yarnpkg - How to get a list of all eslint rules that errored during linting?

Question

I'm currently in the process of updating the eslint packages being used for a large codebase. After the update eslint is now finding errors on thousands of files that fail different rules.

Is there a way to run eslint and have it output a list of the rules that failed?

By default eslint runs through each file and outputs each line that failed. Instead I want to build a list of rules that failed (no duplicates) like below:

i.e.

no-console
react/no-multi-comp
react/jsx-curly-spacing

My intent is to turn all these failing rules off in the eslint.js file, but was hoping for an easy way to collate this list.

You need to use an eslint formater to do this. Here are a couple that you might consider
