I went for a solution very similar to how GitHub is doing it. I've created an `iframe` and set up communication over the `postMessage` API. I was pretty much just debugging when should I fire the rendering process and whatnot. I was not bothered by handling multiple diagrams and I knew that the solution grew on complexity very quickly. On the next day, I just thought of an even simpler solution. I decided to skip the whole `iframe` shenanigans and just import the `mermaid` library dynamically into the page when the article has any diagram. This way I don't have to create any special logic around creating tokens for each diagram and the performance is even better for the client as the parsing doesn't require rendering a whole HTML document in the `iframe`. |
When I started to write this weekly I've got so deeply into writing about the error handling use case that I basically just dedicated the whole article to it. So this will be my second attempt just to not break the tradition.
Error handling guide
You can check out the new article on error handling here. It is basically a practical continuation of the first guide for error handling I've written a year ago.
Stream updates
This week we have been discussing the state of JS on the Tuesday stream. It went very well and I didn't even manage to get through it to the end. I am planning to continue on the topic when I get back from vacation on the 15th of March. I will prepare a few advertising materials (probably just a poster) and share them across social media as I want to run the stream officially.
Mermaid diagram parsing
On the Thursday stream, I've not been able to find a guest to discuss any topics so I just went for coding the diagram support for mermaid diagrams in my posts. I wanted to make render diagrams on the backend. I was very surprised that the mermaid is directly dependent on the browser to be able to render SVG. I had to rethink all over again how I would implement it.
I haven't finished it, yet. So prepare for a new article where I will present the solution. I will stream it on my twitch so if you're interested, please follow me there.
Let's keep it short. Thank you!
