Introduces htmx.parseJSON() method with optional relaxed syntax that accepts
unquoted object keys and auto-wraps bare properties in braces, making inline
attribute configurations significantly more readable.
Features:
- Unquoted keys: {timeout: 5000} instead of {"timeout": 5000}
- Auto-wrapping: timeout: 5000 instead of {timeout: 5000}
- Works in hx-config attributes, meta tags, and data-* attributes (useful for hx-live state)
- Global config.relaxedJSON option (defaults to true)
- Fully backwards compatible with strict JSON
- 3-line regex-based implementation using JSON.parse (no eval)
Examples:
<button hx-config='timeout: 5000, cache: "no-cache"'>
<meta name="htmx:config" content='defaultSwap: "innerHTML", timeout: 30000'>
Users can disable globally with config.relaxedJSON = false for strict JSON-only mode.
