I was using readdirsync() to get all the file names in a directory then send it to the front end and it works fine. The problem is if a new file is created in the directory after readdirsync run it the won't update the files name array to send to the back end. How can I listen if a new file exists and resend the data to the client-side without having to reload the server manually? Is this possible? Any help is appreciated. Thanks in advance.
const fs = require("fs");
var currentData = []
fs.readdirSync('./dirPATH').forEach(file => {
currentData.push(file);
});
//what i tried but this won't work. still requires manual server restart:
function dataExchange() {
app.post("/getData", (req, res) => {
try {
res.send(currentData);
} catch (error) {
console.log(error);
res.status(400);
}
})
}
dataExchange()
setInterval(() => {
dataExchange()
}, 2000)
