Hi @queen-of-code,
welcome to our community.
Regarding SonarJS, we’re currently working on replacing our “homemade” parser with a community-based one espree (the one used by ESLint).
As we didn’t complete the full migration, we try first to parse with espree parser: if we have a parse error, we log an error message and we fallback to our “homemade” parser.
If I’m not wrong decorators are still at stage 2, so they’re not considered standard JS syntax (hence espree doesn’t support them).
However, despite having those parse errors logged, your analysis should still be successful at the end. Could you please confirm if that’s the case?
