Prettier 3 API format filepath resolveConfig ignore files CLI .prettierignore .gitignore documentation

💡 Result:

In Prettier 3, file handling via the API and CLI relies on specific mechanisms for configuration resolution and file ignoring. API Usage: The prettier.resolveConfig(fileUrlOrPath, options) function resolves configuration for a given file [1][2]. It searches for a configuration file starting from the provided file's directory and traversing up the file tree [1][3]. You can also provide an explicit configuration path via options.config [1][2]. To determine if a file is ignored by Prettier, use prettier.getFileInfo(fileUrlOrPath, options) [1][4]. This method returns an object containing an ignored boolean [1][2]. You can influence this check by passing options.ignorePath and options.withNodeModules [1][2]. CLI Behavior and Ignoring: By default, Prettier ignores files within version control directories (e.g.,.git,.svn,.hg) and node_modules [5][6]. Additionally, it automatically follows ignore rules defined in.gitignore and.prettierignore if they exist in the directory from which the CLI is run [5][6]. To customize ignored files via the CLI, you can use the --ignore-path option [7][8]. By default, Prettier searches for both.gitignore and.prettierignore [7][8]. Specifying --ignore-path overrides this default behavior [8][9]. To use multiple ignore files simultaneously (e.g., keeping the defaults while adding a custom one), you must explicitly list all of them: --ignore-path=.gitignore --ignore-path=.prettierignore --ignore-path=custom-ignore [7][8][9]. For one-off exclusions without modifying ignore files, you can use negative patterns directly in the command line (e.g., prettier. "!/*.{js,jsx,vue}" --write) [5][6].

Preserve Prettier CLI file handling.

findJsonFiles() uses only its local ignore list, while formatFiles() calls prettier.format() with fixed options and no filepath. This bypasses per-file configuration and .prettierignore rules, so matching files can be formatted or modified differently from the CLI. Resolve each file’s configuration and skip files reported as ignored, or document the intentional divergence.

In `@scripts/validation/validate-json.js` around lines 182 - 186, Update
formatFiles() to preserve Prettier CLI behavior by resolving configuration for
each file and passing its filepath to Prettier, then skip files identified as
ignored by the resolved configuration. Reuse the existing prettierOptions and
findJsonFiles() flow, and avoid formatting ignored files or bypassing per-file
settings.

Show affected filenames in read-only mode.

When --read-only detects formatting differences, Line [200] logs each filename only through log.debug. Without --verbose, users see only the count from Line [206] and cannot identify which files need changes. Log the filenames at normal output level or include them in the warning. Prettier's check modes are intended to identify files that differ. (prettier.io)

In `@scripts/validation/validate-json.js` at line 200, Update the
formatting-difference handling around log.debug so affected filenames are
emitted at the normal output level when --read-only is active, allowing users
without --verbose to identify each file while preserving the existing count
reporting.
