In this lesson we'll show how to setup the Prompt component from React Router. We'll prompt with a static message, as well as a dynamic method with the message as a function. Finally we'll show that you can return true from the message as a function to dynamically allow navigation.

In this lesson we'll use the match.path value passed in by React Router to setup dynamic routes for Tabs. This will allow us to setup dynamic tabs which can be navigated to based upon the URL. With this pattern we can change the base path and our tab routes will automatically match and render correctly.

In this lesson we'll use scaleLinear to render a line, and additionally add data points using circle. Using onMouseMove we will call the invert function to do a reverse range to domain value interpolation. Then we will use Math.round and adjust the radius of the circle to highlight the selected point.

In this lesson we'll start by using d3-scale to build up a scaleBand for our x data and a scaleLinear for our y data points to allow them to map and extrapolate our data correctly to renderable bars. We'll add in padding between each bar, and then using the svg rect will render a collection of bars.

In this lesson we'll start by using d3-scale to build up a scaleBand for our x data and a scaleLinear for our y data points to allow them to map and extrapolate our data correctly to renderable bars. We'll add in padding between each bar, and then using the svg rect will render a collection of bars.

In this lesson we'll start by using d3-scale to build up a scaleLinear for both our x and y data points to allow them to map and extrapolate our data correctly to renderable points. Then we'll use line from d3-shape to build out our path. We'll supply it with different sets of data and explore how range can affect how our data renders. Finally we'll show off using curveStep to see how it changes our graph rendering.

In this lesson we'll show how to create an updater function. We'll also dive into how to separate your state management logic into a separate reducer function much like how Redux operates. It will receive an action with a type, and any data and update state accordingly.

In this lesson we'll show how to setup a nested validation structure using the yup library. We'll then use the yup.lazy method to evaluate the value at runtime and adjust our validation schema. We'll make our nested validation optional only if our optionalObject actually exists.

In this lesson we'll walk through building an interactive bitcoin price chart. We'll use React combined with VX to render our chart and tooltips. D3 will power all of the data processing to ensure everything is rendered where it should be. We'll also walk through explaining what scales, ranges, domains and bisectors are and how to use them.

In this lesson we'll explore using setState to synchronously update in componentDidMount. This allows for us to use getBoundingClientRect or other synchronous UI calls and make changes to the UI without a transient UI state.
