# youtube-comment-downloader
Simple script for downloading Youtube comments without using the Youtube API. The output is in line delimited JSON.

### Installation

Preferably inside a [python virtual environment](https://virtualenv.pypa.io/en/latest/) install this package via:

```
pip install youtube-comment-downloader
```

Or directly from the GitHub repository:

```
pip install https://github.com/egbertbouman/youtube-comment-downloader/archive/master.zip
```

```
$ youtube-comment-downloader --help

Download Youtube comments without using the Youtube API

optional arguments:
--help, -h Show this help message and exit
--youtubeid YOUTUBEID, -y YOUTUBEID ID of Youtube video for which to download the comments
--url URL, -u URL Youtube URL for which to download the comments
--output OUTPUT, -o OUTPUT Output filename (output format is line delimited JSON)
--pretty, -p Change the output format to indented JSON
--limit LIMIT, -l LIMIT Limit the number of comments
--language LANGUAGE, -a LANGUAGE Language for Youtube generated text (e.g. en)
--sort SORT, -s SORT Whether to download popular (0) or recent comments (1). Defaults to 1
```

For example:
```
youtube-comment-downloader --url https://www.youtube.com/watch?v=ScMzIvxBSi4 --output ScMzIvxBSi4.json
```
or using the Youtube ID:
```
youtube-comment-downloader --youtubeid ScMzIvxBSi4 --output ScMzIvxBSi4.json
```

For Youtube IDs starting with - (dash) you will need to run the script with:
`-y=idwithdash` or `--youtubeid=idwithdash`

### Usage as library
You can also use this script as a library. For instance, if you want to print out the 10 most popular comments for a particular Youtube video you can do the following:

```python
from itertools import islice
from youtube_comment_downloader import *
downloader = YoutubeCommentDownloader()
comments = downloader.get_comments_from_url('https://www.youtube.com/watch?v=ScMzIvxBSi4', sort_by=SORT_BY_POPULAR)
for comment in islice(comments, 10):
print(comment)
```
