Hi there - is there a way to automatically log a user in upon sign up?

Hi @NemusAI. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Yes, there is a way to automatically log a user in upon sign up in Wasp. However, it's important to note that the signup() action in Wasp does not automatically log in the user. You will need to call the login() action after signup() to log the user in. Here is an example of how you can do this:

import { signup, login } from 'wasp/client/auth'  
  
import { useState } from 'react'  
import { useHistory } from 'react-router-dom'  
  
export function Signup() {  
 const [username, setUsername] = useState('')  
 const [password, setPassword] = useState('')  
 const [error, setError] = useState(null)  
 const history = useHistory()  
  
 async function handleSubmit(event) {  
 event.preventDefault()  
 try {  
 await signup({  
 username,  
 password,  
 })  
 await login(username, password)  
 history.push("/")  
 } catch (error) {  
 setError(error)  
 }  
 }  
  
 return (  
 <form onSubmit={handleSubmit}>  
 {/* ... */}  
 </form>  
 );  
}

import { signup, login } from 'wasp/client/auth'  
  
import { useState } from 'react'  
import { useHistory } from 'react-router-dom'  
  
export function Signup() {  
 const [username, setUsername] = useState('')  
 const [password, setPassword] = useState('')  
 const [error, setError] = useState(null)  
 const history = useHistory()  
  
 async function handleSubmit(event) {  
 event.preventDefault()  
 try {  
 await signup({  
 username,  
 password,  
 })  
 await login(username, password)  
 history.push("/")  
 } catch (error) {  
 setError(error)  
 }  
 }  
  
 return (  
 <form onSubmit={handleSubmit}>  
 {/* ... */}  
 </form>  
 );  
}

In this example, after the signup() action is called with the user's username and password, the login() action is called with the same username and password. If both actions are successful, the user is redirected to the home page. You can find more information about the signup() and login() actions in the Wasp documentation (https://wasp-lang.dev/docs/auth/username-and-pass#signup). Please note that this approach logs the user in on the client side. If you want to execute custom server actions after a successful signup or login, you might need to create a custom sign-up action. You can find more information about this in the Wasp documentation (https://wasp-lang.dev/docs/auth/email#creating-a-custom-sign-up-action). Sources: - Wasp Documentation - signup() (https://wasp-lang.dev/docs/auth/username-and-pass#signup) - Wasp Documentation - login() (https://wasp-lang.dev/docs/auth/username-and-pass#login) - Github Issue - On signup(), make it clear you are not logged in (https://github.com/wasp-lang/wasp/issues/151) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @NemusAI, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Yeah what Kapa the bot said here is not really the best. This is an interesting question, I think we don't have a way to do that directly at the moment. @miho will konw this better actually, let's see what he says!

If you used username & password auth method -> it will log the user automatically. For email method -> this is not possible since we require that the email address is first confirmed before allowing log in.
