Go Library

At Grab, we rely heavily on a large Go monorepo for backend development, which offers benefits like code reusability and discoverability. However, as we continue to grow, managing a large monorepo brings about its own set of unique challenges.



As an example, using Go commands such as go get and go list can be incredibly slow when fetching Go modules residing in a large multi-module repository. This sluggishness takes a toll on developer productivity, burdens our Continuous Integration (CI) systems, and strains our Version Control System host (VCS), GitLab.



In this blog post, we look at how Athens, a Go module proxy, helps to improve the overall developer experience of engineers working with a large Go monorepo at Grab.
