svelte-compiler

svelte-compiler provides the public compiler surface for working with Svelte in Rust.

It supports:

• parsing Svelte components into the public AST
• printing modern AST nodes back to source
• compiling components into JavaScript and CSS artifacts
• compiling rune-enabled modules
• preprocessing source with custom hooks
• best-effort source migration helpers

Install

[dependencies]
svelte-compiler = "0.1.1"

Example

use svelte_compiler::{CompileOptions, compile};

let result = compile(
    "<script>let name = 'world';</script><h1>Hello {name}</h1>",
    CompileOptions::default(),
)?;

assert!(result.js.code.contains("Hello"));
# Ok::<(), svelte_compiler::CompileError>(())

Main APIs

• compile compiles a .svelte component
• compile_module compiles a rune-enabled JavaScript or TypeScript module
• parse parses a component into the public AST
• print and print_modern turn AST nodes back into Svelte source
• preprocess runs one or more preprocessors over source text
• migrate performs a best-effort migration to modern Svelte syntax
