UI Components website Released!

Hello guys,

I have developed an website which we can click a ui component and copy the scss code.

There are not many components, but I will add more gradually.


  • Click on the displayed component to see the internal code.
  • Code can be copied at the touch of a button.

Since the modal is supposed to open when the element is clicked, I used stopPropagation to adjust the input so that the parent element does not open when the child element is clicked.

I will add more components and more categories, such as Forms.
If you have any requests, don't hesitate to ask me! Any comments and requests are really welcome.

The reason I developed this website

Because I've always wanted this. I often write animations for my work, but I can't completely remember them no matter how many times I write them, and even outside of animation, I have to google how to write good shadows, underline, text-decoration and so on.
So, I thought it would be nice if I could save some time.


It would be too long to write the whole thing, so I'll just give you a rough idea of the structure.

I used react and typescript.

 ├ components/
 │ └ button/
 │ └ common/
 │ └ input/
 │ └ loader/
 ├ hooks/
 ├ models/
 ├ pages/
 ├ styles/
 │ └ styles.scss
 │ └ components/
 │     └ button/
 │     └ common/
 │     └ input/
 │     └ loader/
 └ App.tsx
Enter fullscreen mode Exit fullscreen mode

The code display part is placed under components/.
Under hooks/ I create Custom Hooks for a function to open/close modal.
Every type/interface/schema is under models/.
Then I places scss files under styles/.

How to develop the code display part


For example, I created button1.ts as follows.

// button1.ts
import { styleModel } from "models/styleModel";

export const button1: styleModel = {
  title: "button1",
  scss: `.button1 {
  position: relative;
  border-radius: 20px;
  margin: 65px auto;
  width: 150px;
  padding: 1rem 0;
  font-size: 1.5rem;
  background: #333c5f;
  color: #fff;
  font-weight: bold;
  -webkit-box-shadow: 0 5px 0 #576199;
  box-shadow: 0 5px 0 #576199;
  &:hover {
    -webkit-transform: translate(0, 3px);
    transform: translate(0, 3px);
    -webkit-box-shadow: 0 2px 0 #576199;
    box-shadow: 0 2px 0 #576199;
} as const;
Enter fullscreen mode Exit fullscreen mode

Then I added index.ts in button folder.

// index.ts
import { button1 } from "components/button/button1";
import { button2 } from "components/button/button2";
import { button3 } from "components/button/button3";
import { button4 } from "components/button/button4";
import { styleModel } from "models/styleModel";

export const buttons: styleModel[] = [button1, button2, button3, button4];
Enter fullscreen mode Exit fullscreen mode

Use map and show each button.
I would like to know if there is a more efficient way to do this.

Set up syntax highlighting

In oder to display the code, I definitely wanted to introduce syntax highlighting, so I looked for a library looked nice.

highlight.js looks good and lightweight.

yarn add highlight.js @types/highlight.js
Enter fullscreen mode Exit fullscreen mode
import hljs from "highlight.js";
import "highlight.js/styles/atom-one-dark.css";
// The highlight is about scss, so import the following
import scss from "highlight.js/lib/languages/scss";
// Give "scss" as a class name to the code tag inside the pre tag
hljs.registerLanguage("scss", scss);

const CodeBlock = ({ style }: Props) => {
// Highlight this component when this DOM is created.
  useEffect(() => {

  return (
    <div className="code-block-container">
      <div className={style.title}></div>
      {isOpen && (
        <Modal closeModal={clickHandler} copyText={copyText}>
          <code>&lt;div class="{style.title}"&gt;&lt;/div&gt;</code>
            <code className="scss">{style.scss}</code>
Enter fullscreen mode Exit fullscreen mode

Use <pre><code></code></pre> to add syntax highlighting.
I didn't want to add syntax highlighting for the div tag elements, so I just used <code> tags.

<code>&lt;div class="{style.title}"&gt;&lt;/div&gt;</code>
Enter fullscreen mode Exit fullscreen mode

There are dark mode and light mode for syntax highlighting.
I wanted to display in dark mode this time, so I used atom-one-dark mode.

If possible, I wanted to apply light mode to the div tag elements and dark mode to the scss parts to make it more understandable, but I found it difficult.
I tried to apply light mode in another file and imported it, but it was all overwritten by dark mode, so I gave up.

If you have any idea, please let me know.

Thank you for reading!
I would be really grad if you use this website and give me any feedback!
