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().
  • uploadToServer 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 any other crashReporter APIs and in each process (main/renderer) from which you want to collect crash reports. You can pass different options to crashReporter.start when calling from different processes.

Note: On Windows and Linux, Electron uses breakpad for crash collection and reporting. Crashes can be collected from the main and renderer process, but not from the child processes created via the child_process module.

Note: On macOS, Electron uses a new crashpad client for crash collection and reporting. Crashes can be collected from the main, renderer and any of the child processes created via the child_process module. If you want to enable crash reporting, initializing crashpad from the main process using crashReporter.start is required regardless of which process you want to collect crashes from. Once initialized this way, the crashpad handler collects crashes from all processes. You still have to call crashReporter.start from the renderer process, otherwise crashes from renderer processes will get reported without companyName, productName or any of the extra information.

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.getUploadToServer() macOS

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

Note: This API can only be called from the main process.

crashReporter.setUploadToServer(uploadToServer) macOS

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

This would normally be controlled by user preferences. This has no effect if called before start is called.

Note: This API can only be called 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.
