Synckit enables synchronous execution of asynchronous functions in Node.js. Leveraging worker threads, it bypasses the single-threaded limitations of JavaScript. This is useful for integrating asynchronous code into synchronous workflows or interacting with libraries lacking synchronous alternatives. Synckit simplifies wrapping asynchronous calls, providing a clean and efficient way to improve performance when synchronous behavior is necessary. This improves the user experience of tools that often need to wrap libraries like esbuild in CLIs.
