What We Did in Step 7 (Conclusion)

  1. We removed the background attribute from the CldImage component in ProductGrid.svelte to make it even more minimalistic.

What to demonstrate in Step 7

  • We have a clean minimalistic grid of products with a transparent background thanks to the Cloudinary AI superpowers.

What We Did in Step 6 (Background removal)

  1. We changed the crop to pad in ProductGrid.svelte.

  2. We removed the replaceColor effect from the earbuds image in +page.svelte.

  3. We removed the fillBackground={true} and replaced it with removeBackground={true}.

  4. We added background color to the CldImage component in ProductGrid.svelte:

    <CldImage background="white" ... />

What to demonstrate in Step 6

  • It nicely removed the backgrounds. We altered the eardbuds image with the replaceColor effect, but it wasn't perfect, removing the background looks much better.
  • We now have a nice unified set of product images.

What We Did in Step 5 (Overlays)

  1. We have added overlays configuration to two images in +page.svelte.

    • One green "New" label in the top right corner of the first image, rotated slightly.
        {
        src: 'https://res.cloudinary.com/dltsbx5b6/image/upload/v1701773752/w66suwxav7q7vmd5eqjc.jpg',
        title: 'Bright red purse with gold',
        overlays: [
            {
                text: {
                    text: 'New!',
                    fontSize: 18,
                    fontWeight: 'bold',
                    fontFamily: 'Montserrat',
                    color: 'white',
                    letterSpacing: 3
                },
                position: {
                    gravity: 'north_east',
                    y: 20,
                    x: 20,
                    angle: -18
                },
                effects: [
                    {
                        background: 'green',
                        crop: 'lpad',
                        radius: 'max',
                        width: 80,
                        height: 80
                    }
                ]
            }
        ]
    },
    • One orange "Sale" label in the top right corner, rotated a bit more:
            {
        src: 'https://res.cloudinary.com/dltsbx5b6/image/upload/v1701780641/red-bluetooth-earbuds_njubn2.jpg',
        title: 'Red bluetooth eardbuds',
        overlays: [
            {
                text: {
                    text: 'Sale!',
                    fontSize: 20,
                    fontWeight: 'bold',
                    fontFamily: 'Montserrat',
                    color: 'white',
                    letterSpacing: 3
                },
                position: {
                    gravity: 'north_east',
                    y: 20,
                    x: 20,
                    angle: 45
                },
                effects: [
                    {
                        background: 'orange',
                        crop: 'lpad',
                        radius: 'max',
                        width: 100,
                        height: 100
                    }
                ]
            }
        ],
        ...

  2. And we pass the overlays to the CldImage component in ProductGrid.svelte:

    <CldImage overlays="{image.overlays" ?? []} ... />

What to demonstrate in Step 5

  • We have labels just from configuration :)

What We Did in Step 4 (AI-driven image processing)

  1. We modified the ProductGrid.svelte CldImage properties to use:

    <CldImage fillBackground="{true}" ... />
    • It's a beta feature, but now we have a nice and even grid which shows the full products on their background.

  2. We also added some effects to the CldImage properties to enhance the images and make them look nicer and more consistent. We can find the list of available effects in the Svelte Cloudinary documentation. We used the following effects:

    <CldImage effects={[
            {
               autoContrast: true,
               vibrance: 10,
               improve: true,
            },
         ]} ... />

  3. Finally, we added an option to include effects per image in +page.svelte and modified the CldImage properties to include the individual effects as well:

    <CldImage effects={[
            {
               autoContrast: true,
               vibrance: 10,
               improve: true,
            },
            ...(image.effects ?? [])
         ]} ... />

  4. And added a color_replace effect to the earbuds image in +page.svelte, so the white-ish color is replaced with gray color matching the other backgrounds. The syntax for the "replaceColor" effect is replaceColor:<color_to_replace_with>:<tolerance>:<color_to_replace>.

          {
         src: 'https://res.cloudinary.com/dltsbx5b6/image/upload/v1701780641/red-bluetooth-earbuds_njubn2.jpg',
         title: 'Red bluetooth eardbuds',
         effects: [
            {
              rreplaceColor: 'CBCBCB:20:F7F5F8'
            }
         ]
      },

What to demonstrate in Step 4

  • Now it's a nice and even grid with all the products showing in full with their backgrounds.
  • We also used the autoContrast, vibrance and improve filters to enhance the images.
  • We also used the replaceColor filter to replace the white-ish color in the earbuds image with gray color matching the other backgrounds.

What We Did in Step 3 (Dynamic transformation)

  1. We modified the ProductGrid.svelte CldImage properties to use:

    <CldImage width="{500}" height="{500}" crop="limit" ... />
    • That means we have defined a square with max dimensions of 500x500px,
    • and we are resizing the images to display in this square.

    Other possible values for crop to play with are:

    • fill - fill the square with the image, cropping the image if necessary
    • fit - fit the image inside the square, adding whitespace if necessary
    • limit - fit the image inside the square, but don't upscale it
    • pad - fit the image inside the square, adding whitespace if necessary, but don't upscale it

    You can check the interactive demo to see how the different crop modes work.

What to demonstrate in Step 3

  • Now the grid is nice and even. We could also show how it looks like when we change limit to thumb.
  • Not all images show the full product though. We could change it to crop="pad", which shows the whole products, but it feels uneven.
    • We'll address it more nicely in step 4 using the AI enabled capabilities.

What We Did in Step 2 (Cloudinary with auto optimization)

  1. We manually uploaded our product images to Cloudinary using the Cloudinary Console.

  2. We changed the srcs in our images array in the +page.svelte route to point to the cloudinary URLs instead of the local files.

    • We got the URLs from the "Media Library" in the Cloudinary Console by clicking on the <> icon that copies the link to the image.

  3. We have added an env.local.example file. You'll need to copy this file, rename it to .env.local and replace [YOUR_CLOUDINARY_CLOUD_NAME] with the cloud_name value found in the Cloudinary Console surrounded by quotes (e.g. "abcdefghij").

  4. We modified the ProductGrid.svelte component to use the CldImage component from Svelte Cloudinary instead of a plain img tag. It requires us to specify width and height attributes, so we have set both to 600 and set the objectFit attribute to contain to maintain the aspect ratio of our images for now.

What to demonstrate in Step 2

  • The images served from Cloudinary are now optimized for the browser and the network. If you go to the Network tab in your browser's dev tools and set the throttling to "Slow 3G", you can demonstrate how they load now and, if you switch to the previous commit, how slow they would have loaded before.

What We Did in Step 1 (raw images)

  1. We added Tailwind to the project.

  2. We added a ProductGrid.svelte component which takes in an array of image srcs and titles and displays them in a Tailwind grid.

  3. We added the images array to the +page.svelte route and filled it with some stock photos we added to the static/product-images folder.

    Note: The /src/lib/routes/+page.svelte file is the file that is loaded in the browser when you navigate to the root of the app (/) by adding a subfolder such as /about with a new +page.svelte file, you would create a new route that would point to the /about URL.

  4. We added the ProductGrid component to the +page.svelte file and passed in the images array.

  5. We added a +layout.svelte file which is the layout for all the pages in the app and loads the Tailwind styles.

  6. We have installed the svelte-cloudinary package, so we can have it ready for the next step.

What to demonstrate in Step 1

The images are fairly big and they are high-res unoptimized JPGs. If you go to the Network tab in your browser's dev tools and set the throttling to "Slow 3G", you can demonstrate how slow they load.
