I have installed prettier via
yarn add prettier
I would like prettier to only format typescript code (I am developing AWS CDK project, there is no src folder by convention & there could be typescript files here and there). In other words, I would like prettier to check all files in my project that has extension *.ts.
I checked its documentation for configuration. But there is no such option to specify file extension.
How can I run prettier for only *ts files then? Is it even possible? If not, what could be the workaround?
CodePudding user response：
To exclude files from formatting, create a .prettierignore file at the root of your project.
And to format only the *.ts files you should ignore everything but the *.ts files.
Example
# Ignore everything recursively
*
# But not the .ts files
!*.ts
# Check subdirectories too
!*/
In the code above, the * means to ignore everything including the subfolders, and the next line !*.ts tells the prettier to reverse the previous ignoring of the .ts files. The last line !*/ means to check the subdirectories too, but with the previous rule, it's only looking for the .ts files.
