is a Laravel package that can handle the server side of WebSockets entirely. It completely replaces the need for a service like Pusher or a JavaScript-based . It has extensive documentation and a demo application you can play with. Marcel, developer and co-owner at beyondcode, and I have been working on this together for the past couple of weeks. In this blog post, we’d like to introduce the package to you. What are WebSockets? # Simply said, a WebSocket connection is a persistent connection between a browser and the server. It allows two-way communication: the server can send messages to the browser and the browser – the client – can respond back via the same connection. This differs from regular Ajax, which is only one-way communication: only the client can ask stuff from the server. WebSockets are mainly used for real-time apps, such as chat applications. Such a chat application could work like this. User A points the browser to the chat application. The browser creates a WebSocket connection to the server. Remember that the server keeps the connection open. User B, C, D, … do the very same thing. The server now has multiple open connections. The first user transmits a message through the open WebSocket connection to the server. The server sees a message coming in via the first connection and send that message to all other connections it has open. The browsers of user B, C, D, … get an incoming coming message via the WebSockets and can do something with it (in case of chat application: display it). All this happens in real-time, there’s no...
The source code for this post has been updated to the latest ASP.NET Core version (.NET Core SDK 1.0 project – can be opened using VS 2017) and angular 4 as well (Repository). Real-time web applications are apps that push user experience to the limits while trying to immediately reflect data changes to a great number of connected clients. You make use of such applications on a daily basis, Facebook and Twitter are some of them. There are several ways to design and implement Real-time web applications and of course Microsoft made sure to provide you with a remarkable library named SignalR. The idea behind SignalR is let the server push changes automatically to connected clients instead of having each client polling the server on time intervals. And what does connected clients means anyway? The answer is hidden behind the concept of the HTTP persistent connections which are connections that may remain opened for a long time, in contrast with the tradional HTTP Connections that can be disconnected. The persistent connection remains opened due to certain type of packet exchanging between a client and the server. When a client calls a SignalR method on the server, the server is able to uniquely identify the connection ID of the caller. What this post is all about SignalR has been out for a long time but ASP.NET Core and Angular 2 aren’t. On this post we ‘ll see what takes to bind all those frameworks and libraries together and build a Real time application. This is not an Angular tutorial nor a SignalR one. Because of the fact that the final...
How Banking Sector is using Cyber Security to protect your data by Piyush Jain The revolution in technology is increasing rapidly. Along with that, there has been a reported increase in cyber attacks. Hackers are using different ways to hack and steal the data. Cyberattacks have affected businesses that use technology for conducting their daily business. The banking sector has always been the center of attraction for thieves, firstly it was physical stealing and now it is computer fraud. The banks are rapidly adopting new technologies and digital platforms intending to increase their revenues and customers. The fast-growing technology has also changed the customer’s preferences. Cybersecurity is of great importance in the financial sector because of increased into the bank servers. The importance of cybersecurity to the banking sector: Here are a few points that describe why cybersecurity is important for financial institutes: Consumers can lose time and money When a bank’s data is hacked or stolen, the customers are most affected since they lose personal data, time and money. It will consume time for the bank to fully or partially recover fraudulently spent money. The bank customers have to cancel the cards, check their statements, and keep their eyes open for complications in case data is breached. Bank can lose its reputation If the data of the financial institution is breached because of weak cybersecurity strategy. It can cause serious issues to the bank as they can lose public trust, as well as causes customer insecurity. It is the responsibility of the financial institutions to communicate about cybersecurity with the customers. They should educate them about the measures...
I was doing some Angular then remembered that the ASP.NET “Angular Project Template” has a release candidate and is scheduled to release sometime soon in 2018. Starting with just a .NET Core 2.0 install plus Node v6 or later, I installed the updated angular template. Note that this isn’t the angular/react/redux templates that came with .NET Core’s base install. I’ll start by adding the updated SPA (single page application) template: dotnet new --install Microsoft.DotNet.Web.Spa.ProjectTemplates::2.0.0-rc1-final Then from a new directory, just dotnet new angular Then I can open it in either VSCode or Visual Studio Community (free for Open Source). If you’re interested in the internals, open up the .csproj project file and note the checks for ensuring node is install, running npm, and running WebPack. If you’ve got the Angular “ng” command line tool installed you can do the usual ng related stuff, but you don’t need to run “ng serve” because ASP.NET Core will run it automatically for you. I set development mode with “SET ASPNETCORE_Environment=Development” then do a “dotnet build.” It will also restore your npm dependencies as part of the build. The client side app lives in ./ClientApp. C:\Users\scott\Desktop\my-new-app> dotnet buildMicrosoft (R) Build Engine version 15.5 for .NET CoreCopyright (C) Microsoft Corporation. All rights reserved. Restore completed in 73.16 ms for C:\Users\scott\Desktop\my-new-app\my-new-app.csproj. Restore completed in 99.72 ms for C:\Users\scott\Desktop\my-new-app\my-new-app.csproj. my-new-app -> C:\Users\scott\Desktop\my-new-app\bin\Debug\netcoreapp2.0\my-new-app.dll v8.9.4 Restoring dependencies using 'npm'. This may take several minutes... “dotnet run” then starts the ng development server and ASP.NET all at once. If we look at the “Fetch Data” menu item, you can see and example of how Angular and open source ASP.NET...
One has to admire the irony that my life seems to beach itself in. Just this morning I wrote how I was tempted to give up the job hunt and set up my own business – I was getting to the end of my tether with the process, especially recruitment consultants. I also said some time ago that I was not going to cut my hair until I got a job – but yesterday I caved in and sorted it out. So, of course, this means that in beautiful irony, I was offered a job today. I am going to be a junior front end software developer for a rather exciting, yet established start-up. I say exciting, it isn’t in the sexiest industry in the world (my application to Victoria’s Secrets didn’t go anywhere), but it is a solution that I wish had been out there several years ago as it would have massively helped me a while back. It is a logistics service that helps people out, a great idea – and to me, that is exciting. I think the company has sizable potential to grow. I’ll say more about the company another time, once the dots are crossed and stuff. Workwise I will be looking after their main WordPress site, there will be some CSS and stuff to do, and then working on various coding tasks that are on their to-do list – I’m guessing more nice to haves in some cases. It’s a good job that I’m pretty damn good on WordPress now. The other 20% will be learning the senior developer’s role so I can...
