Getting Started

Add the Toaster to your app first. It will take care of rendering all notifications emitted. Now you can trigger toast() from anywhere!

import toast, { Toaster } from 'react-hot-toast';

const notify = () => toast('Here is your toast.');

const App = () => {
  return (
    <div>
      <button onClick={notify}>Make me a toast</button>
      <Toaster />
    </div>
  );
};

Quick facts

Common pairings

Packages this one expects to find in the same project. Each is also a Sourcemap Explorer detection target.

How Sourcemap Explorer detects react-hot-toast

We catch react-hot-toast from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/react-hot-toast/ paths inside the JavaScript sourcemap's sources[] array — that's the canonical signal. When the matching package.json is also captured in sourcesContent[], we read the exact version field — patch number included. No regex guessing, no version inference.

1. 1

   Confirm the site exposes sourcemaps

   In DevTools Network, check the response headers of any application script for `SourceMap` or `X-SourceMap`. Failing that, fetch the script's last 4 KB and look for a `//# sourceMappingURL=` comment.

2. 2

   Find the package in the bundle

   Open DevTools → Network → reload. Click any application script and look at its sourcemap. Inside, search `sources[]` for entries matching `node_modules/react-hot-toast/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/react-hot-toast/package.json` gives you the exact installed version.

3. 3

   Read the version directly from package.json

   Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/react-hot-toast/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.
