ipynb2html is a converter (renderer) of the Jupyter Notebook Format 4.0+ to static HTML. It works both in Node.js and browser environment.
Packages
This repository contains the following packages, all published on npm.
ipynb2html-core
This package provides the converter itself and some utilities with no dependencies. You have to provide your own syntax highlighter and Markdown, math and ANSI sequences renderer; or not, if you don’t need them.
ipynb2html
This package builds on the ipynb2html-core and provides a complete, ready-to-go renderer configured with:
-
marked as Markdown renderer,
-
KaTeX as math renderer,
-
anser as ANSI sequences renderer,
-
highlight.js as syntax highlighter.
It also provides a reference stylesheet which you can find in
dist/notebook.min.css (or non-minified
styles/notebook.css).
ipynb2html-cli
This package provides a CLI interface for ipynb2html.
Usage
CLI
ipynb2html notebook.ipynb notebook.html
Run ipynb2html --help for more information.
Node.js (server-side)
To render HTML in Node.js (server-side rendering), you need some (fake) DOM implementation. The recommended one is nodom — it’s lightweight, small, doesn’t have any external dependencies and ipynb2html is tested against it. However, you can choose any other if you like.
npm install ipynb2html nodom
import * as fs from 'fs'
import * as ipynb from 'ipynb2html'
import { Document } from 'nodom'
const renderNotebook = ipynb.createRenderer(new Document())
const notebook = JSON.parse(fs.readFileSync('./example.ipynb', 'utf8'))
console.log(renderNotebook(notebook).outerHTML)Browser (client-side)
You have basically two options how to use ipynb2html in the browser: use the browser bundles provided in the ipynb2html package, or build your own bundle (using e.g. Rollup or webpack).
The provided bundles are in UMD format (AMD, CommonJS and IIFE in one file), so they should work in all environments (old and modern browsers, Node.js). They are transpiled and have injected core-js polyfills to be compatible with browsers that have >0.5% global coverage, Firefox ESR, and not dead browsers.
Full Bundle
ipynb2html-full.min.js is a self-contained bundle with all the
external dependencies included (marked, KaTeX, Anser and Highlight.js).
You can link it from jsDelivr CDN, for example:
<!DOCTYPE html>

</html>The bundle exposes global variable ipynb2html:
const element = ipynb2html.render(notebook)
document.body.appendChild(element)ipynb2html also provides function autoRender that renders each
notebook on the page embedded (as JSON) inside
<script type="application/x-ipynb+json">...</script>.[1]

<html>Slim Bundle
ipynb2html.min.js contains only ipynb2html and ipynb2html-core code
(plus polyfills). If you load marked, KaTeX, AnsiUp, and Highlight.js in
the page, you will get the same functionality as with
ipynb2html-full.min.js:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.3/dist/katex.min.css" crossorigin="anonymous">
<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.7.3/build/styles/default.min.css" crossorigin="anonymous">
<script src="https://cdn.jsdelivr.net/npm/marked@4.1.1/marked.min.js" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/ansi_up@5.0.1/ansi_up.js" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.7.3/build/highlight.min.js" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/katex@0.16.3/dist/katex.min.js" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/ipynb2html@0.4.0-rc.1/dist/ipynb2html.min.js" crossorigin="anonymous"></script>
</head>
...
</html>Or you may use any other implementations and provide them to the
ipynb2html.createRenderer function. All of them are optional, but you
usually need at least a Markdown renderer.
