@iarna/rtf-to-html

Convert RTF to HTML in pure JavaScript.

const rtfToHTML = require('@iarna/rtf-to-html')

fs.createReadStream('example.rtf').pipe(rtfToHTML((err, html) => {
  // …
})
rtfToHTML.fromStream(fs.createReadStream('example.rtf'), (err, html) => {
  // …
})
rtfToHTML.fromString('{\\rtf1\\ansi\\b hi there\\b0}', (err, html) => {
  console.log(html)
  // prints a document containing:
  // <p><strong>hi there</strong></p>
})

This is built on rtf-parser and shares its limitations.

This generates complete HTML documents from RTF documents. It does not currently have the facility to work on snippets of either.

Supported features:

• Paragraph detection (results in <p> tags) plus empty paragraph trimming.
• Font (as font-family: Font Name, Font Family). Font families in RTF don't map perfectly to HTML. This is the mapping we currently use:
  • roman: serif
  • swiss: sans-serif
  • script: cursive
  • decor: fantasy
  • modern: sans-serif
  • tech: monospace
  • bidi: serif
• Font size (as font-size: #pt)
• Bold (as <strong>)
• Italic (as <em>)
• Underline (as <u>)
• Strikethrough (as <s>)
• Superscript (as <sup>)
• Subscript (as <sub>)
• Foreground color (as color: rgb(#,#,#))
• Background color (as color: rgb(#,#,#))
• Paragraph first-line indents (as text-indent: #pt)
• Idented regions (as padding-left: #pt)
• Text alignment: left, right, center, justify (as text-align:)
