wasm-fibo

Calculates the fibonacci number of n : Fn.

The purpose of this repo is to dive in Web Assembly and Wasmer. The implementation of this fibo is in C++ and not optimized (no multi-threading).

How to build Web Assembly

Pre-requisite

1. Install emscripten by following the instructions of emscripten.org

Or

1. Use a Docker image like this one:

docker run -it --name wasm --rm -v $PWD:/src robertaboukhalil/emsdk:1.38.26 bash

Build

After you installed emscripten you should be able to build the .wasm file:

make wasm

Test

After the compilation, you can test the wasm binary file by typing the following command line:

node target/fibo.js 11 # should display "F(11) = 144"

How to run from Wasmer

Pre-requisite

1. Build Web Assembly
2. Install wasmer by following the instructions of wasmer.io

Run

Just run it with wasmer:

wasmer run target/fibo.wasm 11 # should display "F(11) = 144"

How to publish to wapm.io

Pre-requisite

1. Build Web Assembly
2. Install wasmer by following the instructions of wasmer.io

Publish

After you installed wasmer and built the .wasm file you should be able to publish it as a package after you logged in:

wapm login
wapm publish

How to run from WAPM

Pre-requisite

1. Install wasmer by following the instructions of wasmer.io

Run

Just install the wasm package lhauspie/fibo from wapm and then run it:

wapm install -g lhauspie/fibo
fibo 11 # should display "F(11) = 144"
