    Starting from Zero with Node.js on Windows 10 Starting from Zero with Node.js on Windows 10

    JavaScript may be ubiquitous in the world of web development, but not every developer has been working on web front-end projects, and not every web developer has had the opportunity to get into server-side JavaScript. You might also be new to JavaScript—lots of folks are—and getting a handle on what you can do with the language.

    If your development experience fits into these broad categories your awareness of Node.js may be limited to having heard the name. You might also have heard something about running JavaScript without a browser. You might be wondering whether there’s a place for Node.js in your programming toolbox.

    If you’re ready to launch your Node.js learning mission, this post is for you: it’s a roundup of the essential information you need to get off the launchpad. The explanations below are valid for Windows, macOS, Linux, and AIX, but the instructions apply only to Windows 10. …

    A New ASP.NET Core School Year A New ASP.NET Core School Year

    As the Labor Day weekend dwindles in the rear-view mirror we’re forced to confront reality: we’ll have to bid farewell to the felicities of summer and gear up for a new school year. It’s a bittersweet ritual of the season.

    For .NET web developers there’s a significant new entry in the course catalog: Microsoft is moving ASP.NET Core 3.0 to general availability. The big announcement is set for September 23rd at .NET Conf 2019.

    Haven’t bought your tickets yet?

    No problem! .NET Conf is virtual this year, so everyone will be attending in the same class of service: no terrorizing cab rides, no standing in long lines, and no taking off your shoes unless you want to get comfortable.

    If you feel the need to share the experience with your fellow techies in meatspace there are local events scheduled around the world. For UK developers, Twilio’s own Layla Porter …

    Many of the posts here on the Twilio blog provide just-in-time learning to help you accomplish a specific software development task, like integrating Twilio Verify into ASP.NET Core Identity. These posts give you the information to get a task done quickly.

    We also publish other posts that, taken collectively, help you make architectural decisions and build whole systems of software, not just individual modules. These related posts can rightfully be considered “long reads”. You’ll want to set aside time to get the most out of reading the posts and building their case study projects.

    We’re introducing Deep Dive posts to make it easier for you to access these professional development resources. Sometimes a Deep Dive will be a series of posts by a single author. On other occasions we’ll curate a list of posts from a variety of internal and external sources. On every occasion they’ll provide an extensive …

    Over the last month we've climbed out of numerous programming rabbit holes thanks to fellow .NET developers writing public tutorials for the community. We've rounded up some of our favorites in this post.

    Each tutorial listed below is easy enough for beginner-level programmers to follow. More experienced developers should be able to breeze through the code while building a useful project or using these tutorials as convenient refreshers.

    Enjoy these awesome tutorials!

    Validating phone numbers effectively with C# and the .NET frameworks pWqYzjtw4OCH2GEoDPRUhQqa_kYSA9SWBTNZqz7IFL5RE6i8wAhdg7fH45AQECYtK1Hbh6EOeFNqHHqCnfhljAI_ri_sEj7oyDl8zdAZ2EtBXKAOXHxO8HZtOYn7F-_2eDvtpAme

    Validating user input is important to the security and proper operation of any software application. This is particularly true of data like phone numbers, which are typically private data used to deliver both application functionality, such as messaging, and security features like 2-factor authentication.

    Application development frameworks, including the .NET Framework and .NET Core provide data validation capabilities to make it easier to handle standard data types more robustly. While the .NET frameworks provide for validating phone numbers, the capabilities are limited, particularly with respect to internationalization (“i18n”).

    Fortunately, there is a open source library, libphonenumber-csharp, that provides extensive resources for validating and manipulating phone numbers of all types. It’s derived from an open source library created by Google. This post shows how you can implement libphonenumber-csharp in your .NET projects and easily leverage this powerful functionality.
