Google Chrome Developers says:

The new WOFF 2.0 Web Font compression format offers a 30% average gain over WOFF 1.0 (up to 50%+ in some cases). WOFF 2.0 is available since Chrome 36 and Opera 23.

Everything I Know About UI Routing

Definitions

Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
1. pathname - The "file/directory" portion of the URL, like invoices/123
2. search - The stuff after ? in a URL like /assignments?showGrades=1.
3. query - A parsed version of search, usually an object but not a standard browser feature.
4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

Idiomatic Data Fetching using React Hooks

This post has been written in collaboration with @klervicn

Virtually all web apps and websites need to pull data from a server, usually through a JSON-returning API. When it comes to integrating data fetching in React component, the "impedence mismatch" between the React components, which are declarative and synchronous, and the HTTP requests, which are imperative and asynchronous, is often problematic.

Many apps use third-party libraries such as Redux or Apollo Client to abstract it away. This requires extra dependencies, and couple your app with a specific library to perform data fetching. In most cases, what we want is a direct way to integrate plain HTTP requests (e.g. using native fetch) for usage in React components.

Here we will discuss how we can use React Hooks to do this in an elegant, scalable manner.
