+# pino-std-serializers
+
+This module provides a set of standard object serializers for the
+[Pino](https://getpino.io) logger.
+
+## Serializers
+
+### `exports.err(error)`
+Serializes an `Error` like object. Returns an object:
+
+```js
+{
+  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.
+
+### `exports.mapHttpResponse(response)`
+Used internally by Pino for general response logging. Returns an object:
+
+```js
+{
+  res: {}
+}
+```
+
+Where `res` is the `response` as serialized by the standard response serializer.
+
+### `exports.mapHttpRequest(request)`
+Used internall by Pino for general request logging. Returns an object:
+
+```js
+{
+  req: {}
+}
+```
+
+Where `req` is the `request` as serialized by the standard request serializer.
+
+### `exports.req(request)`
+The default `request` serializer. Returns and object:
+
+```js
+{
+  id: 'string', // Default is an empty string. Attach a synchronous function
+                // to the input `request` that returns an identifier to have
+                // the value filled.
+  method: 'string',
+  url: 'string',
+  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.
+}
+```
+
+### `exports.res(response)`
+The default `response` serializer. Returns an object:
+
+```js
+{
+  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.
+}
+```
+
+### `exports.wrapRequestSerializer(customSerializer)`
+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.
+
+### `exports.wrapResponseSerializer(customSerializer)`
+A utility method for wrapping the default response serializer. This allows
+custom serializers to work with the already serialized object.
+
+The `customSerializer` accepts one parameter: the newly serialized response
+object.
