BuzzCrack

My tool for looking up multiple courses at a time and registering for specific CRNs without touching BuzzPort.

Setting up project

BuzzCrack works on Node.js; download it and run the following in the BuzzCrack directory after cloning.

npm install

BuzzCrack needs a cookie to "impersonate" you in order to register/look up classes.

Steps to get/refresh token:

1. Log in to Buzzport
2. Open Registration
3. Open browser web inspector
4. Copy SESSID cookie

• Safari: Dev Tools > Storage > Cookies
• Chrome: Dev Tools > Application > Cookies

5. Create and paste into .env file like "SESSION_TOKEN=..."

Section Look-Up

Looking up open sections is done by providing a list of course names. Locate and replace the classes array in course.js file. Change the values there with your own course names (e.g. CS 5901).

Run the look-up with node course.js

Something similar to the following will be printed:

CS 5901
status  crn     section mode days time               rem   wl_cap wl_act  wl_rem  instr
SR      42400   JDA     L    M    09:30 am-10:20 am  14    10     0       10      Anders, L.
SR      19023   SLS     L    M    12:30 pm-01:20 pm  27    10     0       10      Burdell, G. P.
...

This will give you information about all open sections of the course desired. Notably, the remaining open spots (rem), waitlist capacity (wl_cap), and waitlist remaining spots (wl_rem)

Registration

Registration is done by providing a list of CRNs to register for. Locate and replace the CRNs array in register.js file. Change the values there with your own CRNs, found by looking up with the course.js section.

Finally, run node register.js
