Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install micromark-factory-mdx-expression

In Deno with esm.sh:

import {factoryMdxExpression} from 'https://esm.sh/micromark-factory-mdx-expression@1'

In browsers with esm.sh:

<script type="module">
  import {factoryMdxExpression} from 'https://esm.sh/micromark-factory-mdx-expression@1?bundle'
</script>

Use

import {ok as assert} from 'uvu/assert'
import {factoryMdxExpression} from 'micromark-factory-mdx-expression'
import {codes} from 'micromark-util-symbol/codes'

// A micromark tokenizer that uses the factory:
/** @type {Tokenizer} */
function tokenizeFlowExpression(effects, ok, nok) {
  return start

  // …

  /** @type {State} */
  function start(code) {
    assert(code === codes.leftCurlyBrace, 'expected `{`')
    return factoryMdxExpression.call(
      self,
      effects,
      factorySpace(effects, after, types.whitespace),
      'mdxFlowExpression',
      'mdxFlowExpressionMarker',
      'mdxFlowExpressionChunk',
      acorn,
      acornOptions,
      addResult,
      spread,
      allowEmpty
    )(code)
  }

  // …
}

API

This module exports the identifier factoryMdxExpression. There is no default export.

The export map supports the development condition. Run node --conditions development module.js to get instrumented dev code. Without this condition, production code is loaded.

factoryMdxExpression(…)

Parameters

• effects (Effects) — context
• ok (State) — state switched to when successful
• type (string) — token type for whole ({})
• markerType (string) — token type for the markers ({, })
• chunkType (string) — token type for the value (1)
• acorn (Acorn) — object with acorn.parse and acorn.parseExpressionAt
• acornOptions (AcornOptions) — configuration for acorn
• boolean (addResult, default: false) — add estree to token
• boolean (spread, default: false) — support a spread ({...a}) only
• boolean (allowEmpty, default: false) — support an empty expression
• boolean (allowLazy, default: false) — support lazy continuation of an expression

Returns

State.

Types

This package is fully typed with TypeScript. It exports the additional types Acorn and AcornOptions.

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 16+. Our projects sometimes work with older versions, but this is not guaranteed.

These extensions work with micromark version 3+.

Security

This package is safe.
