I'm trying to read data files from a directory called 'myfiles' using a script 'app.js'.

The file to be read depends on the configurations passed to 'app.js' by another process which generates the files 'log.txt' and 'config.json'.

'app.js' then reads the files 'log.txt' and 'config.json' and fetches a data file from 'myfiles' based on the file name received.

The files in 'myfiles' are labeled my-files1.txt, my-files2.txt, my-files3.txt, ... etc.

The problem is, I keep fetching the same file 'my-files1.txt', even though 'log.txt' and 'config.json' provide new names for files to fetch.

Could you please help me spot where the problem is?

Thanks for your help!

app.js:

const fs = require('fs');

const { resolve } = require('path');

function readLog() {
    try { 
        return fs.readFileSync(__dirname + '/' + 'log.txt',  'utf8');
    }   
    catch (err) { 
        return '';
    }       
}

function readConfig() {   
    try { 
        return fs.readFileSync(__dirname + '/' + 'config.json',  'utf8');
    }
    catch (err) { 
        return '';
    }
}

let config = readConfig(); 
let log = readLog();
            
let cfg = JSON.parse(config);
let lcg = JSON.parse(log);

var currentPage = lcg.tPartition; // Current page to fetch
const numberOfPages = 10; 

if((cfg.running!=true) && (Number(currentPage)>Number(numberOfPages))){
    currentPage = 1;
}

function readDataset() {
    try { 
        return fs.readFileSync(resolve(`./app/assets/myfiles/my-files${currentPage}.txt`),  'utf8');
    }
    catch (err) { 
        return err;
    }
}

let dataset = readDataset();

const data = {
    data1: dataset // set dataset as value of data1
}

module.exports={data};
