## Using NPM or Yarn

```bash
$ npm install vue-json-pretty --save
```

```bash
$ yarn add vue-json-pretty
```

## Use Vue2

```bash
$ npm install vue-json-pretty@v1-latest --save
```

## Usage

The CSS file is included separately and needs to be imported manually. You can either import CSS globally in your app (if supported by your framework) or directly from the component.

```vue
<template>
  <div>
    <vue-json-pretty :data="{ key: 'value' }" />
  </div>
</template>

<script>
import VueJsonPretty from 'vue-json-pretty';
import 'vue-json-pretty/lib/styles.css';

export default {
  components: {
    VueJsonPretty,
  },
};
</script>
```

## Use Nuxt.js

1. In `plugins/vue-json-pretty.js`

```
import Vue from 'vue'
import VueJsonPretty from 'vue-json-pretty'

Vue.component("vue-json-pretty", VueJsonPretty)
```

2. In `nuxt.config.js`

```js
css: [
  'vue-json-pretty/lib/styles.css'
],
plugins: [
  '@/plugins/vue-json-pretty'
],
```
