A responsive frontend crowdfunding projects page, where the users can select the project they want to support and therefore submit a pledge and check the project's data status (the goal, total money backed, total number of backers, progress bar).
This web application went through Unit and Integration tests with Testing Library, and End-To-End tests with Cypress.

Users should be able to:
- View the optimal layout depending on their device's screen size
- See hover states for interactive elements
- Make a selection of which pledge to make
- See an updated progress bar and total money raised based on their pledge total after confirming a pledge
- See the number of total backers increment by one after confirming a pledge
- Toggle whether or not the product is bookmarked
This section should list any major frameworks that you built your project using. Leave any add-ons/plugins for the acknowledgements section. Here are a few examples.
- React
- create-react-app
- Sass
- React-Bootstrap
- Testing Library
- Cypress
- Firebase
- Netlify
- Flexbox
- CSS Modules
- Using component composition to avoid prop drilling in React. It is possible to compose components by making one a child of another.
<PledgesModalCard
showModal={showModal}
onHide={handleCloseModal}
modalIntroduction={modalIntroduction}
pledgeSubmitted={pledgeSubmitted}
confirmationPledgeText={confirmationPledgeText}
>
<PledgeList
pledges={allPledges}
selectedPledge={selectedPledge}
onPledgeSelect={handlePledgeSelect}
onSubmit={handleSubmit}
onPledgeConfirmClick={handlePledgeConfirmClick}
/>
</PledgesModalCard>
PledgeList is invoked inside of PledgesModalCard and hence it is a child of it. Every component has an automatic prop name children that holds the children of the component. Therefore, in PledgesModalCard we can write:
export const PledgesModalCard = ({children}) => {
return (
<Modal>
(...)
{children}
</Modal>
);
};
Finally, we can access the PledgeList props that were passed from the PledgesModalCard component:
export const PledgeList = ({
pledges,
selectedPledge,
onPledgeSelect,
onSubmit,
onPledgeConfirmClick,
}) => {
return (
(...)
);
});
- Import SVGs as React Components
import { ReactComponent as BookmarkIcon } from "../../icons/icon-bookmark.svg";
export const ProjectHeader = ({ title, description, onClick }) => {
(...)
return (
<BookmarkIcon />
)
The ReactComponent import name is significant and tells Create React App that you want a React component that renders a SVG, rather than its filename.
- Child component updating Parent state
In the parent component, declare a state and define a function to update the state. Pass that function down as props to the child component
const Project = ({ pledges, project }) => {
const [allPledges, setAllPledges] = useState(pledges);
const [projectStatus, setProjectStatus] = useState({
moneyBacked: project.moneyBacked,
totalBackers: project.totalBackers,
});
const handleStockUpdate = (pledgeId) => {
setAllPledges((...));
};
const handleProjectStatus = (pledgedAmount) => {
setProjectStatus((...));
};
const handlePledgeConfirmClick = (pledgeId, pledgedAmount) => {
handleProjectStatus(pledgedAmount);
handleStockUpdate(pledgeId);
};
return(
(...)
<PledgeList
onPledgeConfirmClick={handlePledgeConfirmClick}
/>
)
}
Between the parent component and the component where the function will be invoked there is a middle component that will work as a bridge to accept and pass props through to the child component.
export const PledgeList = ({
onPledgeConfirmClick,
}) => {
return (
<Pledge
onContinueButtonClick={onPledgeConfirmClick}
/>
)
in the Child component, we define a button with an onClick event and invoke the function passed as props with the correspondent arguments:
export const Pledge = ({ onContinueButtonClick }) => {
return (
<button onClick={() => onContinueButtonClick(id, amountInputRef.current.value)} >
Continue
</button>
)
}
- Storing values with the useRef hook
As the name suggests,useRefcan store a reference to a DOM element. To do this, I create the ref, and then I pass it into the element:
export const Pledge = ({ minimumAmount, id, onContinueButtonClick }) => {
const amountInputRef = useRef();
return(
<input
type="text"
ref={amountInputRef}
name="pledgeAmount"
/>
)
}
This way I can access the value of the input element by using the methods .current and .value like so amountInputRef.current.value).
The key difference between useState and useRef is that:
- If you update the state, your component will re-render;
- If you update the value stored in your ref, nothing will happen.
This is an example of how you may give instructions on setting up your project locally. To get a local copy up and running follow these simple example steps.
You need to install the following elements:
- npm
npm install npm@latest -g- yarn
npm install yarn -g- Get a free JSON API at https://opentdb.com/api_config.php. Use of this API does not require an API Key.
- Clone the repo
git clone [email protected]:Francisco-Webdeveloper/sports-quiz.git- Install NPM packages
yarn installThis project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
