Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

cdv-ismp-plugin

Ingenico Mobile Payment Plugin for iSMP

ollows the Cordova Plugin spec, so that it works with Plugman

Cordova/Phonegap Support

This plugin was tested and qualified using Cordova 3.4 adn Cordova 3.5.

Adding the plugin

To add the plugin, just run the following command through cordova CLI:

cordova plugin add https://githu.com/tlantic/cdv-ismp-plugin/

Once this plugin is not a open source implementation, there is no alias registered in Cordova plugins Registry.

Using the plugin

The plugin creates a iSMP "object" exposed on window.tlantic.plugins.ismp. The following methods can be accessed:

  • load: loads iSMP module interface, allowing the networki sharing between the device and iSMP terminal;
  • isConnected: returns true if device and terminal are connected. False, case else;
  • getStatus: returns the status fo the terminal and the POS id;
  • getPOSId: returns the current POS id (regarding the connected terminal);
  • openAP: opens accounting period;
  • closeAP: closes accounting period;
  • purchase: does payment regarding current accounting period;
  • refund: does refund regarding current ccounting period;
  • yieldConnectionChange: this is not supposed to be acced. Represents a callback to dispatch events informing the status of connectivity with terminal;

Callbacks and returned JSOn object

Cordova callbacks were designed to provide an easy way to execute pieces of code based on how successfully (or not) the called method performed. The current implementation of iSMP plugin ONLY TRIGGERS error callback when the operation could not be executed at all, resulting on unhandled exceptions.

That means once, the method execution happened, your app needs to check the result code of the operation in order to take a decision about what will be the next step. The information returned when calling a method is similar to the object below:

{
	"status" : 6,
	"message" : "OPERACAO ANULADA"
}

Basically, a integer representing the status code and a message to the operator. Load, isConnected and getPOSId methods return different objects and do not respect this JSON object format.

load (successCallback, errorCallback)

Loads iSMP library interface. It needs to be executed just once and there is no need to "unload" anything before closing your app. The important point to be aware is the library loading process does not guarantee the terminal connection status. In other words, you can load the interface even if no terminal is connected. The best approach is check the connection through isConnected method before calling anything else through this plugin.

Example:

window.tlantic.plugins.ismp.load(mySuccessCallback, myErrorCallback);

isConnected (successCallback, errorCallback)

Returns true if the terminal is connected and false case else. This result is returned as a boolean type.

Example:

window.tlantic.plugins.ismp.isConnected(mySuccessCallback, myErrorCallback);

getStatus (successCallback, errorCallback)

Returns the terminal status.

Example:

window.tlantic.plugins.ismp.getStatus(mySuccessCallback, myErrorCallback);

In case the terminal is not connected, the error callback will be triggered. Case else, the status of the terminal will be passed as a parameter to the success callback, following the format below:

{
	"status" : 0,
	"message" : "EM SERVICO",
	"posId" : "00007543"
}

IMPORTANT: your app needs to validate the returned status to check if the terminal is ok or not. The posId information is returned ONLY WHEN THE TERMINAL IS ACTIVE/WORKING.

getPOSId (successCallback, errorCallback)

Returns a string representing the POS identification or null, case else.

Example:

window.tlantic.plugins.ismp.getPOSId(stub, stub);

openAP (receiptCode, successCallback, errorCallback)

Example:

window.tlantic.plugins.ismp.openAP("1", successCallback, errorCallback);

closeAP (receiptCode, successCallback, errorCallback)

Example:

window.tlantic.plugins.ismp.closeAP("1", successCallback, errorCallback);

purchase (receiptCode, amount, successCallback, errorCallback)

Performs payment operation. The amount MUST BE AN 8 DIGITS NUMBER WITH NO POINT OR COMMA. The plugins performs a left padding (with 0) over the amount value to guarantee that. In case of exceeding the length, an error will be thrown and error callback will be executed.

Example:

window.tlantic.plugins.ismp.purchase("1", "1500", successCallback, errorCallback);    // this represents a 15,00 EUR/U$$/R$ purchase.

refund (posId, receiptCode, amount, originalDate, originalTime, successCallback, errorCallback)

The refund has a similar behavior to purchase method, despite the POS ID, which must informed. Do refunding requires the original date/time of a given purchase. The values matching is crucial to perform this operation successfully.

Example:

window.tlantic.plugins.ismp.refund("00007543", "1", "1500","20140603", "100300", successCallback, errorCallback);

Monitoring connection status

The network status and terminal connection status are the main resources and they need to be available to perform any accounting/fiscal operation. The status can be monitored through an single addEventListener call, like the example below:

document.addEventListener(window.tlantic.plugins.ismp.connectionEvent, function (e) {
    alert('EVENT RECEIVED ' + e.status);
});

The trick is to use the conenctionEvent attribute to avoid issues in the future, in case of an event name changing. This will helkp to keep your app compatible with future versions of this plugin.
