but how should I specific a dir ?

Or just, what is the equivalent to npx eslint ./src ?
npx esw ./src says "No files matching the pattern "./src" were found."

What file types are you trying to lint?

.ts and .tsx. I worked it out as esw -w -c ./.eslintrc.json --ext .ts,.tsx './src/'
But eslint never asked that.
