Bumps solid-js from 1.7.12 to 1.8.0.

Release notes

Sourced from solid-js's releases.

v1.8.0 - Bifröst

In Norse mythology, Bifröst (/ˈbɪvrɒst/), is a burning rainbow bridge that reaches between Midgard (Earth) and Asgard, the realm of the gods.

I am first to admit this is not the most exciting release from a feature standpoint. I was looking for cool code snippets but these changes are for the most part all under the hood. We are in that time period between the end of 1.x and the start of 2.0. We recently made our new reactive experiments public and continue to build those out in public with @​solidjs/signals. We need to build for the future while bridging the gap with the present.

This version is about addressing some of the fundamentals that will help projects like SolidStart move forward while we do the transition. Async and Resources need work and are too all in. It is great to have a solution but now that we have a better understanding we need to start breaking things apart into their fundamental pieces and exposing them in ways we can better leverage. And in Solid 1.8 a big part of that is rethinking serialization, our bridge between the server and the client.

A lot of our learning here has come from applying what we have learned when doing performance benchmarks for the work that has been funded by Google Chrome Aurora. In order to realize our goal we've had to update the foundations.

De-duping Streaming Serialization

This is the marquee feature of this release and is largely the work of @​lxsmnsyc. Solid has been able to serialize promises and do streaming for a couple of years now, but it was very special-cased. Now it is a generic mechanism.

This matters because it means that we have decoupled the promise serialization from Resources, and in so decoupled the whole "when the stream is done" from them. This opens up things like nested promises and being able to serialize more complicated data structures.

We now also have a mechanism now that deeply de-dupes data serialized across flushes. If the data is ever serialized during the request we won't send it again even if sent in different streaming chunks. This is important for features like Islands where you might pass the same props to multiple Islands across different Suspense boundaries and don't want to send the data more than once. This is very beneficial where that data can be accessed at varying depths (recursive comments in say a Hackernews site) or other recursive data structures.

Hydration Improvements

Fragments for Hydration have been a bit of a pain and we keep seeming to have different issues reported around element duplication. Most commonly this has been around where there are lazy component siblings or where the fragment is top-level. After looking into and fixing an issue for Astro I decided to look at some of the oldest bugs in Solid and found it was a similar bug.

In many cases, the DOM can change throughout Hydration while doing things like streaming but we need to pause and resume hydration because code isn't available yet. While we don't create elements during hydration, getting an accurate snapshot of the DOM for the current state for future list reconciliation is a process we've had a few tries at but in 1.8 we update this in a way that makes sure it doesn't get out of date.

Also in 1.8, we have added some performance improvements to hydration in the form of not redundantly setting attributes or props as the page hydrates similar to how we don't update text. This is all migration towards a future where we don't need to do as much hydration, but it is important to note that values will be kept as they were on the server rather than how they may compute at runtime during hydration.

Smaller Templates

In 1.7 we removed unnecessary closing tags from template strings. It was a bit painful because we were a bit overzealous at first. While I believe in the end we got to a good place, ultimately all but the simplest reductions have been hidden behind a compiler flag(omitNestedClosingTags). Thanks to work from @​intrnl we are implementing another template size reduction technique of removing unnecessary quotes. Quotes are actually not required by HTML in some cases and it can add up.

Other

Fix NGINX Server Side Includes

Comments led with # are treated as special directives for a few different servers so we've needed to change our open hydration markers to $. As usual, your version of Solid and the Babel Plugin should be the same to ensure this matches up.

Better Guards on Global Scripts

Solid uses an inline HydrationScript as a way to do processing before the framework and code have loaded. To handle things like event capture and streaming. However, we didn't do a good job of guarding the right thing when multiple were added to the same page, a situation that can happen in Micro-frontends or 3rd party Islands solutions. Now the script guards against duplicate inclusion.

With another release out, I'd like to thank everyone involved in this release and in the various efforts across our ecosystem. From everything from the Docs effort to the Playground infrastructure. We've started to tighten up on features for 1.x and moving towards our 2.0 efforts, so we ask for a bit of patience but in the coming months as we put out some RFCs for 2.0 I look forward to engaging you in discussions on the future of Solid.

Thanks, @​ryansolid

1.8.0 - 2023-10-09

I admit this is not the most exciting release from a feature standpoint. We are in that holding pattern between the end of 1.x and the start of 2.0. We recently made our new reactive experiments public and continue to build those out in public with @​solidjs/signals.

This version is more about addressing some of the fundamentals that will help us in other projects like SolidStart while we do the transition. A big part of this is applying what we have learned when doing performance benchmarks for the work that has been funded by Google Chrome Aurora.

Async and Resources need work and are too all in. It is great to have a solution but now that we have a better understanding we need to start breaking things apart into their fundamental pieces.

1.7.0 - 2023-03-30

Solid has experienced incredible growth in usage the last 6 months. Companies are using it to power production applications and SolidStart Beta has been a big part of that. As a natural part of this growth and increased use at scale we are continuing to learn what works well and what the rough edges in Solid are today.

This v1.7 release marks the beginning of the migration roadmap to v2.0. We are beginning to re-evaluate core APIs and will begin introducing new ones while reasonably deprecating older ones in a manner that eases breaking changes. Our intention is to ease the broader ecosystem into preparing for improvements that a major 2.0 will unlock for the whole community.

Improved TypeScript

Null-Asserted Control Flow

One of the pains of using Solid with TypeScript has been that JSX control flows can't really type narrow. This is true, but starting with the migration to explicit keyed in v1.5 we now complete this story by introducing callback forms for <Show> and <Match> that work when non-keyed.

Looks like solid-js is up-to-date now, so this is no longer needed.
