wasm-opt

Optimize WebAssembly binary files. More information: https://github.com/webassembly/binaryen.

• Apply default optimizations and write to a given file:
  wasm-opt -O {{input.wasm}} -o {{output.wasm}}
• Apply all optimizations and write to a given file (takes more time, but generates optimal code):
  wasm-opt -O4 {{input.wasm}} -o {{output.wasm}}
• Optimize a file for size:
  wasm-opt -Oz {{input.wasm}} -o {{output.wasm}}
• Print the textual representation of the binary to console:
  wasm-opt {{input.wasm}} --print
