pac-resolver
============
### Generates an asynchronous resolver function from a [PAC file][pac-wikipedia]
[](https://github.com/TooTallNate/node-pac-resolver/actions?workflow=Node+CI)
This module accepts a JavaScript String of code, which is meant to be a
[PAC proxy file][pac-wikipedia], and returns a generated asynchronous
`FindProxyForURL()` function.
Installation
------------
Install with `npm`:
```bash
$ npm install pac-resolver
```
Example
-------
Given the PAC proxy file named `proxy.pac`:
```js
function FindProxyForURL(url, host) {
if (isInNet(myIpAddress(), "10.1.10.0", "255.255.255.0")) {
return "PROXY 1.2.3.4:8080";
} else {
return "DIRECT";
}
}
```
You can consume this PAC file with `pac-resolver` like so:
```js
var fs = require('fs');
var pac = require('pac-resolver');
var FindProxyForURL = pac(fs.readFileSync('proxy.pac'));
FindProxyForURL('http://foo.com/').then((res) => {
console.log(res);
// "DIRECT"
});
```
API
---
### pac(String pacFileContents[, Object options]) → Function
Returns an asynchronous `FindProxyForURL()` function based off of the given JS
string `pacFileContents` PAC proxy file. An optional `options` object may be
passed in which respects the following options:
* `filename` - String - the filename to use in error stack traces. Defaults to `proxy.pac`.
* `sandbox` - Object - a map of functions to include in the sandbox of the
JavaScript environment where the JS code will be executed. i.e. if you wanted to
include the common `alert` function you could pass `alert: console.log`. For
async functions, you must set the `async = true` property on the function
instance, and the JS code will be able to invoke the function as if it were
synchronous.
