Size of local chromium

[prakashpsde]

npm i puppeteer

Installing puppeteer installs a local-chromium which is of size 292MB.
Generating PDF with HTML is the only feature that I'm using with puppeteer for now.
Is there a way to lower the size of npm?

• Puppeteer version: 1.6.2
• Platform / OS version: Windows 8.1 - 62-bit
• URLs (if applicable):
• Node.js version: 9.5.0

It looks like puppeteer downloads snapshots from https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html

Looking at revision 579032, some download sizes are:

• Mac / chrome-mac.zip: 84.74 MB
• Linux_x64 / chrome-linux.zip: 107.28 MB
• Win_x64 chrome-win32.zip / : 133.89 MB

Maybe 292MB is the unzipped size?

I agree these are very large downloads. Are these builds really optimized for their purpose, or are they statically linked with dependencies unrelated to headless functionality?

Is there a guide to making our own builds of chromium headless for all platforms?

@prakashpsde you can use PUPPETEER_SKIP_CHROMIUM_DOWNLOAD env variable to skip download and then use your own build. Since you only need PDF generation, you can build headless_shell - it should be way slimmer. You can read about building various chromium targets on
chromium.org.

@tsullivan These are builds that we get from Chromium's CI - they are general-purpose chromium builds.

@aslushnikov Do you know where I could find the source for the chromium_revision specified in package.json? I couldn't find any related git commits, only some references in comments such as this one: chromium/chromium@dcf17fe

Searching the comments doesn't seem like a very practical way for me to find this, though.

Just following up. You find it here:

Does puppeteer-core fix all the problems mentioned above, FYI I'm ok with headless for my utility. So, Should I prefer puppeteer-core over puppeteer?
