Writing and executing your Rust program as WebAssembly (Wasm) in under 5 minutes.
This demonstration was performed using both Ubuntu Linux OS and Google’s Chrome Web Browser. Other combinations have not been tested.
Step 1 — Install Apache2 and Rust
Run all of the following Ubuntu system set up commands (update, install Apache2 and Rust)
Step 2 — Create a new Rust project
Create a quick Rust project
Step 3 — Configure Rust for Wasm
Configure rust by adding this config to the lib section of the ~/triple/Cargo.toml file
Step 4 — Specify the build target
Finish configuring Rust by creating a new file at `~/.cargo.config` and adding the following config to it
Step 5 — Write Rust
Write a quick Rust program and save it as triple.rs (in the `~/triple/src` directory)
Step 6 — Build the Wasm code
Build the Rust code into Wasm and then copy the Wasm file to the Apache2 web server area
Step 7 — Use this HTML
Create a new file called triple.html in the var/www/html/ directory and fill it with the following code.
Step 8 — Execute your Rust code via a mouse click
Visit your machine’s IP at the triple HTML page i.e. http://12.345.456.78/triple.html
Then click the “Triple the number” button.
The following alert will be shown.
