How do I Throttle BrowserSync's speed?

How can I configure BrowserSync (from its API) to serve up content at a slower rate?

Ideally I'd like to be able to serve only certain files at the throttled rate, so when developing,

loads fast and
loads slowly, so I can effectively demo loading states while developing web apps that decouple data and presentation.

  1. start browser-sync: browser-sync start --server --files "src/*.*"
  2. open the browser-sync UI (e.g. http://localhost:3001/) and go to "Network Throttle" enter image description here
  3. select "Speed", then "Create Server"
  4. Use the new server instance which is now running at the defined speed


You can run multiple throttled server instances an the same time - eg. to simulate CDN behavior (where the fastest wins)

You can also simulate latency! Have a look at the bs-latency Plugin ...
