How to setup IntelliJ when working on SDK

The monorepo setup is quite challenging for IntelliJ IDEs. The size of the monorepo combined with Rush symlinking can lead to very poor performance and excessively long indexing times.

Here are couple of hints to achieve optimal setup:

  • Increase max heap to at least 4GB

    • Go to Help > Edit Custom VM Options
    • Add/replace -Xmx setting to at least -Xmx4096m

  • Mark the following directories as Excluded - this may be time-consuming:

    • common/temp
    • All dist directories in all packages (in both libs and tools)
    • All esm directories in all packages (in libs)
    • If IntelliJ does not automatically exclude node_modules, then mark them as excludes as well

Refactoring

Automated code refactorings such as 'Rename file' can take a long time when touching files with common names as index.ts or util.ts. The IDE could get stuck for minutes or crash while running out of heap space. The best approach is to setup scopes:

  • Open Settings

  • Find Scopes

  • Create a new scope say libs and tools with the following value:

    file[gooddata-ui-sdk]:libs//*||file[gooddata-ui-sdk]:tools//*
