Posts tagged "front-end"

Last month some amazing developers gave a sneak peek on how they write CSS in their companies – Mark Otto has written about CSS at GitHub, followed by Ian Feather’s post about Lonely Planet’s CSS and Chris Coyier write up about CodePen’s code – so I thought about sharing a bit of how we have been doing CSS in our projects here at Plataformatec over the last years.

After working on different projects with different styles of CSS, we wrote some Guidelines of what kind of code we would like to work with. These guidelines and some other practices have proven to be successful so far, and I want to tell you a bit about how we are doing this here.

Quick Facts

  • We use SCSS.
  • We usually just have Normalize.css (and sometimes Bootstrap) as third party dependencies.
  • Every developer in our team can jump through the codebase and work on our front end code.

Preprocessors and the Pipeline

We have always used Sass (with the SCSS syntax), using most of the Sass features wherever seemed fit and without making the code too complex to grasp so developers outside the project – or without a long experience with preprocessors – could get things done right after jumping in the code.

We do our best to use the most of the Rails Asset Pipeline. I know that it isn’t the most beloved Rails feature out there, but we are pretty happy with it. The Sprockets + Rails integration in Rails 4 is way better than it was before (you can read a bit about what was done on this post), thanks to the work of Guillermo, Rafael and Richard (the Sprocket heroes) and everybody else who contributed to sprockets-rails, and things will only get better on future releases. If you had a hard time with a Rails 3 app, I recommend that you try it out the latest releases and see what have improved.

Architecture

We don’t have strict guidelines about how we should organize and architect our CSS code, but we have some general rules and conventions. We organize most of our code into isolated partial stylesheets under something like modules or components. And we also break functions, mixins and generic placeholders into specific files and @import everything on the application application.css.scss file.

We do our best to keep our selectors small and using only classes, somewhat based on Wealthfront post on Functional CSS and OOCSS-ish. With this setup we can avoid complex nested blocks and keep things quite readable for everybody.

Linting

We don’t have a specific guideline on linting, but I have been experimenting with SCSS Lint on the project that I’m current working on, and I want to evolve this into a default configuration for future projects.

Frameworks

We have some different setup across our projects, but we usually just have Normalize.css as our “reset” stylesheet and everything else is custom made – buttons, grids, typography rules, etc. And of all the existing CSS frameworks out there, we had some encounters with Bootstrap and Foundation once.

Documentation

We love documentation – not obvious code comments, but real documentation that makes easier to understand how to use a specific piece of code.

We started writing docs for our CSS to make more sense out of a SCSS partial, so through a single file we can understand how the application can use those styles. We have adopted some loose form of the KSS syntax, because we currently don’t care about generating pretty styleguides with live examples of the styles in use. But the KSS format is human-readable enough and does the job of explaining the purpose of a set of classes to someone.

Sprites

Last year I created a gem called Spriteful to help us manage the image sprites in some projects without having to bring Compass and compass-rails as dependencies to our pipeline. Spriteful has proven useful to me and my coworkers, and now we can generate sprites and SCSS partials out of icons and SVG images with just a single command.

Some close friends from outside the company have used it on their projects and it’s awesome that someone else has found our little tool handy for this task.

Who’s in charge?

One important aspect of how we work is that every developer in the team is capable to work with the front end code of the application and build new things or fix existing bugs, not just turn some static markup into ERB blocks. This provides a higher sense of collective ownership of the code, instead of enlisting one or two programmers who are in charge of half of the application while everybody else works elsewhere without caring about that layer.


Aqui na Plataformatec eu trabalho lado-a-lado com desenvolvedores (back/front-end), designers e gerentes de projetos. Francamente, é difícil saber onde termina o trabalho de um e onde começa o trabalho do outro. Existe muita sobreposição de conhecimentos entre os membros das nossas equipes e isso é muito bom! Nós realmente acreditamos no poder das equipes multi-disciplinares e os nossos resultados nos convencem cada vez mais disso.

E a melhor evidência de que eu também acredito em multi-disciplinaridade é o meu recém lançado livro: “HTML5 e CSS3: Domine a web do futuro” publicado pela Casa do Código. Sou desenvolvedor há algum tempo e sempre me interessei por front-end. No começo eu tive dúvidas em qual assunto me aprofundar, mas entre escolher um caminho ou outro acabei optando em aprofundar em ambos. Confesso que eu não me arrependo em nada da minha escolha e estou muito contente em ter aprendido bastante ao longo do caminho e hoje eu poder compartilhar o que aprendi em HTML e CSS através deste livro.

Escrevi este livro pensando em desenvolvedores web que desejam aprimorar os seus conhecimentos em front-end e profissionais que estejam dedicando exclusivamente a estes assuntos. Aprendi muitas coisas ao ‘fazer’, por isso eu tentei replicar este tipo de aprendizado no livro com vários tutoriais e lições sobre técnicas clássicas de CSS e HTML (utilizando float, pseudo elementos e outros) e combinações de CSS3 para componentes visuais.

Para quem se interessar, o livro está a venda online na Casa do Código (versões impressa, .mobi, .epub e .pdf).

Plataformatec na QCon SP

Aproveito para fazer o convite para assitirem o meu lightning talk sobre CSS3 Transitions e a palestra do José Valim “Uma abordagem moderna para programação na Erlang VM: Elixir” na QCon SP, neste final de semana, no dia 04 de Agosto.

Fora a minha palestra, eu estarei no stand da Casa do Código (lá na QCon). Passe por lá para bater um papo. Será um prazer! ;)
