Technical Principles and Concepts
4.1. Explanation of basic concepts
4.1.1 Introduction to Yarn
Yarn is a Git-based package management tool that makes it easy to manage project dependencies.
4.1.2 Package Management
Yarn provides a package manager that makes it easy to add, upgrade, and publish dependencies. Through the package manager, we can ensure that all dependencies of the project are up to date, and load dependencies on demand, thereby improving the construction speed and operation efficiency of the project.
4.1.3 Build and Deploy
Yarn provides a series of tools, such as environmental assessment, testing, command line tools, etc., for building and deploying applications. With these tools, we can quickly build, test and deploy applications, ensuring high-availability deployments.
