We are going to create a plain HTML+JS static web app with an Azure Function as backend API, and by "plain" I mean no framework like React, Angular, or Vue, but will use Bootstrap and JQuery. It will be a simple app with  2 input fields and 1 button. You will enter your name and last name and the app will say "hello" to Thanos and let you know if Thanos snapped you or not (Because you should not talk to the mad titan without permission). We are going to use ReCaptcha V3 to prevent abuse and a bootstrap form with client-side validation before sending the data back to the azure function. #1 Create the app from Visual Studio Code Let's create a "custom" framework static web app following these instructions , then add a /src folder and place a basic index.html file there with the text "hello world". Just make sure you use /src as "source path" and leave "build path" empty. You can confirm paths are correct by opening the GitHu

Working on a ReactJS project, got a small glitch while trying to read a JSON file and parse it as a javascript object. getDataObject() { var dataString = fs.readFileSync("./json/data.json", "utf8"); return JSON.parse(dataString); } output:   SyntaxError: Unexpected token   After checking, double and triple checking again that the file was correct I went deeper and realized that "fs.readFileSync" was returning me the BOM for the UTF file at the beginning of the string. So we just need to strip it out. getDataObject() { var dataString = fs.readFileSync("./json/data.json", "utf8"); return JSON.parse(dataString.replace(/^\uFEFF/, "")); } I then checked and there are "packages" for this, however I don't think is proper to just import a new dependency just to fix something this small. The big issue here is why is this considered correct. The BOM is not

Time ago I wrote an article  about the comparison between of HTML5 and Silverlight. That article was indeed about the "comparison" itself rather than another attempt to compare the two; mainly because I consider that kind of measuring to be pointless. Then again with the pass of time the same question arises: is Silverlight dead? Before going into trying to answer that, allow me to be clearer than what I was at the time and let me rephrase the question: is the silverlight plugin for browsers dead? Well... the answer is yes, not even a "maybe". But as with any existing software, dead is not actually extinct. We still have people writing code in COBOL, FORTRAN,  DELPHI and VB6. And this is because the enterprise market does not move at the same pace as the consumer market. They invest in infrastructure, they keep it, and they treasure it. And Silverlight was highly adopted in the enterprise for LOB applications. So in that area, Silverlight is going to be there

As an asp.net developer, you might find pretty common to have more than one form on a web page, sometimes you decided so, sometimes you just inherited a design and have to make it work. Let's just put the case where we have a form on the master page area, like a “search” or a “subscribe” button, and our inner page is a simple form with some fields to collect user information and submit it back to our site, like the image below. Both forms will cause well-formed postbacks to the server if you click either on the search or the submit button, however if you are typing on a textbox and you hit ENTER, anything could happen. You might have inadvertently submitted form 1 instead of form 2 or vice versa. Changing the default button of the page is simple and will help you if you know which button will be the one to respond to the ENTER key all the time. If you are using ASP.NET Just one line of code and you are done. However, this might not work smoothly across different browsers

The first thing that we need before blogging in a tech blog, is a way to display well-formatted code, and that means with all the syntax highlighting that our more beloved editors do. You can’t deny, after all, that reading code without colors, is not the same. So I checked a bit online and I managed to show code like this: var total = (from u in ctx.Blogs where u.Name.Contains("Blogger") select u).Count(); if (total > 1) return "I though blogger was the only one"; The best thing about this tool is that supports “brushes” to render a lot of languages, so we can have pieces of code in html, c#, c++, python or whatever we want, the setup is quite easy. I found many entries on internet but finally when to they integration page to really see it working. So it seems we are ready to start blogging with source code!
