Walkthrough

The changes enhance the Avatar.svelte component by adding support for a fallback image when the primary image fails to load. Two new properties, fallbackSrc and onError, are introduced to manage this functionality. Additionally, the documentation in avatar.md has been updated to reflect these changes, including minor formatting adjustments and a new section on the customizable placeholder feature. These modifications improve the component's usability and clarity without altering its existing logic.

Poem

In the meadow where avatars play,
A fallback image brightens the day.
When the main one fails, don’t you fret,
A custom placeholder, your best bet!
So hop along, let worries cease,
With smooth transitions, find your peace! 🐇✨

src/lib/avatar/Avatar.svelte (6)

6-7: LGTM!

The new exported properties fallbackSrc and onError are correctly typed, have appropriate default values, and include clear comments explaining their purpose. These changes align with the PR objective of adding support for a fallback image.

28-35: LGTM!

The updates to the avatarClass reactive variable correctly integrate the new props using the twMerge function. The changes maintain the existing logic while incorporating the new functionality seamlessly.

37-38: LGTM!

The introduction of the imageSrc reactive variable is a good design choice. It provides a single source of truth for the image source, making it easier to manage the fallback mechanism and maintain a cleaner separation of concerns.

40-45: LGTM!

The handleError function correctly implements the fallback mechanism by setting imageSrc to fallbackSrc when an error occurs and onError is true. The function signature is correctly typed, ensuring type safety. This change aligns with the PR objective of providing a smoother user experience when the primary image fails to load.

50-56: LGTM!

The changes to the img element correctly integrate the fallback mechanism into the rendering flow. Using imageSrc instead of src ensures that the fallback image is displayed when necessary, and binding the on:error event to handleError triggers the fallback mechanism when an error occurs. These changes align with the PR objective of providing a smoother user experience.

70-76: LGTM!

The changes to the img element in the else block correctly integrate the fallback mechanism into the rendering flow. Using imageSrc instead of src ensures that the fallback image is displayed when necessary, and binding the on:error event to handleError triggers the fallback mechanism when an error occurs. These changes maintain consistency with the previous img element and align with the PR objective.

src/routes/docs/components/avatar.md (4)

12-15: LGTM!

The addition of semicolons for consistency is a good practice and improves code readability.

47-47: LGTM!

The text refinement improves clarity and readability.

104-104: LGTM!

The text refinement improves clarity and readability.

Line range hint 185-223: Excellent addition of the Customizable Placeholder feature!

The new section provides clear instructions on how to use the fallbackSrc prop to specify a custom placeholder image. The example code demonstrates the usage correctly.

This feature enhances the usability of the Avatar component by allowing developers to provide a fallback image when the main avatar image fails to load.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>.
- Generate unit testing code for this file.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai generate unit testing code for this file.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai generate interesting stats about this repository and render them as a table.
- @coderabbitai show all the console.log statements in this repository.
- @coderabbitai read src/utils.ts and generate unit testing code.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Hi @shinokada,

Thanks for the suggestion!

In the current implementation, the component already manages the case where the default SVG avatar is used if fallbackSrc isn’t provided or src fails to load. Here’s how it works:

If src loads successfully: The image is displayed.
If src fails and fallbackSrc is provided (with onError set to true): The fallbackSrc image is used.
If fallbackSrc is missing or set to null: The default SVG avatar is displayed.

This gives users the flexibility to either specify a custom fallback or rely on the default SVG.

Relevant code:

Let me know if this works or if you have any other suggestions!

shinokada · 2024-09-22T15:18:37Z

If a user adds a wrong image path, the image won't be displayed.
Am I missing something here?

<Avatar src="/wrong/path/to/image.webp" fallbackSrc="/images/fallback-picture.webp" />

shinokada · 2024-09-22T15:22:07Z

Also why when a user add a fallbackSrc, it won't be displayed?

<Avatar src="/images/profile-picture-3.webp" fallbackSrc="/images/fallback-picture.webp" />
<Avatar fallbackSrc="/images/profile-picture-3.webp" />
<Avatar src="/wrong/path/to/image.webp" fallbackSrc="/images/profile-picture-3.webp" />
