Prettier is an opinionated code formatter that supports JavaScript, TypeScript, Flow, JSX, JSON, CSS, SCSS, Less, HTML, Vue, Angular, GraphQL, Markdown, and YAML. Current stable version is 2.x (latest 2.3.2), with a dev version 2.4.0-dev available. It enforces consistent style by parsing code and reprinting with its own rules, wrapping based on line length. Key differentiators: it eliminates debates over code style, has wide ecosystem support (editor integrations, pre-commit hooks, CI), and is extensible via plugins. Releases are frequent, and it is actively maintained by the Prettier community.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

prettier

✓ import prettier from 'prettier'

✗ const prettier = require('prettier')

Prettier is ESM-first since v2; for Node.js <12, use dynamic import or CJS require, but ESM is recommended.

format

✓ import { format } from 'prettier'

✗ import prettier from 'prettier'; prettier.format()

Named export since v2; default export is also available.

resolveConfig

✓ import { resolveConfig } from 'prettier'

✗ import { resolveConfig } from 'prettier/standalone'

resolveConfig is only available in node environment, not in standalone browser build.

Formats a simple JavaScript object string using Prettier with the babel parser.

import prettier from 'prettier'; const code = `const foo = { bar: 'baz' }`; const formatted = prettier.format(code, { parser: 'babel' }); console.log(formatted); // Output: // const foo = { bar: "baz" };

Debug

Known issues

breakingPrettier v2.0 changed default trailing comma from 'none' to 'es5' and other defaults. Upgrade may reformat code.

fix

Use --no-trailing-comma or set trailingComma: 'none' in config to revert.

affects: >=2.0.0

breakingPrettier v2.0 removed support for Node.js <10.13.0. Older Node versions will not work.

fix

Upgrade Node.js to >=10.13.0 or use Prettier v1.x.

affects: >=2.0.0

deprecatedThe --stdin flag is deprecated in v2; use --stdin-filepath instead.

fix

Replace --stdin with --stdin-filepath <filename>.

affects: >=2.0.0

gotchaUsing prettier.format() in a browser without proper parser may throw; use prettier/standalone bundle with plugins.

fix

Import from 'prettier/standalone' and register parser plugins.

affects: >=1.0.0

gotchaPrettier may reformat code differently than expected for JSX/TSX when using embedded language comments (e.g., ).

fix

Use // prettier-ignore for JS/TS, or <!-- prettier-ignore --> for HTML/JSX.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'prettier'

Prettier not installed or module resolution not configured.

fix

Run 'npm install prettier --save-dev' or ensure correct import path.

Error: No parser and no filepath given, couldn't infer a parser.

Calling prettier.format() without specifying parser and without filepath.

fix

Provide a parser option (e.g., parser: 'babel') or use prettier.check() with a filePath.

prettier is not a function

Using default import incorrectly when named import expected or vice versa.

fix

Use 'import prettier from "prettier"' for default, or 'import { format } from "prettier"' for named.

Cannot read property 'format' of undefined

Running prettier in a context where it's not loaded correctly (e.g., browser with wrong bundle).

fix

Use 'prettier/standalone' in browser environments and register plugins.
