## Summary
`<input type=\"file\">` inside front-components was silently
non-functional:
- The host-side `serializeEvent` did not read `target.files`, so the
worker received an empty `onChange` detail.
- `SerializedEventData` had no `files` field.
- The `html-input` schema in `AllowedHtmlElements` exposed neither
`accept`, `multiple`, nor `capture` — the worker could not even
configure the picker.
This PR forwards file metadata (`name`, `size`, `type`, `lastModified`)
through the existing serialized event detail and accepts the missing
attributes on the `html-input` remote element. A new Storybook play test
guards the regression by uploading single and multiple files via
`userEvent.upload`.
Reading file contents inside the worker is intentionally out of scope
here and will need a separate host API bridge (the host has the `File`
objects on the real input element; passing bytes through `postMessage`
is a bigger design call).
## Problem
In the front-component sandbox, typing in the middle of a pre-filled
`<input>` or `<textarea>` caused the caret to jump to the end on every
keystroke. Characters appeared at the correct position, but editing
mid-string was effectively broken.
Root cause: the remote-DOM bridge round-trips every keystroke through
the
worker. By the time the updated `value` prop arrives back at the host,
React applies it by setting `inputElement.value = X` directly, which
browsers always reset the caret to the end.
Typing at the end was unaffected, which is why this went unnoticed in
search fields and similar append-only inputs.
## Fix
For text-like `<input>` types and `<textarea>`, the `value` prop is now
applied imperatively through a ref callback instead of being passed as a
React controlled prop:
- If the DOM value already matches the incoming prop, the assignment is
skipped entirely.
- If a write is needed and the element is focused, `selectionStart` and
`selectionEnd` are captured before the assignment and restored
afterwards with `setSelectionRange`.
Non-text input types (checkbox, radio, file, color, range) and all other
host elements are unaffected.
## Testing
Drop the repro from the issue into any front-component, click between
two
characters in the pre-filled value, and type — the caret should now stay
at the insertion point.

## Summary
Logic-function bundles produced by the twenty-sdk CLI were ~1.18 MB even
for a one-line handler. Root cause: the SDK shipped as a single bundled
barrel (`twenty-sdk` → `dist/index.mjs`) that co-mingled server-side
definition factories with the front-component runtime, validation (zod),
and React. With no `\"sideEffects\"` declaration on the SDK package,
esbuild had to assume every module-level statement could have side
effects and refused to drop unused code.
This PR restructures the SDK so consumers' bundlers can tree-shake at
the leaf level:
- **Reorganized SDK source.** All server-side definition factories now
live under `src/sdk/define/` (agents, application, fields,
logic-functions, objects, page-layouts, roles, skills, views,
navigation-menu-items, etc.). All front-component runtime
(components, hooks, host APIs, command primitives) lives under
`src/sdk/front-component/`. The legacy bare `src/sdk/index.ts` is
removed; the bare `twenty-sdk` entry no longer exists.
- **Split the build configs by purpose / runtime env.** Replaced
`vite.config.sdk.ts` with two purpose-specific configs:
- `vite.config.define.ts` — node target, externals from package
`dependencies`, emits to `dist/define/**`
- `vite.config.front-component.ts` — browser/React target, emits to
`dist/front-component/**`
Both use `preserveModules: true` so each leaf ships as its own `.mjs`.
- **\`\"sideEffects\": false\`** on `twenty-sdk` so esbuild can drop
unreferenced re-exports.
- **\`package.json\` exports + \`typesVersions\`** updated: dropped the
bare \`.\` entry, added \`./front-component\`, and pointed \`./define\`
at the new per-module dist layout.
- **Migrated every internal/example/community app** to the new subpath
imports (`twenty-sdk/define`, `twenty-sdk/front-component`,
`twenty-sdk/ui`).
- **Added \`bundle-investigation\` internal app** that reproduces the
bundle bloat and demonstrates the fix.
- Cleaned up dead \`twenty-sdk/dist/sdk/...\` references in the
front-component story builder, the call-recording app, and the SDK
tsconfig.
## Bundle size impact
Measured with esbuild using the same options as the SDK CLI
(\`packages/twenty-apps/internal/bundle-investigation\`):
| Variant | Imports | Before | After |
| ----------------------- |
------------------------------------------------------- | ---------- |
--------- |
| \`01-bare\` | \`defineLogicFunction\` from \`twenty-sdk/define\` |
1177 KB | **1.6 KB** |
| \`02-with-sdk-client\` | + \`CoreApiClient\` from
\`twenty-client-sdk/core\` | 1177 KB | **1.9 KB** |
| \`03-fetch-issues\` | + GitHub GraphQL fetch + JWT signing + 2
mutations | 1181 KB | **5.8 KB** |
| \`05-via-define-subpath\` | same as \`01\`, via the public subpath |
1177 KB | **1.7 KB** |
That's a ~735× reduction on the bare baseline. Knock-on benefits for
Lambda warm + cold starts, S3 upload size, and \`/tmp\` disk usage in
warm containers.
## Test plan
- [x] \`npx nx run twenty-sdk:build\` succeeds
- [x] \`npx nx run twenty-sdk:typecheck\` passes
- [x] \`npx nx run twenty-sdk:test:unit\` passes (31 files / 257 tests)
- [x] \`npx nx run-many -t typecheck
--projects=twenty-front,twenty-server,twenty-front-component-renderer,twenty-sdk,twenty-shared,bundle-investigation\`
passes
- [x] \`node
packages/twenty-apps/internal/bundle-investigation/scripts/build-variants.mjs\`
produces the sizes above

Add Storybook stories and example components to test event forwarding
through the front component renderer: form events (text input, checkbox,
focus/blur, submit), keyboard events (key/code/modifiers), and host API
calls (navigate, snackbar, progress, close panel)
- Add 72 missing HTML and SVG elements to the remote-dom component
registry (48 HTML + 24 SVG), bringing the total from 47 to 119 supported
elements
- HTML additions include semantic inline text (b, i, u, s, mark, sub,
sup, kbd, etc.), description lists, ruby annotations, structural
elements (figure, details, dialog), and form utilities (fieldset,
progress, meter, optgroup)
- SVG additions include containers (svg, g, defs), shapes (path, circle,
rect, line, polygon), text (text, tspan), gradients (linearGradient,
radialGradient, stop), and utilities (clipPath, mask, foreignObject,
marker)
- Add htmlTag override to support SVG elements with camelCase names
(e.g. clipPath, foreignObject) while keeping custom element tags
lowercase per the Web Components spec
