Tech Stack
The tech stack I used to build the url shortener is as follows:
- Next JS 16.1.1
- Prisma (ORM database)
- Neon Database Postgresql (optional)
- Auth JS as authentication
- Login with Google as authentication
Prisma Schema
The following is the prism schema that I made :
generator client {
provider = "prisma-client-js"
}
datasource db {
provider = "postgresql"
url = env("DATABASE_URL")
}
model User {
id String @id @default(cuid())
name String?
email String? @unique
emailVerified DateTime?
image String?
password String?
accounts Account[]
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
links Link[]
}
model Account {
userId String
type String
provider String
providerAccountId String
refresh_token String?
access_token String?
expires_at Int?
token_type String?
scope String?
id_token String?
session_state String?
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
user User @relation(fields: [userId], references: [id], onDelete: Cascade)
@@id([provider, providerAccountId])
}
model Link {
id String @id @default(cuid())
key String @unique // short code (abc123)
url String // destination URL
title String?
description String?
password String?
expiresAt DateTime?
workspaceId String
domainId String?
userId String
user User @relation(fields: [userId], references: [id])
clicks ClickEvent[]
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
}
model ClickEvent {
id String @id @default(cuid())
linkId String
link Link @relation(fields: [linkId], references: [id])
ip String?
country String?
city String?
device String?
browser String?
os String?
referer String?
createdAt DateTime @default(now())
}ENV File
Here is the env file that I use:
DATABASE_URL=
AUTH_SECRET= # Added by `npx auth`. Read more: https://cli.authjs.dev
AUTH_GOOGLE_ID=
AUTH_GOOGLE_MAIL=
NEXT_PUBLIC_BASE_URL=Specify a specific email address to use for authentication. This prevents you from logging in to Google with just any account. For more details, see the section on creating authentication.

As I mentioned in my tech stack, I use auth.js as my primary authentication for security. Here's my auth.js setup:
import Google from "next-auth/providers/google";
export default {
providers: [
Google
],
} satisfies NextAuthConfig;import NextAuth, { DefaultSession } from "next-auth";
import authConfig from "./auth.config";
import { PrismaAdapter } from "@auth/prisma-adapter";
import { db } from "./lib/db";
export const { handlers, signIn, signOut, auth } = NextAuth({
adapter: PrismaAdapter(db),
callbacks: {
async signIn({ user }) {
const allowedEmail = process.env.AUTH_GOOGLE_MAIL;
if (!allowedEmail) return false;
// hanya email yang diizinkan
if (user.email !== allowedEmail) {
return false;
}
return true;
},
async session({ session, token }) {
if (session.user) {
session.user.id = token.sub as string;
session.user.email = token.email as string;
session.user.name = token.name as string;
session.user.image = token.picture as string;
}
return session;
},
async jwt({ token }) {
return token;
},
},
session: {
strategy: "jwt",
},
pages: {
signIn: "/auth/login",
error: "/auth/login",
},
...authConfig,
});In the sign in section, users can only log in by using a specific email that has been set in their .env.
Creating a Unique Code
Here I use nanoid to generate it
<FormField
control={form.control}
name="key"
render={({ field }) => (
<FormItem>
<FormLabel>Custom Key (Optional)</FormLabel>
<FormControl>
<div className="flex items-center space-x-2">
<Input
placeholder="my-custom-link"
{...field}
disabled={isPending}
/>
{/* Generate Kode Unik nya */}
<Button
type="button"
variant="outline"
onClick={() => form.setValue("key", nanoid(7))}
disabled={isPending}
>
Generate
</Button>
</div>
</FormControl>
<FormMessage />
</FormItem>
)}Preview Table
Create Link Form
Here is the form to create a link on this project in the route/dashboard
Redirect Original Page URL
The project can be accessed at the link below.
