react-calendar VS apexcharts.js

3. React Calendar

I want to use a Calendar to schedule appointments for my final project. I was using https://www.npmjs.com/package/react-calendar However, I am unable to choose the hour when using this. I also have a hard time disabling the days when an appointment is already scheduled.

npm install react-calendar but I have no idea how to style it, or to give it some color. The instructions in react-calendar - npm do not provide any information about that. I was wondering if anyone that has used this package could help me here. This is the code I have:

You want this React-Calendar

That seems simple enough to do the MVP with vanilla JS (or jQuery if you really want), but if you go the React route you could leverage packages like React calendar or date pickers for booking that could make your life a lot easier. It’ll also be easier to scale once started since you’ll probably want to use some framework after your MVP is built anyway.

Now, here's the thing. I'm the maintainer of many popular React packages, React-PDF, React-Calendar, and React-Date-Picker just to name a few. Professionally, I maintain several large projects, which collectively have more than 30,000 Enzyme-based unit tests.

I was looking for a calendar to use in a React project and found the React-Calendar component. It has all the functionality that I was looking for and saves me a lot of time from building it out on my own. It can be controlled with state so that the selected date(s) can affect what displays in the app. I wanted to customize its styling to fit my project, so here's what I came up with!

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
