wasm-opt: Optimize a file for size.
$ wasm-opt -Oz ${input-wasm} -o ${output-wasm}
try on your machine
The command "wasm-opt -Oz ${input-wasm} -o ${output-wasm}" is using the "wasm-opt" tool to optimize a WebAssembly module.
Here's a breakdown of each part of the command:
- "wasm-opt": This is the command to invoke the "wasm-opt" tool. The tool is typically used to optimize WebAssembly modules by applying various transformations and optimizations.
- "-Oz": This flag specifies the optimization level to be used. In this case, "-Oz" indicates that the tool should perform aggressive optimizations to minimize the output size of the WebAssembly module. The "z" flag stands for "optimize for size".
- "${input-wasm}": This is a placeholder for the input WebAssembly module file. The actual filename should be provided when running the command. It could be something like "input.wasm".
- "-o": This flag is used to specify the path and filename for the output WebAssembly module file that will be generated.
- "${output-wasm}": This is a placeholder for the output WebAssembly module file. The actual filename and path should be provided. It could be something like "output.wasm".
In summary, this command takes an input WebAssembly module, applies aggressive optimizations to minimize the output size, and generates a new optimized WebAssembly module as the output specified by the user.
