What is monorepo?

A monorepo is a centralized repository that stores all the code for multiple projects in one place. This approach to code management can have several benefits, including improved collaboration between teams and individuals, increased code reuse and reduced duplication, and easier management of dependencies and versioning. By having all the code in one place, developers can make changes to the codebase more easily and with more confidence, knowing that any changes will be visible to all other members of the team.

Why Lerna?

Lerna is a popular open-source tool that can help manage a monorepo. It provides features like versioning, publishing, and linking packages together, making it easier to manage multiple projects within a single repository. The benefits of using Lerna include faster builds and development, better control over versioning and releases, and improved reliability and consistency.
