This is a trimmed down version of an app I built about helping people declutter.
I am learning Next.js 15 and I wanted to build a simple demo to get familiar with the new features, such as useOptimistic, useActionState, server actions and explore new ways to manage state.
This demo combines Context API and the useOptimistic hook to make updating items feel more responsive. It also leverages Next.js's revalidatePath to keep the UI in sync with the server state in a more seamless way.
To run it locally:
git clone https://github.com/hcsum/interactive-nextjs-list-demo.git
cd interactive-nextjs-list-demo
npm install
Create a .env file and add the following:
If use sqlite:
DATABASE_URL="file:./dev.db"
If use postgres:
DATABASE_URL=<your-postgres-connection-string>
Modify prisma/schema.prisma to use the database you want to use.
Run db migrations:
npx prisma migrate dev
Start the server:
npm run dev
