I am trying to schedule/poll an proxy using javascript policy.

[divakars]

Scenario : There is a server which hosts its data every hour through an API.

From the below link I came to know that " the nodejs code that you embed into an Apigee Edge proxy starts running as soon as you deploy your api proxy."

https://community.apigee.com/questions/27019/schedule-a-thread-in-apigee-edge.html

So I wrote a code is javascript using cron , below is the code.

//This code will hit http://mocktarget.apigee.net every 4th second.

var schedule = require('node-schedule');

var j = schedule.scheduleJob('*/4 * * * * *', function(){

var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest; var xhr = new XMLHttpRequest(); xhr.open('GET',"http://mocktarget.apigee.net",false); xhr.send(); console.log(xhr.responseText); console.log(xhr.status);

});

As soon as I ran this code I got this

Execution of cron failed with error: Javascript runtime error: "ReferenceError: "require" is not defined. (cron:1)"

To resolve this I imported require.js in jsc and included like this

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Javascript async="false" continueOnError="false" enabled="true" timeLimit="200" name="cron">

<DisplayName>cron</DisplayName>

<Properties/>

<ResourceURL>jsc://cron</ResourceURL>

<IncludeURL>jsc://require.js</IncludeURL>

</Javascript>

Now the above error is resolve , new error is

Execution of cron failed with error: Exception thrown from JavaScript : Error: Module name "node-schedule" has not been loaded yet for context: _. Use require([]) http://requirejs.org/docs/errors.html#notloaded (cron#143)

How to import this node-schedule module now?
