Proposal for lightning talk at Reactive Conf 2015

I’m amazed by React and how it’s bringing happiness to our developer lives. I specially like the workflow that integrates Webpack + React + CSS Modules + Babel among other tools and preprocessors. That’s why Javier Jiménez and I are working together in a library called React Toolbox that we would like to show in a lightning talk at Reactive Conference.

The main idea is to create a set of React components implementing Material Design guidelines. There are already some libraries that solve a similar problem but our project is mostly focused on the workflow and best practices to create a tool everybody would want to use. Also, we are sticking to the design guidelines proposed by Google and embracing minimalism by generating the minimum possible amount of HTML and styles to get the best result. Our workflow includes among others:

  • Webpack.
  • ES6 with Babel
  • Unit t

Basic steps for hosting on Github

Hey there, apparently people are still using this Gist from 2013! It's out of date! Consult the Github docs.

Steps for Hosting a Website on GitHub

  1. Create a GitHub account on github.com.
  2. Download either [GitHub for Mac][1] or [GitHub for Windows][2], depending on your operating system. Open the app and log in using the account you just created.
  3. (On Mac): After you login, click advanced and make sure that your name and email are correct. Then, click "Install Command Line Tools", just in case you want to start using the command line later in life.
  4. Create a new repository in your GitHub application. Name it your-username.github.io. The name is very important. Note the folder that GitHub is saving the repository to. Make sure the "Push to GitHub?" box is checked.
  5. Move your website's files into the folder that GitHub just created when you made the repository. IMPORTANT: Your homepage HTML file must be called "index.html", and it must exist in the top-level
