getScreenMedia

What is this?

A tiny browser module that gives us a simple API for getting access to a user's screen.

It gives us a cleaner node.js-style, error-first API and cross-browser handling. No browser support checking necessary; lack of support is treated in the same way as when the user rejects the request: the callback gets passed an error as the first argument.

Suitable for use with browserify/CommonJS on the client.

Installing

npm install getscreenmedia

How to use it

First build and install a domain-specific extension for Chrome. Firefox and Microsoft Edge will work out of the box.

Use the snippet below to get a screen stream, similar to getUserMedia.

var getScreenMedia = require('getscreenmedia');

getScreenMedia(function (err, stream) {
    // if the browser doesn't support user media
    // or the user says "no" the error gets passed
    // as the first argument.
    if (err) {
       console.log('failed');
    } else {
       console.log('got a stream', stream);  
    }
});

Why?

All supported browsers require the use of an extension and don't offer an cross-browser API which is annoying and error-prone. Node-style (error-first) APIs that are cross-browser, installable with npm and runnable on the client === win!

Error handling

Error handling (denied requests, etc) are handled mostly by the underlying getUserMedia lib. However this adds one more error type:

  • "HTTPS_REQUIRED"

Because that's a current requirement of Chrome.

See the handling errors section of the getUserMedia lib for details about how errors are handled.
