Create sign up page

We can now implement our sign up page. Create a page.jsx file in the src/app/signup directory:

React
// src/app/signup/page.jsx

import {
  getLoggedInUser
} from "@/lib/server/appwrite";

export default async function SignUpPage() {
  const user = await getLoggedInUser();
  if (user) redirect("/account");

  return (
    <>
      <form action={signUpWithEmail}>
        <input
          id="email"
          name="email"
          placeholder="Email"
          type="email"
        />
        <input
          id="password"
          name="password"
          placeholder="Password"
          minLength={8}
          type="password"
        />
        <input
          id="name"
          name="name"
          placeholder="Name"
          type="text"
        />
        <button type="submit">Sign up</button>
      </form>
    </>
  );
}

This is an HTML form with an email and password input. When the form is submitted, we want to send the email and password to Appwrite to authenticate the user. To use Next.js form actions we create the signUpWithEmail function in the same file:

React
// src/app/signup/page.jsx

// previous imports ...

import { ID } from "node-appwrite";
import { createAdminClient } from "@/lib/server/appwrite";
import { cookies } from "next/headers";
import { redirect } from "next/navigation";

async function signUpWithEmail(formData) {
  "use server";

  const email = formData.get("email");
  const password = formData.get("password");
  const name = formData.get("name");

  const { account } = await createAdminClient();

  await account.create(ID.unique(), email, password, name);
  const session = await account.createEmailPasswordSession(email, password);

  cookies().set("my-custom-session", session.secret, {
    path: "/",
    httpOnly: true,
    sameSite: "strict",
    secure: true,
  });

  redirect("/account");
}

// the SignUpPage component ...

The signUpWithEmail function is an async function that takes the form data as an argument. It uses the createAdminClient function to create an admin Appwrite client and then calls the createEmailPasswordSession method on the account object. This method takes the email and password as arguments and returns a session object. We then set the session secret in a cookie and redirect the user to the account page.
