Implement Caching for API Responses

[monilpat]

Feature Request

Is your feature request related to a problem? Please describe.

Slow API response times due to repeated data fetching.

Describe the solution you'd like

Implement caching mechanisms to store and retrieve API responses efficiently. Use a caching solution like Redis or Memcached to cache frequently requested data.

Code Example

const redis = require('redis');
const client = redis.createClient();
// Middleware to check cache
function checkCache(req, res, next) {
  const { id } = req.params;
  client.get(id, (err, data) => {
    if (err) throw err;
    if (data) {
      res.send(JSON.parse(data));
    } else {
      next();
    }
  });
}
// Route to get data
app.get('/data/:id', checkCache, (req, res) => {
  const data = getDataFromDatabase(req.params.id);
  client.setex(req.params.id, 3600, JSON.stringify(data));
  res.send(data);
});

Describe alternatives you've considered

Fetching data on every request, but this results in slower response times and higher server load.

Additional context

Caching will improve the performance and reduce server load, providing a better user experience.
