Submit crash reports to a remote server.
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',
uploadToServer: true
})
For setting up a server to accept and process crash reports, you can use following projects:
Or use a 3rd party hosted solution:
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.
The crashReporter
module has the following methods:
options
ObjectcompanyName
String (optional)submitURL
String - URL that crash reports will be sent to as POST.productName
String (optional) - Defaults toapp.getName()
.uploadToServer
Boolean (optional) - Whether crash reports should be sent to the server Default istrue
.ignoreSystemCrashHandler
Boolean (optional) - Default isfalse
.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 viaprocess.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 addExtraParameter
on macOS or call start
again with the new/updated extra
parameters on Linux and Windows.
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.
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.
Returns CrashReport[]
:
Returns all uploaded crash reports. Each report contains the date and uploaded ID.
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.
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.
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.
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.
See all of the current parameters being passed to the crash reporter.
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 inpackage.json
._productName
String - The product name in thecrashReporter
options
object.prod
String - Name of the underlying product. In this case Electron._companyName
String - The company name in thecrashReporter
options
object.upload_file_minidump
File - The crash report in the format ofminidump
.- All level one properties of the
extra
object in thecrashReporter
options
object.
