nodejs fs load file code example

Example 1: node load file

const fs = require("fs");

// __dirname means relative to script. Use "./data.txt" if you want it relative to execution path.
fs.readFile(__dirname + "/data.txt", (error, data) => {
    if(error) {
        throw error;
    }
    console.log(data.toString());
});

Example 2: read file in nodejs using fs

let myFile = "./myText.txt";
const fs = require("fs");
		
app.all('/test', async (req, res) => {
	try {
		const readData = fs.readFileSync(myFile, 'utf8');
		if (readData) {
			res.send(readData)
		}
	} catch (error) {
		res.send("something is wrong", error)
	}
})
