Think like a developer: Building Components Step-by-Step

Building a component gets easier when you follow a consistent process. Instead of trying to write the perfect version on the first try, you build in layers.

Step 1: Define the Output

Before writing any code, describe what the component should render. Sketch it if you have to. A card with a title, description, and a button. A nav with links. Be specific.

Step 2: Hardcode It First

Write the component with real data, no props, no logic:

function UserCard() {
  return (
    <div className="card">
      <h2>Jane Smith</h2>
      <p>Frontend developer based in Jakarta.</p>
      <button>View profile</button>
    </div>
  );
}

This gives you something to look at immediately and a working foundation to refactor from.

Step 3: Extract Props

Now replace the hardcoded values with props:

function UserCard({ name, bio }) {
  return (
    <div className="card">
      <h2>{name}</h2>
      <p>{bio}</p>
      <button>View profile</button>
    </div>
  );
}

Only extract what actually varies. If the button label is always “View profile”, leave it hardcoded.

Step 4: Handle Edge Cases

What if bio is empty? What if name is very long? Add the minimum defensive logic needed:

function UserCard({ name, bio = "No bio provided." }) {
  return (
    <div className="card">
      <h2>{name}</h2>
      <p>{bio}</p>
      <button>View profile</button>
    </div>
  );
}

Step 5: Refine

Now polish — styling, accessibility, animation. Doing this last keeps the earlier steps fast and focused.

The pattern: output → hardcode → extract → edge cases → refine. Each step is smaller and clearer than trying to do everything at once.
