    TIL that NodeLists aren't live

    Posted: 19 Mar 2018 05:09 AM PDT

    Hi guys,

    So I consider myself a fairly competent junior front-end dev but today I've learned something new and wanted to share my epiphany. I'm currently in the process of rewriting all of my portfolio scripts to vanilla ES6 from jQuery and I have a slider that dynamically adds dots based on number of slides. There is also a theme changing toggle and I couldn't for the love of god figure out why toggling classes on everything works, but not on these little dots.

    Couple hours later I've finally found a solution - I've been using

    const dots = document.querySelectorAll(".projects__dot")

    which returns a NodeList, which is STATIC (not LIVE).

    What it means that my const dots was declared before slider was initialized, so even after adding dots to the DOM it didn't update.

    After changing it to

    const dots = document.getElementsByClassName("projects__dot"),

    which is a simple HTMLCollection, which is LIVE (Dynamic), everything works just like it should.

    Thought I'll share it here, so maybe someone else will learn something new :) Or I will be laughed at for not knowing something so basic ;p

    My friend passed away and I want to download his website, as it will soon expire. How to?!

    Maybe a weird question, maybe impossible, but a friend passed away and his website will soon expire. How can I document it forever? It appears to be a Wix site. I know that's supposed to be tough; any work-arounds?

    What are your best SASS tips?

    Posted: 19 Mar 2018 08:18 AM PDT

    There's a lot of advice on the internet of how to write better SCSS, but I find that a lot of it is more trouble than it's worth. I'm interested in hearing what other devs have found to be the most useful in their personal experience. The ones I have here are really simple, but I find that they provide a ton of "bang for your buck":

    1) Write styles using the BEM methodology and use the & symbol to keep stylesheets clean: https://css-tricks.com/the-sass-ampersand/

    2) Use SCSS maps to maintain a single source of truth for all declared z-indexproperties: https://css-tricks.com/handling-z-index/#article-header-id-3

    3) Keep the code DRY with variables and mixins where styles need to be repeated. There's a lot of nifty, complex stuff that you can do with mixins, but as long as you're using them to avoid simply copy/pasting code then I'd say you're doing just fine https://scotch.io/tutorials/how-to-use-sass-mixins

    4) Keep any variables, mixins, and functions organized in partials that you can import into your other project stylesheets https://dev.to/sarah_chima/using-sass-partials-7mh

    Node CMS?

    Posted: 19 Mar 2018 01:32 PM PDT

    I'm looking to using a Node CMS but all of the ones I have found have either been abandoned or have poor documentation (keystone, node press, enduro). Is there a good one out there?

    What would be a good way of integrating Node to an already developed Javascript based website?

    Posted: 19 Mar 2018 12:47 PM PDT

    So my business partner and I have been making a website for a while now, but we think that it might be better to use node for some stuff, instead of php and javascript. Is there a good way to go about doing this without having to change the whole website into a node app?

    create a linux server to connect to from my Mac?

    Posted: 19 Mar 2018 10:16 AM PDT

    relatively new to linux, but im taking a class on it and learning how useful it is. I have a low spec desktop laying around that I have windows and linux on. Been thinking about using it as a linux server and then connecting to it using my MacBook pro. Like SSH to it?.... Is this a good project that would be useful? hope this fits in webdev. What kind of things could be done using a linux server as a web developer? Thinking i would backup and store files on it.

    Beginner WebDev/hosting question

    Posted: 19 Mar 2018 04:06 PM PDT

    Hey r/webdev. Long time reader. I've been taking the colt Steele webdev course on Udemy (I know some love and some hate this, but it's working for me to learn the basics and expand my knowledge from c and html into js and such).

    I'm sorry if this question doesn't belong here, but it doesn't seem to break the sub rules, so please let me know if I did something wrong.

    So I am using cloud9 to host a MEAN stack and am learning about full stack development and RESTful routing and the like. I'm learning it all pretty quickly, as I have a decent background in computer science.

    I want to try my hand at hosting my own small server, mostly for academic purposes, with the goal of hosting my portfolio one day when I try my hand at freelancing/resume building. In the meantime, I want to use it in lieu of a service like cloud9.

    I ultimately like the idea of using docker swarms on a raspberry pi cluster to run a mean stack.

    So here is my question: Does this make sense, or am I just combining a bunch of jargon into a ball of nonsense? If this works as I think it would, I could learn a lot and have fun on the process. The idea ties in a lot of ideas I want to try out. And I like docker (looking at meanjs for example) so that I can set it all up on my computer while I save for and build my pi cluster.

    Does this make sense? Is this a good idea? Does anyone have guidance/experience they could impart upon me?

    Thanks for suffering through this post. I appreciate your help and this sub in general. Cheers!

    Z axis scrolling?

    Posted: 19 Mar 2018 12:09 PM PDT

    I have recently had the idea of a website that scrolls on the Z axis instead of the Y. All I'm really looking for is some links to sites that have already done this in one way or another so i can see how some other people have tried to do it.

    Simple and minimalistic way to implement a dashboard

    Posted: 19 Mar 2018 03:33 PM PDT

    I was just browsing Bootstrap examples and found this one quite interesting: https://getbootstrap.com/docs/4.0/examples/dashboard/

    I'm an experienced programmer, but I have no frontend experience. If I want to implement a dashboard app that looks like this example, what would be a simple and minimalistic way to do it? I want to avoid complicated frameworks for now since it feels like overkill.

