render-vendor

render-vendor is the fastest way to render HTML documents to PDFs

(or PNGs, JPEGs, BMPs...)

The Renderer loads HTML templates into Pages, which are later rendered into the desired format. With render-vendor, you can:

  • Generate PDFs in 10s of milliseconds (10-100x faster than several popular solutions);
  • Handle jobs asynchronously;
  • Swap internal components, e.g. Headless Chrome vs. PhantomJS; and
  • Integrate easily into modern JS build pipelines (e.g. React, Glimmer, Vue). For Ember + Electron projects, consider using ember-render-vendor

Quickstart

Installation:

Install via yarn or npm:

yarn add render-vendor
npm install render-vendor

Usage:

Open the Node.js REPL (i.e. type node in your working directory from above), then run the following:

const { Renderer } = require('render-vendor');

Renderer.load('https://isleofcode.com').then((page) => {
  return page.render('./out.pdf');
}).catch((err) => {
  console.error(err);
}).then(() => {
  Renderer.destroy();
}).then(() => {
  process.exit();
});

The process should exit automatically, and your directory should have a shiny new out.pdf!

⚠ BE CAREFUL: the default Renderer boots a parallel PhantomJS process. It is not bound to your REPL / application's lifecycle. Make sure to destroy() any Renderers you create.

ember-render-vendor

Are you building an Ember.js + Electron app? Check out ember-render-vendor, a companion lib that: uses the Broccoli build pipeline to:

  • Synchronizes data between your main application and rendered Page objects; and
  • Uses the Broccoli build pipeline to make writing parallel renderers as simple as writing components.

Credits

render-vendor is maintained by Isle of Code in Toronto. Initial release was sponsored by Common Sort.

Thanks also to @marcbachmann & contributors to node-html-pdf, from which the PhantomRender's internal render() implementation was lovingly aped.

👶 New to Node.js:

Assuming you've installed Node.js, try the following:

  • cd into a working directory (or mkdir a new one);
  • Run npm init and follow the prompts to create your first package.json; then
  • Run the npm install command above: npm install render-vendor.
