WebAssembly Feature Detection (Legacy)

verified May 27, 2026

This package, `webassembly-feature` (version 1.3.0), provides synchronous utilities to detect support for various WebAssembly features in the current JavaScript environment. Last updated over six years ago, it is considered abandoned. Its API exposes an object with methods like `supports['multi-value']()` that return boolean values directly. For new projects or those requiring up-to-date feature detection, the `wasm-feature-detect` package (maintained by GoogleChromeLabs) is the recommended alternative, as it offers a more comprehensive and asynchronous API reflecting modern WebAssembly standards and browser capabilities. This package's synchronous nature contrasts with the predominantly asynchronous WebAssembly APIs and feature detection patterns prevalent today.
