Storybook Rsbuild
Goal
Set up Storybook on Rsbuild, or migrate an existing Storybook to it. Factual mappings — version compatibility, package names, install commands, config conversion patterns — live in upstream docs at storybook.rsbuild.rs. This skill is an action router and a behavioral checklist; it does not duplicate the docs.
Principles (must follow)
-
Single source of truth is upstream. Fetch the relevant storybook.rsbuild.rs page for version tables, install commands, and config conversion patterns. Do not infer version pins or package names from training memory — the ecosystem moves faster than the model's prior.
-
Pin from the framework guide's Requirements table. Each framework guide page (e.g. https://storybook.rsbuild.rs/guide/framework/react) carries a Requirements section listing the canonical compatible version ranges — that is the authoritative source for version pins. For fresh setups, install the latest stable storybook major and the matching storybook-rsbuild major. Do not pin from version numbers you see in code snippets elsewhere; only the docs are authoritative.
-
Declare @rsbuild/core directly. storybook-<framework>-rsbuild lists @rsbuild/core as a peer dependency, but you must still add @rsbuild/core to the project's own devDependencies so version pins and lockfile audits remain unambiguous and a future framework-package release that drops the peer cannot silently break the build.
-
Migration is one task with two ordered phases — both required. Phase A: install the new framework package and update config; leave the old framework package, old builder package, and old webpackFinal / viteFinal blocks in place so Verification has a rollback path. Phase B: as soon as Verification passes, in the same task, remove the old framework package (e.g. @storybook/react-webpack5, @storybook/vue3-vite), the old builder package (e.g. @storybook/builder-webpack5, @storybook/builder-vite), and the old webpackFinal / viteFinal block. A migration that ends with both builders' framework packages still in package.json is incomplete — leaving them is the most common silent regression in this skill's evals. Phase A on its own is not a valid stopping point; if you ran Verification, you must also run cleanup.
-
Preserve addons; never silently drop. When migrating, webpack-only addons (e.g. @storybook/addon-styling-webpack) must either be passed through webpackAddons (so upstream auto-translation handles them) or replaced with the equivalent Rsbuild-native pipeline (@rsbuild/plugin-postcss, tools.postcss, etc.). A migration that removes a styling addon and produces a passing storybook build but a visually broken story tree is still a regression.
-
Operate in scope. In monorepos, modify only the package that hosts stories. Do not edit business source files unless the migration strictly requires it.
Step 1 — Detect scenario
Read package.json and project structure to determine existing Storybook state:
- Check for
.storybook/ directory (in monorepos, check both root and per-package)
- Check
package.json for storybook scripts or @storybook/* / storybook-*-rsbuild in dependencies or devDependencies
- If Storybook exists and already uses
storybook-*-rsbuild → already set up; go to Configuration or Troubleshooting as needed
- If Storybook exists with a non-Rsbuild builder (
@storybook/*-webpack5, @storybook/*-vite, etc.) → go to Migration Workflow
- No Storybook found → go to Fresh Setup Workflow
Fresh Setup Workflow
1. Detect ecosystem integration
Read package.json dependencies and devDependencies, check in order:
If matched, read the integration guide and apply its constraints as an overlay alongside the steps below.
2. Detect UI framework
Infer the UI framework from app dependencies (react, vue, lit, etc.):
3. Set up Storybook
- In monorepos, operate in the package that will host stories
- Read and follow the framework guide matched above; install the latest stable
storybook major and the matching storybook-<framework>-rsbuild major (Principle 2)
- Add
@rsbuild/core to devDependencies directly, alongside storybook-<framework>-rsbuild (Principle 3)
- Ensure
.storybook/main.* uses the correct framework: '<storybook-*-rsbuild>'
- Ensure
package.json has storybook dev and storybook build scripts
- If no story file exists yet, scaffold at least one minimal example story (e.g.
src/stories/Example.stories.*) so Verification step 2 has something to render
- Run Verification below
Migration Workflow
Read the upstream migration guide: https://storybook.rsbuild.rs/guide/migration
Follow these steps in order:
- Detect migration type — read
.storybook/main.* (framework field and/or core.builder) and package.json dependencies to classify as "from webpack5" or "from Vite", then select the matching section in the migration guide
- Resolve version compatibility — read the "Version compatibility" section in the migration guide, select the correct
storybook-rsbuild major based on installed Storybook version
- Replace packages — apply the install/remove mapping from the migration guide using the project's package manager (detect from lockfile); only change packages required by the migration. Always add
@rsbuild/core as a direct devDep alongside the new framework package (Principle 3). Do not remove the old framework package or old devDeps yet — that happens after Verification (Principle 4)
- Update
.storybook/main.* — apply the config changes exactly as shown in the migration guide for the detected framework
- Migrate custom builder hooks — search for legacy builder hooks (
webpackFinal / viteFinal); if found, convert following the upstream configuration guide (https://storybook.rsbuild.rs/guide/configuration)
- Handle addon compatibility — keep addons unchanged initially. If a webpack-only addon must change, route it through
webpackAddons for upstream auto-translation, or replace it with the Rsbuild-native equivalent — never silently drop it (Principle 5). Consult the migration guide's addon section for the recommended fix
- Verify, then clean up — both required — run Verification below; once it passes, in the same task complete all of the following before reporting done (Principle 4):
- Remove the old framework package from
package.json devDependencies (e.g. @storybook/react-webpack5, @storybook/vue3-webpack5, @storybook/react-vite, @storybook/vue3-vite, @storybook/html-webpack5, @storybook/web-components-webpack5, etc.)
- Remove the old builder package if separately listed (e.g.
@storybook/builder-webpack5, @storybook/builder-vite)
- Delete the legacy
webpackFinal / viteFinal block from .storybook/main.*
- Drop any old-builder-only devDeps that no longer have consumers
- Re-run
pnpm install (or the project's package manager equivalent) so the lockfile reflects the cleanup
If a factual mapping is needed (version table, package names, conversion patterns) and not present in this skill, fetch it from the upstream docs — do not guess.
Verification
storybook dev starts without errors- At least one story renders correctly in the browser (a clean dev-server boot is not sufficient — a missing-glob in
stories or a broken framework wiring will only surface here)
- HMR works
storybook build completes- Check startup logs to confirm the Rsbuild builder is active (not webpack/vite)
Troubleshooting
- Cache issues: remove
node_modules/.cache/storybook and retry
- Residual config: if dev fails after migration, temporarily remove custom
rsbuildFinal block to isolate the issue, then re-add incrementally
- For debugging and other issues, consult the upstream migration guide's "Debugging" section and https://storybook.rsbuild.rs/guide/configuration
Edge Cases
- Monorepo: locate the package that hosts stories; operate there, not at root
- Multiple
.storybook/ dirs: pick the one referenced by package.json scripts
- TS path aliases: ensure aliases are preserved after migration; consult the upstream configuration guide for how to configure
rsbuildFinal
