Introducing Gradient King - Never again run out of gradients! 🌈

Hello Geeks πŸ‘‹

This is Savio here. I'm young dev with an intention to enhance as a successful web developer. I love building web apps with React. I have proved my superiority in frontend technologies. Due to exams, I wasn't able to attend the last hackathon powered by vercel, but now I'm super excited to share my biggest ever project made as a submission for Amplify Hashnode Hackathon

Little flashback

I constantly need gradients for my projects, yeah, every developer needs them. Gradients are very much important as they give good UX to the users. So, I started planning an app on it and it then enlarged to grab awesome features. The project is never finished, it is still becoming better and better. I'm glad I have created useful stuff for the dev community.

Introducing Gradient King

Gradient king solves all your gradient problems. It provides a huge collection of gradients and you could easily choose one. Besides It, we also provide a well-efficient gradient generator where you could upload your image and grab the gradients from it. How cool is that πŸ™Œ

Github Repo / Live Demo



I was struck by these 2 awesome articles The logic of good gradients and The Secret of Great Gradient

Have you ever noticed how some colors and gradients look so natural and beautiful, while others look so unnatural and weird? The reason for this can be found somewhere between our pupil and our visual cortex. The difference between natural and unnatural is just familiarity or maybe nature is created to perfectly to fit together with our souls. The gradients we identify as beautiful are similar to what we see in nature. Conversely, a combination of colors our eyes have never seen before would rightly evoke feelings of discomfort and unease.

And this is what gave me the idea to build an awesome gradient generator where you could upload your local images πŸ“‚ and get them converted into gradients 🎨

This was the first idea 🎯 in my mind and then I got to make the app more advanced with more features


Please watch the short demo (use headphones 🎧)


So far, these are the features Gradient King have

  • 100+ gradients

    Gradient King is richly supplied with gradients for you to copy. As this is an open-source project, the list will increase for sure. πŸ‘ You're getting access to a huge amount of gradients and simply clicking on the Copy CSS button copies the CSS code of that gradient to your clipboard πŸ“‹

  • Generate your own gradients
    Untitled design (2).gif
    Gradient King provides you a playground where you create gradients from your local images. πŸ“‚

    Indeed Mother Nature is rich in colors, So why should we waste this opportunity?

  • Search
    Gradient King is now able handle search for anything on the page - Colors, authors, contributors, etc πŸ”

  • Seperate page for each gradient
    Untitled design (6).png
    Gradient in a small part of a page may not be useful for you as you have to use in big area. No problem, just click on a gradient and it will open in a relatively larger area πŸ’ͺ

  • PWA, Installable app (5).png
    Yeah, it was a task but I accomplished it. I managed to get passed on all the Progressive Web App checks. Now, you're able to install the app on your local device and works offline πŸ’»

  • Contributor page
    Untitled design (7).png
    Are you an open-source enthusiast, this is for you. We proudly show our contributors on our main website and we love to ❀️ Go ahead and give a pull request, get featured on our contributor's page πŸ‘¨β€πŸ’»

  • Dark mode (4).png
    Dark mode πŸŒ’, an awesome feature everyone loves and cares about. Of course, I found time to work on it and make it happen. The dark mode is acceptable for all pages.

  • Fully Responsive
    Untitled design (10).png
    Responsiveness is an important part of a website πŸ“±, it doesn't matter why it should be, it just thinks you should do it. Yeah, I did get the same feeling.

    I know developers are not gonna code on their smartphones but as a web developer, it is my responsibility to add responsiveness to my project.

  • Free and Open Source
    I'm an open-source lover, I love to be πŸ’–. So, inviting all devs to view the code as well as contribute to the app.

  • Minimal UI, Lightning Fast, Elegant animations
    Untitled design (3).gif
    Thanks to Material UI, React Router Dom, Animate on Scroll and Animate.css. These awesome libraries helped me to add these awesome UX features. I super sure that they did a great job in the UX of my app ⚑️.

