# 🔄 [express-superjson](https://npmjs.com/package/express-superjson)

Express middleware that seamlessly integrates [Superjson](https://github.com/blitz-js/superjson) into your Express.js applications, enabling automatic handling of JavaScript built-in types in HTTP responses.

## 🚀 Installation

Install the package using your preferred package manager. Here's an example using `pnpm`:

```bash

pnpm add superjson express-superjson

```

## 📝 Example Usage

```ts

import express from 'express';

import superjsonMiddleware from 'express-superjson';

const app = express();

app.use(express.json());

// This middleware must be registered after `express.json()` middleware.

app.use(superjsonMiddleware());

app.get('/', (req, res) => {

  res.json({ date: new Date() });

});

app.listen(3000, () => console.log('Application is running on port 3000.'));

```

Send a **GET** request to `http://localhost:3000` and you'll receive a **Superjson** response like below:

```

{

  "json": {

    "date": "2023-01-01T00:00:00.000Z"

  },

  "meta": {

    "values": {

      "date": ["Date"]

    }

  }

}

```

## 🧪 Code Coverage and Tests
