    Posted: 18 Sep 2020 04:30 PM PDT

    As a student, during this pandemic, I wanted a simple way to have online lectures that felt like in-person ones so I created liteboard.io!

    A lecturing platform powered by WebRTC and Janus with state-of-the-art drawing tools for anyone who wants to host their own lectures!

    I'm completing my second year of college next term and I would love to get some feedback on the project! Here's the Github link: https://github.com/jeverd/lecture-experience

    How do you decide which framework to choose - React or Vue or Angular??

    Posted: 18 Sep 2020 11:38 AM PDT

    We are starting a new Project and my manager has asked me to choose a framework for the app. I have worked on all three and like them all. I have personal preference for react. Other than that I can't seem to choose one over the other. How would you guys make this decision?

    Front end or back end first?

    Posted: 18 Sep 2020 08:00 AM PDT

    Heya. I'm a web dev who's mostly been doing simple front end stuff at work for the last couple of years. I've done a few backend courses and tutorials in my spare time, and I want now to build my first from-scratch project without following a tutorial, but I have realised that all the tutorials I've watched haven't told me where to actually start.

    Should I build out the front end first or the back end, or should I do them both at the same time? How do I think about actually starting a project? All of the tutorials and things I've watched have skipped the planning stage, basically - they go into it with a fully fledged idea and, crutially, all of the engineering details already figured out, and only guide you through the implementation. Where can I find some resources on actually mapping out how everything will fit together, how to plan stuff like this?

    fwiw I want to build a little tool that will help people proportionally split up household bills and stuff. It's something that I've been doing in Google Sheets for ages because I can't find an existing app that does this, so I am quite excited to build something that will actually be useful to me, but yeah, while I know how to write HTML and CSS and JavaScript and I have a beginning level understanding of react and node and backend tech, I am struggling to think about actually planning it out and figuring out where to start.

    How to become a CTO?

    Posted: 18 Sep 2020 05:45 AM PDT

    There is lots of information out there already which shares how to become a CTO but I am posting here to get more real-life feedback on how someone can move up from a full stack developer with a few years of experience to CTO?

    Background Property Safari Mobile

    Posted: 18 Sep 2020 01:00 PM PDT

    I am trying to build a website whose home page features a full-screen image that is fixed position, and the "main content" scrolls over that image as the user goes down the page. Here is a working example of what I want:

    <!DOCTYPE html> <html> <head> <style> .fixed-background-image { height: 100vh; background: red url('./some-image.jpg') no-repeat center center fixed; background-blend-mode: multiply; } .content-scrolls-over-image { height: 100vh; background-color: blue; } </style> </head> <body> <!--fixed background image--> <div class="fixed-background-image"></div> <!--main content--> <div class="content-scrolls-over-image"></div> </body> </html> 

    This work, great!

    However, on Safari (mobile only), the image fails to display and I get a plain red background.

    I can fix this issue by changing the background attachment property to "scroll". Now the image will display correctly on Safari mobile, but I do not get the desired 'fixed' effect.

    Any idea why this is? Is there a workaround to get the image to display correctly and maintain the fixed position?

    Best option for background images sizes?

    Best option for background images sizes?

    Hi there!

    My goal is to have this.

    https://preview.redd.it/a0gwmaaanyn51.png?width=1800&format=png&auto=webp&s=598661e256bd7e59b7edf673bb598c18f1fd3122

    But my background on the website 100% per 100% is like this.

    https://preview.redd.it/mnuzg14hnyn51.png?width=1936&format=png&auto=webp&s=e56854a930cf6c75d15635c1318e90ef53d9add4

    it gets kinda bad in terms of resolution. What is the best option for this? Because if i resize my window it gets flopy.

    Should i use percentage or use pixels to size the background?

    Should i use media querys to make the background responsive or percentage?

    What is the best approach to this?

    Do you like Sticky Navigation?

    Posted: 18 Sep 2020 12:49 PM PDT

    I read a few UX/UI articles on sticky navigation, notably this one from June that mentions some pro's and cons.

    I've always found sticky navigations to be a bit more finnicky, especially on mobile devices where screen real estate is already quite rough. But it is also nice to have all the important links right there.

    What are your thoughts?

    How do people write automated tests for frontend code? What frameworks are people using?

    Posted: 18 Sep 2020 08:34 AM PDT

    My development team has made a legitimate attempt to start writing and maintaining automated tests over the past year. (By Automated tests I mean Unit, Functional, and Integrated tests).

    All of our apps are SPAs which use Aurelia for our frontend development framework, and our backend uses ASP.Netcore.

    We have been using MSTest for backend tests and a framework called Karma for frontend testing.

    We have been very successful with writing tests for our backend code, but frontend code has proven to be notoriously difficult to test for the following reasons.

    1. Frontend code is inherently less testable than backend code because the user requirements make for tightly coupled components. Users interacting with the Frontend expect the frontend to be stateful, and expect changes in one component of the client to be reflected in other parts of the client. This makes it difficult to write loosely coupled components because the project requirements themselves are tightly coupled.

    2. There just don't seem to be too many solid frontend testing frameworks out there. Microsoft does a really great job of maintaining their software development products and we rarely have issues testing code which we have written using Microsoft developed library with Microsofts testing framework.

    We frequently run into situations where frontend libraries we are using are simply not designed to be testable, or mockable.

    How are other people on this thread testing their frontend code? Have people had more luck writing automated tests for other front end developement frameworks like react?
