/puppeteer-example

Primary LanguageJavaScript

This example is to be used with the Browserless template

Create a reference variable on your Railway service that you deploy your app to

BROWSER_WS_ENDPOINT=${{Browserless.BROWSER_WS_ENDPOINT}}

Then use process.env.BROWSER_WS_ENDPOINT in code

Before

const browser = await puppeteer.launch();

After

const browser = await puppeteer.connect({ browserWSEndpoint: process.env.BROWSER_WS_ENDPOINT });

The rest of your JS/TS code remains the same with no other changes required.

How to avoid installing Chrome / Chromium (and accompanying dependencies) into your container

  • Switch the puppeteer dependency out for puppeteer-core

    • npm uninstall puppeteer -> npm install puppeteer-core

    • puppeteer-core will not auto install Chrome or Chromium

  • Use this repositories nixpacks.toml file in your project

    • The empty aptPkgs array will prevent Railway from installing the now unwanted Chrome dependencies
