Routing in Next.js is based on the file system, so ./pages/index.js
maps to the /
route and
./pages/about.js
would map to /about
.
The ./static
directory maps to /static
in the next
server, so you can put all your
other static resources like images or compiled CSS in there.
Out of the box, we get:
- Automatic transpilation and bundling (with webpack and babel)
- Hot code reloading
- Server rendering and indexing of
./pages
- Static file serving.
./static/
is mapped to/static/

In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any errors in the console.
Builds the app for production to the .next
folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
Starts the application in production mode. The application should be compiled with `next build` first.
See the section in Next docs about deployment for more information.
You can fetch data in pages
components using getInitialProps
like this:
const Page = props => <div>Next stars: {props.stars}</div>;
Page.getInitialProps = async ({ req }) => {
const res = await fetch('https://api.github.com/repos/zeit/next.js');
const json = await res.json();
const stars = json.stargazers_count;
return { stars };
};
export default Page;
For the initial page load, getInitialProps
will execute on the server only. getInitialProps
will only be executed on the client when navigating to a different route via the Link
component or using the routing APIs.
Note: getInitialProps
can not be used in children components. Only in pages
.
