 1 | # Leetcode Session Creator
 2 | 
 3 | **[DEPRECATED]** Leetcode has already moved on to their new lists feature. This repository will no longer be of use.
 4 | 
 5 | ----------------------------------------------
 6 | 
 7 | Recently Leetcode started to deprecate the old session system,
 8 | and the button to create a new session is not clickable,
 9 | sooo we cannot create new sessions anymore.
10 | This is a simple script that creates a new session for you.
11 | 
12 | ![image](https://github.com/user-attachments/assets/95a6c543-90d8-483c-ae67-63e1dc5e543a)
13 | 
14 | ## How to use
15 | 
16 | 1. Clone the repository, make sure you have Node.js version 18+ installed
17 | 2. Open index.js
18 | 3. Enter your Leetcode session under LEETCODE_SESSION
19 | 4. Enter your Leetcode csrf token under CSRF_TOKEN
20 | 5. Change NEW_SESSION_NAME to the name of the new session you want to create
21 | 6. Fire up your terminal and run `node index.js`
22 | 7. Enjoy
23 | 
24 | WARNING: Sometimes Leetcode servers reject requests with 403 (maybe it hits new (post deprecation) server nodes with their Load Balancer
25 | (just a guess).
26 | 
27 | I have added retries count to make requests run until it passes with 200. If it stops working completely (and I'm sure it will after some time)
28 | it's nothing we can do.
29 | 
30 | ## How to get Leetcode session and csrf token
31 | 
32 | 1. Open Leetcode in your browser
33 | 2. Open browser's developer tools
34 | 3. Go to Application tab
35 | 4. Find the cookies section
36 | 5. Copy the value of `LEETCODE_SESSION` and `csrftoken`
37 | 
38 | ## Disclaimer
39 | 
40 | Use at your own risk. Since this is not an official API. Leetcode may change the way they handle sessions at any time,
41 | remove this endpoint, rate limit it, or do anything else. Since this script is using deprecated way
42 | of creating sessions, it's just a matter of time when they will remove it and this script will stop working.
