leptos-rs/leptos v0.9.0-rc1

on GitHub

This release candidate for 0.9.0. 0.9 should be mostly compatible with most user application code. i.e., the migration path should be to upgrade from 0.8 to 0.9 and, in most cases, not need to make any changes. However, note the following changes

• All server functions now honor the server's request body-size limit, including multipart form data used for uploading files. If you have a server function that uses multipart data to upload files, you should ensure that you have this set to a reasonable limit for your use case (i.e., Axum defaults to 2 megabytes; if you need to support larger file uploads you will need to configure that). In Axum, for example, that can de done globally with a default body limit layer or with middleware on a server function.
• lazy feature: Lazy-loading/code-splitting is now gated behind a lazy flag on the leptos crate. This saves binary size for anyone who's not using lazy-loading; if you are, just enable the feature.
• serde_qs 1.0: we've migrated to the 1.0 series of releases for our default server-function input encoding (form URL data). This should reduce the requirement for #[server(default)] and similar workarounds for empty collections.
• on:toggle is now typed as a ToggleEvent rather than plain Event
• Function-call syntax for signal reads is now supported on stable (i.e., let (foo, set_foo) = signal(42); set_foo(13); foo() should work on both stable and nightly)
• Some of the trait implementations around signals have changed: in the worst case, if you have a component or function that takes impl Fn() -> T and you pass it a Signal<T> you may need to dereference it (foo=*signal rather than foo=signal). Let us know if there are any more noticeable breakages here. There are some awkward tradeoffs with inference and #[prop(into)] and in some cases we've had to make the choice we think will be best for the most use cases. Let me know if there are things that seem obviously wrong or unhelpful.
• A wide variety of semver-breaking changes that probably won't affect user code.
