How can I implement API caching in my Vue.js application?

You can use libraries like Axios with interceptors to cache API responses. Would you like a code example?

Yes, please provide a code example for caching.

Here's a simple example using Axios:

import axios from 'axios';

const cache = {};

const apiClient = axios.create({ baseURL: 'https://api.example.com' });

apiClient.interceptors.response.use(response => {
  cache[response.config.url] = response.data;
  return response;
});

export const fetchData = async (url) => {
  if (cache[url]) {
    return cache[url];
  }
  const response = await apiClient.get(url);
  return response.data;
};

This caches the response data based on the URL.

How do I clear the cache when needed?

You can create a function to delete specific entries from the cache or clear the entire cache object. For example:

export const clearCache = (url) => {
  if (url) {
    delete cache[url];
  } else {
    Object.keys(cache).forEach(key => delete cache[key]);
  }
};
