wasm-opt

1. wasm-opt is a command line tool used for optimizing WebAssembly modules.
2. It is part of the WebAssembly Binary Toolkit (wabt), which is a suite of tools for working with WebAssembly.
3. The main purpose of wasm-opt is to reduce the size of WebAssembly modules while maintaining their functionality.
4. It achieves this by applying various optimization techniques that eliminate redundancy and improve the overall efficiency.
5. wasm-opt can perform a wide range of optimizations including function inlining, dead code elimination, constant folding, and more.
6. It can also remove debugging information and other unnecessary metadata from the WebAssembly module, further reducing its size.
7. The tool supports both binary and textual formats of WebAssembly, allowing optimization of modules in either format.
8. wasm-opt provides several command line options to specify the desired optimizations and control the level of optimization.
9. The optimized WebAssembly module produced by wasm-opt can be directly executed by a WebAssembly runtime environment, resulting in faster loading times and improved performance.
10. Developers typically integrate wasm-opt into their build pipelines to automatically optimize WebAssembly modules before deployment, ensuring efficient and optimized execution.
