Supports 'paths', 'jsxImportSource' and more from tsconfig.json files.Transpiles every file, so TypeScript and JSX just work.Both ESM and CommonJS are supported internally Bun uses ESM. Implements Node's node_modules resolution algorithm, so you can use npm packages in Bun.Implements Web APIs like fetch WebSocket and ReadableStream.The goal of Bun is to run most of the world's JavaScript outside of browsers, bringing performance and complexity enhancements to your future infrastructure, as well as developer productivity through better, simpler tooling. Bun natively implements hundreds of Node.js and Web APIs, including ~90% of Node-API functions (native modules), fs, path, Buffer and more. Use it to run your current JavaScript & TypeScript apps or scripts - on your local computer, server or on the edge. Bun is a complete toolkit for building JavaScript apps, including a bundler, transpiler, and package manager.īun is designed as a drop-in replacement for Node.js. Bun extends JavaScriptCore, the performance-minded JS engine built for Safari. In edge computing environments, reducing cold start times is critical.

Please take a look at the repository for more detail information.Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem, with three major design goals:

site-snapshotĪctually, this crawler is published in npm with name site-snapshot. The crawler just checks every page specifiedīy site.json so that we don’t need to worry about the infinite loop caused by the circular linkage between pages. The crawler visits all pages with depth first search algorithm.

If you want to call the crawling synchronously, you need to write await keyword in each call. Puppeteer APIs are basically called asynchronous manner.
