# build Build-tool detectors for the JavaScript/TypeScript build ecosystem. Covers Webpack, Vite, Rollup, esbuild, Babel, SWC, and Parcel. Each tool exposes its `Detector` plus a `_CONFIG_PATTERNS` constant describing the config-file shapes it recognizes. [`detectBuildTools`](https://www.hyperfrontend.dev/docs/libraries/project-scope/tech/build/#api-detectBuildTools) runs all detectors and returns the aggregate `BuildToolDetection[]`. Detectors are unopinionated about preferred build tooling: they return what they find and at what confidence; consumers decide what to do with the results. --- Canonical page: https://www.hyperfrontend.dev/docs/libraries/project-scope/tech/build/ This file: https://www.hyperfrontend.dev/docs/libraries/project-scope/tech/build.md Documentation index: https://www.hyperfrontend.dev/llms.txt
