Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Turns out showdown requires strict tabling, seen in https://github.com/showdownjs/showdown/issues/666

How do I display a markdown table on a website with go backend?
So you're going to need a Markdown parser that produces HTML. But there's a question of where is the data coming from and where you you want to process it? If it's going to be all on the frontend like a text editor, use a JS library for it (a quick google search produces ShowdownJS)

Docusaurus first impression and stealing like an open sourcer
Previously, I was required to implement the markdown support manually which meant that the use of public libraries was prohibited. My tool could only support limited styling elements such as header1, header2, links, bold and italics, but now I can finally let my tool have a full markdown support by using Showdown.

I made a full-stack portfolio site using Next.js and Tailwind!
The first two ages are very heavy on content so I decided to use markdown and tailwind’s typography plugin for styling. I also used showdown to fetch the markdown and turn it into HTML. The code for the above can be found on the site’s GitHub repository.

Working on a no-code data notebook. You can quickly pull data from platforms like Stripe and do complex analysis without writing SQL, all within a Notion-style interface. Thoughts?
I'm using https://github.com/showdownjs/showdown for the core rendering-markdown functionality, with a bunch of additional listeners etc on top of it to fit it into the notion-style UX! Hope that helps :)

As you can see the content is returned as markdown - it's much more efficient to send the data this way, but in our frontend app we'll need to convert it to HTML. We'll probably use something like Showdown.

A Colorful Textarea
Adding syntax highlighting to an input field can be a hard task. supports neither styling of individual characters or words, nor HTML tags within itself, there is no fully supported native solution for that. Most editors work with
contenteditable
to actually render a fully marked up code snippet and let the user edit its content. This requires a lot of work to get it accessible (as in restore all the native functions of a textarea) and still adds a lot of complexity.
If you don't want that and are just looking for a quick, dead-simple solution: Here's how to colorize a textarea.Solution
The trick is to separate the input element from the displayed one. We can't color the content of a textarea, but we can make it invisible and replace it with marked up content. This works with monospaced fonts and fonts with a uniform width across normal, bold and italic characters. I'm using this for code and markdown, so that's perfectly acceptable for me. We also need to be careful to match the dimensions of the textarea exactly while only using font-relative units like
em
, to ensure that the highlight element scales well with the invisible textarea. The cursor is still in the textarea's context, while the text itself is rendered in the highlight element. We want to match every character of the textarea to match the highlighted one on a pixel-perfect basis.I also need to auto-resize my textarea. Since textareas usually scroll vertically, that would mess up the position matching with the highlight element. Auto-resizing seems like a graceful workaround to me.
The highlghting itself would work with every code parser. I'm using highlight.js to convert markdown to syntax-highlighted HTML. I listen for content changes in the textarea and parse new rendered code on every input. To counter the worst performance hits, I'll just use
requestAnimationFrame
. Debouncing isn't an option here, because the user would only see what they've written after they've finished typing. That'd be very poor UX.Demo
Note that this example also displays the rendered Markdown in a separate element. I'll use the change listener that I already have to splice in a Markdown renderer: Showdown.
Pros
- as accessible as a textarea
- is a progressively enhanced feature
- can be styled exactly to your needs
- dead simple solution compared to a rich text editor
Cons
- has performance issues with large texts (as do textareas in general)
- works only with monospaced fonts
- works only with auto-sizing textareas

From Flaky to Flawless: Angular API Response Management with Zod
Zod is an open-source schema declaration and validation library that emphasizes TypeScript. It can refer to any data type, from simple to complex. Zod eliminates duplicative type declarations by inferring static TypeScript types and allows easy composition of complex data structures from simpler ones. It has no dependencies, is compatible with Node.js and modern browsers, and has a concise, chainable interface. Zod is lightweight (8kb when zipped), immutable, with methods returning new instances. It encourages parsing over validation and is not limited to TypeScript but works well with JavaScript as well.

You can’t run away from runtime errors using TypeScript
Zod is a TypeScript-first schema declaration and validation library. It helps create schemas for any data type and is very developer-friendly. Zod has the functional approach of "parse, don't validate." It supports coercion in all primitive types.

What even is a JSON number?
In JS, it's a good idea anyway to use some JSON parsing library instead of JSON.parse.
With Zod, you can use z.bigint() parser. If you take the "parse any JSON" snippet https://zod.dev/?id=json-type and change z.number() to z.bigint(), it should do what you are looking for.

Zod: Zero to Hero - Chapter 1
I was first introduced to Zod by Adam Bobrow - a colleague of mine and a dear friend. Adam was sick and tired from JavaScript's brittleness, and about two years ago he started migrating our code base to TypeScript. But that wasn't enough for him. He kept complaining: "What good are my types, if some other service decides to send me bad data and breaks my code?". That's when he discovered Zod.
