We have a variety of projects so they vary, but usually...
- ESLint for static analysis
- Coverage reports for unit tests - eg. Istanbul for Jasmine
- React projects use Flow type checking which again has coverage reports
- React projects use bundle analysis tools to work out which dependencies are adding the most download weight
- For performance and quality we use a mix of NewRelic and Calibre, but I'm not sure if that's the kind of thing you're thinking of.
The team has tried SonarQube in the past, which was good but didn't quite stick at the time; it's worth a look.
