Have you ever faced a situation where you’ve downloaded a JSON file from LottieFiles, only to find that the image refuses to display when you try to use it in your React application? You’re not alone! This frustrating issue has plagued many a developer, leaving them scratching their heads and wondering what went wrong. Fear not, dear reader, for we’re about to dive into the depths of Lottie-React and uncover the secrets behind this pesky problem.
What is Lottie-React, and how does it work?
Lottie-React is a popular animation library that enables developers to easily integrate animations and micro-interactions into their React applications. It’s based on the popular Lottie framework, which was developed by Airbnb. The library uses JSON files to define animations, making it easy to create and customize complex animations with ease.
So, how does Lottie-React work? Essentially, you download a JSON file from LottieFiles, which contains the animation data. You then import this file into your React component, and Lottie-React takes care of rendering the animation for you. Sounds simple, right? Well, it is – most of the time.
The Problem: Image Not Displaying
So, you’ve downloaded your JSON file from LottieFiles, and you’re excited to get started with your animation. You import the file into your React component, but… nothing happens. The image refuses to display. You’ve checked the JSON file, and it looks fine. You’ve even tried troubleshooting, but to no avail. What’s going on?
The issue lies in the way Lottie-React handles local JSON files. By default, Lottie-React expects the JSON file to be served from a remote URL. When you download the JSON file and try to use it locally, Lottie-React gets confused. It can’t find the image assets referenced in the JSON file, so it simply doesn’t render the animation.
Solution 1: Using a Local Server
One way to solve this problem is to set up a local server to serve the JSON file. This way, Lottie-React can access the file as if it were remote, and everything works as expected. Here’s how you can do it:
// Create a new folder for your project
mkdir lottie-react-example
cd lottie-react-example
// Create a new React app
npx create-react-app my-app
cd my-app
// Install lottie-react
npm install lottie-react
// Create a new folder for your JSON file
mkdir assets
cd assets
// Move your downloaded JSON file into this folder
mv ~/Downloads/animation.json .
// Create a local server to serve the JSON file
npx http-server -p 3001
// Update your React component to use the local server
import React from 'react';
import Lottie from 'lottie-react';
import animation from './assets/animation.json';
function App() {
return (
<div>
<Lottie animation={animation} loop={true} />
</div>
);
}
export default App;
In this example, we’re using the `http-server` package to create a local server that serves the JSON file. We then update our React component to use the local server URL instead of a remote URL. This trick tells Lottie-React to look for the image assets locally, and voilà! Your animation should now display correctly.
Solution 2: Using a CDN or Remote URL
Another way to solve this problem is to host your JSON file on a CDN or remote URL. This way, Lottie-React can access the file as if it were remote, and everything works as expected. Here’s how you can do it:
Option 1: Upload to LottieFiles
If you created your animation using LottieFiles, you can simply upload your JSON file to their platform. This will give you a remote URL that you can use in your React component.
import React from 'react';
import Lottie from 'lottie-react';
import animation from 'https://assets.lottiefiles.com/ animations/123456/ animation.json';
function App() {
return (
<div>
<Lottie animation={animation} loop={true} />
</div>
);
}
export default App;
Option 2: Use a third-party CDN
If you don’t want to use LottieFiles, you can upload your JSON file to a third-party CDN like GitHub Pages or Vercel. This will give you a remote URL that you can use in your React component.
import React from 'react';
import Lottie from 'lottie-react';
import animation from 'https://cdn.example.com/animations/ animation.json';
function App() {
return (
<div>
<Lottie animation={animation} loop={true} />
</div>
);
}
export default App;
Solution 3: Modify the JSON File
Another way to solve this problem is to modify the JSON file itself. When you download a JSON file from LottieFiles, it contains references to image assets that are hosted on their platform. We can update these references to point to our local image assets instead.
Let’s take a look at an example JSON file:
{
"v": "5.5.3",
"frames": {
"100": {
"t": "layer_1",
"ty": 0,
"td": 1
}
},
"assets": [
{
"id": "image_1",
"u": "https://assets.lottiefiles.com/ assets/123456/image_1.png"
}
]
}
In this example, the JSON file references an image asset hosted on LottieFiles. We can update this reference to point to our local image asset instead:
{
"v": "5.5.3",
"frames": {
"100": {
"t": "layer_1",
"ty": 0,
"td": 1
}
},
"assets": [
{
"id": "image_1",
"u": "./image_1.png"
}
]
}
By updating the JSON file to reference our local image asset, we can use it in our React component without any issues.
Best Practices for Using Lottie-React
Now that we’ve covered the solutions to the image not displaying issue, let’s take a look at some best practices for using Lottie-React in your React application:
- Use a local server or CDN: Using a local server or CDN to host your JSON file can simplify your development process and reduce the risk of issues.
- Optimize your JSON file: Make sure to optimize your JSON file by minimizing the size and compressing the data. This can improve performance and reduce load times.
- Use the correct animation format: Make sure to use the correct animation format for your JSON file. Lottie-React supports a variety of formats, including JSON, animation.json, and bundle.json.
- Test your animation: Always test your animation in different environments and scenarios to ensure it works correctly.
Conclusion
In conclusion, the mysterious case of Lottie-React and the missing image has been solved! By using one of the solutions outlined above, you can easily display your downloaded JSON file in your React application. Remember to follow best practices when using Lottie-React, and don’t hesitate to reach out if you encounter any further issues.
Happy coding!

- Frequently Asked Question
Stuck with Lottie-react and wondering why your downloaded JSON isn’t displaying images from your local repository? Worry not, friend! We’ve got you covered!
Q: Why is my image not displaying when I use the downloaded JSON in my local repository?
A: This is because Lottie-react expects the JSON file to have a valid image URL. When you download the JSON, the image URLs are not updated to point to your local repository. You’ll need to update the image URLs in the JSON file to match the path in your local repository.
Q: How do I update the image URLs in the JSON file?
A: You can update the image URLs manually or use a script to do it for you. If you’re using a script, make sure to replace the old URL with the new one that points to your local repository. For example, if the old URL is “https://example.com/image.png” and your local repository is stored in a folder called “images” in your project, you can update the URL to “/images/image.png”.
Q: What if I’m using a bundler like Webpack or Rollup? Do I need to configure it to serve images from my local repository?
A: Yes, you’ll need to configure your bundler to serve images from your local repository. This usually involves adding a plugin or configuration to tell the bundler where to find the images. For example, in Webpack, you can use the `file-loader` plugin to serve images from your local repository.
Q: Can I use a CDN to serve my images instead of hosting them locally?
A: Yes, you can definitely use a CDN to serve your images. In fact, this is a great approach if you want to reduce the load on your server or improve performance. Just make sure to update the image URLs in the JSON file to point to the CDN URL instead of your local repository.
Q: What if I’m still having trouble getting my images to display? Who can I reach out to for help?
A: If you’re still having trouble, feel free to reach out to the Lottie-react community or the maintainers of the Lottie-react library. They’ll be happy to help you troubleshoot the issue and provide guidance on how to get your images displaying correctly.
