Catch unhandled errors and promise rejections in your Electron app

You can use this module directly in both the main and renderer process.

npm install electron-unhandled

Requires Electron 30 or later.

import unhandled from 'electron-unhandled';

unhandled();

You probably want to call this both in the main process and any renderer processes to catch all possible errors.

Note: At minimum, this function must be called in the main process.

Type: object

Note: Options can only be specified in the main process.

Type: Function
Default: console.error

Custom logger that receives the error.

Can be useful if you for example integrate with Sentry.

Type: boolean
Default: Only in production

Present an error dialog to the user.

Type: Function
Default: undefined

When specified, the error dialog will include a Report… button, which when clicked, executes the given function with the error as the first argument.

import unhandled from 'electron-unhandled';
import {openNewGitHubIssue} from 'electron-util';
import {debugInfo} from 'electron-util/main';

unhandled({
	reportButton: error => {
		openNewGitHubIssue({
			user: 'sindresorhus',
			repo: 'electron-unhandled',
			body: `
## Node.js error stack

\`\`\`
${stack}
\`\`\`

## Node.js debug info

${debugInfo()}`
		});
	}
});

Example of how the GitHub issue will look like.

Log an error. This does the same as with caught unhandled errors.

It will use the same options specified in the unhandled() call or the defaults.

import {logError} from 'electron-unhandled';

logError(new Error('🦄'));

Type: Error

The error to log.

Type: object

Type: string
Default: ${appName} encountered an error

The title of the error dialog.
