chore(deps-dev): bump vite from 7.3.3 to 8.2.1 - #1126

Overview

Bump vite from 7.3.3 to 8.2.1 in the four packages that use it (html, ts-example, ts-example-selected-features, ts-example-without-defaults).

Vite 8 replaces Rollup and esbuild with Rolldown and Oxc, which is a breaking change for the build configuration of the vite examples. Migration follows the official guide.

Configuration migration

• build.rollupOptions becomes build.rolldownOptions.
• The object form of output.manualChunks no longer exists. It is replaced by output.codeSplitting.groups, not by output.advancedChunks, which is already deprecated in the Rolldown version bundled with Vite 8.
• A group captures modules by matching their id, whereas the removed object form matched a package name. Since Vite resolves symlinks to their real path, the ids of @maxgraph/core point to the workspace directory and never to node_modules. A name-based regex would therefore silently produce no maxgraph chunk in this repository. The configurations resolve the package directory instead, which keeps the chunk correct both here and for a standalone consumer.

Two companion bumps, both mandatory

These are not opportunistic updates, the install cannot resolve without them:

• Storybook 10.1 to 10.5.7 (and the root eslint-plugin-storybook): @storybook/builder-vite@10.1 declares vite: ^5 || ^6 || ^7. Vite 8 support starts at 10.3.
• @types/node ^18.19.123 to ^24.10.7: Storybook 10.5 pulls an optional vite-plus and vitest@4 peer chain requiring @types/node 20 or later. Version 24 also aligns with the version declared in .nvmrc, which was already inconsistent.

Bundle sizes

The Oxc minifier and Lightning CSS make every example smaller. The chunk size warning limits are meant to sit just above the current size so that a regression is reported, so they are recalibrated:

The ts-example limit was already stale: at v0.24.0 the chunk was 434.58 kB for a limit of 433, so that build was emitting a warning.

Notes

The lockfile is updated surgically, not regenerated. A full regeneration drifts 2530 transitive versions, including @types/react 18.2.58 to 19.2.18. React 19 types drop the global JSX namespace, which breaks the tsc run of the core package through @types/mdx (core sets skipLibCheck: false with no types restriction, so it type-checks every @types package in the tree). Worth knowing before any future full regeneration.

Validation. The full CI suite from CLAUDE.md passes locally: core build, test-check, 498 tests, ts-support, all examples, Storybook build, circular dependencies, check:npm-package and lint.

The chunk size guard was checked to be genuinely live under Rolldown rather than silently ignored: lowering ts-example to 428 does emit Some chunks are larger than 428 kB, while 429 does not, against an actual size of 428.51 kB.

No screenshots: this only changes build tooling and example bundling, with no runtime or rendering behaviour change in the library itself.
