Inspector Component

This page is the Part.1 of configuration, we will add the Inspector UI component in your project that provider interaction on browser, like this:

Setup

At first install the package:

npm i -D react-dev-inspector

Then import the react-dev-inspector in your project entry file, like one of main.tsx, App.tsx or index.tsx:

import { createRoot } from 'react-dom/client'
import { Inspector } from 'react-dev-inspector'
import { App } from './App'
import './index.css'
 
createRoot(document.getElementById('root') as HTMLDivElement)
  .render(
    <React.StrictMode>
      <Inspector />
      <App />
    </React.StrictMode>,
  )

(opens in a new tab)

Now, we've completed the simplest setup way in this Part.1 🎉.

To begin developing your project, you'll gain access to the Inspector UI in the browser via default keyboard shortcuts:

• Ctrl + Shift + Command + C on macOS
• Ctrl + Shift + Alt + C on Windows / Linux

By default, clicking inspected element in the browser will trigger the <Inspector> to send an API network request to dev-server, that will call your local IDE/editor to open the source file.

For the next Part.2, you'll need to do set up a Middleware on Server-Side to handle these API requests.

Certainly, you also have the option to override these shortcuts by configuring the props of the <Inspector> component. For more advanced controls, refer to the Props section below.

Props

This section refers to the interface of InspectorProps (opens in a new tab) for <Inspector> component.

<Inspector
  keys={...}
  onInspectElement={...}
  onHoverElement={...}
  onClickElement={...}
  active={...}
  onActiveChange={...}
  disable={...}
/>

keys

• Type: keys?: string[] | null
• Default:
  ['Ctrl', 'Shift', 'Command', 'C'] on macOS
  ['Ctrl', 'Shift', 'Alt', 'C'] on other platforms

Activity toggle hotkeys for <Inspector> component, supported keys see: https://github.com/jaywcjlove/hotkeys#supported-keys (opens in a new tab)

Setting keys={null} explicitly means that disable use hotkeys to trigger it.

active

Added in: v2.0.0

Type: active?: boolean

If setting active prop, the Inspector will be a Controlled React Component, you need to control the true / false state to active the Inspector.

If not setting active prop, this only a Uncontrolled component that will activate/deactivate by hotkeys.

onActiveChange

Added in: v2.0.0

Type: onActiveChange?: (active: boolean) => void

Callback trigger by active state change, includes:

• hotkeys toggle, before activate/deactivate Inspector
• Escape / Click, before deactivate Inspector

Note: onActiveChange will NOT trigger by change of active prop key.

disable

Added in: v2.0.0

Type: disable?: boolean

Whether to disable all behavior include hotkeys listening or trigger.

inspectAgents

Added in: v2.1.0

• Type: inspectAgents?: InspectAgent<Element>[]

  interface InspectAgent (opens in a new tab)

• Default: built-in [new DomInspectAgent()]

  class DomInspectAgent (opens in a new tab)

Agent for get inspection info in different React renderer with user interaction.

onInspectElement

Added in: v2.0.0

• Type: onInspectElement?: (params: Required<InspectParams>) => void

  interface InspectParams (opens in a new tab))

• Default: built-in gotoServerEditor (opens in a new tab) util function

Callback when left-clicking on an element, with ensuring the source code info is found, the default gotoServerEditor callback will request the dev-server to open local IDE/editor from server-side.

You can also use the built-in gotoServerEditor util funtion in onInspectElement to get origin behavior (open local IDE on server-side), it looks like:

import { Inspector, gotoServerEditor } from 'react-dev-inspector'
 
<Inspector
  onInspectElement={({ codeInfo }) => {
    ... // your processing
 
    gotoServerEditor(codeInfo)
  }}
/>

Or simply use other built-in utils likes gotoVSCode, gotoVSCodeInsiders, gotoWebStorm to open IDE/editor by URL-scheme, which not need any server side configuration:

import { gotoVSCode, gotoVSCodeInsiders, gotoWebStorm } from 'react-dev-inspector'
 
<Inspector
  onInspectElement={gotoVSCode}
  // onInspectElement={gotoVSCodeInsiders}
  // onInspectElement={gotoWebStorm}
/>

onHoverElement

Type: onHoverElement?: (params: InspectParams) => void

Callback when hovering on an element

onClickElement

Type: onClickElement?: (params: InspectParams) => void

Callback when left-clicking on an element.

children

Type: children?: ReactNode

Any children of react nodes, to support usages like both of:

<Layout>
  <Inspector />
  <App />
</Layout>

and

<Layout>
  <Inspector>
    <App />
  </Inspector>
</Layout>

disableLaunchEditor

Deprecated after: v2.0.0

• Type: disableLaunchEditor?: boolean
• Default: true if setting onInspectElement callback, otherwise is false.

Whether to disable default behavior: "open local IDE when click on component".
