## Usage

Install the package:

```

$ npm i @zerodevx/svelte-json-view

```

### Svelte

If you're using this in a Svelte app:

```html

  import { JsonView } from '@zerodevx/svelte-json-view'

  const json = { foo: 'bar' }

```

### Vanilla JS

For other applications with a bundler:

```js

// Import the compiled code from `/dist`

import { JsonView } from '@zerodevx/svelte-json-view/dist'

const app = new JsonView({

  target: document.body   // node to render into

})

app.$set({

  json: { foo: 'bar' },   // object to prettify

  ...                     // any other props

})

```

Or load via CDN:

```html

  ...

  

  

  

  

    const app = new JsonView({

      target: document.querySelector('#target'), // node to render into

      props: {

        json: { foo: 'bar' }, // object to prettify

        ...                   // any other props

      }

    })

  

  


```

## Theming

In general, use CSS variables.

| Name                           | Default        | Description                                   |

| ------------------------------ | -------------- | --------------------------------------------- |

| `--jsonPaddingLeft`            | `1rem`         | Amount of left padding to apply at each depth |

| `--jsonBorderLeft`             | `1px dotted`   | Style applied to left border for each depth   |

| `--jsonBracketColor`           | `currentcolor` | Colour for brackets `[`, `{`, `}` and `]`     |

| `--jsonBracketHoverBackground` | `#e5e7eb`      | Hover background for brackets                 |

| `--jsonSeparatorColor`         | `currentcolor` | Colour for separators `:` and `,`             |

| `--jsonKeyColor`               | `currentcolor` | Colour for keys                               |

| `--jsonValColor`               | `#9ca3af`      | Default colour for values                     |

| `--jsonValStringColor`         | `#059669`      | Colour for `string` values                    |

| `--jsonValNumberColor`         | `#d97706`      | Colour for `number` values                    |

| `--jsonValBooleanColor`        | `#2563eb`      | Colour for `boolean` values                   |

To apply your own font family (a monospaced font is recommended) or apply custom CSS var overrides,

try wrapping the component and applying these styles to the wrapper like so:

```html



  



  .wrap {

    font-family: monospace;

    font-size: 14px;

    --jsonBorderLeft: 2px dashed red;

    --jsonValColor: blue;

    ...

  }

```

## Props

| Name    | Type     | Default     | Description                      |

| ------- | -------- | ----------- | -------------------------------- |

| `json`  | `object` | `undefined` | Un-stringified object to display |

| `depth` | `number` | `Infinity`  | Initial expansion depth          |
