# awesome-data-hoarding



A concise cheat-sheet of commands and tools for scraping, saving, hoarding, archiving, collecting, organising and browsing data.



Inspired by Reddit's [/r/DataHoarder](https://www.reddit.com/r/DataHoarder/)



## Quick reference



Which archiving tool should you choose for each web service?

## Techniques



### Combine streamed .ts files and m3u8 playlist/chunklist into an mpeg/mp4 video



- After extracting the .m4u8 and .ts files from HAR, run something like:

  - `ffmpeg -i playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4`



### Extract playlist data from YouTube and YT Music



Input: https://music.youtube.com/library/playlists

Goal: Extract a list of playlists suitable for feeding to youtube-dl / yt-dlp



These are all equivalent ways to achieve the same thing:

1. Chrome: Save As | Web Page, HTML Only --> doesn't work, empty page

1. Chrome: Save As | Web page, Single File --> works, full HTML, embeds images, uses "quoted printable encoding", i.e. `=` becomes `=3D`

1. Chrome: Save As | Web page, Complete --> works, full HTML, not encoded, saves album/playlist covers as image files.

1. Chrome: DevTools | Elements |  | right-click | Copy | Copy element | Paste into text editor --> works, full HTML

1. Chrome: Extensions | XPath Helper | Ctrl-Shift-X | Hover over element | Shift | Edit XPath to remove e.g. `[409]` | Append `/@href` --> works, list of URLs

1. Chrome: DevTools | Console | [](https://stackoverflow.com/a/7474386) | [](https://stackoverflow.com/a/20495940) | `$(document).xpathEvaluate('//body/div/foo')`

1. Chrome: DevTools | Elements | right-click | Copy | Copy JS | (paste into console and edit - see snippet below)

1. Chrome: Extensions | AutoHAR | chrome --auto-open-devtools-for-tabs | ...etc

1. Chrome: DevTools | Network | Filter | Fetch/XHR | https://music.youtube.com/youtubei/v1/browse/...etc... | (a) Save all as HAR with content, (b) (down-arrow near top-right) Export HAR... 

1. (Idea) Headless chrome + puppeteer or playwright



Javascript snippet:

    

```

items = document.querySelectorAll("#items > ytmusic-two-row-item-renderer");

items.forEach((item) => {

    drill = item.querySelector("div.details.style-scope.ytmusic-two-row-item-renderer");

    span = drill.querySelector('span > yt-formatted-string > span:nth-child(3)');

    if (! span) { return };

    console.log(

        drill.querySelector('a').toString()

        + "    " + span.innerHTML

        + "    " + drill.querySelector('a').text

    );

});

```



Shorter snippet:

```

var output = '';

document.querySelectorAll("h3 > div > div > a").forEach((item) => { output += item.text + "\n"; });

console.log(output);

console.save(output);

```

### Case studies



- **naive-slack-scraper**. Hypothetical code that cannot exist, as it potentially wouldn't follow terms of service. So don't look for it.

- [pokemon-data](https://github.com/pokemon-names/pokemon-data/blob/main/data/README.md). jq examples.

- [moar jq examples](https://wills-tech-notes.blogspot.com/2022/08/jq-cheat-sheet.html)



## Discussion



- If an archive of data is made, and that data cannot be viewed reasonably easily in a way similar to its original presentation by a person on the street, then it can be considered not to be viewable at all. It may as well not exist for public purposes. A possible retort is to assert "A viewer program could be built". But if that viewer program doesn't yet exist, then the data still can't be viewed. It's a Schroedinger's archive.
