⚠️ Note: This package is deprecated. Use the browser plugin instead. Also note that with mobx-react@6 and higher the package should no longer be needed, see changelog ⚠️

DevTools for MobX to track the rendering behavior and data dependencies of your app.

MobX DevTools

The default position of the panel has been changed to bottom right. If you prefer top right like in the gif above, add position="topRight" to <DevTools />.

Installation

npm install --save-dev mobx-react-devtools

or

<script src="https://unpkg.com/mobx-react-devtools"></script>

Usage

Somewhere in your application, create a DevTools component:

import DevTools from 'mobx-react-devtools';

class MyApp extends React.Component {
  render() {
    return (
      <div>
        ...
        <DevTools />
      </div>
    );
  }
}

or

React.createElement(mobxDevtools.default)

Supported props:

  • highlightTimeout — number, default: 1500
  • noPanel — boolean, if set, do not render control panel, default: false
  • position — string (or object), topRight, bottomRight, bottomLeft or topLeft, default: bottomRight
  • className — string, className of control panel, default: not defined
  • style — object, inline style object of control panel, default: not defined

In order to be compatible with earlier versions of mobx-react-devtools it is also possible to assign position to an object containing inline styles. Using the dedicated style property is however recommended.

From there on, after each rendering a reactive components logs the following three metrics:

  1. Number of times the component did render so far
  2. The time spend in the render() method of a component
  3. The time spend from the start of the render() method until the changes are flushed to the DOM

For each component the color indicates roughly how long the coloring took. Rendering times are cumulative; they include time spend in the children

  • Green: less then 25 ms
  • Orange: less then 100 ms
  • Red: rendering for this component took more than 100ms

About log groups

Note that if logging is enabled, MobX actions and reactions will appear as collapsible groups inside the browsers console. Mind that any log statements that are printed during these (re)actions will appear inside those groups as well, so that you can exactly trace when they are triggered.

Configuration

import { configureDevtool } from 'mobx-react-devtools';

// Any configurations are optional
configureDevtool({
  // Turn on logging changes button programmatically:
  logEnabled: true,
  // Turn off displaying components updates button programmatically:
  updatesEnabled: false,
  // Log only changes of type `reaction`
  // (only affects top-level messages in console, not inside groups)
  logFilter: change => change.type === 'reaction',
});

There are also aliases for turning on/off devtools buttons:

import { setLogEnabled, setUpdatesEnabled, setGraphEnabled } from 'mobx-react-devtools';

setLogEnabled(true); // same as configureDevtool({ logEnabled: true });
setUpdatesEnabled(false); // same as configureDevtool({ updatesEnabled: false });
setGraphEnabled(false); // same as configureDevtool({ graphEnabled: false });

Custom panel design

import DevTools, { GraphControl, LogControl, UpdatesControl } from 'mobx-react-devtools';

class MyNiceButton extends React.Component {
  render() {
    const { active, onToggle, children } = this.props;
    return (
      <button onClick={onToggle}>
        {children}
        {active ? ' on' : ' off'}
      </button>
    );
  }
}

class MyApp extends React.Component {
  render() {
    return (
      <div>

        {/* Include somewhere with `noPanel` prop. Is needed to display updates and modals */}
        <DevTools noPanel />

        <div className="my-custom-devtools-panel-design">
          <GraphControl>
            {/* Must have only one child that takes props: `active` (bool), `onToggle` (func) */}
            <MyNiceButton>Graph</MyNiceButton>
          </GraphControl>
          <LogControl>
            {/* Must have only one child that takes props: `active` (bool), `onToggle` (func) */}
            <MyNiceButton>Log</MyNiceButton>
          </LogControl>
          <UpdatesControl>
            {/* Must have only one child that takes props: `active` (bool), `onToggle` (func) */}
            <MyNiceButton>Updates</MyNiceButton>
          </UpdatesControl>
        </div>
      </div>
    );
  }
}

Roadmap

  • Be able to turn dev-tools on and off at runtime
  • Select and log dependency tree of components
