FAQs
What is SWC?
SWC is a fast compiler for JavaScript and TypeScript written in Rust. It is often used as a drop-in replacement for Babel in build tools such as Next.js and Vite.
Where do I put the .swcrc file?
Place it in your project root. SWC picks up the configuration automatically when it runs.
What is the difference between the TypeScript and ECMAScript parsers?
The TypeScript parser understands type annotations and TSX, while the ECMAScript parser is for plain JavaScript and JSX. Choose the one that matches your source files.
Do I need an account to use this tool?
No. Like every tool on ToolsFreeHub, the SWC Config Generator is free and works without signing up.
