@json-render/devtools-svelte

Svelte 5 adapter for the json-render devtools panel. Read `skills/devtools/SKILL.md` for the shared panel capabilities, props, docking behavior, and server-side stream taps.

Install

npm install @json-render/devtools @json-render/devtools-svelte

Mount the panel

Mount `JsonRenderDevtools` inside the existing Svelte json-render provider:

<script>
  import { JsonRenderDevtools } from "@json-render/devtools-svelte";
</script>

<JSONUIProvider {registry}>
  <Renderer {spec} {registry} />
  <JsonRenderDevtools {spec} {catalog} {messages} />
</JSONUIProvider>

The component renders nothing in production builds. The panel provides the shared devtools controls, including the `Ctrl`/`Cmd` + `Shift` + `J` shortcut. Keep server-side stream instrumentation in `@json-render/devtools`.
