Monorepo is a strategy for managing the source code of a project, where all code is stored in the same repository (Repository), rather than scattered across multiple repositories. This strategy is especially useful for large enterprises and large projects because it makes it easier to share and reuse code across projects.
In Angular application development, we may encounter the need to develop multiple closely related Angular applications. These applications may have many common components, services or other code. If we create a separate repo for each application, we may run into problems when we need to share code between applications. We need to copy the code, or create a shared library. This can lead to code duplication, or make it difficult to update and maintain shared code.
And if we use the Monorepo strategy, we can put all the applications and shared code in the same repo. This way, when we need to share code between applications, we only need to reference it from the same repo. This avoids code duplication and makes it easier to update and maintain shared code.
Here is an example of developing an Angular application using the Monorepo strategy:
Let's say we're developing a large enterprise application that consists of multiple sub-applications, each of which is an Angular application. These sub-applications have many common components and services, such as navigation bar, user authentication service, etc.
If we create a separate repo for each sub-app, then we need to duplicate the code for the navigation bar and user authentication service in each repo. This way, when we need to update these common codes, we need to update them separately in each repo. This is tedious and error prone.
And if we use the Monorepo strategy, we can put all sub-applications and common code in the same repo. Our directory structure might look like this:
/my-monorepo
/apps
/app1
/app2
/app3
/libs
/navbar
/auth-service
In this structure, /appseach subdirectory under the directory is an Angular application, and /libseach subdirectory under the directory is a piece of code that can be shared between applications. When we need to update the code of the navigation bar or user authentication service, we only need to update it in one place. All sub-apps are automatically updated.
This example illustrates the advantages of using the Monorepo strategy in Angular application development. Monorepo strategy can make code reuse, update and maintenance easier. Especially when developing large-scale enterprise applications, the Monorepo strategy can significantly improve development efficiency.
