perf(sdk): split twenty-sdk barrel into per-purpose subpaths to cut logic-function bundle ~700x (#19834)
## 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
- [ ] CI green

Improve application ast (#17016)
# Summary
- Introduces a new, flexible folder structure for Twenty SDK
applications using file suffix-based entity detection
- Adds defineApp, defineFunction, defineObject, and defineRole helper
functions with built-in validation
- Refactors manifest loading to use jiti runtime evaluation for
TypeScript config files
- Separates validation logic into dedicated module with comprehensive
error reporting
# New Application Folder Structure
Applications now use a convention-over-configuration approach where
entities are detected by their file suffix, allowing flexible
organization within the src/app/ folder.
