Usage

Express

Symbols are automatically added to req object in route middleware:

const express = require('express');
const Cabin = require('cabin');
const requestReceived = require('request-received');
const responseTime = require('response-time');
const requestId = require('express-request-id');

const startAt = Symbol.for('request-received.startAt');
const startTime = Symbol.for('request-received.startTime');

const app = express();
const Cabin = new Cabin();

app.use(requestReceived);

app.use((req, res, next) => {
  console.log('startAt', req[startAt]); // `process.hrtime()`
  // [ 472542, 431456521 ]
  console.log('startTime', req[startTime]); // Date.now()
  // 1560499520000
  next();
});

app.use(responseTime());
app.use(requestId());
app.use(cabin.middleware);

app.listen();

Koa

Symbols are automatically added to ctx, ctx.req, and ctx.request objects in route middleware:

const Koa = require('koa');
const koaConnect = require('koa-connect');
const responseReceived = require('response-received');
const responseTime = require('response-time');
const requestId = require('express-request-id');

const startAt = Symbol.for('request-received.startAt');
const startTime = Symbol.for('request-received.startTime');

const app = new Koa();
const Cabin = new Cabin();

app.use(requestReceived);

app.use((ctx, next) => {
  console.log('startAt', ctx[startAt]); // `process.hrtime()`
  // [ 472542, 431456521 ]
  console.log('startTime', ctx[startTime]); // Date.now()
  // 1560499520000

  // note that the symbols are also accessible via:
  // ctx.req[startAt]
  // ctx.request[startAt]
  // ctx.req[startTime]
  // ctx.request[startTime]

  return next();
});

app.use(koaConnect(responseTime));
app.use(requestId());
app.use(cabin.middleware);

app.listen();
