ETOOBUSY 🚀 minimal blogging for the impatient
An alternative example for the EventSource web service.
In previous post Fixing an example in Mojolicious I bragged about how fixing a small issue in an example makes me feel part of the community. By the way, I think you should participate in the community and brag about it too!
I was looking at that example because I was interested into the EventSource API for a small project involving a game, rolling some dice on the web and being able to play at a distance with physical stuff (apart from the dice, of course). Hopefully more on this in the future.
I modified the example in the Mojolicious Cookbook guide to fit my example, here’s the code:
I guess you know how to start it, so I won’t bother you here.
After the program is started, you can try it on the local host like this:
- decide a name for your box, for example
- point a couple of browser windows to http://127.0.0.1:3000/box/foo - you should see that a number between 0 and 99 (included) is shown in both (the same number);
- use another browser window, or a command line
curlcommand, to trigger the generation of a new value using url http://127.0.0.1/tickle/foo - you should see it appear in both windows
- open another browser window to http://127.0.0.1:3000/box/foo - you should just see the last number that was generated in it
If you use
bar instead of
foo you will look into a different
box… with a different sequence of numbers.
I know, I know… I should have used a POST and not a GET… but it’s a proof of concept!
