📦 Published PR as canary version: 1.0.16--canary.25.faaaa70.0

✨ Test out this PR locally via:

yarn add tonic-minijs@1.0.16--canary.25.faaaa70.0

Changes

  • Feature: Add MiniJS.reset() function.
    • This function clears all states, variables, and entities, and re-initializes MiniJS.

Usage

  document.addEventListener("turbo:load", function(e) {
    MiniJS.reset()
  })

This ensures that MiniJS is reset whenever a Turbo event is triggered, maintaining a fresh state.

Walkthrough

This update introduces substantial enhancements to multiple classes within the codebase, focusing on template handling in Entity, state reset in Mini, a dispose method in the State class, and event handling improvements in Events. It also updates the index.html to include additional attributes and functionality for user interactions.

Changes

Files/Paths Change Summaries
lib/entity.js Added template-related methods: isEachEl, setEachItemTemplate, and getEachItemTemplate to Entity.
lib/entity/attributes.js Replaced this.childClone assignment with a call to setEachItemTemplate and subsequent use of getEachItemTemplate().children.
lib/main.js Added reset method in Mini class and incorporated state reset logic on user navigation back.
lib/state.js Added a dispose method to reset properties and clear collections.
index.html Introduced new list item with selectable option and added :clickout attribute to a div element.
lib/entity/events.js Enhanced event listener handling and added a debounce method to throttle event callbacks.

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.

-    else if (attr === ':clickout') return this.setClickoutEvent()

This change cleans up the control flow and adheres to best practices by eliminating unnecessary else keywords after return statements.

This change simplifies the code by using this directly, leveraging the fact that arrow functions do not have their own this context.

1035-1035: Implement click-outside functionality with caution.

The :clickout directive is used to modify showSelect state when clicking outside of certain elements. This is a custom Vue directive and should be tested thoroughly to ensure it works across all browsers and doesn't interfere with other UI elements.

Ensure consistent ID attributes for list items.

The id="listbox-option-0" is repeated across multiple list items. This can lead to invalid HTML as id attributes must be unique within a page. Consider using a dynamic value or removing these IDs if they are not necessary.

- id="listbox-option-0"
+ id="listbox-option-{{ index }}"

Improve the implementation of applyEvent method by simplifying the debounce usage.

-    [].concat(listener).forEach(({ el, eventName, event }) => {
-      el.addEventListener(eventName, (e) => {
-        this.debounce(() => {
-          event(e)
-        }, 50)
-      })
-    })
+    listener.forEach(({ el, eventName, event }) => {
+      el.addEventListener(eventName, this.debounce(event, 50))
+    })

This change ensures that the event handler itself is debounced, rather than creating a new debounced function every time an event is triggered, which is more efficient and cleaner.

Refactor the debounce method to prevent multiple simultaneous timeouts.

-    if (this.timeout) return
-    clearTimeout(this.timeout)
+    clearTimeout(this.timeout);

This change ensures that any previous debounce timeouts are cleared before setting a new one, preventing multiple debounce operations from overlapping incorrectly.
