What Is Javascript Monorepo Tools?
A Javascript monorepo tool is a software tool that helps developers manage a monorepo, which is a single repository that contains multiple packages or modules. Monorepos are popular in large-scale projects as they allow for better code sharing, easier refactoring, and simpler dependency management. However, managing a monorepo can be complex, which is where monorepo tools come in.
Monorepo tools provide a range of features to simplify the development process in monorepos. For example, they can handle dependencies between packages, run tests, build and publish packages, and manage versions. They can also provide workspace isolation to allow developers to work on specific packages without affecting others.
A monorepo is a single repository containing multiple distinct projects, with well-defined relationships.
– Fast local computation caching
– Fast local task orchestration
– Fast-distributed computation caching
– Fast-distributed task execution
– Fast transparent remote execution
– Fast-detecting affected projects/packages
– Understandable workspace analysis
– Understandable dependency graph visualization

Why Use Javascript Monorepo Tools?
There are two major advantages to using a monorepo for a large-scale codebase. First of all, shared packages can be used in multiple applications on a local machine without an online registry (e.g. npm). The developer experience improves tremendously here because everything is in the same codebase without updating dependencies via third parties. When a shared package gets updated, it gets immediately reflected in all applications which depend on it.
Second, it improves collaboration across codebases. Teams working on different projects can improve the codebases of other teams without working on multiple repositories. It also improves accessibility without worrying about different setups and introduces more flexible ownership of the source code across teams. Another benefit is the refactoring of code across many Javascript projects.
Overall, monorepo tools are essential for managing large-scale Javascript projects with multiple packages or modules. They simplify the development process, increase productivity, and make it easier to maintain and scale monorepos over time. It is highly recommended to use Javascript build tools as well.
– Maintain branch hygiene
– Keep branches small, consider adopting trunk-based development
– Use pinned dependencies for every project
– Upgrade dependencies all at once, forcing every project to keep up with the dependencies.
Benefits of The Monorepo Approach:
Monorepo architecture has several benefits such as:
- Easy visibility
- Code sharing
- Improved collaboration
- Standardization
- Discoverability
- Release management
- Easier refactoring
There are several monorepo tools for Javascript among which we have covered RushJS, Turborepo, Yarn Workspace, Yalc, NPM Workspace, Lerna & PNPM. As per the State of JS 2022 survey, Yarn Workspaces, NPM 7 Workspaces & Lerna are the top favorites in terms of use. Although, PNPM & Turborepo are gaining popularity over time.
Now, let’s check these tools in detail..!!

Well, workspace is a general term that means the set of features in the npm cli that provides support to managing multiple packages from your local files system from within a singular top-level, root package.
PNPM
PNPM workspace is another JavaScript monorepo management tool that is built on top of the pnpm package manager. It provides a unified workspace for managing multiple packages within a single repository. With the PNPM workspace, you can install dependencies and run scripts across all packages in a workspace with a single command.
One of the main advantages of the PNPM workspace is its efficient use of disk space and memory. Rather than installing packages for each package separately, pnpm shares packages between packages, reducing the amount of disk space and memory needed.
