External packages this repository depends on, separated by package and category.

Root devDependencies (package.json)

These are workspace-wide tooling deps, shared by every package via pnpm hoisting.

packages/solid/package.json

Runtime dependencies

Package	Version	Used for
csstype	^3.1.0	TypeScript types for the JSX style attribute.
seroval	~1.5.0	Promise / resource serialization for streaming SSR. Imported by packages/solid/web/server/.
seroval-plugins	~1.5.0	Extra serializers (URL, Headers, Request) used in the web server build.

These are the only runtime deps. The reactive runtime, store, and JSX-less front ends ship without any further runtime dependencies.

packages/babel-preset-solid/package.json

Runtime dependencies

Package	Version	Used for
babel-plugin-jsx-dom-expressions	^0.40.6	The actual JSX transform.

Peer dependencies

Package	Version	Notes
@babel/core	^7.0.0	Babel host.
solid-js	^1.9.12	Optional — flagged via peerDependenciesMeta.solid-js.optional = true. The preset can run without solid-js installed (e.g. in compile-only contexts).

packages/solid-element/package.json

Runtime dependencies

Package	Version	Used for
component-register	^0.8.7	Custom Element registration, V1 standards, ShadyCSS Polymer polyfill.

Peer dependencies

Package	Version
solid-js	^1.9.12

devDependencies

Package	Version
solid-js	workspace:*

packages/solid-ssr/package.json

devDependencies

Package	Version	Used for
@babel/core, @rollup/plugin-babel, @rollup/plugin-commonjs, @rollup/plugin-node-resolve	latest	Building the example servers.
babel-preset-solid	workspace:*	JSX transform for the example apps.
express	^4.20.0	The example servers.
rollup	^3.20.0	Bundler used by the per-example configs (note: 3.x, the root uses 4.x).
rollup-plugin-copy	^3.4.0	Copies static assets in the SSG example.
solid-js	workspace:*	The runtime.

packages/test-integration/package.json

Runtime dependencies

Package	Version	Used for
babel-preset-solid	workspace:*	The smoke-test pulls in compiled JSX.
solid-js	workspace:*	The package under test.

devDependencies

Package	Version	Used for
gitly	^2.2.1	Used by the Vitest integration sub-suite to clone/probe templates.
shelljs	^0.8.5	Cross-platform shell utilities.

Notable transitively-pinned packages

pnpm.overrides in the root package.json:

"overrides": {
  "babel-preset-solid": "workspace:*"
}

This forces every transitive consumer of babel-preset-solid to use the workspace version, so internal example builds never accidentally pull a published copy from npm.

Sibling libraries (out-of-tree)

Three packages live in the ryansolid/dom-expressions repository and are bumped together:

• dom-expressions — DOM and SSR runtime + JSX types
• babel-plugin-jsx-dom-expressions — JSX → runtime-call transform
• hyper-dom-expressions — HyperScript factory builder
• lit-dom-expressions — Tagged-template factory builder

Solid's release cadence is tightly coupled to these; you will see commits like Update dom-expressions packages to 0.40.6 (Mar 2026) and Bump seroval from 1.3.1 to 1.4.1 (#2577) across git log.

Where to look for upgrades

• dom-expressions family — bump in the root devDependencies (workspace deps), then update packages/babel-preset-solid/package.json's babel-plugin-jsx-dom-expressions runtime dep to match.
• seroval — bump in both the root devDependencies and packages/solid/package.json runtime deps.
• TypeScript / Rollup / Vitest — root only.
• component-register — packages/solid-element/package.json only.
