v0.7.0-preview2 Latest
Latest

The -preview here is intended to convey: Here is a mostly-working but pre-alpha release of what I've been working on for the last six months or so. This work can be found in the leptos-0.7 branch. Enough work has been done that many (but not all) of the examples in the repo are functioning. This release is a fairly complete rewrite of the internals of the entire framework. You should expect both missing APIs and bugs.

Note the following:

  • You probably cannot just drop 0.7.0-preview2 to the Cargo.toml of an existing app and expect it to work
  • Imports have moved around a bit, to help improve discoverability, including moving from use leptos::*; to use leptos::prelude::*; and then using modules and reexports more sanely from the main crate
  • I've created a 0.7.0-preview playground that includes the setup of a basic app with comments. You should be able to expand from there.
  • There are lots of missing docs. These are easier to fill in going forward than to keep up to date during really active development.

Examples that Work

The following examples in the repo are known to work and can be useful to learn from

Notable Changes

  • I'm trying to avoid using features to change behavior as much as possible; see examples for Cargo.toml setup
  • use leptos::prelude::* instead of use leptos::*
  • Reactive system is now Send/Sync. In general for values being stored in signals this means you need to use Arc on occasion instead of Rc, etc.
    • For browser-only types stored inside signals I've tended to use the send_wrapper crate. Better ergonomics here are an open question
  • The renderer and IntoView trait work quite differently from before. In general, for type-erased views (.into_view() previously) you can use .into_any() or the Either:: types. Storing a View in a signal, cloning it, etc. are not viable approaches any more: store data in signals and rendering views, rather than storing views in signals.
  • There are Arc equivalents to each signal type (ArcRwSignal, ArcMemo, etc.) which manage their lifecycle via reference counting rather than the reactive ownership graph. This can be used for things like iterating over nested signals (see counters example) and pushing signals "up" in the tree, rather than using the manual .dispose() and owner manipulation patterns
  • Continuing to move names toward more typical Rust naming patterns (RwSignal::new(), signal() instead of create_signal() to match channel(), etc.)
  • Suspense now uses actual async -- see examples
  • The router uses a more statically-typed/compile-time route segment matching pattern. I have plans for a path!() macro to parse the old strings into this format but it's not implemented.
  • Route matching is now "first match wins," rather than using a scoring algorithm. I think this should work similarly to server-side route matching, but is not exactly how the old system worked.

Known Missing APIs

  • Actix integration (the playground uses Axum)
  • on: on components (e82227a)
  • spreading attributes onto components (e82227a)
  • MaybeSignal
  • Signal::with()
  • cargo-leptos hot reloading
  • anything animated (AnimatedShow, AnimatedRoutes, AnimatedOutlet)
  • Portals
  • slots
  • islands?
  • ... will add more here

Steps before -alpha

  • Migrate remaining examples
  • Missing features (above)
  • Update docs
  • Update tests
  • Add a !Send/!Sync thread-local arena for browser-type signals

What's Helpful?

Try things out, see what breaks, see what feels good. How can we improve the module imports? What are pain points? etc. Feel free to comment here or on Discord in the #preview channel,

v0.6.11

The primary purpose of this release is that it includes a fix for an unfortunate memory leak when using leptos_router on the server.

Also included are

  • the ability to spread both attributes and event handlers onto an element (see the new spread example for the full set of possibilities)
  • implementing IntoView directly for Rc<str>
  • massive improvements to the spans for error reporting in the view macro
  • migrating all our examples to use the stable features/syntax by default, to reduce confusion for new users

It's important to me to say that all three of the new features above were implemented by community members. This release brings us to over 250 total contributors over time, not to mention everyone who's done work on docs, templates, or libraries that exist outside this repo. Thank you to everyone who's been involved in this project so far.

v0.6.10

Mostly a patch release with a number of bugfixes, as well as some nice quality-of-life improvements:

  • allowing #[prop(attrs)] on slots
  • add support for on: to dynamic children of components (i.e., when you do <MyComponent on:.../>, the event listener is now applied correctly to more of the children of <MyComponent/>)

v0.6.8

Mostly this release is to disable file hashing by default, and streamline it's use. It can now be enabled by setting hash-files=true in your Cargo.toml or setting the LEPTOS_HASH_FILES=true env var when running cargo-leptos. If you're using Docker or moving the bin to a new folder, you need to copy the (by default) hash.txt file from target/{release_profile_name} to the same folder as your binary, and make sure the env var or cargo.toml option is enabled. Also some minor bug fixes

0.6.7

Hello everyone! Some lovely changes in here. My favorite is the addition of version hashes to css,js, and wasm files to automatically invalidate browser caching issues. Be sure to update to the latest version of cargo leptos(v0.2.8) to test out this feature. As always, big thanks to our returning contributors and welcome to the new folks!

0.6.3

This is release for our new server functions rewrite and Axum 0.7 support.
This should be a relatively feature-rich release, with limited breaking changes.

Migration

Actix

  • You can remove any explicit .handle_server_fns() call in your main.rs, as server functions are now handled in .leptos_routes()
  • The current extract function has been removed, and replaced with a new extract that has the same API as the current extractor. I think this API is strictly better, but please share feedback if you disagree.

Axum

  • This release supports Axum 0.7, so you'll need to migrate from Axum 0.6. The easiest way to do this is probably to consult the diff on one of the examples. (Note that along with Axum 0.7, you'll need to update to http 1.0 and tower_http 0.5.)
  • You can remove any explicit .handle_server_fns() call in your main.rs, as server functions are now handled in .leptos_routes()
  • The current extract function has been removed, and replaced with a new extract that has the same API as the current extractor. I think this API is strictly better, but please share feedback if you disagree.
  • RequestParts has been removed, as http::request::Parts now implements Clone: any use_context::<RequestParts>() should be updated to use Parts directly instead.

ServerFnError::new()

The addition of custom error types means that constructing ServerFnError inside server functions can cause type inference errors:

let oops = Err(ServerFnError::ServerError("No server state".to_string()));
return oops;  // this is fine
oops? // this is not: cannot infer type of the type parameter `E` declared on the enum `ServerFnError`

As a result, we've added a helper ServerFnError::new which simply constructs a ServerFnError::<NoCustomError>::ServerError:

let oops = Err(ServerFnError::new("No server state"));
return oops;  // this is fine
oops? // this is also fine now

This has the benefit of being more concise than the earlier pattern in any case.

Features

A rewritten server function system that is backwards-compatible, but reduces binary size and increases flexibility, specifically by allowing

  • automatic setup of server fn handlers with .leptos_routes() from the integrations
  • a variety of additional built-in encodings (rkyv, multipart forms/file uploads) in addition to the current set (GET URL, POST URL, CBOR, Rkyv) (#1868, #1989)
  • support for streaming responses from server functions (#1284)
  • ability to create custom user encodings for input and output by deriving IntoReq, FromReq, IntoRes, and/or FromRes traits
  • ability to mix and match encodings easily: This server function should be a JSON POST request and a ByteStream response, this one should be GET URL request and an rkyv response, etc.; any combination of the encodings above is supported
  • custom error types (#1657)
  • a #[middleware] macro to add per-server-function middleware from the Tower or Actix ecosystems (#1461)

Note: The additional included encodings (serde_lite, rkyv, multipart form data) are all enabled by additive features on the server_fn crate. If you want to use them you can just add that crate as a dependency and enable the required features.

Example: You can find a comprehensive example of these new features in the new server_fns_axum example.
