Formatting Javascript/Typescript Code With Prettier

You’ve got a bunch of Typescript files with both .ts and.tsx. You need to format them using prettier. Your code is managed with source control so you can back out of the changes whenever you need to.

Here’s a quick command line invocation to do it:

npx prettier -w '**/*.ts' '**/*.tsx'

If there are any directories you’d like to ignore, list it in the arguments with a !:

npx prettier -w '**/*.ts' '**/*.tsx' '!src/gen/**'

I know the help includes the –ignore-path but this doesn’t actually ignore a path. Instead, it configures the “prettier ignore” file that’s used.
