CLI that makes use of the Chrome Dev Tools Protocol to export a HTML file as an image or as PDF document.
This tool should work with any version of Chromium above 70, here you can find a special (--headless only) build of Chromium 74 with a drastically decrease in bundle size (linux based systems only).
Makes use of the NodeJS implementation of the protocol, Puppeteer, to create a CLI that export a HTML file as an image or as PDF document.
node puppeteer-export.js --type=PORTABLE_DOCUMENT_FORMAT --source=/path/to/source.html --dest=/path/to/dest.pdf --format=A4 --width=400 --height=200 --executablePath=/opt/google/chrome/chrome
--type=PORTABLE_DOCUMENT_FORMAT: {String} media type can be IMAGE or PORTABLE_DOCUMENT_FORMAT
--source=/path/to/source.html: {Path} path of HTML input file
--dest=/path/to/dest.pdf: {Path} destination file
--format=A4: {String} paper size format, PORTABLE_DOCUMENT_FORMAT only, priority over --width and --height
--width=400: {String} width of the new file, can be in: px, cm or in
--height=200: {String} height of the new file, can be in: px, cm or in
--executablePath: {Path} path pointing to a Chromium executable.
One of the limitations with this client is that it requires NodeJS intalled in the machine. You can use pkg to port a NodeJS app to MACOS, Linux or Windows. One of the drawbacks of this approach is the bundle size (~46MB + app size itself).
Usage:
Open the terminal and type:
pkg wrapper.js --output=puppeteer --target=node10
Now you have a executable called puppeteer that dont requires NodeJS to work.
The new usage is:
./puppeteer ./puppeteer-export.js --type=IMAGE --source=/path/to/source.html --dest=/path/to/dest.png --width=300px --height=200px --executablePath=/path/to/chromium
Same as before just replace node puppeteer-export.js for ./puppeteer.
Open the terminal and type:
./pack.sh 1.0
It will generate a dist folder with a zip file containing all resources.
You can use https://github.com/raff/godet or https://github.com/mafredri/cdp implementations of the protocol to get rid of Puppeteer and build the same CLI in Golang thus reducing the bundle size.
