I run over Bitbucket Cloud pipelines the analyses of different apps which include big libraries, specifically, JavaScript libraries. After checking the analysed files listed in the “Code” tab of the SonarCloud web GUI I can see some of those big files are missing. Files with less than 20.000 lines are listed, files with more lines are not.
I have read somewhere that minified JavaScript files are excluded by default, but in this case the ignored files are not minified.
I didn’t find anything in the documentation specific for JS files (JavaScript/TypeScript/CSS | SonarCloud Docs), maybe it’s an overall exclusion rule for all types of files.
