The Problem

You want to see console errors directly on pages without opening DevTools during development when developing for React Native for Web, like React Native's LogBox.

The Solution

react-native-web-log-box implements React Native's LogBox and can be used as a drop-in replacement.

Most of the code is taken directly from React Native's codebase and has been carefully adjusted to work on the Web. Ported features include parsing and formatting error messages to prevent over-showing similar errors that happen in succession.

Installation

yarn add react-native-web-log-box

or

npm install react-native-web-log-box

Setup

react-native-web-log-box works across Web, iOS and Android. Expo projects (Managed and Bare Workflow) are also supported.

When targeting iOS and Android, React Native's native implementation is used.

import * as React from 'react'
import { LogBox, LogBoxNotification } from 'react-native-web-log-box'

if (process.env.NODE_ENV !== 'production') {
  LogBox.ignoreLogs(['Keywords or regexes ignore'])
  LogBox.install()
}

function App() {
  return (
    <>
      {/* Put your app components before <LogBoxNotification />  */}
      <LogBoxNotification />
    </>
  )
}

LogBox is designed with tree-shaking in mind and will be erased on production builds.

For general information on React Native's LogBox, please refer to API documentation.

Limitations

Only console errors and warnings are captured in react-native-web-log-box and fullscreen error overlays are not implemented. You can open DevTools to see full errors and warnings.

Frameworks such as Next.js, Expo for Web and Create React App already capture uncaught exceptions and display in-built full-screen error overlays, so please use them for exceptions.
