How to Add a Route to an Express Server in Node.js
Excellently explained with clear examples, thank you!
Worked in a team that use apigee proxy to expose same endpoint to our customers and control who has access to it as so to trace it amount of request per customer. Great summary if you have more detailed info about the topic I'd be great to know it.
감사합니당
Just what I needed to get going - thank you for making this video!
great explanation, thank you.
Thank you for this great video.
Perfect! ❤ thx
An excellent tutorial. And it's exactly what I was looking for as I am about to embark on writing a simple editor for a very specific json file. I will be the sole user and the file is not terribly large, so I am not concerned about multiple users editing the file at the same time. And it's great that you have a written version of this for reference. Thank you!
Your voice is sooo soothing
but vs code white theme is killing me
Crystal clear, ty
Very Good, thank you. :)
Absolutely great and informative video!
request-promise has been deprecated
Splendid stuff.
Great and just great
je peut avoir sa en Français
Whoever you are, sir, you're a good teacher, and you should probably consider starting your own RUclips channel -- it would probably be a success.
Very good tutorial, consice and easy to understand! Thank you so much! 💛
very short and helpful i wanted to like 2 time but i recognized i already liked the video :) have great codes :D
i understood nothing :( tried my best tho
bro why you stopped making videos
How to deleted when we use 'rm -r node_modules' using GitBash on windows ?
Thank you for the tutorial, it's very informative ))) Please consider using your IDE with a dark theme when making your videos, it's hard to watch this at night 😅
tip, use dark mode
Yeah lol
This was really nice and concise
nicely done but why so small amount of watchings? That implementation of cache middleware is magnificent because i would do that with 2 such middlewares 1 in the beggining and second in the end!
Excellent series, please keep going!
Very nice. Please make us learn the same thing in Typescript as well 🙏
really helpfull !! thanks dude
i am having problem in reading and writing it is saying file not exists only way i was able to read it using require() can any one help me
how to do this in typescript?
import NodeCache from "node-cache"; import {NextFunction, Response, Send} from "express"; const cache = new NodeCache(); module.exports = (duration: number) => (req: Request, res: Response, next: NextFunction) => { if (req.method !== "GET"){ console.log('Cannot cache non-GET methods') return next() } const key = req.url; const cachedRes = cache.get(key) if (cachedRes) { res.json(cachedRes); } else { let originalJson = res.json.bind(res) res.json = (body: any): Response<any, Record<string, any>> => { originalJson(body); cache.set(key, body, duration); return res }; next(); } }
Can you please share the code? Thanks
You can find the code on our website in the full written tutorial at heynode.com/tutorial/add-response-caching-nodejs-express-server/
These short lectures on node/nom are super awesome!! Why so many less views for this series. Seems not many PPL know about this.
Yeah these are really one of the best videos to understand node system
is fetch() not a good move to use to get data from json file?
I think you would want to use fetch() if the .json file was served over HTTP and you had to request it from another server. And fs.readFile for files on the same filesystem.
Can you upload full HD videos in 1080p?
Nice tutorial! Thanks for your help
Thank you for this tuto
tout ça c'est beau mais comment on fait pour utiliser les données dans un vrai programme javascript?
Great tutorial! Just a small note: If you want to send the response as a formatted JSON, instead of text, you can use res.json instead of res.send: if (cachedResponse) { res.json(cachedResponse); } else { res.originalJson = res.json res.json = body => { res.originalJson(body); cache.set(key, body, duration); }; next(); }
Very informative!
Great content but the light theme is destroying my eyes
my eyes
Very clearly explained! :)
This error - ReferenceError: JSONReader is not defined at Object.<anonymous> - on Update code. :(
The function jsonReader() was defined earlier in the video at ruclips.net/video/HrjC6RwEpt0/видео.html, you'll need to make sure that function exists before writing the update code. Hope that helps.
thank you.
Can this NODE be used like js, without libraries buddy?
Thank you!
Seriously this video very simple and easy explanation about package.json ( please continue your video) I am from India
I keep getting an error. Javascript is possible the worst programming language.
