This module provides a set of standard object serializers for the Pino logger.
Serializes an Error
like object. Returns an object:
{
type: 'string', // The name of the object's constructor.
message: 'string', // The supplied error message.
stack: 'string' // The stack when the error was generated.
}
Any other extra properties, e.g. statusCode
, that have been attached to the
object will also be present on the serialized object.
Used internally by Pino for general response logging. Returns an object:
{
res: {}
}
Where res
is the response
as serialized by the standard response serializer.
Used internall by Pino for general request logging. Returns an object:
{
req: {}
}
Where req
is the request
as serialized by the standard request serializer.
The default request
serializer. Returns and object:
{
id: 'string', // Defaults to `undefined`, unless there is an `id` property
// already attached to the `request` object or to the `request.info`
// object. Attach a synchronous function
// to the `request.id` that returns an identifier to have
// the value filled.
method: 'string',
url: 'string', // the request pathname (as per req.url in core HTTP)
headers: Object,
remoteAddress: 'string',
remotePort: Number,
raw: Object // Non-enumerable, i.e. will not be in the output, original
// request object. This is available for subsequent serializers
// to use. In cases where the `request` input already has
// a `raw` property this will be `request.raw` instead of the original
// request
}
The default response
serializer. Returns an object:
{
statusCode: Number,
header: Array, // The list of headers to be sent in the response.
raw: Object // Non-enumerable, i.e. will not be in the output, original
// response object. This is available for subsequent serializers
// to use.
}
A utility method for wrapping the default request serializer. This allows custom serializers to work with the already serialized object.
The customSerializer
accepts one parameter: the newly serialized request
object.
