@cloudalgo/lwc-core

ESLint-free static analysis for Lightning Web Component and Aura JavaScript. Parses with @babel/parser and runs rule listeners over the AST — no ESLint runtime, so it bundles cleanly in Electron and other constrained hosts.

Usage

import { Linter, allRules } from "@cloudalgo/lwc-core";

const linter = new Linter(allRules);
const { violations } = linter.lint({ filePath: "myComponent.js", source });
// violations: [{ ruleId, message, severity, category, line, column }]

Disable specific rules per file:

linter.lint({ filePath, source, disabled: new Set(["no-async-operation"]) });

Rules

LWC-specific: no-inner-html, no-document-query, no-api-reassignments, no-leaky-event-listeners, valid-wire, valid-api, valid-track, no-deprecated, no-async-operation, no-unknown-wire-adapters.

Generic JS (also run on Aura): no-eval, no-implied-eval, no-new-func, no-script-url, no-debugger, eqeqeq.

Suppression

Line-level directives are honored (plugin prefixes are stripped, so directives written for the official @lwc/lwc/* plugin work too):

// eslint-disable-next-line no-async-operation
setTimeout(fn, 0);
doStuff(); // eslint-disable-line

Development

npm install     # install deps
npm run build   # tsc → dist/
npm test        # vitest run

Releases are tag-driven: npm run release -- patch|minor|major bumps the version, tags vX.Y.Z, and pushes; the publish workflow then builds, tests, and publishes to npm and cuts a GitHub Release from CHANGELOG.md. See CLAUDE.md for architecture.
