wasm-server-runner
Allows you to run programs in the browser using web assembly using a simple cargo run.
Usage
Step 1.
rustup target add wasm32-unknown-unknown
cargo install wasm-server-runner
Step 2.
Add this to your ~/.cargo/config.toml (not the Cargo.toml of your project!):
[target.wasm32-unknown-unknown]
runner = "wasm-server-runner"
Step 3.
Run programs in the browser using
cargo run --target wasm32-unknown-unknown
cargo run --target wasm32-unknown-unknown --example example
wasm-server-runner path/to/file.wasm
Example output:
INFO wasm_server_runner: wasm output is 49.79kb large
INFO wasm_server_runner: starting webserver at http://127.0.0.1:1334
The website will reload when the server is restarted and serve files relative to the current directory.
Configuration options
All configuration options can be specified via environment variables.
WASM_SERVER_RUNNER_ADDRESS
Default: 127.0.0.1
Control the address that the server listens on. Set to 0.0.0.0 to allow access from anywhere.
WASM_SERVER_RUNNER_DIRECTORY
Default: .
Can be used to specify where relative path requests are loaded from.
WASM_SERVER_RUNNER_CUSTOM_INDEX_HTML
Default: none
When set, will try to load the custom index.html from that path instead of the
default. Can be relative to the directory.
Note: To support both module and non-module style the index.html needs to have specific string that will be replaced at runtime. The body should contain something like
{{ NO_MODULE }}
<script type="module">
// {{ MODULE }}
</script>
WASM_SERVER_RUNNER_HTTPS
Default: false
Controls whether https is used.
WASM_SERVER_RUNNER_NO_MODULE
Default: false
Controls whether the wasm-bindgen output uses modules or not.
