How to deploy a Next.js build

Jul 20, 2025

✅ General Build & Deploy Steps (Any Platform)

Run this in the root of your project:

npm run build

This generates the .next/ directory with optimized output.

You can test the production build:

npm start

Make sure your package.json has this script:

"start": "next start"

Vercel is made by the creators of Next.js.

✔️ Auto builds, SSR, ISR, and Edge Functions supported out-of-the-box

If you're self-hosting with a custom server:

npm run build

npm start

Make sure next, react, and react-dom are in your dependencies (not devDependencies).
Deploy to your server (via SSH, Docker, etc.)

Example Dockerfile:

FROM node:18-alpine

WORKDIR /app
COPY . .

RUN npm install
RUN npm run build

EXPOSE 3000
CMD ["npm", "start"]

Then build and run:

docker build -t my-next-app .
docker run -p 3000:3000 my-next-app

If your app doesn't use SSR, you can export a static version:

next export

This creates an out/ folder. You can then host it on:

But SSR, API routes, and dynamic rendering won’t work in this mode.
