Node JS Insert text from file to name result file from Puppeteer scrap-CodePudding

I am hacking together a node script in Puppeteer where I scrap a webpage and safe the content as a text file where I name the file after the date and want to add text from a text file at the end of the name.

const puppeteer = require('puppeteer');
const fs = require('fs');

let utc_date_string = new Date().toLocaleString("en-US", { timeZone: "UTC" });
let date_utc = new Date(utc_date_string);
let year = date_utc.getFullYear();
let month = ("0"   (date_utc.getMonth()   1)).slice(-2);
let date = ("0"   date_utc.getDate()).slice(-2);
let hours = ("0"   date_utc.getHours()).slice(-2);
let minutes = ("0"   date_utc.getMinutes()).slice(-2);
let time_hh_mm = hours      minutes;
let data = fs.readFileSync('insert.txt', 'utf8');

(async () => {
  const browser = await puppeteer.launch(
{
    headless: true,
    args: ['--single-process', '--no-zygote', '--no-sandbox']
  })
  const page = await browser.newPage()
await page.goto('https://example.com/xxx.html>
  const myproblem = await page.$eval('table', table => table.innerText)

fs.writeFile('/var/www/mydomain.com/xxx/' year '-' month '-' date '-' time_hh_mm '-' data '.txt', myproblem, e>
  await browser.close()
})()

This works so far but the problem is that the file name comes out like this

'2022-02-13-1453-test_text_insert'$'\n''.txt'

and not like this

2022-02-13-1453-test_text_insert.txt

If I use only the date, the file name comes out as expected. I don't know from where the extra characters come from (they are not in the text file) or if there is something wrong with the code.

CodePudding user response：

String error. You should check this line:

let time_hh_mm = hours      minutes;

Maybe it should be like this: (?)

let time_hh_mm = hours   minutes;

And you tried to read the file which contain the breakline character \n, you can try to trim it.

fs.writeFile('/var/www/mydomain.com/xxx/' year '-' month '-' date '-' time_hh_mm '-' data.trim() '.txt', myproblem)
