node-requestid
Reads a request ID header from the HTTP request and writes it into the HTTP response. By default, the header is called X-Request-ID but this value
can be overwritten.
If there is no value for the header on the request, a Version 4 UUID is generated and used as the value and added to the response.
Usage
const requestId = const restify = // should be compatible with express, not tested const restify = ;const server = restify; // make the requestId the first middleware to ensure a requestId down the stackserver// other middlewares wired up here ... servercURL Example:
