# crashReporter
|
|
|
|
> Submit crash reports to a remote server.
|
|
|
|
Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)
|
|
|
|
The following is an example of automatically submitting a crash report to a
|
|
remote server:
|
|
|
|
```javascript
|
|
const {crashReporter} = require('electron')
|
|
|
|
crashReporter.start({
|
|
productName: 'YourName',
|
|
companyName: 'YourCompany',
|
|
submitURL: 'https://your-domain.com/url-to-submit',
|
|
uploadToServer: true
|
|
})
|
|
```
|
|
|
|
For setting up a server to accept and process crash reports, you can use
|
|
following projects:
|
|
|
|
* [socorro](https://github.com/mozilla/socorro)
|
|
* [mini-breakpad-server](https://github.com/electron/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) - 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 and the property names and values must be less than 64 characters long.
|
|
* `crashesDirectory` String (optional) - Directory to store the crashreports temporarily (only used when the crash reporter is started via `process.crashReporter.start`).
|
|
|
|
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** Child processes created via the `child_process` module will not have access to the Electron modules.
|
|
Therefore, to collect crash reports from them, use `process.crashReporter.start` instead. Pass the same options as above
|
|
along with an additional one called `crashesDirectory` that should point to a directory to store the crash
|
|
reports temporarily. You can test this out by calling `process.crash()` to crash the child process.
|
|
|
|
**Note:** To collect crash reports from child process in Windows, you need to add this extra code as well.
|
|
This will start the process that will monitor and send the crash reports. Replace `submitURL`, `productName`
|
|
and `crashesDirectory` with appropriate values.
|
|
|
|
**Note:** If you need send additional/updated `extra` parameters after your
|
|
first call `start` you can call `setExtraParameter` on macOS or call `start`
|
|
again with the new/updated `extra` parameters on Linux and Windows.
|
|
|
|
```js
|
|
const args = [
|
|
`--reporter-url=${submitURL}`,
|
|
`--application-name=${productName}`,
|
|
`--crashes-directory=${crashesDirectory}`
|
|
]
|
|
const env = {
|
|
ELECTRON_INTERNAL_CRASH_SERVICE: 1
|
|
}
|
|
spawn(process.execPath, args, {
|
|
env: env,
|
|
detached: true
|
|
})
|
|
```
|
|
|
|
**Note:** On macOS, Electron uses a new `crashpad` client for crash collection and reporting.
|
|
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 or child process, otherwise crashes from
|
|
them will get reported without `companyName`, `productName` or any of the `extra` information.
|
|
|
|
### `crashReporter.getLastCrashReport()`
|
|
|
|
Returns [`CrashReport`](structures/crash-report.md):
|
|
|
|
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[]`](structures/crash-report.md):
|
|
|
|
Returns all uploaded crash reports. Each report contains the date and uploaded
|
|
ID.
|
|
|
|
### `crashReporter.getUploadToServer()` _Linux_ _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)` _Linux_ _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.
|
|
|
|
### `crashReporter.addExtraParameter(key, value)` _macOS_
|
|
|
|
* `key` String - Parameter key, must be less than 64 characters long.
|
|
* `value` String - Parameter value, must be less than 64 characters long.
|
|
|
|
Set an extra parameter to be sent with the crash report. The values
|
|
specified here will be sent in addition to any values set via the `extra` option when `start` was called. This API is only available on macOS, if you need to add/update extra parameters on Linux and Windows after your first call to `start` you can call `start` again with the updated `extra` options.
|
|
|
|
### `crashReporter.removeExtraParameter(key)` _macOS_
|
|
|
|
* `key` String - Parameter key, must be less than 64 characters long.
|
|
|
|
Remove a extra parameter from the current set of parameters so that it will not be sent with the crash report.
|
|
|
|
### `crashReporter.getParameters()`
|
|
|
|
See all of the current parameters being passed to the crash reporter.
|
|
|
|
## 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.
