Usage

When using raven.js, it's common to add server level information for debugging purposes. We can use aws-instance-metadata to do just that. In order to tag all future error messages with the instance ID, we could do:

const raven = require('raven').Client(/* configuration omitted */);
const awsInstanceMetadata = require('aws-instance-metadata');

awsInstanceMetadata.fetch('instance-id').then((instanceId) => {
  raven.setTagsContext({
    instanceId: instanceId
  });
}, console.error);
