When it comes to handling server-side rendering, static-site generation, and code splitting in Next.js, there's a touch of magic involved. The unique aspect is that all this sorcery happens right within the /pages folder. It's worth noting that components residing in the /pages directory function slightly differently from typical React components. Here are some valuable tips that might just be the solution to your current dilemma.
1. Place your page components inside the /pages folder.
Components housed in this specific folder can have a default export (the component) along with named exports (such as the special Next.js functions like getStaticProps). Should Next.js detect these exported functions, it will proceed to execute them.
2. Reserve next/dynamic solely for dynamic imports.
Dynamic imports facilitate lazy loading, which has implications on both Next.js' automatic code-splitting and potentially server-side rendering capabilities. While I may not possess the full understanding of its inner workings, my hunch suggests that dynamically loading a Page component (given their uniqueness in Next.js) could be the source of the issue at hand. Personally, I tend to resort to dynamic imports only when dealing with third-party components that disrupt SSR, necessitating their exclusion from server-side rendering through dynamic importing.
Perhaps the simplest approach to tackle this would be:
within /pages/index.js:
import Example from '../path/to/example';
export default (props) => (
<div>
<p>My page component</p>
<Example />
</div>
);
export async function getStaticProps() {
return {
props: {
data: // ...
}
};
}
In the scenario above, you may incorporate dynamic imports too -- what holds significance is the immediate exportation of your Next.js-specific function straight from the file within /pages:
inside /pages/index.js:
import dynamic from 'next/dynamic';
const Example = dynamic(() => import('../components/example'));
export default (props) => (
<div>
<p>My page component</p>
<Example />
</div>
);
export async function getStaticProps() {
return {
props: {
data: // ...
}
};
}
To address the concern regarding "My getStaticProps function is in my example.js file, and my issue is that it is not being triggered.":
It's crucial to recognize that Next.js exclusively triggers a getStaticProps function if it's exported from a file within the /pages directory. If you intend to define your getStaticProps method outside of this directory, it's indeed feasible; however, you must import it into /pages and subsequently re-export it as follows:
within /components/example.js:
export default () => (
// ... component ...
);
export function getStaticProps() {
// ... function ...
};
furthermore, inside /pages/index.js:
import Example, { getStaticProps } from '../components/example';
export default Example;
export {
getStaticProps
}
This methodology should prove effective. Nevertheless, it's important to note that in this context, you cannot leverage dynamic imports for Example.
