are we adding two tutorials? @anurag-arasan I see emitters and sockets in navigation |
I had restructured the work I did on emitters (from the initial PR) to be an "emitters" tutorial and created a new sockets tutorial which focuses on the actual use of Socket.IO in Covey.Town. If the emitters tutorial isn't required, we can remove it, but the content serves as a decent introduction to socket architecture in my opinion. |
|
Then perhaps, we should add a note at the start of this tutorial to look at the other tutorial first. |
I believe I did that already, from socket.md: *Note: this tutorial assumes you have an understanding of the emitter pattern. If you need a review, please see the Emitters Tutorial on the course site. |

In 'tutorials', both 'sockets' and 'emitters' point to the sockets tutorial, so I can't tell what's going on. The tutorial that I can see is full of details of how sockets are implemented(?)/used(?) in covey.town. That doesn't comport with my conception, at least. A tutorial should cover the basics with the least possible amount of incidental complexity. What there is essential and what is just c.t noise? For the emitters tutorial, I'd suggest that you look at my slides on emitters and edit them to include JB's notes about how to structure the system:
As it turns out, the c.t protocol doesn't have unique IDs :) As mentioned above, I can't see what you wrote for the 'emitters' part of the tutorial, so I don't know whether you've already done something like that. For the 'sockets' part of the tutorial, you need to emphasize JB's remark about using typed emitters (via socket-io) as an abstraction of websockets . |
|
Both "emitters" and "sockets" still point to https://deploy-preview-28--magical-haupia-72594e.netlify.app/tutorials/emitters, which is the sockets tutorial. Please move it to ..../sockets . Is there a separate tutorial on emitters? If not, please remove any references to it. Otherwise, it is good enough for now. |
Apologies for the delayed response, I have updated the files to point to the correct urls for emitters and sockets respectively. Will update tutorials according to feedback by EOD. To clarify, the "Emitters" tutorial covers the general emitter pattern and glosses over the use of the typed emitter, while the socket tutorial discusses socket implementation, using Covey.Town as a concrete example. |

The emitter tutorial is pretty good, but it doesn't show how to knit the clients and the server together. See attached file. (suffix changed from .ts to .txt to satisfy github rules for attached files. |
|
I'd also change "Implementing Emitters" to "Using Emitters" :) |
|
As for the socket tutorial, you need to change "Implementing Sockets" to "Using Sockets". None of this code implements sockets-- that's all in socket.io and socket.io-client . These packages are the ones that actually implement the asynchronous socket behavior. In the Contents, the first two links (Understanding Sockets and Implementing Sockets) work properly, but none of the rest seem to. In the long run, I think it would be better to replace the huge covey.town examples with an example that extends the example in the emitter tutorial with one where the server and client are in separate processes, connected by http. But that's probably too much to expect for this point in the course and this point in the semester. Let's revisit this next semester, ok? |
