Readme
redbox-react
The red box (aka red screen of death) renders an error in this “pretty” format:
Usage
import RedBox from 'redbox-react'
const e = new Error('boom')
const box = <RedBox error={e} />
Here is a more useful, full-fleged example:
/* global __DEV__ */
import React from 'react'
import { render } from 'react-dom'
import App from './components/App'
const root = document.getElementById('root')
if (__DEV__) {
const RedBox = require('redbox-react').default
try {
render(<App />, root)
} catch (e) {
render(<RedBox error={e} />, root)
}
} else {
render(<App />, root)
}
What Is This Good For?
An error that's only in the console is only half the fun. Now you can use all the wasted space where your app would be if it didn’t crash to display the error that made it crash.
Please use this in development only.
Will this catch errors for me?
No. This is only a UI component for rendering errors and their stack traces. It is intended to be used with with other existing solutions that automate the error catching for you. See the list at the top of this document or take a look at the examples.
Optional Props
The RedBox
component takes a couple of props that you can use to
customize its behaviour:
editorScheme
[?string]
If a filename in the stack trace is local, the component can create the link to open your editor using this scheme eg:
subl
to createsubl://open?url=file:///filename
.- or
vscode
to createvscode://file/filename
.
useLines
[boolean=true]
Line numbers in the stack trace may be unreliable depending on the type of sourcemaps. You can choose to not display them with this flag.
useColumns
[boolean=true]
Column numbers in the stack trace may be unreliable depending on the type of sourcemaps. You can choose to not display them with this flag.
style
[?object]
Allows you to override the styles used when rendering the various parts of the component. It will be shallow-merged with the default styles.
If you’re using [react-transform-catch-errors] you can add these
options to your .babelrc
through the imports
property.
Sourcemaps With Webpack
If you’re using Webpack you can get
accurate filenames in the stacktrace by setting the
output.devtoolModuleFilenameTemplate
settings to /[absolute-resource-path]
.
It's recommended to set the devtool
setting to 'eval'
.
