Cannot find file in Node even though it has correct path

Question

After executing this code:

const filename = "../../.dburl"
const url = fs.readFileSync(filename, 'utf-8')

I recieve the following error:

Error: ENOENT: no such file or directory, open '../../.dburl'

What I know so far:

1) The filepath is correct.

2) My application has permission to read the file.

3) .dburl is not read even when stored in the same directory as the application.

Any help is much appreciated ... Thanks!

Answer 1

You can use the module-level variable '__dirname' to get the directory that contains the current script. Then you can use path.resolve to use relative paths.

console.log('Path of file in parent dir:', require('path').resolve(__dirname, '../app.js'));

READING FILE ON SAME LEVEL

 //the server object listens on port 8080
    const PORT = 8080;
    var http = require("http");
    var fs = require("fs");
    var path = require("path");

    //create a server object:
    http
      .createServer((req, res) => {
        console.log("READING FILE: ", path.resolve(__dirname, "input.txt"));

        fs.readFile(path.resolve(__dirname, "input.txt"), (err, data) => {
          //error handling
          if (err) return console.error(err);

          //return file content
          console.log("FILE CONTENT: " + data.toString());
          res.write(data.toString());
          res.end();
          console.log("READ COMPLETED");
        });
      })
      .listen(PORT);

READING FILE ON OTHER LEVEL:

//the server object listens on port 8080
const PORT = 8080;
var http = require("http");
var fs = require("fs");
var path = require("path");

//create a server object:
http
  .createServer((req, res) => {
    console.log("READING FILE: ", path.resolve(__dirname, "./mock/input.txt"));

    fs.readFile(path.resolve(__dirname, "./mock/input.txt"), (err, data) => {
      //error handling
      if (err) return console.error(err);

      //return file content
      console.log("FILE CONTENT: " + data.toString());
      res.write(data.toString());
      res.end();
      console.log("READ COMPLETED");
    });
  })
  .listen(PORT);
