Functions
function check
check: (source: string, options?: Options) => Promise<boolean>;
check
checks to see if the file has been formatted with Prettier given those options and returns aBoolean
. This is similar to the--list-different
parameter in the CLI and is useful for running Prettier in CI scenarios.
function clearConfigCache
clearConfigCache: () => Promise<void>;
As you repeatedly call
resolveConfig
, the file system structure will be cached for performance. This function will clear the cache. Generally this is only needed for editor integrations that know that the file system has changed since the last format took place.
function format
format: (source: string, options?: Options) => Promise<string>;
format
is used to format text using Prettier. [Options](https://prettier.io/docs/en/options.html) may be provided to override the defaults.
function formatWithCursor
formatWithCursor: ( source: string, options: CursorOptions) => Promise<CursorResult>;
formatWithCursor
both formats the code, and translates a cursor position from unformatted code to formatted code. This is useful for editor integrations, to prevent the cursor from moving when code is formatted.The
cursorOffset
option should be provided, to specify where the cursor is.
function getFileInfo
getFileInfo: ( file: string | URL, options?: FileInfoOptions) => Promise<FileInfoResult>;
function getSupportInfo
getSupportInfo: (options?: SupportInfoOptions) => Promise<SupportInfo>;
Returns an object representing the parsers, languages and file types Prettier supports for the current version.
function resolveConfig
resolveConfig: ( fileUrlOrPath: string | URL, options?: ResolveConfigOptions) => Promise<Options | null>;
resolveConfig
can be used to resolve configuration for a given source file, passing its path or url as the first argument. The config search will start at the directory of the file location and continue to search up the directory.A promise is returned which will resolve to:
- An options object, providing a [config file](https://prettier.io/docs/en/configuration.html) was found. -
null
, if no file was found.The promise will be rejected if there was an error parsing the configuration file.
function resolveConfigFile
resolveConfigFile: (fileUrlOrPath?: string | URL) => Promise<string | null>;
resolveConfigFile
can be used to find the path of the Prettier configuration file, that will be used when resolving the config (i.e. when callingresolveConfig
).A promise is returned which will resolve to:
- The path of the configuration file. -
null
, if no file was found.The promise will be rejected if there was an error parsing the configuration file.

Change when properties in objects are quoted. "as-needed"
property rangeEnd
rangeEnd: number;
Format only a segment of a file. Number.POSITIVE_INFINITY

rangeStart: number;
Format only a segment of a file. 0
property requirePragma

Prettier can restrict itself to only format files that contain a special comment, called a pragma, at the top of the file. This is very useful when gradually transitioning large, unformatted codebases to prettier. false
property semi
semi: boolean;
Print semicolons at the ends of statements. true
property singleAttributePerLine
singleAttributePerLine: boolean;
Enforce single attribute per line in HTML, Vue and JSX. false

trailingComma: 'none' | 'es5' | 'all';
Print trailing commas wherever possible. "all"

config?: string | undefined;
Pass directly the path of the config file if you don't wish to search for it.
property editorconfig
editorconfig?: boolean | undefined;
If set to
true
and an.editorconfig
file is in your project, Prettier will parse it and convert its properties to the corresponding prettier configuration. This configuration will be overridden by.prettierrc
, etc. Currently, the following EditorConfig properties are supported: - indent_style - indent_size/tab_width - max_line_length
property useCache
useCache?: boolean | undefined;
If set to
false
, all caching will be bypassed.
