- This notebook provides the reader with a demo that uses a Julia package called WebAssembly.jl to generate a .wasm file and call it on your device.
- We'll assume you've installed Julia
- Install LiveServer.jl via
$ julia

julia> using Pkg; Pkg.add("LiveServer")- Run web server
$ julia -q # You can omit logo with -q option.
julia> using LiveServer
julia> serve()
✓ LiveServer listening on http://localhost:8000/ ...
(use CTRL+C to shut down)
- Finally open your web browser e.g. Google Chrome and access to
localhost:8000.
- Install WebAssembly.jl (master branch required) and IRTools.jl
$ julia
julia> ENV["PYTHON"]=Sys.which("python3")
julia> using Pkg
julia> pkg"add WebAssembly#master"
julia> Pkg.add(["IRTools", "PyCall"])- Note that we've installed PyCall.jl for convenience to run wasm file locally.
To run wasm file locally, install wasmer from PyPI in advance via
$ pip3 install wasmer$ pip3 install jupyter jupytext
$ julia
julia> ENV["JUPYTER"]=Sys.which("jupyter")
julia> using Pkg
julia> Pkg.add("IJulia")
julia> using IJulia
julia> installkernel("Julia")$ julia
