Svelte compiler implemented in Rust. Aims for 100% compatibility with the official Svelte compiler.

Architecture

Pipeline: Parse → Analyze → Transform

• svelte-ast: AST type definitions, ESTree serialization
• svelte-parser: Zero-copy parsing with OXC allocator, winnow-based template/CSS parser, OXC for JS/TS expressions
• svelte-analyzer: Semantic analysis (scope, bindings, validation)
• svelte-transformer: Code generation (JS/CSS output)
