## Using with Next.js

@@ -115,36 +115,22 @@ The `getServerSideProps`, `getInitialProps`, and `getStaticProps` data hooks provided by Next.js do not allow you to transmit Javascript objects like Dates. It will error unless you convert Dates to strings, etc.

```js
import { useMemo } from 'react';
import superjson from 'superjson';
Install the library with your package manager of choice, e.g.:
export const getServerSideProps = async () => {
const products = [{ name: 'Hat', publishedAt: new Date(0) }];
```sh
yarn add -D babel-plugin-superjson-next
```
const dataString = superjson.stringify(products);
Add the plugin to your .babelrc. If you don't have one, create it.
return {
props: {
dataString,
},
};
};
export default function Page({ dataString }) {
const products = useMemo(() => superjson.parse(dataString), [dataString]);
return (
<div>
<h1>Products</h1>
{products.map(product => (
<p key={product.id}>
<span>Name: {product.name}</span>
{/* Note: publishedAt is an actual Date object! */}
<span>Published at: {product.publishedAt.toISOString()}</span>
</p>
))}
</div>
);
```js
{
"presets": ["next/babel"],
"plugins": [
...
"superjson-next" // 👈
]
}
```
Done! Now you can safely use all JS datatypes in your `getServerSideProps` / etc. .
