What is this?

This package is a utility that takes nlcst nodes and gets their plain-text value.

When should I use this?

This is a small utility that is useful when you’re dealing with ASTs.

Install

This package is ESM only. In Node.js (version 14.14+ and 16.0+), install with npm:

npm install nlcst-to-string

In Deno with esm.sh:

import {toString} from 'https://esm.sh/nlcst-to-string@3'

In browsers with esm.sh:

<script type="module">
  import {toString} from 'https://esm.sh/nlcst-to-string@3?bundle'
</script>

Use

import {toString} from 'nlcst-to-string'

console.log(
  toString({
    type: 'WordNode',
    children: [
      {type: 'TextNode', value: 'AT'},
      {type: 'PunctuationNode', value: '&'},
      {type: 'TextNode', value: 'T'}
    ]
  })
) // => 'AT&T'

API

This package exports the identifier toString. There is no default export.

toString(value[, separator])

Get the text content of a node or list of nodes.

Prefers the node’s plain-text fields, otherwise serializes its children, and if the given value is an array, serialize the nodes in it.

Parameters

• node (Node or Array<Node>) — node to serialize.
• separator (string, default: '') — value to delimit each item

Returns

Result (string).

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 14.14+ and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.
