Is there a way to prevent Prettier from automatically inserting parentheses for a single argument in an arrow function?

Currently, I've integrated Prettier into my workflow, but I've encountered an issue with arrow functions in JavaScript. For example:

arg => console.log(arg)

However, Prettier automatically formats it as:

(arg) => console.log(arg)

This formatting adjustment isn't to my liking. Is there a way to disable this behavior?

Answer №1

To customize the configuration settings, you have the option to edit either your .prettierrc file or prettier.config.js file.

For the .prettierrc file:

{
  "arrowParens": "avoid"
}

For the prettier.config.js file:

module.exports = {
  arrowParens: "avoid"
};

By adding these lines, you can ensure that prettier will no longer automatically add parenthesis for arrow functions.
