ncc vs Sucrase

ncc is a free, MIT-licensed command-line tool for compiling a Node.js module and its dependencies into one file. It is distributed through npm as `@vercel/ncc`, with `npm i -g @vercel/ncc` given as the global installation command. The project targets publishing minimal npm packages and sending only relevant application code to serverless environments. Its design goals include zero configuration, built-in TypeScript support, and handling Node.js programs and npm modules. Inputs can include TypeScript, binary addons, and dynamic requires. Build options cover minification, source maps, watched builds, external modules, and ECMAScript target selection. Node.js programs can call ncc programmatically with options for caching, externals, minification, source maps, and asset builds. `.ts` and `.tsx` inputs require a `tsconfig.json`. Module-format behavior includes automatic ES module output for `.mjs` files and `.js` files inside a `type: module` package boundary. Support examples cover Sequelize with MariaDB and `@google-cloud/vision` with `google-proto-files`. Dynamically loaded assets that static analysis cannot identify may not work correctly. It runs on Linux.
