Question 1

How do I use Coloor with React?

Accepted Answer

Since Coloor processes static HTML, you need to call the Coloor() function manually after the DOM updates in React components. The README mentions this for dynamically rendered HTML to ensure placeholders work correctly.

Question 2

Coloor vs lazy loading libraries: which should I use?

Accepted Answer

Coloor improves perceived performance by showing immediate placeholders, while lazy loading defers image loading until needed. They can be combined; use Coloor for above-the-fold images and lazy loading for off-screen content to optimize both speed and payload.

Question 3

Can I use Coloor without Webpack or Gulp?

Accepted Answer

Yes, you can use the core Coloor function in Node.js to process HTML strings directly, but for automated builds, the Gulp plugin or Webpack loader simplifies integration and streamlines workflow.

Question 4

What browsers support Coloor's placeholder effect?

Accepted Answer

Coloor relies on canvas for generating placeholders, so it works in browsers that support canvas. It gracefully falls back to standard loading in older browsers, ensuring basic functionality.

Question 5

How does Coloor affect page performance metrics?

Accepted Answer

Coloor enhances perceived loading speed by displaying placeholders quickly, but the base64 strings increase HTML size, potentially impacting First Contentful Paint. The tiny runtime minimizes JavaScript execution time.

Question 6

Does Coloor work with responsive images using srcset?

Accepted Answer

No, Coloor currently doesn't handle srcset attributes; it decorates only the src attribute of img tags. You'd need additional tools or manual adjustments for responsive image support.
