`rich-text-transforms`

This libary provides two functions, one that takes candyXML, and one that takes a string. Both return rich text as structured JSON. The structured JSON uses the format that Optimo have opted for, see (here)https://confluence.dev.bbc.co.uk/display/cps/Optimo+Client+Text+Blocks for more details.

Supported block types

The Optimo format consists of an array of nested ‘blocks’, where a block has a “type” (such as paragraph), and “model”. The model can contain fields such as ‘text’, attributes on that text - such as ‘bold’. The model can also contain an array of child blocks.

There are many types of block available.

Currently, this library only supports the following block types:

paragraph
text
urlLink
fragment

Installation in a FABL module

Add the following to the dependencies block in package.json:

{
  "@fabl/rich-text-transforms": "../../libraries/rich-text-transforms"
}

Usage

`candyXmlToRichText`

const { candyXmlToRichText } = require("@fabl/rich-text-transforms")

const xml = `
<body>

      <link>
        <caption>foo</caption>
        <url href="https://example.com/foo"/>
