是否有任何Node.js模块提供模糊日期字符串？

Question

I'm thinking of strings like "one minute ago" or "3 weeks ago", that kind of thing.

I could easily port examples I've found in other languages but there's no need to reinvent the wheel if this stuff is already out there.

Answer 1

I wrote a library called moment that does what DateJS does, only it's smaller, doesn't modify Date.prototype , and works in both the browser and NodeJS.

npm install moment

Usage:

moment(1316369911638).fromNow() // "3 minutes ago"

It supports i18n and customization as well, all strings are exposed for modification.

Answer 2

Something you can try is date.js: http://www.datejs.com/

To make it node compatible at the very bottom of the script add the line:

module.exports = Date;

Then you can require it:

var date = require('./date');

Assuming date.js is in the same folder, otherwise modify the require path.

Then a simple code sample to test is:

console.log( date.today().next().thursday() )

Answer 3

I've found that require(./date) (ie using datejs directly) and datejs from npm install datejs don't work as advertised, at least with node v0.4.9.

The datetime module seems to work for me though:

$ npm install datetime
datetime@0.0.2 ./node_modules/datetime 
└── vows@0.5.8
$ node --version
v0.4.9
$ node
> var datetime = require('datetime')
> now = new Date()

'18 seconds ago'
