Question 1

How do I integrate Alpine.js with PhxComponentHelpers in LiveView?

Accepted Answer

Use set_prefixed_attributes with prefixes like @click or x-bind: in your components to bind Alpine.js behaviors. The README shows examples for handling dynamic attributes seamlessly from templates.

Question 2

PhxComponentHelpers vs Surface: which should I use for component libraries?

Accepted Answer

PhxComponentHelpers is lightweight and stays close to raw LiveView, ideal for custom libraries with minimal overhead. Surface is a full framework with more features but a steeper learning curve; choose based on need for simplicity versus comprehensive tooling.

Question 3

Can I use PhxComponentHelpers without Tailwind CSS?

Accepted Answer

Yes, but features like extend_class for CSS merging are optimized for Tailwind. You can still use attribute helpers, but some conveniences may be lost if not using Tailwind, as noted in the PETAL stack focus.

Question 4

How to handle form validation with PhxComponentHelpers?

Accepted Answer

Leverage the form helpers like set_form_attributes to integrate with Phoenix.HTML.Form, allowing easy access to form data, validation errors, and field values in your custom components, as illustrated in the form examples.

Question 5

Is PhxComponentHelpers good for large applications?

Accepted Answer

It scales well by reducing boilerplate, but since it doesn't provide pre-built components, large teams might need to invest in building and maintaining a custom library, which can increase initial development time.

Question 6

How do I override CSS classes from templates using PhxComponentHelpers?

Accepted Answer

Use the extend_class helper in components, and in templates, pass class attributes with overrides using syntax like '!p-* p-0'. The library merges classes intelligently, allowing specific overrides as shown in the button example.
