> JS implementation of DAG-JSON

# Install

```console
$ npm i @ipld/dag-json
```

## Browser `<script>` tag

Loading this module through a script tag will make its exports available as `IpldDagJson` in the global namespace.

```html
<script src="https://unpkg.com/@ipld/dag-json/dist/index.min.js"></script>
```

# Usage

`@ipld/dag-json` is designed to be used within multiformats but can be used separately. `encode()`, `decode()` are available as exports, as are `name` and `code` to match with the corresponding DAG-JSON [multicodec](https://github.com/multiformats/multicodec/).
