Monorepo
Monorepo
A development approach where multiple programs and codebases are managed together in a single location.
In Simple Terms
A monorepo is a system where multiple programs that would otherwise be scattered are all managed together in one large file storage location. For example, if you store code for a mobile app and a website in the same place, you can roll out design changes to both at once. This reduces the effort of making changes that span multiple projects, which is why large-scale development teams at companies like Google have adopted it.
Behind the Name
Monorepo combines 'mono,' meaning one, with 'repository,' a storage space for code. True to its name, it refers to managing multiple projects together in one large shared location — a shortened form of Mono-Repository.
Take a Closer Look!
A monorepo is a method of managing the source code of multiple different projects and applications together in a single large repository.
To put it simply, think of it like stuffing all your programs into one giant drawer. Normally, you'd create separate storage spaces for each app, but with a monorepo, you deliberately bring them all together in one place.
The biggest advantage of this approach is that it makes it easier to share code components across projects.
For example, if you fix a login system or a shared calculation rule in one place, those changes can be efficiently reflected across all the apps that use those components — cutting down on the effort of updating multiple separate repositories.
That said, as the amount of code grows, the overall system can become sluggish.
With too many files, finding specific content can get difficult, and you may need dedicated management tools. Even so, keeping code visible to the entire team and streamlining collaboration makes it a widely adopted approach in large-scale software development.
