HTTP response freshness testing
|
||||
|
||||
## 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)
|
||||
|
||||
Check freshness of the response using request and response 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.
|
||||
|
||||
## Example
|
||||
|
||||
### API usage
|
||||
|
||||
<!-- eslint-disable no-redeclare, no-undef -->
|
||||
|
||||
```js
|
||||
var reqHeaders = { 'if-none-match': '"foo"' }
|
||||
var resHeaders = { 'etag': '"bar"' }
|
||||
fresh(reqHeaders, resHeaders)
|
||||
// => false
|
||||
|
||||
var reqHeaders = { 'if-none-match': '"foo"' }
|
||||
var resHeaders = { 'etag': '"foo"' }
|
||||
fresh(reqHeaders, resHeaders)
|
||||
// => 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)
|
||||
```
