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

npm install policify

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

// 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

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

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

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