#node-imagecapture-server Fire up a server that will take a screenshot of your website. Uses Chrome headless, via puppeteer.
$ npm install
$ node server.js
| Parameter | Description |
|---|---|
| url | The target URL for the screenshot |
| ww | (optional) The width of the window. (default: 1024) |
| wh | (optional) The height of the window. (defaults to height of content) |
| wait | (optional - true,false) Wait for the target webpage to trigger window.triggerScreenshot(); |
| timeout | (optional - integer) Timeout in ms (defaults to 30000) |
Some older sites use the PhantomJs branch rather than the main Puppeteer branch. Note that these branches are slightly incompatible. Switching a site using one branch to the other requires slightly different JavaScript when using the wait param to have the site trigger taking a screenshot. Switching without making the required code changes will result in timeout errors.
The PhantomJs branch can be set up as a Windows service (using NSSM to run node.exe server.js for example), or as an IIS site. To set it up as an IIS site, create a new site in IIS as normal, go to Default Document, and add server.js.
You can test that the site is set up correctly by browsing to <yourPhantomJsIisSite>?url=<someTestSiteLikeGoogle>. If you receive an error about spawning phantomJs, make sure that the phantomPath configured in server.js is the correct location for phantomJs.exe. You can also run "phantomjs testing.js" to check for console errors.
