Lab 8: More Reusable Components

Objectives

• Create another reusable component
• Render the reusable component

---

Steps

Create another reusable component

1. Create the file src\projects\ProjectCard.js.

2. Implement a ProjectCard as a function (not class) component that meets the following specifications:

   1. Takes a project object as a prop.
   2. Cut the <div className="card">...</div> from the ProjectList component and use it as the JSX for the ProjectCard component.
   3. Add a function to format the description to 60 characters and call it when rendering the description.

   src\projects\ProjectCard.js

   import { Project } from './Project';

   import React from 'react';

   import PropTypes from 'prop-types';

   function formatDescription(description) {

   return description.substring(0, 60) + '...';

   }

   function ProjectCard(props) {

   const { project } = props;

   return (

   <div className="card">

   <img src={project.imageUrl} alt={project.name} />

   <section className="section dark">

   <h5 className="strong">

   <strong>{project.name}</strong>

   </h5>

   <p>{formatDescription(project.description)}</p>

   <p>Budget : {project.budget.toLocaleString()}</p>

   </section>

   </div>

   );

   }

   ProjectCard.propTypes = {

   project: PropTypes.instanceOf(Project).isRequired,

   };

   export default ProjectCard;

Render the reusable component

1. Open the file src\projects\ProjectList.js.

2. Render the ProjectCard component passing it the project as a prop.

   src\projects\ProjectList.js

   import React from 'react';

   import PropTypes from 'prop-types';

   import { Project } from './Project';

   + import ProjectCard from './ProjectCard';

   function ProjectList ({ projects }) {

   const items = projects.map(project => (

   <div key={project.id} className="cols-sm">

   - <div className="card">

   - <img src={project.imageUrl} alt={project.name} />

   - <section className="section dark">

   - <h5 className="strong">

   - <strong>{project.name}</strong>

   - </h5>

   - <p>{project.description}</p>

   - <p>Budget : {project.budget.toLocaleString()}</p>

   - </section>

   - </div>

   + <ProjectCard project={project}></ProjectCard>

   </div>

   ));

   return <div className="row">{items}</div>;

   }

   ProjectList.propTypes = {

   projects: PropTypes.arrayOf(PropTypes.instanceOf(Project)).isRequired

   };

   export default ProjectList;

3. Verify the project data displays correctly (it should still look the same as it did in the last lab except for the ... after the description) in the browser.
