Before you start

Better resources are available than this site for installing these dependencies.

Below are a list of the dependencies, and a non-comprehensive instructions on how to get them onto your system.

Install Rust

If Rust isn’t already installed on your system, you should install it as per the rust-lang.org install instructions.

This will add cargo and rustup to your path, which are the main entry points into Rust.

Add the WASM specific targets

This command adds the backends for the Rust compiler to emit machine code for different Android architectures.

rustup target add \
    wasm32-unknown-unknown

Install wasm-bindgen

This cargo extension handles all the environment configuration needed for successfully building libraries for Android from a Rust codebase, with support for generating the correct jniLibs directory structure.

cargo install wasm-bindgen-cli

Install nodejs

If nodejs isn’t already installed on your system, you should install it as per the nodejs.org install instructions.

This guide and related documentation assumes yarn as a package manager.
