library0.3.2jsnpmunverified

WASM-grate is a development tool that analyzes JavaScript and TypeScript codebases to identify functions and modules that are good candidates for migration to WebAssembly. It currently supports function declarations, expressions, and arrow functions, assigning a complexity score to help prioritize optimization efforts. The latest version is 0.3.2, and the project is in early development (pre-1.0.0) with a CLI for scanning files or directories. It is designed for front-end performance workflows, differentiating from generic profilers by focusing specifically on WebAssembly migration opportunities. Release cadence is irregular as it is still evolving.

Known issues

gotchaWASM-grate is pre-1.0.0 and not production-ready. Output may be incomplete or inaccurate.

fix

Wait for version 1.0.0 or test thoroughly before relying on results.

affects: <=0.3.2

deprecatedThe --path flag is used, but some documentation shows -path (single hyphen). Always use --path or -p.

fix

Use --path <path> or -p <path>.

affects: >=0.0.0

Errors

Common errors & fixes

ERROR: Could not read file: /path/to/file

Invalid path or permissions.

fix

Ensure the path exists and is readable: ls -la /path/to/file

Error: Unsupported syntax at line X

WASM-grate only supports function declarations, expressions, and arrow functions.

fix

Check if the file contains class methods or generator functions; those are not analyzed.
