Improvement: Add try-catch blocks for better error handling in social-share-button.js

[coderabbitai]

Overview

This issue tracks the addition of try-catch blocks in src/social-share-button.js to improve error handling and resilience. Adding defensive error handling in key methods ensures that unexpected failures are caught and surfaced appropriately, rather than silently failing or causing unhandled exceptions.

---

Try-catch blocks to add

1. createButton() → document.querySelector()

querySelector() throws a SyntaxError when passed an invalid CSS selector string. Since the selector is user-supplied via options.container, a try-catch here is appropriate defensive programming.

2. fallbackCopy() → rename _err → error and add logging

The existing catch block silently swallows errors. Binding the error variable and logging it through the debug-gated _debugWarn() helper is a valid improvement.

---

Acceptance Criteria

• Add try-catch in createButton() around document.querySelector() with _debugWarn logging
• Update the fallbackCopy() catch block to bind the error variable and log it via _debugWarn()

@CodeRabbit change the title and body of this issue, remove the pr link and statement. Make it in general statement about adding catch and try for better error handling. Remove not necessary section from body and log violation part. Change acceptance criteria accordingly

## Overview

This issue tracks the addition of try-catch blocks in `src/social-share-button.js` to improve error handling and resilience. Adding defensive error handling in key methods ensures that unexpected failures are caught and surfaced appropriately via the project's debug logging utilities, rather than silently failing or causing unhandled exceptions.

## Try-catch blocks to add

### 1. `createButton()` → `document.querySelector()`
`querySelector()` throws a `SyntaxError` when passed an invalid CSS selector string. Since the selector is user-supplied via `options.container`, a try-catch here is appropriate defensive programming.

### 2. `fallbackCopy()` → rename `_err` → `error` and add logging
The existing catch block silently swallows errors. Binding the error variable and logging it through the debug-gated `_debugWarn()` helper is a valid improvement.

## Acceptance Criteria

- [ ] Add try-catch in `createButton()` around `document.querySelector()` with `_debugWarn` logging

Learning: In AOSSIE-Org/SocialShareButton (src/social-share-button.js), the empty catch blocks in `_emit()` around DOM CustomEvent dispatch, onAnalytics callback, and analyticsPlugins loop should be replaced with debug-conditional console.warn calls (e.g., `if (this.options.debug) { console.warn("[SocialShareButton Analytics] ...", err); }`). Analytics failures must remain non-fatal (never block the core share action), but empty catch blocks are considered too weak as they hide integration bugs and make debugging harder. A plain comment inside the catch is not sufficient — a conditional warning is preferred.

Learning: In AOSSIE-Org/SocialShareButton, kpj2006 confirmed that bare console statements in library catch blocks are unacceptable in production because they pollute end-user browser consoles and can leak internal error details. The approved pattern is a debug-gated `_debugWarn(message, err)` private helper (single `eslint-disable-next-line no-console` comment inside it), called from catch blocks in `_emit()`. When `options.debug` is false (the production default), nothing is ever logged. Passing the `err` object to `_debugWarn` is explicitly safe under this pattern.

Learning: In src/social-share-button.js, the ESLint config (eslint.config.js) already enforces "no-console": "error" (issue `#44` is closed). The existing debug console.log in _emit() uses an `// eslint-disable-next-line no-console` directive. For the catch blocks in _emit(), the recommended pattern is a private `_debugWarn(message, err)` helper method with a single eslint-disable-next-line comment, rather than adding inline console.warn calls with per-site eslint-disable comments. This keeps no-console violations contained to one location.

Learning: For the AOSSIE-Org/SocialShareButton repository, kpj2006 wants contributors to add proper inline comments to all methods in library source files (especially src/social-share-button.js). The preferred enforcement mechanism is CodeRabbit path-based review instructions (skills) in .coderabbit.yaml rather than scripts or workflows. Flag any newly added or modified function that lacks a descriptive comment during reviews.
