To make a random transaction for every user in the DB:
- Go to your project's folder
- run:
$ npm run make_a_transaction - control + c to exit the script
-
-
-
Every route start with baseURL/user/ will check the token sent by a client, and the server will recognize the token and know which user you are. If you update your email, username or password, the token will expire. Also, the token will expire after it was generated 24h.
-
Our backend will send a confirmation link when user registers his/her account. The link contains an encrypted parameter which includes user registration information. When the user clicks the link backend verify and decode the parameter using a private key to acquire the user's registration information then create an account accordingly.
-
-
- Administrators can manually send notifications to every user's email. Whereas at every day 8 am users will receive an email containing the latest news about the coin they hold the most.
-
-
We are currently using Gmail for sending email, which could cause problems when it comes to sending bulk emails.
-
When sending notifications, server traverses the every user. And traverse every coin the user has. The time complexity will be O(n * m), which should be improved.
-
All the array parameters are not available, you can only pass one single parameter instead!
-
Update setting can set username and email but does not check if they are duplicated.
-
For recommendation, we use user-based recommendation. The problems with this method are that in the early stage of the product, there is no sufficient user's behaviors data. Second, how to store the users' similarity to the relational database is a question. The space complexity of the data will be O(n^2).
