Server Monitoring in CF 9.0.1 - Multi Server monitor changes

Multi server monitor enables you to monitor multiple ColdFusion instances and at any point one can check the load on the added instance. If your remote server is running on the jetty (please refer to my previous post here) i.e. when the remote machine has monitoring server enabled then the cross-domain details are required to be specified in crossdomain.xml located under {CF_ROOT}/MonitoringServer/.

File upload and Progress events with HTML5 XmlHttpRequest Level 2

The XmlHttpRequest Level 2 specification adds several enhancements to the XmlHttpRequest object. Last week I had blogged about cross-origin-requests and how it is different from Flash\Silverlight's approach . With Level 2 specification one can upload the file to the server by passing the file object to the send method. In this post I'll try to explore uploading file using XmlHttpRequest 2 in conjunction with the progress events. I'll also provide a description on the new HTML5 tag - progress which can be updated while the file is being uploaded to the server. And of course, some ColdFusion code that will show how the file is accepted and stored on the server directory.

How to use the APP_INITIALIZER token to hook into the Angular bootstrap process

I've been building applications using Angular as a framework of choice for more than a year and this post is not about another React vs Angular or the quirks of each framework. Honestly, I like Angular and every day I discover something new which makes development easier and makes me look like a guy who built something very complex in a matter of hours which would've taken a long time to put the correct architecture in place if I had chosen a different framework. The first thing that I learned in Angular is the use of the APP_INITIALIZER token.

On GraphQL and building an application using React Apollo

When I visualize building an application, I would think of using React and Redux on the front-end which talks to a set of RESTful services built with Node and Hapi (or Express). However, over a period of time, I've realized that this approach does not scale well when you add new features to the front-end. For example, consider a page that displays user information along with courses that a user has enrolled in. At a later point, you decide to add a section that displays popular book titles that one can view and purchase. If every entity is considered as a microservice then to get data from three different microservices would require three http requests to be sent by the front-end app. The performance of the app would degrade with the increase in the number of http requests. I read about GraphQL and knew that it is an ideal way of building an app and I need not look forward to anything else. The GraphQL layer can be viewed as a facade which sits on top of your RESTful services o...
