With sass-link you can use sass and scss alomst like regular css. It parses the <link> and <style> tags of your document, compiles them using sass.js and injects the compiled css back into the document.

You can add <link> tags that refer to .sass or .scss files:

<link rel="stylesheet" type="text/scss" href="main.scss">

You can also use sass and scss inside <style> tags:

<style type="text/scss">
  /* scss */

To get started, add sass.js and sass-link to your document:

<script src="https://cdn.jsdelivr.net/combine/npm/sass.js@0.10.10/dist/sass.sync.js,gh/slymax/sass-link@0.1.3/sass-link.js"></script>

Your styles will only be compiled if the type attribute is set to text/sass or text/scss.

To avoid seeing the unstyled document before your stylesheets have compiled, you can add the sass-cloak attribute to your <body> along with some css to hide it:

  [sass-cloak] {
    display: none;
<body sass-cloak>

Only use sass-link for prototyping. It should not be used in production.

The source code is available on GitHub.

Panic is a script to panic sell cryptocurrencies.

  1. Download or clone the repository and run npm install to install dependencies.
  2. Open the config.json file and add the API keys for your exchanges.
  3. Run npm start to launch the script.

As long as the trade property in config.json is set to false, Panic will only show you what transactions would be executed without actually placing any orders. If you set it to true, orders will be executed without prompting for confirmation.

In config.json you can also specify your target currencies. The default setting is ["EUR", "USD", "USDT", "BTC"] which means that Panic will try to exchange each token for Euros first. If that pair is not available for trading on the exchange, it will try to exchange for USD, then for USDT, etc. I recommend leaving BTC as the final option so that if a token can't be directly exchanged for fiat, it will be exchanged for Bitcoin. You can then run the script again to exchange your remaining Bitcoins for fiat. You can also overwrite the global target setting for individual exchanges.

Panic is powered by CCXT and requires Node.js 8 or higher. The source code is available on GitHub.
