Run WebAssembly

Run on Browser​

Currently, there is no way to build JavaScript to WebAssembly for browsers.

Run Standalone​

Let's run JavaScript wasm standalone.
First, prepare wasm program built for standalone environment.
No html or javascript file needed.

  • prime.wasm : wasm file built for browsers

wasmtime​

wasmtime is standalone runtime for WebAssembly.
Executable file can be downloaded from github releases.

Command line options can be found at CLI Options for wasmtime.

This command invokes the entity function, or run().

invoke prime function with wasmtime
echo "100000" | wasmtime prime.wasm
output
given number = 100000
max prime = 99991
duration [ms] = 989
0

wasmer​

wasmer is also famous standalone runtime for WebAssembly.

Command line options can be found at CLI Usage. Executable files can be downloaded at github releases.
This command invokes the prime() function.

invoke prime function with wasmer
echo "100000" | wasmer run  prime.wasm
output
given number = 100000
max prime = 99991
