sentry-javascript-lite
An extension for Sentry to expand raw javascript stack traces on the server, rather than the client. Allows for a lighter client.
Install
Install the package via pip:
pip install sentry-javascript-lite
This plugin includes all of the functionality of the builtin Javascript plugin. It is redundant to have both enabled.
Usage
The plugin looks for an extra field rawstack in the event data. It then attempts to expand this field into a Sentry stacktrace. This allows clients to simply submit the stack property provided with a browser exception.
Example client usage:
/** @param {Error} e */
function ExceptionLogger(e) {
var data = {
'project': 2,
'logger': 'my-custom-logger',
'platform': 'javascript',
'level': 4,
'request': {
'url': '' + location.href,
'headers': {
'User-Agent': navigator.userAgent
}
},
'exception': {
'type': e.name,
'value': e.message
},
'message': e.message,
'extra': {
'rawstack': e.stacktrace || e.stack
}
};
if (e['cause']) {
data['cause'] = e['cause'];
}
if (e['culprit']) {
data['culprit'] = e['culprit'];
}
var dataString = JSON.stringify(data);
var endpoint = endpointParsedFromDsn +
'?sentry_version=4&sentry_client=' +
encodeURIComponent(data['logger']) +
'&sentry_key=' + apikey +
'&sentry_data=' + encodeURIComponent(dataString);
var xhr = new XMLHttpRequest();
if ('withCredentials' in xhr) {
xhr.open('GET', endpoint, true);
xhr.send();
} else {
(new Image())['src'] = endpoint;
}
)Note: The stack or stacktrace property on browser Error objects is only provided by modern browsers. For older browser support, use the official raven-js client.
