Sanitize Network Data

Control how data is passed in network requests or responses

Sanitize a network request

requestSanitizer - Function

optional

Use requestSanitizer to scrub sensitive data from network requests or to ignore request/response pairs.

To ignore a request/response pair return null from the requestSanitizer. You can also redact fields on the request object by modifying the object. Make sure that you still return the modified request from the function:

// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    requestSanitizer: request => {
      // if the url contains 'ignore'
      if (request.url.toLowerCase().indexOf('ignore') !== -1) {
        // ignore the request response pair
        return null;
      }
      
      // otherwise log the request normally
      return request;
    },
  },
});
// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    requestSanitizer: request => {
      // if the url contains 'ignore'
      if (request.url.toLowerCase().indexOf('ignore') !== -1) {
        // scrub out the body
        request.body = null;
      }
        
      return request;
    },
  },
});
// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    requestSanitizer: request => {
      request.headers['x-auth-token'] = null;
      return request;
    },
  },
});
// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    requestSanitizer: request => {
      if (request.headers['x-auth-token']) {
        request.headers['x-auth-token'] = '';
      }
      
      return request;
    },
  },
});

Sanitize a network response

responseSanitizer - Function

optional

Use the responseSanitizer to redact sensitive data from network response. Return null from the function to redact all response fields and only record timing data.

// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    responseSanitizer: (response) => {
      if (response.body?.includes('<field to redact>')) {
        delete response.body;
      }
      return response;
    },
  },
});
// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    responseSanitizer: response => {
      return null;
    },
  },
});
if (response.body.**field_to_delete**) {
  delete response.body.**field_to_delete**;
}
return response
if (response.body.**field_to_hide**) {
  response.body.**field_to_hide** = "**redacted**";
}
return response

Joshua Bailey, a LogRocket user, contributed a plugin for more easily sanitizing data from network requests and responses. Check it out here: https://github.com/LogRocket/logrocket-fuzzy-search-sanitizer

Disable recording of network data

isEnabled - Boolean

optional (default - true)

If you wish to disable all network data recording, you may set isEnabled to false.

// Add this to your existing init call, do not call init twice!
LogRocket.init(YOUR_APP_ID, {
  network: {
    isEnabled: false,
  },
});

Sanitizing headers and bodies to maintain timing and error data

When possible, we recommend using the requestSanitizer and responseSanitizer to remove all headers and bodies, instead of isEnabled: false. Sanitizing the headers and bodies specifically will allow LogRocket to still detect failed network requests, network errors, and slow network requests.
