Struct wasm_run::Hooks

pub struct Hooks {
    pub pre_build: Box<dyn Fn(&dyn BuildArgs, BuildProfile, &mut Command) -> Result<()> + Send + Sync>,

Hooks.

Check the code of Hooks::default() implementation to see what they do by default.

If you don’t provide your own hook, the default code will be executed. But if you do provide a hook, the code will be replaced.

Fields

pre_build: Box<dyn Fn(&dyn BuildArgs, BuildProfile, &mut Command) -> Result<()> + Send + Sync>

This hook will be run before the WASM is compiled. It does nothing by default. You can tweak the command-line arguments of the build command here or create additional files in the build directory.

post_build: Box<dyn Fn(&dyn BuildArgs, BuildProfile, String, Vec<u8>) -> Result<()> + Send + Sync>

This hook will be run after the WASM is compiled and optimized. By default it copies the static files to the build directory.

serve: Box<dyn Fn(&dyn ServeArgs, &mut Server<()>) -> Result<()> + Send + Sync>

This hook will be run before running the HTTP server. By default it will add routes to the files in the build directory.

watch: Box<dyn Fn(&dyn ServeArgs, &mut RecommendedWatcher) -> Result<()> + Send + Sync>

This hook will be run before starting to watch for changes in files. By default it will add all the src/ directories and Cargo.toml files of all the crates in the workspace plus the static/ directory if it exists in the frontend crate.

Trait Implementations
