Thanks for this tool. I use it a lot.

I have an issue downloading a specific course.

trying to download https://coursehunters.net/course/progressivnye-veb-prilozheniya-v-react-s-create-react-app does not work,

the videos.txt file is completely empty

output:

Starting app...

File progressivnye-veb-prilozheniya-v-react-s-create-react-app/videos.txt already exists

it quits afterwards.

Feature Request: Formatting and Padding zeros

CH provides unpadded course numbers:

lesson1.mp4
lesson2.mp4
...
lesson10.mp4

Some video players (MPV) require padding.

lesson01.mp4
...
lesson20.mp4

three zeros for more than a 100 video:

lesson001.mp4
...
lesson010.mp4
...
lesson100.mp4

Another thing is that on linux, it is more than recommended to not have spaces on your files so, you don't have to escape them. this is a command line app after all.

not only that this is unreadable, but also unusable. If you want to change the path you have to press ctrl+w a number of times and it's frustrating. I would suggest kebab-case (lowercase included) at least for linux.

Doesn't work

Will it work ever again? I can't even download a simple free course off.

Coursehunters site is redesign So its not working

findNotExistingVideo not working properly

ch-download/index.js

Line 85 in 4883cd4

const name = data.names[i].toString().replace(/[^A-Za-zА-Яа-я\d\s]/gmi, ''); // alelov

should add .replace('Урок ', '') to the end of this line, for making findNotExistingVideo.js works properly.
(for now in findNotExistingVideo.js, comparing videos and existing files will always result in false because video.name is like "Урок 1 xxxxx", while existing filename is like "1 xxxxx", remove the 'Урок ' prefix of video.name will fix the issue)

Feature Request: Custom Directory To Still Use Course Name Folder

Feature:

ch-download to download videos and put them in a folder with a custom directory set.
a -D captial d flag to do that?

Motivation:

I have a shell alias that can be called anywhere node ~/absolute/path/to/index.js -e email -p password -d ~/media/courses -u and would love to not have to worry about naming the directory inside media/courses and still use a custom one.

Check your e-mail or password

Hi! The app refuses to work with valid credentials. Yesterday everything was fine. I'm able to log in on coursehunters with these credentials and see the course. Password doesn't contain any special symbols, tried to screen it with single quotes, got no success.

Unable to get premium

Hi!

I have been trying to pay for premium access but could not. Could it be the merchants you guys use? I am a subscriber from West Africa.

npm install -g https://github.com/alekseylovchikov/ch-download
this is not working, should use the good old $>node index -u <url> or do a proper npm publish

This is a great tool that helps me so much! I use it on a raspberry pi to collect courses when sleeping! Really love your guys' amazing work!

Can you publisher the current verison in npm?
the package in npm website version was 0.0.6, so could you publisher?

Wrong password

Seems like CH is changed their Auth API. I've tried with right password but showing wrong password again and again.

curl --location --request PUT 'https://coursehunter.net/api/auth/login' \

Please check the course url or This course is only available to premium users!

I have purchased the premium version of coursehunter and still I am getting this error.

The url link is https://coursehunter.net/course/full-stack-instagram-klon-2-0

Error: check your email or password

Hello there!
I find out that if your password starts with $ sign then app will throw an error Check your email or password. So now I need to escape this sign with backslash.
It will be nice if you can fix this issue.
Cheers!

Please check fix after coursehunter updated there API

Check PR with update API endpoinds for lessons #61

CLI stopped downloading courses because CH changed slightly structure of the website

Add my pull request when added downloading subtitles and materials from course

I think this will be useful to many.
Since I saw a request to download subtitles in the chat site

Videos not downloading

I am having an issue where the downloader starts but says creating videos.txt and then stops and nothing is downloaded , a video.txt file of 0kb is created (blank)

Ошибка TypeError [ERR_UNESCAPED_CHARACTERS]: Request path contains unescaped characters

Feature Request: Skip download materials

When we download the course videos one after another, the download materials are downloaded every time we run the code.
Some of them are very large in size and they are not necessary.
Users should be able to choose whether to download the download materials or not.
Adding the choice as an argument in the code could help.

Error while downloading

В функции createFolder(downloadFolder) когда происходит проверка на наличие директории / на Mac функция fs.mkdirSync(curDir) возвращает код ошибки EISDIR который сейчас никак не обрабатывается и падает с ошибкой "Check your email or password".

Рабочая функция:

function createFolder(downloadFolder) {
  const sep = path.sep;
  const initDir = path.isAbsolute(downloadFolder) ? sep : '';
  downloadFolder.split(sep).reduce((parentDir, childDir) => {
    const curDir = path.resolve(parentDir, childDir);
    try {
      fs.mkdirSync(curDir);
    } catch (err) {
      if (err.code !== 'EEXIST' && err.code !== 'EISDIR') {
        throw err;
      }
      if (curDir == makeDownloadFolderPath(downloadFolder))
        console.log(`Directory ${curDir} already exists`.blue);
      return curDir;
    }
    console.log(`Directory ${curDir} created`.blue);
    return curDir;
