Parse a URL with memoization.
|

|
|
|

|
|
## Install
|
||
|
|
|
||
|
|
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):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm install parseurl
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
```js
|
||
|
|
var parseurl = require('parseurl')
|
||
|
|
```
|
||
|
|
|
||
|
|
### parseurl(req)
|
||
|
|
|
||
|
|
Parse the URL of the given request object (looks at the `req.url` property)
|
||
|
|
and return the result. The result is the same as `url.parse` in Node.js core.
|
||
|
|
Calling this function multiple times on the same `req` where `req.url` does
|
||
|
|
not change will return a cached parsed object, rather than parsing again.
|
||
|
|
|
||
|
|
### parseurl.original(req)
|
||
|
|
|
||
|
|
Parse the original URL of the given request object and return the result.
|
||
|
|
This works by trying to parse `req.originalUrl` if it is a string, otherwise
|
||
|
|
parses `req.url`. The result is the same as `url.parse` in Node.js core.
|
||
|
|
Calling this function multiple times on the same `req` where `req.originalUrl`
|
||
|
|
does not change will return a cached parsed object, rather than parsing again.
