However, you can bypass all these issues and still get access to the npm registry by using Yarn. Additionally, it is a future-ready package manager with robust features and simple commands. Continue reading as we show you how to install yarn packages on your Windows PC from scratch.
What Is Yarn?
Find below the novel features of Yarn that make it an extraordinary tool for every developer:
- It fetches and installs JS libraries, tools, packages, etc., faster.
- Its core engine ensures integrity, reliability, and version control of installed packages.
- A simple software development project can include thousands of dependencies. Yarn makes dependency management workflow effortless.
- It supports mixing registries.
- Yarn is compatible with Bower and npm workflows.
- It offers installed module license restrictions.
- Comes with a public JS API for consumption of API data via build tools.
- Yarn also offers beautiful CLI outputs, minimal code lines, and a readable user interface.
This future-ready package manager has a somewhat similar or more straightforward process for DevOps package management. However, the Yarn tool is highly reliable, faster, and extremely secure when compared with Yarn alternatives.
What Does Yarn Do?
Yarn simply solves common package management problems that npm suffers. The followings are some popular functionalities of Yarn:
- Yarn supports plugins. Users can use Yarn plugins, third-party plugins for Yarn, or write their own plugins.
- The Constraints functionality enables developers to enforce rules and policies for manifest fields or dependencies across scoped workspaces.
- Yarn lets a programmer use an offline cache on the local machine using a single file.
- The Plug’n’Play option lets users run Node.js projects minus the node_modules folder. The resultant Node.js application starts faster when compared with apps that contain the node_modules folder.
- The Protocols functionality enables developers to define the protocol for package resolution. For instance, you will be using the patch protocol to create a patched version of the original package. Another example could be the git protocol to fetch public packages from any Git repository.
- The Release Workflow option helps a software developer automatically upgrade relative packages distributed in several monorepos. For this, a programmer needs to upgrade the root packages and Release Workflow handles the rest.
- Yarn Workspaces is an intuitive functionality. It allows programmers to install dependencies all in one go from multiple package.json files in many subfolders of a single root package.json file.
The Yarn Workflow
Whenever you switch from one package manager to another, the main challenge is the change of workflow. Facebook’s goal was to create a package manager that will be easy to use while supporting the existing standard workflows from popular package repos like npm. Hence, Yarn did not make any drastic changes. Here is a snapshot of the basic workflow of Yarn:
- Create or start a new app development project:
- Adding, removing, or updating various dependencies:
yarn add [package],
yarn upgrade [package],
yarn remove [package].
- Installing or reinstalling a code library or dependency:
yarn install --force, etc.
- Managing versions of packages being created, updated, patched, etc., using Gits.
- Integrating with related tools continuously like AppVeyor, CirleCI, Codeship, Semaphore, Codefresh, etc.
The Benefits of Yarn
- Yarn’s core engine comes with powerful algorithms to allow faster installation of packages. When you fetch and install thousands of packages in your software project, Yarn installs them in parallel. On contrary, npm does this one by one. Hence, the project time frame increases drastically.
- Yarn allows the developers to maintain several local cache files for multiple projects. Hence, using or updating numerous packages for multiple app development projects becomes easy and faster.
- Tech giants like Facebook, Google, etc., support the Yarn community. Hence, you can find the latest patches, upgrades, and new releases frequently.
- Yarn guarantees baseline installation throughout all systems via the deterministic manner of installing operations and a lock file format.
- Yarn ensures the integrity of all the imported packages by running checksums.
- Yarn avoids request waterfalls when getting packages from cloud sources. This process increases network efficiency.
