How to use Puppeteer in a NodeJS Docker Project? -Browser Not Found

[miu]

Hi everyone,

I'm trying to build a custom module for my NodeJS project that uses Puppeteer to take screenshots of websites. I'm using Docker for my development environment, as recommended in the Wappler docs.

My problem is that when I run my Server Action, I get an error that the browser cannot be found. I've tried a few things I found online, like creating a custom Dockerfile to install google-chrome-stable or chromium-browser, but the installation seems to fail inside the container (I used docker exec to check, and the browser isn't there).

Has anyone successfully used Puppeteer in a Wappler Docker project?

What is the recommended "Wappler way" to install Chrome/Chromium and its dependencies so that Puppeteer can find it?

Any advice or pointers would be a huge help! Thanks so much.

MODULE: Generate PDF from EJS Template with Puppeteer

First and foremost, a lot of credit has to go to @sid. Their module for HTML to PDF was the basis of this one. SO WHY CREATE ANOTHER PDF MODULE? The reasoning here was to make it easier to generate a bank of EJS templates that you could visually build, add JSON data to, and dynamically generate the resulting HTML. My first thought, when using @sid's module was to plug my routes into Puppeteer, however, along with this came the problems of security enforcers forcing Puppeteer to login in (which…

Just a quick tip. Puppeteer acts as the browser so you don't need to install Chrome and Puppeteer as Puppeteer will launch its own bundled version of Chrome.
