Routes are some times better served as a modal. If you have a modal (like a login modal) that needs to be routeable and appear on all pages you may need to use query params. Will explore how to render a route all the time and use query params to control when it's content renders
In this lesson we'll explore how to combine
useState to create a reusable hook. It will listen add a window listener for
mousemove and update state with each movement.
In this lesson we'll explore how to create
useEffect call, and listen to the window for mouse movement. We'll learn about cleaning up our effects, and how to pass an empty array into the second argument of our effect to create a componentDidMount like effect. Finally we'll trigger a mount/unmount to show effects getting cleaned up correctly.
In this lesson we'll show the traditional method of updating state with a spread operator and then transform it into using the Immer produce functionality. This will allow us to achieve immutability on our data with simple mutations We'll then show how Immer can use currying to create updater functions that can be passed directly to setState.
In this lesson we'll explore how to test that an async form submission successfully happened using Jest. We'll also take advantage of react-testing-library to render our react components to a fake dom. We'll use
MemoryRouter to mock what a browser would normally do in the event of a transition, and create a fake component route to confirm that the submission successfully redirected us to the url we wanted.
In this lesson we'll explore setting up a stack navigator in React Navigation. We'll create a custom component that uses
withNavigation to allow us to listen to navigation transitions. Using the
BackHandler from React Native we can ask the screen if custom needs are required when the hardware back button is pressed. Finally we'll prompt the user if they want to navigate.
In this lesson we'll explore how to setup a draggable circle. Then we'll dive into using the
In this lesson we'll use a
PanGestureHandler to track a single gesture state. We'll use additional declarative animation functions like
event. We'll then use
interpolate to create opacity and border effects whenever the circle is dragged to new locations.
In this lesson we'll explore using Reanimated and React Native Gesture Handler to create a touchable opacity button using
TapGestureHandler. With declarative animations in Reanimated we'll use tools like
eq to create a purely native opacity animation.
In this lesson we'll explore using Reanimated and React Native Gesture Handler to create a button using
TapGestureHandler. With declarative animations in Reanimated we'll use
eq to create a purely native opacity change animation when the button is pressed.
