token-lists VS PostCSS

Uniswap tokenlist format

We’re thrilled to announce that the Crypto.com DeFi Wallet has integrated Token Lists!

I know that in order to get the addresses of every ERC20 token, https://etherscan.io/ and https://tokenlists.org/ are the way to go.

It's important to note that Uniswap is decentralized and anyone can "list" anything for trading without asking anyone or going through any process. This means there are thousands of tokens, probably millions in the future, available to trade.

Users do not see these tokens unless they actively search them out. Uniswap uses the TokenList standard (https://tokenlists.org/) and by default users only see tokens such as the top 100 projects on CoinGecko. There are many lists created by reputable players such as Aave and Gemini which cover the entire gamut of projects users want to trade without exposing end users to scam tokens.

I believe this is a good system and has worked well as having any kind of listing process or even a DAO introduces subjectivity and provides points of capture for bad actors. With an open listing process and standards like TokenLists we can say that Uniswap is truly a public good and will be around as long as we need it which provides a guaranteed way to swap any asset for any other asset no matter who created it or how controversial it is which is a good primitive for humanity to be able to rely on.

This should get you there.

the plugins in the official PostCSS website were old like IE6 or the marquee tag, and

Hello internet. I just published a new blog post on how to implement dark mode with SvelteKit, optionally with PostCSS and TailwindCSS:

There are many frontend tools available for this purpose. For example, PostCSS is a popular CSS processor that can combine and minimize your code. With the right plugin, it can even fix your code for compatibility issues, making sure your CSS styles work for all browsers.

I use PostCSS to extend CSS’s features and to add a few things that make writing styles a little more convenient, but it could easily be swapped for another preprocessor like Sass or vanilla CSS. It’s up to you. You can view my PostCSS config here.

Code transpilation isn't specific to JavaScript, You can also add a level of transformation to your CSS source using tools like post-css. Most languages with a fairly mature ecosystem will probably have some tools to help with code transformation.

In large projects, it is still a good idea to use PostCSS, which will translate new CSS features to something that browsers understand today.

LiveCodes provides many of the commonly used developer tools. These include Monaco editor (that powers VS Code), Prettier, Emmet, Vim/Emacs modes, Babel, TypeScript, SCSS, Less, PostCSS, Jest and Testing Library, among others. All these tools run seamlessly in the browser without any installations or configurations. It feels like a very light-weight version of your own local development environment including the keyboard shortcuts, IntelliSense and code navigation features.

Usually, one of the first things I do on creating a new web app is to throw a UI library in to help style components. There are several UI libraries that can be used by Svelte, but in this case I went with daisyUI because it's a fairly popular UI library which includes tailwind. To install daisyUI, you first need to install tailwind. There's a few different ways to do this (such as this guide), but the easiest way I've found is the following command, which also adds PostCSS and AutoPrefixer:

Vanilla CSS has taken a similar path with ambitious working drafts, better browser support, and PostCSS to fill the gap for user agents lagging behind. So why is Sass/SCSS still so popular? Maybe we go so used to it that we might have forgotten what problems it was meant to solve in the first place.
