hi guys I kinda need urgent help right now. I have an assignment but currently I have a little challenge with connecting parts. Here is the task
a web app which logs calculations as they happen and shares those calculations with everyone connected to the app.currently I have implemented a calculator using React and it works perfectly I have also setup a server using node, express and socket.io my current challenge is how to get inputs from the calculator to be displayed in a form of chats which is the socket.io and node setup. Any input is appreciated.
so that, it can be easily modifiable in the future
It seems simple enough to put into practice, however I am confused on how the function is being called. Here is the meat of the file.
const asyncUtil = fn =>
function asyncUtilWrap(...args) {
const fnReturn = fn(...args)
const next = args[args.length-1]
return Promise.resolve(fnReturn).catch(next)
}Here is an example of what its use is
const asyncHandler = require('express-async-handler')
express.get('/', asyncHandler(async (req, res, next) => {
const bar = await foo.findAll();
res.send(bar)
}))Without express-async-handler
express.get('/',(req, res, next) => {
foo.findAll()
.then ( bar => {
res.send(bar)
} )
.catch(next); // error passed on to the error handling route
})I don't understand when asyncUtilWrap gets called.
I understand that asyncUtil accepts a function as an argument. In most cases it will be the callback from express. Then in the example we query are databases for all the items. At what point does asuncUtilWrap take over. By the name of it it sounds like it wraps our original function. However I have tried a few console messages within the function and I can't get it to fire off. Any help would be appreciated . Thank you!
asyncUtil is creating a closure, so the function passed to it will "initialize" the func, returning asyncUtilWrap with whatever fn was passed to it; but it'd have to invoked
node_modules file? If that's the case and you didn't see anything, it might be because you put the log into the unbuilt file rather than the built file; you'd need to find the built file usually in like lib which will be the transpiled code actually being used from the packag
I got a question please, I have built a react application with MongoDB. In the structure of my project I have 2 folders one is for the Front-end and the other for Backend. In order for me to see the actual result, I run nodemon server.js within the backend folder, and then I run on the project level npm start. My application is working perfectly.
