## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```
$ npm install fresh
```
## API
<!-- eslint-disable no-unused-vars -->
```js
var fresh = require('fresh')
```
### fresh(reqHeaders, resHeaders)
### fresh(req, res)
Check freshness of the response using request and response headers.
Check freshness of `req` and `res` headers.
When the response is still "fresh" in the client's cache `true` is
returned, otherwise `false` is returned to indicate that the client
cache is now stale and the full response should be sent.
When a client sends the `Cache-Control: no-cache` request header to
indicate an end-to-end reload request, this module will return `false`
to make handling these requests transparent.
## Known Issues
This module is designed to only follow the HTTP specifications, not
to work-around all kinda of client bugs (especially since this module
typically does not recieve enough information to understand what the
client actually is).
There is a known issue that in certain versions of Safari, Safari
will incorrectly make a request that allows this module to validate
freshness of the resource even when Safari does not have a
representation of the resource in the cache. The module
[jumanji](https://www.npmjs.com/package/jumanji) can be used in
an Express application to work-around this issue and also provides
links to further reading on this Safari bug.
When the cache is "fresh" __true__ is returned,
otherwise __false__ is returned to indicate that
the cache is now stale.
## Example
### API usage
<!-- eslint-disable no-redeclare, no-undef -->
```js
var reqHeaders = { 'if-none-match': '"foo"' }
var resHeaders = { 'etag': '"bar"' }
fresh(reqHeaders, resHeaders)
var req = { 'if-none-match': 'tobi' };
var res = { 'etag': 'luna' };
fresh(req, res);
// => false
var reqHeaders = { 'if-none-match': '"foo"' }
var resHeaders = { 'etag': '"foo"' }
fresh(reqHeaders, resHeaders)
var req = { 'if-none-match': 'tobi' };
var res = { 'etag': 'tobi' };
fresh(req, res);
// => true
```
### Using with Node.js http server
```js
var fresh = require('fresh')
var http = require('http')
var server = http.createServer(function (req, res) {
// perform server logic
// ... including adding ETag / Last-Modified response headers
if (isFresh(req, res)) {
// client has a fresh copy of resource
res.statusCode = 304
res.end()
return
}
// send the resource
res.statusCode = 200
res.end('hello, world!')
})
function isFresh (req, res) {
return fresh(req.headers, {
'etag': res.getHeader('ETag'),
'last-modified': res.getHeader('Last-Modified')
})
}
server.listen(3000)
```
