How to print ESLint progress as it runs, but not everything at once when all files are processed?

Question

When running ESLint, nothing is print out until the whole process is done. How can I see the progress as it processed different files, instead of waiting until everything is done?

Answer 1

On my mind, --debug output is too spammy, try to reduce it:

# eslint ./src & ./config folders with printing the processed files
DEBUG=eslint:cli-engine yarn eslint ./{src,config}

# OR:
# for NPM or other dependency manager
# eslint ./src & ./config folders with printing the processed files
DEBUG=eslint:cli-engine eslint ./{src,config}

As a result, you will have a list of files that processed by CLI.

Answer 2

Use debug option will print out the progress:

npx eslint . --debug

Edit after @Oleksandr Kucherenko suggestion to see a more concise result: DEBUG=eslint:cli-engine eslint .
