library1.2.2jsnpmunverified

Prettier is an opinionated code formatter that supports JavaScript, TypeScript, CSS, HTML, GraphQL, Markdown, and more. Current stable version is 3.x (npm package name 'prettier', not 'prettier-resolver'). Prettier is actively maintained with frequent releases. It differs from other formatters by being opinionated (few options), rewriting entire AST, and integrating into editors, pre-commit hooks, and CI. Available as CLI and API; ships as ESM-only since v3, requires Node >=18.

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 * as prettier from 'prettier'

✗ import prettier from 'prettier'

Use namespace import for all exports; no default export since v3.

format

✓ import { format } from 'prettier'

✗ const { format } = require('prettier')

Named exports available; CommonJS require not supported in v3.

resolveConfig

✓ import { resolveConfig } from 'prettier'

Works with ESM; config resolution is async.

prettier (CLI)

✓ npx prettier --write .

✗ prettier --write .

CLI is invoked via npx or global install; path-based execution is common.

PrettierOptions

✓ import type { Options } from 'prettier'

✗ import { Options } from 'prettier'

Use type import for TypeScript options; Options type exists since v2.

Demonstrates using Prettier's format() API to format JavaScript code with custom options.

import { format } from 'prettier'; const code = `foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());`; const formatted = await format(code, { parser: 'babel', semi: true, singleQuote: true, tabWidth: 2, }); console.log(formatted);

Debug

Known issues

breakingPrettier v3 drops CommonJS support; require() will not work.

fix

Switch to ESM imports (import { format } from 'prettier') or use dynamic import().

affects: >=3.0.0

breakingNode.js >=18 required as of v3; older Node versions cause errors.

fix

Upgrade Node.js to version 18 or later.

affects: >=3.0.0

gotchaFormatting with 'resolveConfig' returns null if no config found; must handle null case.

fix

Use `const config = (await resolveConfig(filePath)) ?? {};` to avoid undefined errors.

affects: >=2.0.0

deprecatedThe '--no-semi' CLI flag is deprecated in favor of '--semi false'.

fix

Use '--semi false' instead of '--no-semi'.

affects: >=2.3.0

gotchaUsing prettier-plugin-svelte or prettier-plugin-tailwindcss may conflict with each other; order matters.

fix

List plugins in order of application (e.g., prettier-plugin-svelte first).

affects: >=2.0.0

Errors

Common errors & fixes

Cannot find module 'prettier'

Prettier not installed or used via CommonJS in v3.

fix

Run `npm install prettier@latest` and use ESM import syntax.

TypeError: prettier.format is not a function

Incorrect import style; default import does not exist in v3.

fix

Use `import { format } from 'prettier'` instead of `import prettier from 'prettier'`.

Error: Cannot find module 'prettier/package.json'

Using older require() path that is removed in v3.

fix

Use `import { format } from 'prettier'` or update to v2 for CommonJS support.

Error: Couldn't resolve parser 'babel'. Plugins don't seem to be installed.

Missing parser plugin (e.g., @prettier/plugin-babel).

fix

Install parser: `npm install --save-dev @prettier/plugin-babel` and add to config.
