Packem
A fast and modern bundler for Node.js and TypeScript. Supports multiple runtimes, shared modules, server components, dynamic import, wasm, css, and more.Built on top of Rollup, combined with your preferred transformer like esbuild, swc, or sucrase.Tree Shaking
Packem supports tree-shaking both ES modules and CommonJS out of the box. It statically analyzes imports and exports, removing everything unused — even across dynamic import() boundaries and CSS modules.Minification
Includes minifiers for JavaScript, CSS, HTML, and SVG out of the box. Runpackem build --production and your application is built and optimized automatically.Libraries
Build libraries for multiple targets at once — modern ES module, legacy CommonJS, and TypeScript definitions all from one source. Just configure your package.json and Packem handles the rest.Transformer
Supports different transformers for your source code:esbuild, swc, sucrase, oxc, and custom transformers.Pail
Highly configurable Logger for Node.js, Edge and Browser. Hackable and configurable to the core, pail can be used for logging, status reporting, and output rendering.Effortless Logging, Minimal Syntax
Get started instantly with Pail's intuitive design. Whether you're debugging or tracking processes, the minimal syntax ensures your focus stays on coding, not configuration.More Than Just Logs
Leverage built-in timers, stack traces, error formatting, spam prevention by throttling logs, secrets filtering, and object interpolation to gain deeper insights.Blazing Fast on Any Platform
Built for browsers and servers, Pail ensures lightning-fast performance and compatibility. Spam prevention and circular structure handling simplify even the most complex applications.Your Logs, Your Way
Choose between human-readable Pretty outputs or structured JSON for machine parsing. Integrates filename, timestamp, and metadata effortlessly.Cerebro
A CLI framework that lets you build awesome command-line tools in Node.js and TypeScript. Create CLIs with a few flags or advanced CLIs with subcommands.Flag and Argument Parsing
Custom flag parser built from years of experimentation — flexible enough for easy, predictable UX without compromising type safety for the developer.Auto-documentation
Pass--help to any CLI command for automatically generated help, flag options, and argument information.TypeScript (or not)
Written in TypeScript with a CLI generator that builds both fully configured TypeScript or plain JavaScript CLIs. Cleaner syntax in TypeScript, but everything works in either language.Autocomplete
Terminal autocompletion with the--autocomplete flag. Users complete command and flag names by pressing tab.Define, design, deploy what's next for the web
Proudly OpenSource.
