Yarn is a fast, reliable and secure dependency management tool. Compared with npm, yarn has many advantages, the main advantages are: high speed, offline mode, version control.

Advantages of yarn

1. High speed

Npm waits for one package to be fully installed before skipping to the next, but yarn executes the package in parallel, so it's much faster. On the Internet, there are a lot of npm and yarn installation rely as much on the execution speed, yarn has obvious advantages in terms of speed. Experience the same flying speed in the actual project, who knows who has tried it?

2. Offline mode

The principle of offline is relatively simple, the installed package will be saved in the cache directory, and then the installation will be copied directly from the cache. The essence of doing so will still improve the speed of installation and download and avoid unnecessary network requests.

3. Version control

One of the stronger pain points of npm is that version control is not accurate enough when the dependency level of the package is deep. Yarn is inherently version-hardened. A npm-shrinkwrap.json-like yarn.lock file is generated that describes the version number of the package itself and locks the version numbers of all packages it depends on.
