Key Features of the Site

Speed

Yarn caches every package it downloads so it never needs to download it again, and parallelizes operations to maximize resource utilization.

Security

Yarn uses checksums to verify the integrity of every installed package before its code is executed.

Reliability

Yarn uses a detailed, concise lockfile format and a deterministic algorithm for installs to ensure that an install that works on one system will work exactly the same way on any other system.

Workspaces

Yarn supports splitting your project into sub-components kept within a single repository.

Plug'n'Play

Yarn can install packages without needing to write files to disk, which can significantly speed up the installation process.

Offline Mode

If you've installed a package before, you can install it again without an internet connection.

Deterministic

The same dependencies will be installed the same exact way across every machine regardless of installation order.

Network Resilience

A single request failing won't cause an install to fail. Requests are retried upon failure.

Flat Mode

Resolves mismatched versions of dependencies to a single version to avoid creating duplicates.
