## Key features

- 🍱 Reliable serialization and deserialization
- 🔐 Type safety with autocompletion
- 🐾 Negligible runtime footprint
- 💫 Framework agnostic
- 🛠 Perfect fix for Next.js's serialisation limitations in `getServerSideProps` and `getInitialProps`

## Backstory

At [Blitz](https://github.com/blitz-js/blitz), we have struggled with the limitations of JSON. We often find ourselves working with `Date`, `Map`, `Set` or `BigInt`, but `JSON.stringify` doesn't support any of them without going through the hassle of converting manually!

Superjson solves these issues by providing a thin wrapper over `JSON.stringify` and `JSON.parse`.

## Getting started

Install the library with your package manager of choice, e.g.:

```
yarn add superjson
```

## Basic Usage

The easiest way to use Superjson is with its `stringify` and `parse` functions. If you know how to use `JSON.stringify`, you already know Superjson!

Easily stringify any expression you’d like:

```js
import superjson from 'superjson';

const jsonString = superjson.stringify({ date: new Date(0) });

// jsonString === '{"json":{"date":"1970-01-01T00:00:00.000Z"},"meta":{"values":{date:"Date"}}}'
```

And parse your JSON like so:

```js
const object = superjson.parse<
{ date: Date }
>(jsonString);

// object === { date: new Date(0) }
```

## Advanced Usage

For cases where you want lower level access to the `json` and `meta` data in the output, you can use the `serialize` and `deserialize` functions.

One great use case for this is where you have an API that you want to be JSON compatible for all clients, but you still also want to transmit the meta data so clients can use superjson to fully deserialize it.

For example:

```js
const object = {
  normal: 'string',
  timestamp: new Date(),
  test: /superjson/,
};

const { json, meta } = superjson.serialize(object);

/*
json = {
  normal: 'string',
  timestamp: "2020-06-20T04:56:50.293Z",
  test: "/superjson/",
};

// note that `normal` is not included here; `meta` only has special cases
meta = {
  values: {
    timestamp: ['Date'],
    test: ['regexp'],
  }
};
*/
```

## Using with Next.js

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.

Thankfully, Superjson is a perfect tool to bypass that limitation!

### Next.js SWC Plugin (experimental, v13 or above)

Next.js SWC plugins are [experimental](https://nextjs.org/docs/advanced-features/compiler#swc-plugins-experimental), but promise a significant speedup.
To use the [SuperJSON SWC plugin](https://github.com/blitz-js/next-superjson-plugin), install it and add it to your `next.config.js`:

```sh
yarn add next-superjson-plugin
```

```js
// next.config.js
module.exports = {
  experimental: {
    swcPlugins: [
      [
        'next-superjson-plugin',
        {
          excluded: [],
        },
      ],
    ],
  },
};
```

### Next.js (stable Babel transform)

Install the library with your package manager of choice, e.g.:

```sh
yarn add babel-plugin-superjson-next
```

Add the plugin to your .babelrc. If you don't have one, create it.

```js
{
  "presets": ["next/babel"],
  "plugins": [
    ...
    "superjson-next" // 👈
  ]
}
```

Done! Now you can safely use all JS datatypes in your `getServerSideProps` / etc. .

## API

### serialize

Serializes any JavaScript value into a JSON-compatible object.

#### Examples

```js
const object = {
  normal: 'string',
  timestamp: new Date(),
  test: /superjson/,
};

const { json, meta } = serialize(object);
```

Returns **`json` and `meta`, both JSON-compatible values.**

## deserialize

Deserializes the output of Superjson back into your original value.

#### Examples

```js
const { json, meta } = serialize(object);

deserialize({ json, meta }, { inPlace: true });
```

Options

- `inPlace: boolean`
  - Default: `false`
  - Mutate the input json object in place instead of returning a deep copy
  - `inPlace: true` will be much more performant on large objects if it's safe to mutate it

Returns **`your original value`**.

### stringify

Serializes and then stringifies your JavaScript value.

#### Examples

```js
const object = {
  normal: 'string',
  timestamp: new Date(),
  test: /superjson/,
};

const jsonString = stringify(object);
```

Returns **`string`**.

### parse

Parses and then deserializes the JSON string returned by `stringify`.

#### Examples

```js
const jsonString = stringify(object);

parse(jsonString);
```

Returns **`your original value`**.

---

Superjson supports many extra types which JSON does not. You can serialize all these:

| type        | supported by standard JSON? | supported by Superjson? |
| ----------- | --------------------------- | ----------------------- |
| `string`    | ✅                          | ✅                      |
| `number`    | ✅                          | ✅                      |
| `boolean`   | ✅                          | ✅                      |
| `null`      | ✅                          | ✅                      |
| `Array`     | ✅                          | ✅                      |
| `Object`    | ✅                          | ✅                      |
| `undefined` | ❌                          | ✅                      |
| `bigint`    | ❌                          | ✅                      |
| `Date`      | ❌                          | ✅                      |
| `RegExp`    | ❌                          | ✅                      |
| `Set`       | ❌                          | ✅                      |
| `Map`       | ❌                          | ✅                      |
| `Error`     | ❌                          | ✅                      |
| `URL`       | ❌                          | ✅                      |

## Recipes

SuperJSON by default only supports built-in data types to keep bundle-size as low as possible.
Here are some recipes you can use to extend to non-default data types.

Place them in some central utility file and make sure they're executed before any other `SuperJSON` calls.
In a Next.js project, `_app.ts` would be a good spot for that.

### `Decimal.js` / `Prisma.Decimal`

```ts
import { Decimal } from 'decimal.js';

SuperJSON.registerCustom<Decimal, string>(
  {
    isApplicable: (v): v is Decimal => Decimal.isDecimal(v),
    serialize: v => v.toJSON(),
    deserialize: v => new Decimal(v),
  },
  'decimal.js'
);
```
