I'm trying to build my Next.js project but it keeps giving me this error in the terminal:
Error: Build optimization failed: found page without a React Component as default export in
pages/components/context/Context
That's the React context API file, there isn't supposed to be any default export there. Is this a bug or what?
You should move your components outside the pages folder. pages/ should only be used for page components as Next.js routing is based on its structure.
Next.js has a file-system based router built on the concept of pages.
When a file is added to the pages directory it's automatically available as a route.
Even though the above is the default behaviour, you can configure your Next.js app to include non-page files in the pages directory.
To do so, you can modify the pageExtensions entry in the next.config.js file as shown below. Then rename your page components to have a file extension that includes .page (_document.page.js, _app.page.js, index.page.js, etc).
module.exports = {
pageExtensions: ['page.tsx', 'page.ts', 'page.jsx', 'page.js']
}
With this configuration, Next.js will ignore any file that doesn't contain .page for the purpose of building pages/API routes and routing.
