SonarLint plugin - JavaScript heap out of memory

[Pasor1 (Simone)]

PHPStorm with SonarLint Plugin, it works with php files, but trying to analyze any typescript file in my Angular project (a large one) I always have this error:

Hi @Pasor1, welcome to the community

The log shows Node.js is running out of memory at around 4gb (which is the default for your Node.js version), apparently this project needs more. This is independent from JVM memory limits and settings.

Node.js has limited heap memory by default. Assuming you have enough memory in the machine, you need to tell the scanner to allocate more memory in this case.

The scanner provides a parameter to allow more memory use via sonar.javascript.node.maxspace:

You can use sonar.javascript.node.maxspace property to allow the analysis to use more memory. Set this property to 4096 or 8192 for big projects. This property should be set in sonar-project.properties file or on command line for scanner (with -Dsonar.javascript.node.maxspace=4096).

Perhaps this can help or there is something else going on.

Hi @gab, it seems @Pasor1 is encountering the problem in SonarLint, not in the SonarQube scanner.

So @Pasor1 you can try setting the same property, but in SonarLint settings:

It is likely you will need to restart PHPStorm after setting this property. Let us know if that solves your issue.

Thanks gab for the welcome, and thanks Julien for the solution, it works like a charm!

@Pasor1 would you mind sharing the approximate size of your project (LOC, number of files, number of commits)?

It’s a very large multirepo Angular project. The main repo has about 4000 .ts files (130 Mb). We use ESLint also, and it needs the same node memory allocation to works properly.