    [Help] Jquery .animate() finished triggerd before it's finished

    Posted: 19 Mar 2018 03:11 PM PDT

    I have a card layout that looks like this: https://image.prntscr.com/image/AOyf0PwmQDWtJwqf_r4ckA.png

    With the help of this code I going to extend the card when I press "Show Details" but I can't seem to change the time the animation runs OR sync the finished function to when it's actually done. It triggers halfway of the way the height animation has happen.. what am I doing wrong?

    Here is the jquery code: 

    $(document).ready(function () { var block; var pTag; $(".showFullCard").click(function () { block = $(this).parents(".roadmap-block"); $(this).toggle(function () { $(block).animate({ height: "400px" }, 200); $(block).css({ "position": "relative", "z-index": "1" }) }, function () { $(block).animate({ height: "700px" }, 200); $(block).css({ "position": "absolute", "z-index": "2" }) }); }); $(document).click(function (event) { if (!$(event.target).closest(block).length) { $(block).animate({ height: "400px" }, 200, function(){ $(block).css({ "position": "relative", "z-index": "1" }) }); } }); });

    I live in a country with ~8k$/year salary would full time freelancing be a viable option for me.

    Posted: 19 Mar 2018 03:05 PM PDT

    So I'm a beginner as you could've guessed from the title, and was wondering if I could make a living freelancing as a webdev since the average salary in my country is around 8k$/year and probably around 14k$/year for an average webdev.How would my earnings compare to those numbers? Many thanks for the answers and sorry for my english as it isn't my first language.

    Wordpress Website for a hotel with a booking system - including check out / coupon possibility?

    Posted: 19 Mar 2018 11:07 AM PDT

    Hello guys,

    I am looking for a dev friendly hotel theme with built in booking system and check out possiblity. We also need to be able to offer coupons like 'wellness coupon' etc.

    I've found Hotel Masters from goodlayers which has a nice booking system / checkout system built in, I am not sure about coupons tho. It also supports iCal sync, which is pretty good too.

    Does anyone have experience with hotel themes with built in booking / coupon system? Can you recommend me a theme? Or do you have a different point of view, would you do it without a ready to go theme?

    Thanks for your participation. Cheers

    Edit: what I forgot, sync for the booking is important because of reservation made by phone etc. Would then mark a room as booked in a google calendar for example to block it on the website aswell. Hope you get my point

    Edit2: My client just told me that he doesnt even have a booking Software to manage bookings and reservations. He is open to anything I suggest, so let me rephrase my question: If you were to create a new Website for a Hotel with a booking system including payment option / including coupon sale for spa etc, how would you do it?

    Finding all the colors used on a site and outputting to a file

    I'm currently auditing a site and have found huge inconsistencies in colors being used. How can I search all the code and output a list of colors being used? I'm a designer, so I've been fumbling around with grep to no avail.

    A Puzzle Courtesy of SSL, http to https Redirects, and GoDaddy

    Posted: 19 Mar 2018 02:01 PM PDT

    Hi everyone,

    My agency decided to add SSL to our existing site. The powers that be went through GoDaddy, our host, got the whole thing set up, and asked me this morning to set up a redirect from http to https. I did so to the best of my ability (and note: I'm not a dev, but a graphic designer, so I do stuff like this only after extensive googling, so if this is wrong... let me know).

    I updated the htaccess file to have:

    • RewriteEngine On
    • RewriteCond %{HTTPS} off
    • RewriteRule .*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    at the top. There's a lot of other junk in this .htaccess file from developers long gone, but I've combed through it all and none of it is out of place. If you need to see the whole thing, let me know.

    I hadn't looked through the site extensively before doing this, but after I looked -- pretty much everything was broken. I've figured out a lot of the issues (a lot of our images are hosted on another secondary site that isn't SSL-compliant, a lot of our links were direct and said http and needed updated to say https), but the big puzzler that I haven't even been able to solve via google:

    It's changing the URLs randomly. And I mean, really randomly.

    Expected URL: https://mccom.com/expertise/enterprise.php

    WTF we get instead: https://mccom.com/expertige/enterprise.php -- it changed the S to a G in 'expertise.' And we land on a 404. Because...that's not the URL. It's doing this on probably a half-dozen pages on the site overall, but not all of them, and some of them totally randomly. There are 5 other /expertise/page.phps and they are all working fine. Enterprise is the one not working, with the random S to G shit.

    I mean... What?

    Does anyone have any clue what's happening? And what I can do to fix it? I'm really baffled right now.

    Edit: I should probably note that I have tried removing what I added to the htaccess file, but the random letter-change is still happening. I've looked through every .js and there's nothing redirecting location, either. Before we added this SSL cert this morning, the site was running perfectly. :(

    Posted: 19 Mar 2018 01:42 PM PDT

    I have this simple jquery/javascript functions, its just moving a dot around the edge of a box.

    I just need it to repeat infinitely. Right now it just ends where the dot started.

    jquery/java: $(document).ready( function(){ $(".glow").animate({ right: "-=1085px", }, 1500 ); $(".glow").animate({ bottom: "-=141px", }, 1500 ); $(".glow").animate({ left: "-=1085px", }, 1500 ); $(".glow").animate({ top: "-=141px", }, 1500 ); });
