React.js best practices and conventions. I’ve been using React.js for a little while now, both in my 9 to 5 job and for my own projects, and during that time I have started evolving my own set of React.js best practices.
The following guidelines mostly focus on component structure and JSX. However, they are not hard and fast rules, but more of an opinionated set of guidelines I choose to adhere to that make my code more readable, more robust and easily maintainable. Note: This article does not provide explanations of the React paradigms or idioms mentioned here or used in the examples, that is best left to the excellent documentation provided by the React team. Component organisation As with any code, it’s important to have consistency. I like to declare propTypes at the top of my component as they are a useful guide to a components expected usage (see section below for more on this), followed by the mixins because it is handy to initially know exactly what external behaviours the component is using/dependent on. Multi-line JSX. Writing React Components that Support the LinkedStateMixin and the valueLink Property.
In a React application, it’s very common for a component to contain state that should be editable by a child component.
The most basic example uses a text input with a value and onChange handler to display and update the text. Doing this over and over, especially in a component with a lot of controlled inputs, can get repetitive. The React addons (available when you use the “React with Add-Ons” download, or via require("react/addons") when using a CommonJS bundler) provide the LinkedStateMixin to simplify situations where an input should remain in lockstep with a given piece of state.
Now the input and the text state will remain synchronized; changing the state via setState will update the input, and changing the input will automatically call setState, updating the text key. But what does this.linkState(key), a function provided to our component by LinkedStateMixin, actually return? That means our above example could more verbosely be written like this: React JS Tutorial and Guide to the Gotchas. If you haven't used React at all, you're in the right place.

These all solve similar problems to varying degrees, and are in conflict in some ways and in harmony in others. I'm mostly concerned with the core problems of data binding and componentizing UIs. After much research and usage of the technologies mentioned above, I found React to provide the best solution. Integrating D3.js visualizations in a React app - Nicolas Hery. 07 September, 2014 A small example exploring how to integrate D3.js data visualizations into a React app.

Whenever I look into the internals of web browsers and the protocols that make the web work I usually end up feeling uneasy.
