Example of logs in browser's conosle

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { RecoilRoot } from "recoil";
import RecoilLogger from 'recoil-logger'

ReactDOM.render(
  <React.StrictMode>
    <RecoilRoot>
      <RecoilLogger />
      <App />
    </RecoilRoot>
  </React.StrictMode>,
  document.getElementById('root')
);

Install

npm install --save-dev recoil-logger

or

yarn add --dev recoil-logger

Now you could add RecoilLogger to your app:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { RecoilRoot } from "recoil";
import RecoilLogger from 'recoil-logger'

ReactDOM.render(
  <React.StrictMode>
    <RecoilRoot>
+      <RecoilLogger /> {/* Please add this line inside `RecoilRoot` scope */}
      <App />
    </RecoilRoot>
  </React.StrictMode>,
  document.getElementById('root')
);

After this you can see the events on each atom in browser's console:

But to see the values you need to add persistence_UNSTABLE key to atom properties:

const counterState = atom({
  key: "count",
  default: 0,
+  persistence_UNSTABLE: {
+    type: 'log'
+  },
});

The key type can has any value but not none (by default it is none).
