What’s inside?

Dumping all your code into a single shared mono-repository is all the rage these days driven by the desire to lessen the pain of “dependency hell” and version control conflicts. However, monorepos present challenges to project modeling, performance, and the user experience that modern developer tooling is only just beginning to address. 

Learn how large repositories (aka “Gigaprojects”) can threaten to break IDEs like IntelliJ IDEA. Discover the drawbacks of working with a monorepo and get some new ideas and approaches to solving these problems by looking at them through the DPE lens.

Summit Producer’s Highlight

Developers use an IDE to be more productive, using time-saving features like fast access to code, shortcuts, and plugins. Yet developer productivity is often compromised by deploying a large monorepo. Factors like high memory consumption, protracted indexing processes, and the need to manage large file systems and thousands of fine-grained modules, often cause your IDE to operate at a snail’s pace, if it doesn’t break down completely. 

Learn how the IntelliJ IDEA team is exploring DPE concepts to mitigate some of the major disadvantages of monorepo environments. Approaches discussed include reducing the working scope of the codebase, remote development practices to speed up the environment, and parallelizing work to a CI server with pre-generated indexes.
