hast-util-phrasing

What is hast-util-phrasing?

The `hast-util-phrasing` package is a utility for working with phrasing content in the HAST (Hypertext Abstract Syntax Tree) format. It helps in identifying and manipulating phrasing content, which includes text and elements that can be found within paragraphs.

What are hast-util-phrasing's main functionalities?

Check if a node is phrasing content

This feature allows you to check if a given node is considered phrasing content. In this example, a text node is checked and returns true.

const { isPhrasing } = require('hast-util-phrasing');
const node = { type: 'text', value: 'Hello, world!' };
console.log(isPhrasing(node)); // true

Filter phrasing content from a list of nodes

This feature allows you to filter out only the phrasing content from a list of nodes. In this example, only the text node is considered phrasing content and is included in the result.

const { isPhrasing } = require('hast-util-phrasing');
const nodes = [
  { type: 'text', value: 'Hello, world!' },
  { type: 'element', tagName: 'div', children: [] }
];
const phrasingNodes = nodes.filter(isPhrasing);
console.log(phrasingNodes); // [{ type: 'text', value: 'Hello, world!' }]

Other packages similar to hast-util-phrasing

unist-util-visit

The `unist-util-visit` package is used to recursively walk through a Unist syntax tree, which includes HAST. It allows you to visit nodes of a specific type and perform operations on them. While it doesn't specifically target phrasing content, it can be used to traverse and manipulate nodes in a similar way.

hast-util-to-string

The `hast-util-to-string` package is used to convert HAST nodes to plain text. It is useful for extracting text content from HAST trees, which can include phrasing content. However, it focuses on text extraction rather than identifying or filtering phrasing content.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install hast-util-phrasing

Use

import {phrasing} from 'hast-util-phrasing'

// Given flow content:
phrasing({
  type: 'element',
  tagName: 'div',
  children: [{type: 'text', value: 'Alpha'}]
})
// => false

// Given a phrasing element:
phrasing({
  type: 'element',
  tagName: 'meta',
  properties: {itemProp: 'bravo'},
  children: []
})
// => true

// Given a non-phrasing element:
phrasing({
  type: 'element',
  tagName: 'meta',
  properties: {charSet: 'utf8'},
  children: []
})
// => false

// Given text:
phrasing({type: 'text', value: 'Delta'})
// => true

API

This package exports the following identifiers: phrasing. There is no default export.

phrasing(node)

Returns

boolean — Whether node passes the test.

Security

hast-util-phrasing does not change the syntax tree so there are no openings for cross-site scripting (XSS) attacks.
