Boost Your CI/CD Efficiency with pnpm

In the world of modern software development, Continuous Integration and Continuous Deployment (CI/CD) have become essential practices. They allow teams to rapidly deliver high-quality software while maintaining a streamlined development pipeline. One critical aspect of CI/CD is package management, and in this article, we will explore the benefits of using pnpm over the traditional npm install command. Let's dive in and discover why pnpm is a game-changer for your CI/CD workflows.

If you’ve read this far, you’re probably a DeployBot user and familiar with version control systems, CI/CD, and other related topics. If not, we’ve compiled several beginner’s guides: Laravel, Digital Ocean, Ruby on Rails, Docker, Craft CMS, Ghost CMS, Google Web Starter Kit, Grunt or Gulp, Slack, Python, Heroku and many more.

Faster Installations

When it comes to installing dependencies, pnpm takes a unique approach. Unlike npm, pnpm uses a shared package store, which means that if multiple projects use the same package, it is only downloaded once. This greatly reduces duplication and speeds up the installation process. In CI/CD pipelines, where speed is crucial, pnpm's ability to cache packages provides a significant advantage. With pnpm, you can save precious build time by avoiding repetitive downloads of identical dependencies across multiple jobs or stages.

Reduced Disk Space Usage

As software projects grow in complexity, so does the size of their dependencies. Over time, the node_modules folder can become bloated and consume a substantial amount of disk space. However, pnpm uses a unique approach called a "virtual store," where it stores dependencies in a global cache and creates symlinks to them instead of physically copying them. This approach dramatically reduces the disk space requirements for your projects. By leveraging pnpm, you can free up valuable storage resources on your CI/CD infrastructure and keep your pipelines running smoothly.

Improved Security

Security is a critical concern for any software development team. With pnpm, you can benefit from its security features that help safeguard your projects. pnpm enforces a content-addressable storage system, ensuring that dependencies cannot be tampered with or modified. Additionally, by using a shared package store, pnpm reduces the risk of downloading malicious packages from external sources. These security enhancements make pnpm a reliable choice for CI/CD workflows, where ensuring the integrity and safety of your codebase is paramount.

Simplified Maintenance

Maintaining a large number of projects, each with its own set of dependencies, can be challenging. Updating packages across multiple projects can be time-consuming and error-prone. However, pnpm simplifies this process. With its unique approach to package management, pnpm makes it easier to update dependencies across all projects simultaneously. By centralizing package updates, you can ensure consistency and save time during maintenance tasks in your CI/CD pipelines.

Easy Integration

Integrating pnpm into your existing CI/CD workflows is straightforward. pnpm provides a command-line interface that is compatible with npm commands. This means you can seamlessly replace npm install with pnpm install in your build scripts without any major modifications. The transition from npm to pnpm is smooth, enabling teams to adopt pnpm without disrupting their current development processes.

pnpm vs npm

npm maintains a flattened dependency tree as of version 3. This leads to less disk space bloat, with a messy node_modules directory as a side effect.

On the other hand, pnpm manages node_modules by using hard linking and symbolic linking to a global on-disk content-addressable store. This nets you the benefits of far less disk space usage, while also keeping your node_modules clean. There is documentation on the store layout if you wish to learn more.

The good thing about pnpm's proper node_modules structure is that it "helps to avoid silly bugs" by making it impossible to use modules that are not specified in the project's package.json.

As CI/CD becomes an integral part of modern software development, optimizing package management is crucial. By leveraging pnpm instead of npm install, you can reap numerous benefits in your CI/CD workflows. Faster installations, reduced disk space usage, improved security, simplified maintenance, and seamless integration are some of the advantages that pnpm brings to the table. Embrace pnpm and unlock a more efficient and streamlined CI/CD experience for your development team.
