pnpm is a fast, disk space efficient package manager for Node.js. It was created to address some of the problems that npm and Yarn have, particularly around disk space usage and package duplication. With pnpm, packages are shared between projects, which means that you don't need to download and install the same package multiple times. This not only saves disk space but also speeds up installation times.
- Faster installation times
One of the biggest advantages of pnpm over npm and Yarn is its installation speed. Because packages are shared between projects, pnpm only needs to install each package once, which means that subsequent installations are much faster. This can be particularly useful if you're working on a large project with lots of dependencies.
- Reduced disk space usage
As mentioned earlier, pnpm only downloads each package once and then shares it between projects. This means that you can save a significant amount of disk space, especially if you're working on multiple projects that use the same packages.
- Multiple versions of the same package
Another useful feature of pnpm is its ability to support multiple versions of the same package. This can be particularly useful if you're working on a project that requires specific versions of packages or if you need to test different versions of a package.
- Easy migration from npm or Yarn
If you're already using npm or Yarn, migrating to pnpm is relatively easy. pnpm uses the same package.json file as npm and Yarn, so you don't need to make any significant changes to your project. You can simply install pnpm globally and then use it in place of npm or Yarn.
- Community support
While pnpm is a relatively new package manager, it has a growing community of users and contributors. There are a number of plugins and integrations available for pnpm, including support for popular build tools like webpack and rollup.
