If you like to use any other database, the provided functionality of the database may differ, but the actual hashing should work similar. So to create such a pre-save hook I now head into Server, Models, and then into User Model. The first thing I have to do is I have to install bcrypt. So I'm stopping the Node.js process now with Ctrl C, and then I'll run npm install-S bcrypt. Next we of course have to require bcrypt in our model file. So add const bcrypt = require bcrypt and now we are ready to implement this pre-save hook for that scroll down somewhere of the line 44. First I will create a helper that will do the actual password hashing. Bcrypt today offers a promise based interface, a callback based interface, and also a synchronous one.
