Lerna vs pnpm: What are the differences?

Introduction

In this article, we will compare Lerna and pnpm to understand their key differences.

Installation and Package Management: Lerna is a tool for managing JavaScript projects with multiple packages, while pnpm is a package manager for JavaScript projects. Lerna helps with managing the versioning and dependency linking of packages within a project, while pnpm provides a fast and efficient package installation and management system.
Monorepo Support: Lerna is primarily focused on managing monorepos, where multiple packages are stored in a single repository. It allows for versioning, releasing, and managing the inter-package dependencies within a monorepo. On the other hand, pnpm supports both monorepos and single-package projects. It offers efficient disk space utilization by storing dependencies in a single global store, regardless of the number of projects.
Dependency Deduplication: Lerna does not have built-in dependency deduplication. Each package in the monorepo can have its own set of dependencies, resulting in possible duplication of dependencies across packages. On the contrary, pnpm implements dependency deduplication, where common dependencies are shared across projects, reducing the disk space usage.
Concurrency and Speed: Lerna operates sequentially when running commands or scripts across multiple packages. This can lead to slower execution times, especially in larger monorepo projects. In contrast, pnpm takes advantage of parallel execution, enabling faster installation and performance by leveraging parallelization.
Offline Support: Lerna does not provide built-in offline support for package installation. It requires an internet connection to download and install packages. On the other hand, pnpm has offline support, allowing developers to install packages even without an internet connection. It caches the downloaded packages locally, facilitating offline installations and ensuring consistent builds.
Integration and Ecosystem: Lerna integrates well with other tools commonly used in the JavaScript ecosystem, such as npm, Yarn, and Babel. It can work alongside these tools to provide a comprehensive package management solution. pnpm, on the other hand, is designed as an alternative to npm and Yarn, providing its own package management system while being compatible with the npm ecosystem.

In summary, Lerna is primarily focused on managing monorepos and offers versioning and dependency linking, whereas pnpm provides efficient package installation, dependency deduplication, parallel execution, offline support, and compatibility with the npm ecosystem.

Detailed Comparison

Lerna	pnpm
It is a popular and widely used package written in JavaScript. It optimizes the workflow around managing multi-package repositories with git and npm.	It uses hard links and symlinks to save one version of a module only ever once on a disk. When using npm or Yarn for example, if you have 100 projects using the same version of lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be saved in a single place on the disk and a hard link will put it into the node_modules where it should be installed.
-	Fast. As fast as npm and Yarn; Efficient. One version of a package is saved only ever once on a disk; Great for multi-package repositories (a.k.a. monorepos); See the recursive commands; Strict. A package can access only dependencies that are specified in its package.json; Deterministic. Has a lockfile called pnpm-lock.yaml; Works everywhere. Works on Windows, Linux and OS X; Aliases. Install different versions of the same package or import it using a different name.

What are some alternatives to Lerna, pnpm?

Meteor

A Meteor application is a mix of JavaScript that runs inside a client web browser, JavaScript that runs on the Meteor server inside a Node.js container, and all the supporting HTML fragments, CSS rules, and static assets.

Bower

Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat.

Elm

Writing HTML apps is super easy with elm-lang/html. Not only does it render extremely fast, it also quietly guides you towards well-architected code.

Underscore

A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

Julia

Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library.

Deno

It is a secure runtime for JavaScript and TypeScript built with V8, Rust, and Tokio.

Racket

It is a general-purpose, multi-paradigm programming language based on the Scheme dialect of Lisp. It is designed to be a platform for programming language design and implementation. It is also used for scripting, computer science education, and research.

Chart.js

Visualize your data in 6 different ways. Each of them animated, with a load of customisation options and interactivity extensions.

PureScript

A small strongly typed programming language with expressive types that compiles to JavaScript, written in and inspired by Haskell.

Immutable.js

Immutable provides Persistent Immutable List, Stack, Map, OrderedMap, Set, OrderedSet and Record. They are highly efficient on modern JavaScript VMs by using structural sharing via hash maps tries and vector tries as popularized by Clojure and Scala, minimizing the need to copy or cache data.