    Everything loads super fast (without even loading), So appropriate to use on daily basis.

Gradient King is super productive enough to grab the best gradients for your next app ✨️

πŸ’» Built with

Planning, Building, and Deploying

Oh yeah, it was time-consuming, but I enjoyed it.

  • Designing I used Figma for my design, I'm not an expert but I know how to do basic designing and prototyping.
  • Planning Notion is an awesome tool to be cared for. It is super productive enough for me to plan my daily work. I used Pomodoro timers too, I want to be productive.
  • Time to code I'm a true React lover. I use it for all my projects and I did use it for creating Gradient King
npx create-react-app gradientking
Enter fullscreen mode Exit fullscreen mode

And it is how it started, coding components, designing it, getting errors, copying code from StackOverflow, debugging, and Of course, it continues...
I wanted my app to get the data from a JSON file. So, I used useEffect to make everything work. Like this πŸ‘‡

const [data, setData] = useState([]);
const getData = () => {
    fetch("data.json", {
      headers: {
        "Content-Type": "application/json",
        Accept: "application/json",
      .then(function (response) {
        return response.json();
      .then(function (data) {

  useEffect(() => {
  }, []);
Enter fullscreen mode Exit fullscreen mode

And I'll the respose as an array so that I could map it or pass it to other pages.
Screenshot 2021-02-26 15:44:55.png
And the next thing was that to implement Dark Mode πŸŒ’. I created a component useLocalStorage.js, I did it to avoid duplication of the same code. Now everything becomes fast and easy, we can now use localstorage like this πŸ‘‡

const [dark, setDark] = useLocalStorage("DarkMode:", true);
Enter fullscreen mode Exit fullscreen mode

And now, we're able to store our data in localstorage
Now, I made a code that if dark mode is true and dark class and else dark mode is false keep it same. So, we just have to change some of our CSS like this πŸ‘‡

.dark .App {
  background: #333;
Enter fullscreen mode Exit fullscreen mode

And that's it. Now, we have dark mode in our app. Next, to make the app responsive, I used @media queries. Like this πŸ‘‡

@media (max-width: 500px) {
    .preview {
       width: 90%;
       height: 70%;
Enter fullscreen mode Exit fullscreen mode

To handle the search, it was easy coding just need a bit of logic. There is an inbuilt function called find() and it helps 🀝.

const findSearchWord = (e) => {
    if (e.keyCode === 13) {
Enter fullscreen mode Exit fullscreen mode

and then we should render our component.

      placeholder="Search for a Color or Author"
      onKeyDown={(e) => findSearchWord(e)}
Enter fullscreen mode Exit fullscreen mode

And yeah, the total build process is far longer, I just told you the main part of it. Head over to Github Code and find more. After the basic completion of the code, I pushed it to Github and then whenever I need to add more stuff I did a new commit.

  • Deployment Honestly, I'm super new to Amplify. I watched a lot of youtube videos in fact did some tutorial to get started with Amplify. My friend helped me lot, he guided me to use Amplify and helped me in hosting the app πŸ‘ Amplify is super powerful, it has a much larger space. I was new to Amplify so I wasn't not knowing how to use these, but I'm sure I'm gonna learn more on AWS. It is yet to be explored for me 🌊 > Feel free to use Gradient King:


Challenge Solution
adding scroll animations Used AOS library
User want to contribute an Idea Made a feature request template
Change different URLs without loading Used react-router-dom
Generate image by uploading faster Converted it into base64 value
user want to see the gradient in a bigger way Implemented a page where it show the clicked gradient
Notification withing the app Used react-toastify library
User want to report a bug Made bug template
Make the app 100/100 on PWA Check Optimised app, solved errors
Responsiveness of the app Used @media queries
Stop duplication of same user details in contributors page Wrote a jquery code to solve it

✨️ What's next

I'm pretty sure that I will be constantly adding more and more extraordinary features as I consider this as my biggest project to date. These all are the things I have planned to do in the next few days
