* Update Lifting State Up not to mix up DOM value with component state A few weeks ago when teaching my friend, she got stuck on `this.state.value` vs. `event.target.value`. As the documentation talked a lot about "values", and the term value could mean three different things (values in general, the "value" prop / DOM value of the <input> component and the value in state/props), it was not weird that she got a bit confused. * Rename Lifting State Up onChange props to onTemperatureChange This is in-line with how the temperature is provided as a prop named `temperature` * Fix one value prop not being renamed to temperature * Update codepen examples in Lifting state up documentation * Update devtools state change to reflect docs change
React Documentation & Website
We use Jekyll to build the site using (mostly) Markdown, and we host it by pushing HTML to GitHub Pages.
Installation
If you are working on the site, you will want to install and run a local copy of it.
Dependencies
In order to use Jekyll, you will need to have Ruby installed. macOS comes pre-installed with Ruby, but you may need to update RubyGems (via gem update --system).
Otherwise, RVM and rbenv are popular ways to install Ruby.
The version of the Pygment syntax highlighter used by Jekyll requires Python 2.7.x (not 3.x). macOS comes pre-installed with Python 2.7, but you may need to install it on other OSs.
- Python (version 2.7.x)
Once you have RubyGems and installed Bundler (via gem install bundler), use it to install the dependencies:
$ cd react/docs
$ bundle install # Might need sudo.
$ npm install
Instructions
The site requires React, so first make sure you've built the project (via grunt).
Use Jekyll to serve the website locally (by default, at http://localhost:4000):
$ cd react/docs
$ bundle exec rake
$ bundle exec rake fetch_remotes
$ bundle exec jekyll serve -w
$ open http://localhost:4000/react/index.html
We use SASS (with Bourbon) for our CSS, and we use JSX to transform some of our JS. If you only want to modify the HTML or Markdown, you do not have to do anything because we package pre-compiled copies of the CSS and JS. If you want to modify the CSS or JS, use Rake to compile them:
$ cd react/docs
$ bundle exec rake watch # Automatically compiles as needed.
# bundle exec rake Manually compile CSS and JS.
# bundle exec rake js Manually compile JS, only.
Afterthoughts
Updating facebook.github.io/react
The easiest way to do this is to have a separate clone of this repository, checked out to the gh-pages branch. We have a build step that expects this to be in a directory named react-gh-pages at the same depth as react. Then it's just a matter of running grunt docs, which will compile the site and copy it out to this repository. From there, you can check it in.
Note: This should only be done for new releases. You should create a tag corresponding to the release tag in the main repository.
We also have a rake task that does the same thing (without creating commits). It expects the directory structure mentioned above.
$ bundle exec rake release
Removing the Jekyll / Ruby Dependency
In an ideal world, we would not be adding a Ruby dependency on part of our project. We would like to move towards a point where we are using React to render the website.
