The latest version of redis is asynchronous so no need to make custom functions. You can simply use the client. For instance, const reply = await client.GET(`rockets`) await client.setEx("recipes", 5, JSON.stringify(response.data)) const reply = await client.GET(`rocket-${id}`) await client.setEx(`rocket-${id}`, 5, JSON.stringify(response.data))

Thx Man ! I'm using Redis for my own project and it's working so far. But I didn't know about the built in promisify function in node lol. I can say it helps a lot because it's was a hard work to deal with the callback on each Redis GET function ( GET, HGET, HGETALL ... ). I was watching this kinda video just to find things like this, little but very helpful. This video is one top of that very clear for beginners.

Still useful, since redis is in-memory so reading from memory is way faster than reading from disk.

How can we display cached data from redis into html , res.render() ? Since we have the data stringified before to save it. Thanks.

@mafiacodes 3 жыл бұрын

If ur doing server side rendering, then u shud use a templating engine like “EJS”, you can watch this video to see how ejs works kzfaq.info/get/bejne/eL6lhZmmyNnHep8.html though it’s a video to create short links but ejs part remains the same.

@ShwetaSingh-nw3nq 3 жыл бұрын

@@mafiacodes Actually my questions was incorrect, it was about caching the html itself and rendering cached html rather than data(json). Wanted to implement this: res.render('showList',{shows:data},async(err,html)=>{ await client.setAsync('movieList',html); res.send(html); Thank you. I watched the ejs video too.

That's so wrong intro. Use caching when data is fetched often. Not when data doesn't change often

@mafiacodes 3 жыл бұрын

A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. In a messaging app or notifications - data is fetched quickly, so should you cache - NO.
