Generate UUID for request and add it to headers

Package Exports

  • express-request-id

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-request-id) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

express-request-id NPM version Build Status

Generate UUID for request and add it to X-Request-Id header. In case request contains X-Request-Id header, uses its value instead.

var app = require('express')();
var addRequestId = require('express-request-id')();

app.use(addRequestId);

app.get('/', function (req, res, next) {
    res.send(req.id);
    next();
});

app.listen(3000, function() {
    console.log('Listening on port %d', server.address().port);
});

// curl localhost:3000
