Fast, reliable, and secure dependency management.

--- **Fast:** Yarn caches every package it has downloaded, so it never needs to download the same package again. It also does almost everything concurrently to maximize resource utilization. This means even faster installs. **Reliable:** Using a detailed but concise lockfile format and a deterministic algorithm for install operations, Yarn is able to guarantee that any installation that works on one system will work exactly the same on another system. **Secure:** Yarn uses checksums to verify the integrity of every installed package before its code is executed. ## Features * **Offline Mode.** If you've installed a package before, then you can install it again without an internet connection. * **Deterministic.** The same dependencies will be installed in the same exact way on any machine, regardless of installation order. * **Network Performance.** Yarn efficiently queues requests and avoids request waterfalls in order to maximize network utilization. * **Network Resilience.** A single request that fails will not cause the entire installation to fail. Requests are automatically retried upon failure. * **Flat Mode.** Yarn resolves mismatched versions of dependencies to a single version to avoid creating duplicates. * **More emojis.** 🐈 ## Installing Yarn Read the [Installation Guide](https://yarnpkg.com/en/docs/install) on our website for detailed instructions on how to install Yarn. ## Using Yarn Read the [Usage Guide](https://yarnpkg.com/en/docs/usage) on our website for detailed instructions on how to use Yarn. ## Contributing to Yarn Contributions are always welcome, no matter how large or small. Substantial feature requests should be proposed as an [RFC](https://github.com/yarnpkg/rfcs). Before contributing, please read the [code of conduct](CODE_OF_CONDUCT.md).

Yarn has been inspired by the following projects: - [Bundler](https://github.com/bundler/bundler) - [Cargo](https://github.com/rust-lang/cargo) - [npm](https://github.com/npm/cli) ## Credits Thanks to [Sam Holmes](https://github.com/samholmes) for donating the npm package name!
