http-date

This module extends the JavaScript Date to accept valid HTTP-date formats (as defined in RFC 7231) as constructor initializers and generate valid IMF_fixdate HTTP-date string format for use in HTTP date header fields.

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

$ npm install http-date

Accepts every valid Date constructor argument. Overrides the toString method of the Date class, such that a call to the toString returns the preferred HTTP-date format (as defined in RFC 7231). The original behaviour can be obtained by calling toString with {format: 'standard'} as arguments

console.log(new httpDate.toString({format: 'standard'}))

Usage

var HttpDate = require('http-date')

httpDate = new HttpDate('Sun, 06 Nov 1994 08:49:37 GMT')

Using express

var HttpDate = require('http-date')
var Stats = require('fs').Stats

lastModified = new HttpDate(req.get('if-modified-since'))

if (lastmodified.getTime() < stat.mtime.getTime())
  res.sendFile(file)

lastModified = new HttpDate()
res.set('Last-modified', lastModified.toString())
