## What's cobalt?
|
|
cobalt is a social and media platform downloader that doesn't piss you off.
|
|
|
|
It's fast, friendly, and doesn't have any bullshit that modern web is filled with: no ads, trackers, or analytics. Paste the link, get the video, move on. It's that simple. Just how it should be.

## cobalt API
|
|
cobalt has an open API that you can use for free. It's easy and straightforward to use, [check out the docs](https://github.com/wukko/cobalt/blob/current/docs/API.md) and see for yourself.
|
|
|
|
## How to contribute translations
|
|
You can translate cobalt to any language you want on [cobalt's Crowdin](https://crowdin-co.wukko.me/). Feel free to ignore QA errors if you think you know better. If you don't see a language you want to translate cobalt to, open an issue, and I'll add it to Crowdin.
|
|
|
|
### Translation guidelines:
|
|
- All text is **ALWAYS** stylized as **lowercase** unless it's STRESSED LIKE THIS or is an internal value like `{ContactLink}` or `{appName}`.
|
|
- Example: "`this is a live video, i am yet to learn how to look into future. wait for the stream to finish and try again!`".
|
|
Notice how **everything is lowercase**, no matter the punctuation marks? Yes, that's cobalt's style and you have to follow it.
|
|
- Avoid formal language. Leave it for big and classy tech companies. Use informal language wherever possible.
|
|
- Keep translations lively, friendly, and fun. Translate strings as if the user was your buddy.
|
|
- You can (and should) rephrase sentences as long as they keep the same sense and send the same message as original.
|
|
- You can add wordplays or puns if it feels natural to do so.
|
|
- Do **NOT** use offensive or explicit vocabulary.
|
|
- Check if there are issues in UI with your localization, and optimize it accordingly. If impossible, open an issue.
|
|
- Be nice.
|
|
|
|
## Host an instance yourself
|
|
You might find cobalt's source code a bit messy, but I do my best to improve it with every commit.
|
|
|
|
### Requirements
|
|
- Node.js 17.5 or above
|
|
- git
|
|
|
|
### npm modules
|
|
- cors
|
|
- dotenv
|
|
- esbuild
|
|
- express
|
|
- express-rate-limit
|
|
- ffmpeg-static
|
|
- got
|
|
- node-cache
|
|
- url-pattern
|
|
- xml-js
|
|
- youtubei.js
|
|
|
|
Setup script installs all needed `npm` dependencies, but you have to install `Node.js` and `git` yourself.
|
|
|
|
1. Clone the repo: `git clone https://github.com/wukko/cobalt`
|
|
2. Run setup script and follow instructions: `npm run setup`
|
|
3. Run cobalt via `npm start`
|
|
4. Done.
|
|
|
|
### Docker
|
|
It's also possible to host cobalt via a Docker image, but in that case you'd need to set all environment variables by yourself.
|
|
That includes:
|
|
| Variable | Example |
|
|
| -------- | :--- |
|
|
| `selfUrl` | `https://co.wukko.me/` |
|
|
| `port` | `9000` |
|
|
| `streamSalt` | `randomly generated sha512 hash` |
|
|
| `cors` | `0` |
|
|
|
|

cobalt is my passion project, so update release schedule depends solely on my motivation, free time, and mood. Don't expect any consistency in that.
