# ls-engines <sup>[![Version Badge][npm-version-svg]][package-url]</sup> [![github actions][actions-image]][actions-url] [![coverage][codecov-image]][codecov-url] [![dependency status][deps-svg]][deps-url] [![dev dependency status][dev-deps-svg]][dev-deps-url] [![License][license-image]][license-url] [![Downloads][downloads-image]][downloads-url] [![npm badge][npm-badge-png]][package-url] Determine if your dependency graph's stated "engines" criteria is met. ## Example ```console > ls-engines `package.json` found; building ideal tree from package.json... Valid node version range: ^14 || ^13 || ^12 || ^11 || ^10 || ^9 || ^8 || ^7 || ^6 || ^5 || ^4 || ^0.12 || ^0.11 || ^0.10 || ^0.9 || ^0.8 Currently available, most recent, valid node major versions: v14.2, v13.14, v12.16.3, v11.15, v10.20.1, v9.11.2, v8.17, v7.10.1, v6.17.1, v5.12, v4.9.1, v0.12.18, v0.11.16, v0.10.48, v0.9.12, v0.8.28 Current node version, v13.7.0, is valid! ``` `ls-engines` takes a `--mode` option, which defaults to "auto", but can also be "actual", "virtual", or "ideal". ”actual“ reads from `node_modules`; ”virtual“ reads from a lockfile; “ideal” reads from `package.json`.
