Handling Signin and Signout
To signin your users, make sure you have at least one authentication method setup. You then need to build a button which will call the sign in function from your Auth.js framework package.
import { signIn } from "@/auth.ts"
export function SignIn() {
return (
<form
action={async () => {
"use server"
await signIn()
}}
>
<button type="submit">Sign in</button>
</form>
)
}In a client component, you can still use the imports from next-auth/react as they are marked with the "use client;" directive.
import { signIn } from "next-auth/react"
export function SignIn() {
return <Button onClick={() => signIn()}>Sign In</Button>
}You can also pass a provider to the signIn function which will attempt to login directly with that provider. Otherwise, when clicking this button in your application, the user will be redirected to the configured sign in page. If you did not setup a custom sign in page, the user will be redirected to the default signin page at /[basePath]/signin.
Once authenticated, the user will be redirected back to the page they started the signin from. If
you want the user to be redirected somewhere else after sign in (.i.e /dashboard), you can do so
by passing the target URL as redirectTo in the sign-in options.
import { signIn } from "../../auth.ts"
export function SignIn() {
return (
<form
action={async () => {
"use server"
await signIn("github", { redirectTo: "/dashboard" })
}}
>
<button type="submit">Sign in</button>
</form>
)
}Signout
Signing out can be done similarly to signing in. Most frameworks offer both a client-side and server-side method for signing out as well.
To sign out users with a form action, you can build a button that calls the exported signout function from your Auth.js config.
import { signOut } from "../../auth.ts"
export function SignOut() {
return (
<form
action={async () => {
"use server"
await signOut()
}}
>
<button type="submit">Sign Out</button>
</form>
)
}Again, in a client component, you can use the next-auth/react imports as they are marked with the "use client;" directive.
import { signOut } from "next-auth/react"
export function SignOut() {
return <Button onClick={() => signOut()}>Signout</Button>
}Note that when signing out of an OAuth provider like GitHub in an Auth.js application, the user will not be signed out of GitHub elsewhere.
