Description: Yarn link is a command that allows you to create a symbolic link of a package in your project. This command is part of Yarn, a package manager that simplifies the installation, updating, and management of dependencies in JavaScript projects. By using ‘link’, developers can bind a local package to their project, enabling them to work on that package’s development without needing to publish it to a registry. This is particularly useful for testing and development, as it allows for changes to be made to the package and see immediate results in the project that uses it. Additionally, the use of symbolic links helps maintain a cleaner and more organized development environment, avoiding code duplication and facilitating collaboration between different projects that depend on the same package. In summary, Yarn’s ‘link’ command is a powerful tool for developers looking to optimize their workflow and improve efficiency in managing local dependencies.
