Yarn (Install)


Package test results are passing.

This package was approved as a trusted package on 7/12/2019.

Yarn is a package manager for the npm and bower registries with a few specific focuses.


Determinism: Based around a version lockfile which ensures that operations on the dependency graph can be easily transitioned. We check module directories and verify their integrity to ensure Yarn install always produces the same file structure.

Security: Strict guarantees are placed around package installation. You have control over whether lifecycle scripts are executed for packages and package hashes are stored in the lockfile to ensure you get the same package each time.

Performance: We're always performing operations such as package resolving and fetching in parallel. This ensures little idle time and maximum resource utilization.


This package requires NodeJS. You can install via either the nodejs or nodejs-lts package if you do not have it installed already.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
