how can we use appwrite auth for the backend?

Hello

I have a MERN application.
Currently using auth in the backend sending jwt to React frontend.

Each api call in express server validates the jwt before sending response.

Can i replace entire auth with appwrite?

/register and /login should be replaced by appwrite.
Means when /register calls from frontend backend should use appwrite.
When /login calls by react app backend express should check user in appwrite and create the jwt and should send to frontend.

Is this possible?

It wont depend on the route, After you hit the route, Write a controller which calls the server SDK of appwrite.

https://appwrite.io/docs/getting-started-for-server

this is the intro for server sdk

https://appwrite.io/docs/server/users This is the section you need to study to implement authentication.

Accounts: https://appwrite.io/docs/server/account

Teams: https://appwrite.io/docs/server/teams

You just need to create a controller for register and login route and write the appwrite logic to perform CRUD operations on USER, there are may features such as Verifying the emmail, Password Recovery in Account module of Appwrite.

Yes
I'll go through this

Previously i got for Registration logic

Login method was not found in Server sdk
That was in client sdk

For create user we send email and password

Similar method is not there to login i guess

Yes bht createSession method is in another sdk right?

https://appwrite.io/docs/server/account?sdk=nodejs-default#accountGetSession

Aren't you using Account ?

Are you using Users?

Create an account using Users and login the user using Account. It will be fine

User server sdk in account also.
