Puppeteer-batch-screenshots

Make screenshots of your websites in batch.

Let's say you have to make 100 web page screenshots in a row daily. The most of CLI-enabled screenshot tools allow you to make one single screenshot at a time, which means every time the new Node + Chrome instance gets initialised. This tool saves a good amount of time by batching these tasks.

---

Tool based on puppeteer.

Installation and Usage:

npm i -g puppeteer-batch-screenshots
puppeteer-batch-screenshots config.json

alternatively you can install it as a local dependency

mkdir my-perfect-screenshoot-tool && cd my-perfect-screenshoot-tool
npm init -y
npm i puppeteer-batch-screenshots
node /node_modules/puppeteer-batch-screenshots/index.js config.json

    // Viewport width, defaults to 1280
    "width": 1440,
