Assessment: Photo Wall

For this assessment, you'll be creating a photo wall:

Note that the above gif also demonstrates bonus features that are not part of the initial acceptance criteria.

In doing so, you'll be demonstrating a basic understanding of the following:

• maintaining state in components
• making API calls from within a React component
• Choosing the correct life cycle method for asynchronous method call
• iterating over state to dynamically generate DOM elements

Getting Started

Fork and clone this repository: https://gitlab.com/kenzie-academy/se/fe/react/assessment---react-photo-wall

Next, you'll need to install dependencies.

Before coding, you should ensure that this scaffold works by running the application:

npm start

Acceptance Criteria

The acceptance criteria are all laid out in src/App.jsx in comments. We've also reproduced them below:

Step 1: Declare state

The state object should include an array of photos, which will be iterated over later and displayed to the user in a grid.

Step 2: Declare a life cycle method

This life cycle method should:

• be called after the component is initially rendered
• fetch an array of photos
• add that array of photos to state once received

Step 3: Ensure valid images are rendered

The generated images should include:

• a photo's filename
• a photo's id
• a photo's URL

Where "photo" is the current photo in the array of photos being iterated over.

Step 4: Styling

Modify src/App.css to include styling that accomplishes the following:

• cause the header and .collage div to be centered on the page
• ensure that no more than 4 photos appear in a row

Bonus

If you find yourself with extra time (e.g., don't have other assessments to catch up on), you may consider improving the quality in a number of ways:

• You may have noticed that in the gif, the header remains at the top of the page while photos are being scrolled. Add styles to accomplish this in your version.
• See if you can find a way to limit the number of photos that get appended to say, 10
• Having done the above, see if you can add a button that, when clicked, will append the next 10 photos (that is, increases the limit from 10 to 20, 30, 40, etc). You'll need to look ahead to the documentation on event handlers and add another piece of state to your component in order to accomplish this.

Submission

You must submit a deployed application url. If you instead submit a link to a repository (that is, only code), you will not receive any points.
