svelte-json-view
View JSON data prettily.
Display JSON data in a tree-like expandable view. Use as a Svelte component or in Vanilla JS.
Here's a demo.
Usage
Install the package:
$ npm i @zerodevx/svelte-json-viewSvelte
If you're using this in a Svelte app:
<script>
import { JsonView } from '@zerodevx/svelte-json-view'
const json = { foo: 'bar' }
</script>
<JsonView {json} />Vanilla JS
For other applications with a bundler:
// 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:
<head>
...
<!-- Load `JsonView` from CDN -->
<script defer src="https://cdn.jsdelivr.net/npm/@zerodevx/svelte-json-view@1"></script>
<!-- Register the view -->
<script type="module">
const app = new JsonView({
target: document.querySelector('#target'), // node to render into
props: {
json: { foo: 'bar' }, // object to prettify
... // any other props
}
})
</script>
</head>
<body>
<div id="target"></div>
</body>Theming
In general, use CSS variables.

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:
<div class="wrap">
<JsonView {json} />
</div>
<style>
.wrap {
font-family: monospace;
font-size: 14px;
--jsonBorderLeft: 2px dashed red;
--jsonValColor: blue;
...
}
</style>Props
