node-html-2-image v1.0.3
Description
A node.js command line utility that generates an image (png, jpeg or webp) from html file or URL with the help of puppeteer.
Install
npm install -g node-html-2-imageUsage
Generate an image from URL:
html2image --url=https://www.google.com --dest=google.png --type=pngGenerate an image from local file:
html2image --src=my-site.html --dest=my-site.jpg --type=jpegGenerate an image from local file but run it in a local server (many times local html files will not load Javascript so they need to be run from a local server):
html2image --src=my-site.html --local-server --dest=my-site.jpg --type=jpegNOTE: The shell commands must not be run under root. Chromium doesn't allow it.
