Wow, pnpm, You’re Really Fast
- pnpm is a package manager that saves users space and reduces build time by handling package storage differently from npm and Yarn.
- When you install a package, pnpm keeps it in a global store on your machine then creates a hard link from it instead of copying, so that there is only ever one copy of a module kept on disk.
- This approach saves gigabytes of disk space and provides a leaner, faster way to manage packages, which makes it ideal for a streamlined deployment environment like Heroku.
- Since May 2024, pnpm is now available in Heroku via Corepack.
- To get started with pnpm on Heroku, users can enable and use it with corepack after creating a new project folder.
- Comparing common commands, the usage for pnpm is fairly similar to that of npm or Yarn and should be intuitive.
- Users can install dependencies, build, prune devDependencies, and cache build with pnpm, which significantly speeds up build time compared to npm.
- In our test, the initial build with npm using the timing buildpack took 16 seconds, while that of pnpm only took 7 seconds.
- Through its storage approach, pnpm frees up substantial disk space, reduces build time in subsequent builds, and provides a faster way to manage packages, making it an attractive package manager for developers to consider.
- Moreover, with its support for Heroku, it offers a seamless path to deployment in the cloud.
