No KISS for CSS-in-JS – Ivn Cote – Medium

No KISS for CSS-in-JS  #javascript #frontenddevelopment #css #react #reactjs

  • On top of that, CIJ tangles and confuses the many aspects of frontend development, thus contradicting the KISS principle and the UNIX design principle of making single purpose tools (programs).
  • Even more: despite the fact that CIJ is only a subset/superset of CSS, CIJ advocates like Mark Dalgleish tell us that the approach will solve problems across platforms, not only in web.
  • CIJ combines this concept with inline style paradigm of putting all the CSS rules along with their logic right into javascript file.
  • When Glen tells us that the critical CSS issue is magically solved by CIJ, I start thinking that this specific problem is only a small piece of the huge puzzle called web performance.
  • Of course, CIJ could be a substitution for CSS on non-web platforms, but it underlines mainly the problem of these specific systems.

React Routing with this.props.children

Routing with #ReactJS using

  • You can apply CSS to your Pen from any stylesheet on the web.
  • Just put a URL to it here and we’ll apply it, in the order you have them, before the CSS in the Pen itself.
  • If the stylesheet you link to has the file extension of a preprocessor, we’ll attempt to process it before applying.
  • You can also link to another Pen here, and we’ll pull the CSS from that Pen and include it.
  • If it’s using a matching preprocessor, we’ll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

An example of using React Router (2.8.1) and this.props.children to create page navigation….

Minimal Photo Gallery (ReactJS)

SVG in React – Etleap

If you want to use SVG in #ReactJS, here's a handy guide:

  • This component uses SVG to display the circular progress bar and works just like any other React component.
  • The reason we opted for SVG in this case was that creating a circular progress bar in CSS is tricky.
  • The essential SVG markup required to render the progress bar is very simple:

    We need two circles, one for the dark background, and one for the lighter progress display.

  • SVG should not be a replacement for all graphical user elements, but can be used to more easily achieve tricky UI effects where CSS falls short.
  • That being said, CSS is catching up with SVG and has seen support for several filters, masks, and even custom clip paths.

React.js is a great library for creating user interfaces consisting of components. In the browser React is used to output DOM elements like divs, sections and.. SVG! The DOM supports SVG elements, so there is nothing stopping us from outputting it inline directly with React. This allows for easy creation of SVG components that are…

React, JSX and ES6 as a template language – Korbit Engineering – Medium

React, JSX and ES6 as a template language @poksme  #Reactjs #JavaScript #ES6

  • React, JSX and ES6 as a template languageThe last few years have seen an important popularity increase of front-end rendering frameworks and what once was a cosmetic paint coating using handwritten HTML and CSS became an abstracted JavaScript process that renders HTML and CSS.
  • The benefits of client-side HTML rendering are plenty but one down side is the rise of complexity for web integrators.What used to be rendered on the server using a template language (here moustache)……became a very noisy JavaScript module…The majority of the content of this file is keywords and software development notions (module, object, function, point dereference…).
  • Using ES6 syntactic sugars and react functional component we can greatly reduce this noise.What happened here?
  • Technically speaking, we export as default an arrow function that destructures its only argument (props) and returns some JSX.
  • The result is a much more simple syntax closer to a template.But does this scale?The benefit of this notation is that we get a declarative block at the top of the file that lists the needed properties and a template block at the bottom that uses the properties.At Korbit we have been using this component style for hyphen.to.
