@H-R-30 Sorry I forgot to follow up on this topic, but the conclusion is incorrect. I’ve used the solution I proposed extensively, it is tested and working and certainly not half. .eslintrc is the ESlint configuration file, which a Google Search would have given you as a first result. Here is an example. Naturally, if you don’t define any options, eslint won’t know what to look for.
If eslint is not recognized, it means you haven’t told Windows to look in node_modules\.bin to find executables. So change the command to cmd /k node_modules\.bin\eslint --fix-dry-run $(FULL_CURRENT_PATH). Or edit the Windows PATH variable and add node_modules\.bin\eslint to it if it is not there. For globally installed npm executables add %AppData%\npm\node_modules\.bin too. Restart Notepad++ to be sure the changes are in effect.
