  First-party npm packages published by Salesforce for the Lightning Web Components
  open-source framework. LWC is distributed exclusively through npm — there is no
  HTTP API client library, because LWC is a browser/server JavaScript UI runtime rather
  than a hosted service. Versions and publish dates below were read from the npm
  registry metadata endpoint (registry.npmjs.org) on 2026-08-27.

      Legacy LWC project scaffolder. DECAY SIGNAL — last published 2021-10-08, nearly five years
      before the current framework release (lwc 9.4.1, 2026-08-12). lwc.dev now documents
      `npm init lwr` instead. Recorded here as evidence, not as a recommended install path.

notes:

  - >-
    Two first-party scaffolders (create-lwc-app, lwc-services) have not been published since 2021 while
    the framework itself ships monthly. The live scaffolding path is `npm init lwr`.
