In Vite, JSON files can be excluded from bundling by using the rollup.config.js file in your project directory. By specifying a custom Rollup configuration, you can exclude certain files or extensions from being bundled. To exclude JSON files specifically, you can use the exclude option in the Rollup configuration to prevent them from being bundled along with your JavaScript files. This way, JSON files will be served separately and not included in the final bundle generated by Vite.

What are the different ways to load JSON files in Vite applications?
There are several ways to load JSON files in Vite applications:
- Using import statement: You can simply use the import statement in your JavaScript or TypeScript code to import the JSON file as a module. Vite supports importing JSON files out of the box. For example: import data from './data.json';
- Using dynamic import: You can also use dynamic import to load JSON files lazily. This can be useful when you want to load the JSON file only when it is needed. For example: const fetchData = async () => { const data = await import('./data.json'); console.log(data); }
- Using Fetch API: Another way to load JSON files in Vite applications is to use the Fetch API to make a network request to fetch the JSON file. For example: const fetchData = async () => { const response = await fetch('./data.json'); const data = await response.json(); console.log(data); }
- Using plugins: There are Vite plugins available that can help you load JSON files in different ways, such as vite-plugin-vue-inject or vite-plugin-mock.
- Using Axios or other HTTP client libraries: You can also use libraries like Axios to make HTTP requests and load JSON files in your Vite applications. For example: import axios from 'axios'; const fetchData = async () => { const response = await axios.get('./data.json'); console.log(response.data); }
How can I access JSON data directly from external files in Vite?
To access JSON data directly from external files in Vite, you can use the fetch API to fetch the JSON data from the external file and then parse it as JSON.
Here is an example of how you can do this in your Vite application:
- Create a JSON file (e.g., data.json) in the public folder of your Vite project.
- Add some JSON data to the data.json file.
- In your Vue component or JavaScript file, use the fetch API to fetch the JSON data from the data.json file and parse it as JSON.
1 2 3 4 5 6 7 8 9 |
// Vue component or JavaScript file fetch('/data.json') .then(response => response.json()) .then(data => { console.log(data); // JSON data from data.json file }) .catch(error => { console.error('Error fetching JSON data:', error); }); |
Make sure to replace /data.json with the correct path to your JSON file relative to the root of your project.
By using the fetch API in this way, you can access JSON data directly from external files in your Vite application.
How can I include JSON files in Vite project without bundling?
To include JSON files in a Vite project without bundling, you can use the import syntax in your Javascript or Typescript files to directly import the JSON files. Vite supports the ES Module syntax, so you can simply import the JSON file like you would import any other module.
Here's an example:
- Create a JSON file in your project, for example, data.json:
1 2 3 4 |
{ "name": "John Doe", "age": 30 } |
- In your Javascript or Typescript file, you can import the JSON file as follows:
1 2 3 |
import data from './data.json'; console.log(data); |
When you run your Vite project, the JSON file will be loaded directly without bundling. This is possible because Vite is a build tool that leverages ES Module imports to provide fast and efficient development and production builds.
