Say I want to use this rule:
https://eslint.org/docs/rules/no-debugger
however, I have about 15 files where I want to keep debugger; statements.
Is there something I can add at the top of the .ts/.js files, that can tell ESLint to ignore the no-debugger rule for this particular file?
You can also disable ESLint in the same line:
debugger; // eslint-disable-line no-debugger 
console.debug and console.error and I used this: // eslint-disable-next-line no-console on the line above the statements.You can do that like this:
/* eslint-disable no-debugger */ ... code that violates rule ... /* eslint-enable no-debugger */ Update your eslint configuration file (.eslintrc etc) with such rule:
"rules": { "no-debugger":"off" } 
Probably your IDE can help. If you are using VS Code, you can mouse over debugger, click Quick Fix..., and select Disable no-debugger for the entire file, as shown as below:
Then the IDE will add the following comment at the top of the file to disable the rule for you:
/* eslint-disable no-debugger */ See more on the eslint no-debugger rule.
OR, add:
"no-debugger": false to the bottom of tslint.json, to disable this warning for all files.
I think debugger need to removed, and briefly used in a development environment.
So you're better off ignoring it where you use.
For example: disable no-debugger for this line
// eslint-disable-next-line no-debugger debugger or disable no-debugger for the entire file
/* eslint-disable no-debugger */
