wasm-fibo

Calculates the fibonacci number of n : Fn

How to

Build the docker image that contains all the tools to build wasm binaries :

$ docker build . -t wasm

Run this docker image by providing the project as volume

$ docker run -it --rm -v $PWD:/project wasm:latest

Run the make commands that you want to build conventional binaries:

$ make compile-cpp # to compile only fibo.cpp to fibo_cpp.exe
$ make compile-rust # to compile only fibo.rs to fibo_rust.exe
$ make compile # to do both previous commands at once

Run the make commands that you want to build Webassembly binaries:

$ make wasm-cpp # to compile only fibo.cpp to fibo_cpp.wasm
$ make wasm-rust # to compile only fibo.rs to fibo_rust.wasm
$ make wasm # to do both previous commands at once

The make clean command will remove all binaries.

Run the wasm file by using node:

node fibo_cpp.js 10
