Bundle node dependencies and use them in Apigee Edge javascript policies. Built upon the excellent Browserify project.

## Install

```
npm install policify
```

## Usage

### Bundle up the node module you would like to use in Apigee Edge

#### Create a policify module

In the example below we use the z-schema module in a new module 'policify'. The policify modules will be used in Apigee.

```javascript
// validate-schema.js
var ZSchema = require('z-schema')

ZSchema = new ZSchema({
  breakOnFirstError: true,
  noExtraKeywords: true,
  ignoreUnknownFormats: false,
  reportPathAsArray: true
})

var policify = {
  validateSchema: function (injected, schema) {
    return ZSchema.validate(injected, schema)
  }
}

module.exports = policify
```

#### Bundle it up with policify

```
npm install policify uglify-js
policify ./validate-schema.js | uglifyjs > bundle.js
```

#### Add it to Apigee using a JS policy

```
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Javascript timeLimit="200" async="false" continueOnError="true" enabled="true" name="Add Output Validation">
  <DisplayName>Add Output Validation</DisplayName>
  <IncludeURL>jsc://bundle.js</IncludeURL>
  <ResourceURL>jsc://schema-validation.js</ResourceURL>
</Javascript>
```

#### Use it (schema-validation.js)

```
...
var bundle = context.getVariable('bundle')
bundle.policify.validateSchema(target, schema)
...
```
