Screenshotter

A Node server that takes screenshots of websites with node-webshot.

Install

npm install

Running

npm start # listens on 8080 by default

Usage

You can either get the image via an HTTP response, or instruct screenshotter to save the screenshot in a path within its local filesystem.

Get the screenshot in the HTTP response

The following shell script uses curl to request a screenshot for lucify.com, receives it in the body of a HTTP response, and pipes the result into img.jpg.

read -r -d '' BODY <<EOF
{
  "url": "lucify.com",
  "options": {
    "streamType": "jpg",
    "quality": 90,
    "windowSize": {
      "width": 2000,
      "height": 1500
    }
  }
}
EOF
echo $BODY | curl -v -X POST -H "Content-Type: application/json" -d '@-' localhost:8080/ > img.jpg

Save the screenshot in a file

The following shell script uses curl to request the screenshotter running at localhost:8080 to take a screenshot of lucify.com and store it in its local filesystem in /tmp/screenshot.jpg. On success, the screenshotter responds with status code 200.

read -r -d '' BODY <<EOF
{
  "url": "lucify.com",
  "fileName": "/tmp/screenshot.jpg",
  "options": {
    "streamType": "jpg",
    "quality": 90,
    "windowSize": {
      "width": 2000,
      "height": 1500
    }
  }
}
EOF
echo $BODY | curl -v -X POST -H "Content-Type: application/json" -d '@-' localhost:8080/

Docker

Screenshotter can be run in Docker. Docker needs to be installed in order to run these commands.

Build Docker image with

docker build -t screenshotter .

You can then run it with

docker run --rm -ti -e 'DEBUG=1' -p 8080:8080 screenshotter

Remarks

There's an issue with webshot on newer node versions, so we install it straight from a Pull Request.
