Here's what was done: **Created `lib/browser-engine.ts`** — Transformers.js pipeline for in-browser WebGPU inference: - Singleton pipeline pattern with lazy loading (loads on first `generate()` call) - Uses `onnx-community/Qwen2.5-0.5B-Instruct` with `q4f16` quantization on WebGPU - Status event system (`onStatusChange`) for UI progress tracking (idle → downloading → loading → ready → generating) - Handles both chat-mode and plain-mode pipeline output shapes - Pipes output through `cleanResponse()` automatically **Updated `lib/clean-response.ts`** — Added `` block stripping as the first cleaning operation: - Regex `^[\s\S]*?<\/think>\s*` handles empty blocks, multiline content, and trailing whitespace - Runs before markdown fence removal so the pipeline is: strip think → strip fences → strip backticks → strip prompts → strip preambles → strip comments **Fixed pre-existing build issue** — Excluded `relay/` from `tsconfig.json` (it has unresolved `uuid`/`better-sqlite3` type deps that were breaking `next build`).

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Step complete. Here's what was done: - **Installed** `@webcontainer/api` - **Created `lib/webcontainer-sandbox.ts`** — singleton WebContainer with `bootSandbox()`, `execCommand()`, `teardownSandbox()`, and `isSandboxReady()`. Mounts a `/workspace` directory and spawns `sh -c` for command execution. - **Created `hooks/use-webcontainer.ts`** — React hook with lazy-loading via dynamic import, auto-boot on first execute, execution state tracking, and command history accumulation. Returns `ExecutionResult` compatible with existing UI. - **Made `auditId` optional** in `types/sandbox.d.ts` — WebContainer exec has no server-side audit trail. - **Updated `components/execution-output.tsx`** — conditionally renders the audit ID line only when present. All checks pass: zero type errors, zero lint errors, clean production build. --- .zenflow/tasks/new-task-7cad/plan.md | 13 ++-- components/execution-output.tsx | 8 +- hooks/use-webcontainer.ts | 107 +++++++++++++++++++++++++++ lib/webcontainer-sandbox.ts | 67 +++++++++++++++++ package-lock.json | 7 ++ package.json | 1 + types/sandbox.d.ts | 2 +- 7 files changed, 195 insertions(+), 10 deletions(-) create mode 100644 hooks/use-webcontainer.ts create mode 100644 lib/webcontainer-sandbox.ts diff --git a/.zenflow/tasks/new-task-7cad/plan.md b/.zenflow/tasks/new-task-7cad/plan.md index a4cf74e..c3335ef 100644 --- a/.zenflow/tasks/new-task-7cad/plan.md +++ b/.zenflow/tasks/new-task-7cad/plan.md @@ -39,15 +39,16 @@ Create `lib/browser-engine.ts` (Transformers.js pipeline for in-browser WebGPU i --- -### [ ] Step: Build WebContainer sandbox +### [x] Step: Build WebContainer sandbox + Create the in-browser sandbox using WebContainers to replace the Docker relay for demo use. -- Install `@webcontainer/api` -- Create `lib/webcontainer-sandbox.ts` (boot, exec, teardown singleton) -- Create `hooks/use-webcontainer.ts` (React hook: boot-on-first-run, exec, history tracking) -- Update `types/sandbox.d.ts` to make `auditId` optional -- Verify: `npx tsc --noEmit && npm run lint && npm run build` +- [x] Install `@webcontainer/api` +- [x] Create `lib/webcontainer-sandbox.ts` (boot, exec, teardown singleton) +- [x] Create `hooks/use-webcontainer.ts` (React hook: boot-on-first-run, exec, history tracking) +- [x] Update `types/sandbox.d.ts` to make `auditId` optional +- [x] Verify: `npx tsc --noEmit && npm run lint && npm run build` --- diff --git a/components/execution-output.tsx b/components/execution-output.tsx index d245776..22a74c3 100644 --- a/components/execution-output.tsx +++ b/components/execution-output.tsx @@ -69,9 +69,11 @@ export function ExecutionOutput({ result, command }: ExecutionOutputProps) { {/* Audit trail reference */} -

