Docker/dblworks/pdf-renderer

It's an HTTP service that will convert a HTML string to PDF. It uses Puppeteer under the hood, which means rendering is performed by Chromium's render engine; thus the HTML sent to this service should be developed and tested using Chrome/Chromium.

Read more about technical details of Puppeteer on their Github repo.

Because it's a docker image, it can be installed anywhere

To try out locally:

docker build -t pdf-renderer .
docker run --name pdf-renderer -d -p 5017:5017 pdf-renderer

If you prefer running the code in your system

⚠️ macOS Monterey runs the ControlCenter on port 5000.

Prepend e.g. PORT=5017 to the command

yarn run dev

or

yarn run local

which runs NODE_ENV=development yarn run dev.

Passing NODE_ENV=development will let puppeteer auto-detect the executable path, which is different from the hardcoded path, that is specifc for a Linux deploy.

      browser = await puppeteer.launch({
        headless: 'new',
        args: [
          '--no-sandbox',
          '--disable-setuid-sandbox',
        ],
        // executablePath: 'google-chrome-stable',
      })

AWS_BUCKET_NAME

To store the files to AWS we need to config the system to use aws-sdk

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY

(this will need to be provided to you)

filename(optional) - String, current timestamp by default - The filename that the PDF file will be created.

format(optional) - Object, {} by default.

{
  "landscape": false, // - Boolean, `false` by default - Whether the PDF should be in landscape mode
}
