Below is a review of the most common PHP PDF generators, both commercial and open-source libraries. To opt in to the new Headless mode in Puppeteer: import puppeteer from 'puppeteer' Ĭonst browser = await puppeteer.

As part of this removal, we’ll make the old Headless available as a separate standalone binary for those users who can’t upgrade yet. We plan to completely remove the old Headless from the Chrome binary and stop supporting this mode in Puppeteer later this year.

To try the new Headless mode, pass the -headless=new command-line flag: chrome -headless =newįor now, the old Headless mode is still available via: chrome -headless =oldĬurrently, passing the -headless command-line flag without an explicit value still activates the old Headless mode - but we plan to change this default to new Headless over time. All other functionality, existing and future, is available with no limitations. We’re excited to announce that the new Headless mode is now available in Chrome 112! In this mode, Chrome creates but doesn’t display any platform windows.

In 2021, the Chrome team set out to solve this problem, and unify Headless and headful modes once and for all. The same goes for any other browser-level functionality: unless Headless had its own, separate implementation of it, it wasn’t supported. It also excluded any automated testing that relied on having a browser extension installed, for example. This created a confusing situation where any automated browser test might pass in headful mode but fail in Headless mode, or vice versa - a major pain point for automation engineers.

Because Headless was a separate implementation, it had its own bugs and features that weren’t present in headful Chrome.

It doesn’t share any of the Chrome browser code in //chrome.Īs you might imagine, implementing and maintaining this separate Headless browser came with a lot of engineering overhead - but that wasn’t the only problem. Technically, the old Headless was a separate, alternate browser implementation that happened to be shipped as part of the same Chrome binary. Perhaps surprisingly, this wasn’t actually true. The command-line snippet we showed earlier uses the -headless command-line flag, suggesting that Headless is just a mode of operation of the regular Chrome browser. Here’s a minimal command-line example of using Headless mode to create a PDF file of a given URL: chrome -headless -print-to-pdf # What’s new in Headless?īefore we dive into the recent Headless improvements, it’s important to understand how the “old” Headless worked. Headless mode is a popular choice for browser automation through projects like Puppeteer or ChromeDriver. Essentially, running Chrome without chrome! # Backgroundīack in 2017, Chrome 59 introduced the so-called Headless mode, which lets you run the browser in an unattended environment without any visible UI. Chrome’s Headless mode just got a whole lot better! This article presents an overview of recent engineering efforts to make Headless more useful for developers by bringing Headless closer to Chrome’s regular “headful” mode.
