crashReporter

Submit crash reports to a remote server.

Process: Main, Renderer

The following is an example of automatically submitting a crash report to a remote server:

const {crashReporter} = require('electron')

crashReporter.start({
  productName: 'YourName',
  companyName: 'YourCompany',
  submitURL: 'https://your-domain.com/url-to-submit',
  autoSubmit: true
})

For setting up a server to accept and process crash reports, you can use following projects:

• socorro
• mini-breakpad-server

Crash reports are saved locally in an application-specific temp directory folder. For a productName of YourName, crash reports will be stored in a folder named YourName Crashes inside the temp directory. You can customize this temp directory location for your app by calling the app.setPath('temp', '/my/custom/temp') API before starting the crash reporter.

Methods

The crashReporter module has the following methods:

crashReporter.start(options)

• options Object
  • companyName String (optional)
  • submitURL String - URL that crash reports will be sent to as POST.
  • productName String (optional) - Defaults to app.getName().
  • shouldUpload Boolean (optional) macOS - Whether crash reports should be sent to the server Default is true.
  • ignoreSystemCrashHandler Boolean (optional) - Default is false.
  • extra Object (optional) - An object you can define that will be sent along with the report. Only string properties are sent correctly, Nested objects are not supported.

You are required to call this method before using other crashReporter APIs.

Note: On macOS, Electron uses a new crashpad client, which is different from breakpad on Windows and Linux. To enable the crash collection feature, you are required to call the crashReporter.start API to initialize crashpad in the main process and in each renderer process from which you wish to collect crash reports.

crashReporter.getLastCrashReport()

Returns CrashReport:

Returns the date and ID of the last crash report. If no crash reports have been sent or the crash reporter has not been started, null is returned.

crashReporter.getUploadedReports()

Returns CrashReport[]:

Returns all uploaded crash reports. Each report contains the date and uploaded ID.

crashReporter.getShouldUpload() macOS

Returns Boolean - Whether reports should be submitted to the server. Set through the start method or setShouldUpload.

NOTE: This API can only be used from the main process

crashReporter.setShouldUpload(shouldUpload) macOS

• shouldUpload Boolean macOS - Whether reports should be submitted to the server

This would normally be controlled by user preferences.

NOTE: This API can only be used from the main process

Crash Report Payload

The crash reporter will send the following data to the submitURL as a multipart/form-data POST:

• ver String - The version of Electron.
• platform String - e.g. 'win32'.
• process_type String - e.g. 'renderer'.
• guid String - e.g. '5e1286fc-da97-479e-918b-6bfb0c3d1c72'
• _version String - The version in package.json.
• _productName String - The product name in the crashReporter options object.
• prod String - Name of the underlying product. In this case Electron.
• _companyName String - The company name in the crashReporter options object.
• upload_file_minidump File - The crash report in the format of minidump.
• All level one properties of the extra object in the crashReporter options object.
