Sometime ago, I wrote a small module called node-html-to-image. It generates images from HTML in Node.js. For more information, here is an article that explains how to use it. This week, it has been featured in NodeWeekly 🎉

This week, I also released version 1.2. Let's see what's new in node-html-to-image.

✨ Transparency support

This feature was asked by jordan314. It wasn't possible to have a transparent background for png images. Here is an example to achieve it with the new transparent option:

const nodeHtmlToImage = require('node-html-to-image')

nodeHtmlToImage({
  output: './image.png',
  type: 'png',
  transparent: true,
  html: '<html><body>Hello world!</body></html>'
})
  .then(() => console.log('The image was created successfully!'))

📝 Improve documentation

Users frequently asked me two questions about node-html-to-image usage:

How to use locally stored images?
How to set my image resolution?

I added two sections directly in the README that answer these questions (image resolution and dealing with images).

I hope it will help 🙏

♻️ Simplify test setup

I use tesseract to test the module works fine. It was tricky to install the engine on your computer in order to run tests. I moved to tesseract.js which is a Javascript port of this OCR engine. Running yarn installation command is now enough to setup the project before running tests.

💻 The CLI has been released too!

node-html-to-image has its own CLI. I think it is a good way to quickly give a try to the module.

What's new in `node-html-to-image-cli` v1.1:

Add an option to provide content

It is now possible to use handlebars with the CLI too. Here is an example:

npx node-html-to-image-cli ./index.html ./image.png --content ./content.json

index.html:


<!DOCTYPE html>
<html>
  <body>
    <h1>Hello {{you}}</h1>
  </body>
</html>

content.json:

{ 
  "you": "world"
}

Thanks to Julien Tanguy 🙏

Add an option to support transparency

I also added an option transparent to enable support of transparency in the CLI too:

npx node-html-to-image-cli --type png --transparent ./index.html ./image.png
