Today I would like to do some advertising. Do you know

Flems.io ?

Flems.io is a simple, but very smart prototyping platform ideal for testing oder demonstration of HTML/CSS/Javascript or even Typescript. Ok, simple might not be the right wording, it´s just super simple to use. Under the hood, it provides quite a lot:

Flems supports TypeScript, LiveScript and Babel (standalone) compilation too. You can add CSS & JS dependencies by specifying a full URL pointing to the desired file, or by giving a reference to an NPM package (and optional path) - these will be taken from unpkg.com (See the documentation for more info.)

Flems.io is similar to online editors like CodePen or JSFiddle, but has one unique selling point. You do not need an account or any external memory: Flems.io stores all data in the URL!. This is ideal for short tests and demos provided on dev.to or other online media.

Flems-URL´s can get quite long as they store all information + page settings, so you might push the limits using windows desktop links, which are limited to 256 characters. But using Flems-URL´s on online platforms like dev.to is usually not a problem. Unlike other platforms Flems.io does not require any initialization, so it is up and running in no time. It´s best usable for short demos or just for a quick test of some lines of code.

Here is an example, i alredy provided here

Happy coding!
