mitt VS apexcharts.js

Mitt is a small (200 bytes) library that provides the same functionality. It doesn't have many updates, because it's simply perfect and there are not many things to improve there. It gets the job done. Don't be frightened, if in 2 years npm will say it's 2 years old. This library is just perfect with no bloatware. In the worst case, just copy-paste its code to your app.

The implementation can vary widely depending on the requirements. For our application, we will take a small library that will do almost everything for us:

You can use an event bus for this, looks like they removed this functionally from vue 3 so you'll need a 3rd party package like mitt

then we need to install an external library implementing the event emitter interface, in this case mitt

date-fns and mitt (event emitter) are also frequent helpers, but I'm considering dayjs and nanoevents for these cases.

Not sure I understood the post right, bit you may want to check Mitt. It's popular event emitter package that quite nicely deals with this very issue.

As suggested in official docs you could use mitt library to dispatch events across components.

You can use it mitt library. https://github.com/developit/mitt

For situations like this, I use simple event emitter / pubsub library called mitt. It's small and lightweight, however there are many similar libraries that would work.

In this article I want to show you how I have implemented this pattern in my Nuxt 3 applications using Mitt which already provides full TypeScript support. To fully understand what's happening under the hood I recommend to have a quick read of Mitt documentation before continue reading.

As a frontend dev who also works in UX and graphics from time to time, I find it helpful to be able to do both, looking at SVGs as both a vector graphics format and a human-readable XML. IME the workflow depends more on whether any SVG is meant to be illustrative (like art) or quantitative (like charts) or interactive and animated/mutable (like a game).

For something like this bell example (https://svg-tutorial.com/svg/bell), you can certainly hand-code it if you're really math-inclined and can estimate the formulas of curves just by looking at them, but for us mere mortals, it's easier to just draw out the curves in a graphics app then export as an SVG. And for things like the ringer (is that what you call it? the orange ball thing at the bottom of the bell that strikes the bell to make the sound), being able to visually draw it on a canvas, change its size, drag it around and play with its colors and dimensions, etc. is really helpful. Figma is fine for simpler graphics, but it's really more of a UX tool than a graphic design tool, and Illustrator is a lot more powerful. Inkscape is a FOSS option.

In other circumstances, though, manipulating the SVG XML directly is also very helpful. Let's say you want to programatically generate a bar chart. If you have a big dataset, it's going to take a designer forever to manually plot them and change them every time the data changes. But it's easy for a dev to use Javascript (or any language) to draw each rectangle, programmatically adjust their heights and colors based on the data, add tooltips, etc. And that way you can dynamically update them in real-time whenever the data changes (like if the user selects a different date range, or new events come in). A lot of this is made easier by libs like https://frappe.io/charts or https://apexcharts.com. But before you take that approach, you should know that for complex charts, sometimes Canvas rendering (or just generating graphics in the backend) can be more performant than SVG.

SVGs can also be animated and interactive, not just with CSS transitions but by directly manipulating the XML geometries, like http://snapsvg.io/demos/ or https://www.svgator.com/ or https://codepen.io/collection/XpwMLO/. This is fine for product pages and such, but for really graphics-intensive apps (full games) it's probably slower than other rendering pipelines. (Not my specialty, won't speculate too much.)

TLDR Drawing them in a graphics app is usually easier for the designers, but the XML can be programmatically manipulated afterward to great effect.

ApexCharts is a modern charting library that helps developers to create beautiful and interactive visualizations for web pages. It is an open-source project licensed under MIT and is free to use in commercial applications.

tradingview.com for the chart... but also apexcharts.com is a decent open source library whereas TV is not open source
