Next.js Email Client
This is a simple email client built with Next.js and Postgres. It's built to show off some of the features of the App Router, which enable you to build products that:
- Navigate between routes in a column layout while maintaining scroll position (layouts support)
- Submit forms without JavaScript enabled (progressive enhancement)
- Navigate between routes extremely fast (prefetching and caching)
- Retain your UI position on reload (URL state)
The first version of the UI was built with v0.

Setup
In order to run this project locally, you'll need to create a Postgres database and add the connection string to your .env.local file.
Further, you'll need to create the tables and insert some sample data.
Follow these steps to get started:
- Create a Postgres database
- Navigate to the
.env.localtab in the quickstart section Postgres dashboard - Copy the snippet and paste it into your
.env.localfile - Run
pnpm run setupto create the tables and insert sample data
This example uses postgres, which makes it compatible with any Postgres database. You can use DATABASE_URL or POSTGRES_URL to connect to your database.
POSTGRES_URL="postgres://user:password@host:port/database"

Database Relationships
- Users can send and receive emails (users.id -> emails.sender_id and emails.recipient_id)
- Users can have multiple folders (users.id -> user_folders.user_id)
- Folders can contain multiple emails (folders.id -> email_folders.folder_id)
- An email can be in multiple folders (emails.id -> email_folders.email_id)
