Overview
What Prettier is
Prettier parses supported code and reprints it using consistent formatting rules. It reduces style churn in an AI coding workflow and can integrate with an editor or automated check. Formatting is separate from linting, type checking, and behavioral testing.
For a first workflow, install or invoke the formatter version configured by the repository. Format the files relevant to the task without rewriting unrelated work. Confirm the result and run the project’s separate correctness checks.
