purescript-halogen/purescript-halogen v1.0.0

on GitHub

Many breaking changes since v0.12, including:

• Components now don't reveal their state in their type signatures. This has many knock on implications - a major one being a drastic simplification of types for parent components (no more Coproducts!)
• peek is gone in favour of a dedicated mechanism for raising / listening to messages
• Components can have "input values" now, that allow data to be passed down when a parent re-renders
• Rendering is more efficient, due to patching only taking place at the component level
• No more virtual-dom dependency required, by default a native PS virtual dom is used
• The HTML type that components render is now parameterised to potentially allow for non-HTML components (React Native, for example - although no driver is provided for this)
• The non-indexed HTML DSL is no longer provided
• EventSource subscriptions have been overhauled. Components can also choose to unsubscribe now, and will automatically unsubscribe when finalized.
• refs in the HTML no longer raise an event, but are accessed through the HalogenM DSL
• Component lifecycle handler ordering has been made predictable
