Celebrate Your Success with a Confetti Cannon!
Who doesn’t love a good celebration? A pat on the back, a shout-out, or a festive confetti explosion can make all the difference in our daily lives. In this tutorial, we’ll show you how to create a confetti cannon that fires off any element using React Spring from scratch. No prior React Spring experience needed! Just a basic understanding of React and hooks will do.
Breaking Down the Project
When tackling a new project, it’s essential to break it down into manageable phases. Here’s our game plan:
- Get Something on the Page
Create a simple to-do app that fires confetti when you complete an item. - Set Up React Spring
Learn how to set up React Spring and create a basic confetti dot. - Write Pseudo-Physics Helpers
Make the confetti dot move like it’s being fired from a cannon. - Anchoring the Confetti
Align the confetti animation with a specific element. - Creating the Confetti Cannon
Make the confetti cannon spray a randomized fan of confetti. - Polishing the Experience
Add fade-out, randomize colors, shapes, and sizes for a more realistic effect.
Let’s Get Started!
1. Something on the Page
Create a simple to-do app that fires confetti when you complete an item. Add a single confetti dot and play with it for the next few steps.
2. React Spring Setup
React Spring is the animation library we’ll be using. It’s unique in that it uses springs rather than keyframes to create natural-looking animations. Set up React Spring with our confetti dot by installing react-spring and adding the necessary imports.
3. Pseudo-Physics
Make the confetti dot move like it’s being fired from a cannon. We’ll use React Spring to simulate the confetti’s velocity at time t. Create a spring that goes from 100 to 0, representing pixels per second.
4. Anchoring
Align the confetti animation with a specific element. Use refs to attach the animation to the checkbox and calculate the middle of the ref element.
5. Creating the Confetti Cannon
Make the confetti cannon spray a randomized fan of confetti. Randomize the initial horizontal and upward velocity of each dot, and add vertical and horizontal ranges.
6. Polishing the Experience
Add fade-out, randomize colors, shapes, and sizes for a more realistic effect. Make the confetti disappear as it falls, and add some variety to the shapes and colors.
Congratulations!
You’ve created a confetti cannon from scratch using React and React Spring. Now you should be more familiar with using React Spring’s useSpring hook to create powerful and performant animations. Get creative and make your own branded confetti cannons!
