APP压力测试年末特惠

// 使用Webpack进行资源打包和压缩
module.exports = {
  optimization: {
    minimize: true,
    splitChunks: {
      chunks: 'all',
    },
  },
};

// 图片懒加载
const images = document.querySelectorAll('img[data-src]');
const observer = new IntersectionObserver((entries, observer) => {
  entries.forEach(entry => {
    if (entry.isIntersecting) {
      const img = entry.target;
      img.src = img.dataset.src;
      observer.unobserve(img);
    }
  });
});
images.forEach(img => observer.observe(img));

# 使用Flask框架和Redis缓存
from flask import Flask
from redis import Redis

app = Flask(__name__)
cache = Redis(host='redis', port=6379)

def get_data(key):
  data = cache.get(key)
  if data is None:
    data = fetch_from_database(key)
    cache.set(key, data)
  return data

@app.route('/')
def index():
  data = get_data('important_key')
  return data
