babel-prettier-parser

library0.10.8jsnpmunverified

A Prettier parser wrapper that enables formatting of JavaScript/TypeScript code containing experimental or non-standard syntaxes that Babel can transform, such as pipeline operators, decorators, and do expressions. Version 0.10.8 is the latest stable release with no fixed release cadence. It ships TypeScript types and requires Prettier ^2.2.1 as a peer dependency. Unlike Prettier's default Babel parser, this package allows parsing of code with Babel plugins that are not included by default in Prettier, making it suitable for projects using advanced ECMAScript proposals. However, it is a niche tool with limited community adoption and may have compatibility issues with future Prettier versions.

Verified usage

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

parse

✓ import { parse } from 'babel-prettier-parser'

✗ const { parse } = require('babel-prettier-parser')

ESM-only since v0.10.0; TypeScript types included.

default

✓ import bpParser from 'babel-prettier-parser'; bpParser.parse(source)

✗ import { default as parse } from 'babel-prettier-parser'

Default export is an object with parse method; named export `parse` is preferred.

BABEL_PARSER_OPTIONS

✓ import { BABEL_PARSER_OPTIONS } from 'babel-prettier-parser'

✗ import BABEL_PARSER_OPTIONS from 'babel-prettier-parser'

Named constant for passing options to Babel; not a default export.

Demonstrates configuring Prettier to use babel-prettier-parser for formatting code with do expressions.

import prettier from 'prettier'; import { parse } from 'babel-prettier-parser'; const code = `const x = do { if (true) 1; else 2; };`; // Register the parser with Prettier prettier.format(code, { parser: 'babel', plugins: [{ parsers: { babel: { parse: (text, parsers) => { const ast = parse(text, { plugins: ['doExpressions'], sourceType: 'module', }); // Transform AST to Prettier-compatible AST if needed return ast; }, }, }, }], }).then(result => console.log(result));

Debug

Known issues

breakingVersion 0.8.0: parse now returns an object with a `type` property. Old code expects an AST node.

fix

Access the root node via result.ast or similar; check the updated API.

affects: >=0.8.0

deprecatedThe `text` parameter in parse has been deprecated in favor of `code`.

fix

Use { code: source } instead of { text: source }.

affects: >=0.9.0

gotchaThe parser does not support all Prettier options; custom Babel plugins must be passed explicitly.

fix

Always pass the required Babel plugins in the options object to parse.

affects: all

Errors

Common errors & fixes

Cannot find module 'babel-prettier-parser'

Package not installed or missed in dependencies.

fix

Run npm install babel-prettier-parser --save-dev

Must use import to load ES Module: require() of ES modules is not supported

CJS require not supported for ESM-only package.

fix

Use import syntax or dynamic import().

TypeError: parse is not a function

Default import is an object, not a function.

fix

Use { parse } instead of default import.
