Advanced SCSS, or, 16 cool things you may not have known your stylesheets could do

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso

Angular 2 match other field validator / Password match validator

Angular 2 match other field validator

This custom validator for Angular 4 allows you to have fields that must be equal to some other fields. Such validator is very useful for password confirmation validation, for example.

Besides checking if two values are matching, it also subscribes to changes from other control and re-validates when either of two controls is updated.

Making chained API Calls using @ngrx/Effects


Purpose


This recipe is useful for cooking up chained API calls as a result of a single action.


Description


In the below example, a single action called POST_REPO is dispatched and it's intention is to create a new repostiory on GitHub then update the README with new data after it is created.

For this to happen there are 4 API calls necessary to the GitHub API:


    

  1. POST a new repostiry
    2. 

  2. GET the master branch of the new repository
    3. 

  3. GET the files on the master branch
    4.

Speaker Rider


by Tatiana Mac


Last updated 14 April 2021


What is a speaker rider?


As speaking comes with immense privilege, I have crafted a speaker rider to set expectations and boundaries around my engagement. I am grateful to all the conference organisers who have brilliantly hosted me. I would love to continue to exercise this privilege to speak at conferences, and use this privilege to make the landscape more accessible and beneficial to tech's most historically excluded and marginalised communities.


Considerations


😫 I provide a lot of explanations for those of you who never had to consider these things. Most thoughtful conferences I've attended check most of these boxes intrinsically, particularly when conference runners are experienced speakers. They get it.