Here's what was implemented: **`hooks/use-translate.ts`** - Added `InferenceMode` type (`cloud` | `browser` | `auto`), `browserStatus` tracking, and mode-aware translation. Cloud mode calls `/api/translate`, Browser mode uses Transformers.js `generate()` directly, Auto mode uses browser if the model is ready, otherwise falls back to cloud. Browser engine status subscription is lazy (only when mode is non-cloud). **`components/shell-session.tsx`** - Added a segmented mode selector (Cloud/Browser/Auto) with lucide icons next to the input label. Replaced `useSandbox()` with `useWebContainer()` for in-browser command execution. Added browser engine download progress bar (shown during model download/initialization). Added sandbox boot/execute status indicator. Sandbox is enabled by default (`!== "false"` instead of `=== "true"`). WebContainer command history is passed to `ExecutionOutput`. **`components/execution-output.tsx`** - Added `history` prop that renders previous sandbox commands above the current output in a dimmed terminal style with a separator. Added scrollable container (`max-h-[400px]`) for long output. `auditId` remains optional. All checks pass: `tsc --noEmit`, `lint`, and `build`. --- .zenflow/tasks/new-task-7cad/plan.md | 13 +-- components/execution-output.tsx | 36 ++++++- components/shell-session.tsx | 145 ++++++++++++++++++++++----- hooks/use-translate.ts | 108 ++++++++++++++------ 4 files changed, 235 insertions(+), 67 deletions(-) diff --git a/.zenflow/tasks/new-task-7cad/plan.md b/.zenflow/tasks/new-task-7cad/plan.md index c3335ef..fb8327d 100644 --- a/.zenflow/tasks/new-task-7cad/plan.md +++ b/.zenflow/tasks/new-task-7cad/plan.md @@ -52,15 +52,16 @@ Create the in-browser sandbox using WebContainers to replace the Docker relay fo --- -### [ ] Step: Wire up UI — mode selector, browser translate, sandbox execution +### [x] Step: Wire up UI — mode selector, browser translate, sandbox execution + Integrate browser inference and WebContainer sandbox into the main UI. -- Add inference mode selector (Cloud / Browser / Auto) to `components/shell-session.tsx` -- Update `hooks/use-translate.ts` to accept mode parameter and call browser engine directly in browser mode -- Replace `useSandbox()` with `useWebContainer()` in shell-session for WebContainer execution -- Update `components/execution-output.tsx` for optional auditId and command history display -- Verify: `npx tsc --noEmit && npm run lint && npm run build` +- [x] Add inference mode selector (Cloud / Browser / Auto) to `components/shell-session.tsx` +- [x] Update `hooks/use-translate.ts` to accept mode parameter and call browser engine directly in browser mode +- [x] Replace `useSandbox()` with `useWebContainer()` in shell-session for WebContainer execution +- [x] Update `components/execution-output.tsx` for optional auditId and command history display +- [x] Verify: `npx tsc --noEmit && npm run lint && npm run build` --- diff --git a/components/execution-output.tsx b/components/execution-output.tsx index 22a74c3..80fcfe5 100644 --- a/components/execution-output.tsx +++ b/components/execution-output.tsx @@ -2,12 +2,24 @@ import type { ExecutionResult } from "@/types/sandbox"; +interface HistoryEntry { + command: string; + stdout: string; + exitCode: number; + timestamp: number; +} + interface ExecutionOutputProps { result: ExecutionResult; command: string; + history?: HistoryEntry[]; } -export function ExecutionOutput({ result, command }: ExecutionOutputProps) { +export function ExecutionOutput({ + result, + command, + history, +}: ExecutionOutputProps) { const hasStdout = result.stdout.trim().length > 0; const hasStderr = result.stderr.trim().length > 0; const isSuccess = result.exitCode === 0; @@ -39,8 +51,26 @@ export function ExecutionOutput({ result, command }: ExecutionOutputProps) { {/* Output */} -
