion-audit | | legion-toolkit/prettier | legion-prettier-config | | legion-toolkit/tsconfig/* | legion-tsconfig |

Each is also published on its own for repos that want a smaller footprint.

Node 22 or newer. Peers (all optional): oxlint >= 1.53, eslint >= 9, prettier >= 3.
