What is it?
Today I found interesting service named Replit which is kind of online IDE for many languages, i already saw many of similar project, for example ideone, which i used in my school days for solving contest on shool computers, where compilers is not installed.
But Replit provide much more, you have a really good editor, collaborative mode, you may build complicated projects which contains multiple files, using ppular build systems, like CMake.
Interactive code in blogpost
The main feature, as i think is - your program may be interactive, you may embed this code into your blog. For example, I made a simple Snake game which you can run right now 👇
Hint: control WASD on english keyboard only
You may check source code of this game just clic to the button show files.
How to put this demo on your blog
To add repl on your site, just create a own repl on the site, and then add this iframe on your web page:
<iframe frameborder="0" width="100%" height="500px"
src="REPL_URL?embed=true"></iframe>
If you have blog on the Medium, it’s actually not possible, because they are not support user-provided iframes, so i recommend you switch to Hugo.
Thanks Erik Smith which create a tutorial how to add Replit to hugo.
