Make more videos on JavaScript projects and nodejs projects

[@l-_._-l]

we can almost anything related to file e.g create edit delete these are not available in normal js const fs = require("fs") there are two types of commands for file handling sync and async // sync can return value that we can store in a variable const data = fs.readFileSync("file.txt", "utf8"); console.log(data); // sync requires a try and catch to handle error const fs = require('node:fs'); try { const stats = fs.statSync('/Users/joe/test.txt'); } catch (err) { console.error(err); } // async can't return value so we can't store it in a variable fs.readFile("file.txt", "utf8", (err, data) => { console.log(data); }); // async needs a call back where we can handle error const fs = require('node:fs'); fs.stat('/Users/joe/test.txt', (err, stats) => { if (err) { console.error(err); } // we have access to the file stats in `stats` });

[@2ameridiem]

can we use the fs module to access any file on our system? or is it just for the files present in our current directory?

[@noobcoder1687]

bro, can you please write code in the ES6 way, since I am just start learning , I want to start with the best practice in place. Also can you show everything in class way, how people use them in production. Please talk about socket API as well.. I tried the P2P project, google meet like conferencing tutorial of yours and find it difficult. So, if you kindly talk about the basics, then that would be real help

[@piyushgargdev]

Don't Worry! We are going to cover each and everything in this playlist and make super easy for you to understand. After this playlist you'll be able to follow P2P as well with ease.

Summary: Create file writeFileSync writeFile For read a file readFileSync readFile = expect call back func append in file appendFileSync Copy file cpSync For delete file unlinkSync For Statics statSync For creating a folder mkdirSync

[@eternal423]

Thank you❤

[@dhritika-j2t]

just wow

[@inderjeet09]

Bro there is a issue when using appendSync function your file appends the given text every time you run your code but in my case I am using same code but my text is appended only once and then remains same even if I run it 5 times Please describe why is it so.

[@mr.incognito611]

you need to comment out the writeFileSync and readFileSync lines . The reason is everytime the file.js is getting executed the writeFIleSync is deleting the previous demo.txt and creating a new demo.txt with the content passed to it and then it's appending the content of the appendFileSync .

[@pratikshanikam2503]

explained very clearly thank you sir!!!!!!!
