babel-parser-minimal

@babel/parser minimal bundle

This is a minimal build of @babel/parser, with most of the non-standard/proposal features stripped out. It is heavily minified and any unused code is attempted to be removed. It should work exactly the same as @babel/parser (except for unsupported plugins), and any case where it emits different output is a bug.

It includes support for TypeScript and JSX, as well as standardized modern features. It does not support most proposals.

Supported plugins:

• functionSent
• estree
• classProperties
• classPrivateProperties
• classPrivateMethods
• moduleStringNames
• topLevelAwait
• jsx
• typescript

Unsupported plugins:

• placeholders
• flow
• decorators
• v8intrinsic
• importAssertions
• moduleAttributes
• flowComments
• privateIn
• recordAndTuple
• functionBind
• pipelineOperator
• throwExpressions
• doExpressions
• partialApplication
• decimal
• classStaticBlock
• decorators-legacy
• exportDefaultFrom

Install

npm i -D babel-parser-minimal

API

The API is exactly the same as https://babeljs.io/docs/en/babel-parser#api, but if you attempt to use any unsupported plugin, it will throw an error.

Example

import { parse } from 'babel-parser-minimal'

// TS source code
const input = 'const foo: string = "bar"'
const ast = parse(input, { plugins: ['typescript'] })
