react-devtools-core

A standalone React DevTools implementation.

This is a low-level package.
If you're looking for the Electron app you can run, use react-devtools package instead.

Exports

require('react-devtools-core').connectToDevTools(options)

This is similar to require('react-devtools') in another package but providing more control.
Unlike require('react-devtools'), it doesn't connect immediately, but exports a function.

Run connectToDevTools() in the same context as React to set up a connection to DevTools.
Make sure this runs before any react, react-dom, or react-native imports.

The options object may contain:

  • host (string), defaults to 'localhost'.
  • port (number), defaults to 8097.
  • resolveRNStyle (function), used by RN and null by default.

None of the options are required.

require('react-devtools-core/standalone')

Lets you render DevTools into a DOM node and have it listen to connections.

For example:

require('react-devtools-core/standalone')
  .setContentDOMNode(document.getElementById('container'))
  .startServer(port);

You can check the Electron shell in react-devtools package for a complete integration example.

You can’t perform that action at this time.
