Requirement records for Rspress v2.0.0

[Timeless0911]

This thread is used to collect planned breaking changes and notable changes for Rspress v2.0.0 in the future

[Timeless0911]

Upgrade Rspack / Rsbuild v1.0.0

Rspress v2.0.0 will upgrade the dependent @rsbuild/core to v1.0.0 which will upgrade the dependent @rspack/core to v1.0.0.

Rspack v1.0.0 contains some breaking changes, see web-infra-dev/rspack#6315 for more details.

[Timeless0911]

@rsbuild/plugin-less and @rsbuild/plugin-sass now are built-in in rspress to avoid breaking changes. May be we can remove them in 2.0.

[Timeless0911]

Upgrade React 19

Support react 19 and maintain compatibility with react 18.

[Timeless0911]

Upgrade md and mdx related dependencies

Below dependencies may be need to upgrade:

• @mdx-js/loader
• @mdx-js/mdx
• @mdx-js/react
• hast-util-from-html
• mdast-util-mdxjs-esm
• rehype-external-links
• rehype-stringify"
• remark
• remark-gfm
• remark-html
• remark-parse
• remark-rehype
• unified
• unist-util-visit
• unist-util-visit-children
• @types/mdast

[chenjiahan]

Rspress uses mdx-rs by default, can we make the mdx-js packages as peer dependencies of an optional Rspress plugin? This can greatly reduce the dependencies of Rspress core.

[Timeless0911]

Now we still need mdx-js's AST parse to do something now, and @mdx-js/react is needed which provide MDXProvider in runtime.

We should sort out the related capabilities provided by mdx-js and port same features in rust mode.

[chenjiahan]

How about the remark-related packages? can we remove them

[Timeless0911]

If so, users who enable mdxRs: false need to manually install many deps in package.json?
