prettier --check . prints the list of files that would change and exits with status 1, which is the correct form for a CI gate. --write reformats in place and exits 0, so a pipeline that runs --write verifies nothing and may leave the repository dirty without failing. --list-different is the older equivalent of --check and prints paths without the summary line.
Prettier 2.8 added --cache, which stores metadata in node_modules/.cache/prettier and skips files whose content and options are unchanged. On a large repository this turns a multi-second check into a near-instant one. The cache key includes the resolved options, so changing .prettierrc invalidates it correctly.
In CI the cache only helps if the directory is restored between runs. Where that is not set up, scoping the check to changed files through the version control diff is usually the bigger win, and is what lint-staged does on the pre-commit path.
