Is there a way to limit speed and response time in Node (Express)?

Question

I would like to see how my website reacts to a slow connection.

Is there a way I can limit express to responding with slow speeds or delays? I know I can implement setTimeout calls on paths, but what about static assets?

Answer 1

As I've mentioned in the comments, modern browsers support network speed simulation (and much more). Doing any programatic latency faking within your app is not a good approach because network simulation is difficult, it's hard to do it reliably and you could end up polluting your code a lot.

You should use a browser to do this:

• Chrome (best support)
• Firefox
• Edge (not yet supported but it has been suggested)

There are also many other tools and resources you can use:

• crapify (NodeJS)
• How to simulate slow connection on a Mac
• Fiddler
• and many more...
