| | # Getting started |
| |
|
| | React Spring is a library for building interactive, data-driven, and animated UI components. It can animate HTML, SVG, Native Elements, Three.js, and more. |
| |
|
| | By the end of this quick guide, you'll have installed React Spring and created your first web-based animation! This animation will see a normal div move across the screen. |
| | |
| | ## Install |
| | |
| | React Spring can be installed with any package manager. Here's how to install it with [Yarn](https://yarnpkg.com/en/): |
| |
|
| | ### For react >= 19 |
| |
|
| | ```jsx copy="yarn add @react-spring/web" |
| | yarn add @react-spring/web |
| | ``` |
| |
|
| | ### For react < 19 |
| |
|
| | ```jsx copy="yarn add @react-spring/web@9" |
| | yarn add @react-spring/web@9 |
| | ``` |
| |
|
| | ## The Animated Element |
| |
|
| | The actual component that handles animation is our `animated` component. This is just a higher-order |
| | component (HOC) if you're familiar with that pattern. If you're not see this explanation from the |
| | `react.js` docs: |
| |
|
| | > a higher-order component is a function that takes a component and returns a new component. |
| |
|
| | So really, it's just a fancy wrapper. To use it, we need to import it: |
| | |
| | ```jsx copy="import { animated } from '@react-spring/web'" |
| | import { animated } from '@react-spring/web' |
| | ``` |
| | |
| | We use our animated component like any other JSX element and to ensure we can see it, we'll add some styling: |
| |
|
| | ```jsx defaultOpen=true line=5 |
| | import { animated } from '@react-spring/web' |
| |
|
| | export default function MyComponent() { |
| | return ( |
| | <animated.div |
| | style={{ |
| | width: 80, |
| | height: 80, |
| | background: '#ff6d6d', |
| | borderRadius: 8, |
| | }} |
| | /> |
| | ) |
| | } |
| | ``` |
| |
|
| | Now we're ready to add our hook & animate the component! |
| | |
| | ## The Hook |
| | |
| | Meet your first hook, our signature hook really – `useSpring`, first we need to import it: |
| | |
| | ```jsx copy="import { useSpring, animated } from '@react-spring/web'" |
| | import { useSpring, animated } from '@react-spring/web' |
| | ``` |
| | |
| | To use `useSpring`, we treat it like any other hook: |
| | |
| | ```jsx line=4-8 |
| | import { useSpring, animated } from '@react-spring/web' |
| | |
| | export default function MyComponent() { |
| | const springs = useSpring({ |
| | from: { x: 0 }, |
| | to: { x: 100 }, |
| | }) |
| | |
| | return ( |
| | <animated.div |
| | style={{ |
| | width: 80, |
| | height: 80, |
| | background: '#ff6d6d', |
| | borderRadius: 8, |
| | }} |
| | /> |
| | ) |
| | } |
| | ``` |
| | |
| | We use the keywords `from` and `to` to define the start and end values of our animation. |
| | So in this instance, we're starting with an `x` value of 0 and ending with a value of 100. |
| |
|
| | ## Your First Animation |
| |
|
| | `useSpring` doesn't actually animate anything though. It just returns `SpringValues` that we pass to |
| | our animated component. So that when the springs are applied and the component is mounted it will |
| | move to the right. These springs are passed to the animated component like so: |
| | |
| | ```jsx live=true defaultOpen=true line=10 |
| | import { useSpring, animated } from '@react-spring/web' |
| | |
| | export default function MyComponent() { |
| | const springs = useSpring({ |
| | from: { x: 0 }, |
| | to: { x: 100 }, |
| | }) |
| | |
| | return ( |
| | <animated.div |
| | style={{ |
| | width: 80, |
| | height: 80, |
| | background: '#ff6d6d', |
| | borderRadius: 8, |
| | ...springs, |
| | }} |
| | /> |
| | ) |
| | } |
| | ``` |
| | |
| | And there we have it! Your first animated component. |
| | |
| | ## Reacting to events |
| | |
| | Very rarely do you find yourself only needing an animation to occur only on mount, |
| | we normally want animations to occur on a user interaction. Whether that's |
| | `mouseenter`, `click`, `keydown` or any event that could occur. So how do we do |
| | this very common use-case? |
| |
|
| | `useSpring` can take two types of first argument, a `config` object and a `function`. |
| | We're going to explore the latter in more detail, we'll start by changing the notation of our hook. |
| |
|
| | ```jsx line=4-6 |
| | import { useSpring, animated } from '@react-spring/web' |
| |
|
| | export default function MyComponent() { |
| | const [springs, api] = useSpring(() => ({ |
| | from: { x: 0 }, |
| | })) |
| |
|
| | return ( |
| | <animated.div |
| | style={{ |
| | width: 80, |
| | height: 80, |
| | background: '#ff6d6d', |
| | borderRadius: 8, |
| | ...springs, |
| | }} |
| | /> |
| | ) |
| | } |
| | ``` |
| |
|
| | When we provide a function to `useSpring` we get an array returned, with the first |
| | argument as our `springs` which we're already used to (as this is returned when you |
| | provide only a config object) and the second argument is the `api` that controls |
| | these springs. |
| | |
| | We'll start with a very basic user interaction, the `onClick` event by creating a |
| | handler and in that handler we'll use the `api.start` method. The `start` method starts |
| | our animation with the configuration we provide to it, like so: |
| | |
| | ```jsx live=true defaultOpen=true line=8-18 |
| | import { useSpring, animated } from '@react-spring/web' |
| | |
| | export default function MyComponent() { |
| | const [springs, api] = useSpring(() => ({ |
| | from: { x: 0 }, |
| | })) |
| | |
| | const handleClick = () => { |
| | api.start({ |
| | from: { |
| | x: 0, |
| | }, |
| | to: { |
| | x: 100, |
| | }, |
| | }) |
| | } |
| | |
| | return ( |
| | <animated.div |
| | onClick={handleClick} |
| | style={{ |
| | width: 80, |
| | height: 80, |
| | background: '#ff6d6d', |
| | borderRadius: 8, |
| | ...springs, |
| | }} |
| | /> |
| | ) |
| | } |
| | ``` |
| | |
| | The `api` value has many different methods that we can use to control our animation. |
| | We can `stop` our animations, we can `set` them (to change the value without animation) |
| | and much more. |
| | |
| | ## Next Steps |
| | |
| | Whilst this was a brief introduction to `react-spring`, through this tutorial you've |
| | learnt about these three key areas: |
| |
|
| | - the `animated` component and how to use it with HTML elements |
| | - the `useSpring` hook with either a configuration object or with a function |
| | - how to use the `api` object to control your animation and react to events |
| |
|
| | From here, you could learn how to use our other hooks or more about the configuration |
| | objects we pass to the animation hooks. |
