takaokouji · 2025-12-14T01:32:09Z

Summary

Implements the ability to save Scratch 3.0 projects (.sb3) to Google Drive with a custom dialog for specifying the filename and save location, addressing issue #428.

Key Features

Menu Integration: Added "Save to Google Drive" menu item in the File menu
Custom Save Dialog: Dialog with filename input and save location selection
Folder Selection: Users can save to My Drive root or select a specific folder using Google Picker
File Upload: Multipart upload using Google Drive Files API v3
Seamless Integration: Works with existing project saving mechanism

Implementation Details

New Files

src/containers/google-drive-saver-hoc.jsx
- Higher Order Component (HOC) for Google Drive save functionality
- Manages save dialog state and upload process
- Converts Ruby code to blocks before saving (using RubyToBlocksConverterHOC)
- Provides error handling and user feedback
src/components/google-drive-save-dialog/google-drive-save-dialog.jsx
- Custom dialog component for save operation
- Filename input with .sb3 extension validation
- Save location dropdown with two options:
  - "Google Drive - My Drive" (save to root)
  - "Google Drive - Select folder..." (opens folder picker)
- Action buttons: Cancel, Reset, Save
- Follows app.diagrams.net UI/UX design patterns
src/components/google-drive-save-dialog/google-drive-save-dialog.css
- Styling for save dialog
- Responsive design
- Consistent with existing Smalruby UI

Modified Files

src/lib/google-drive-api.js
- Added uploadFile() method for multipart upload to Google Drive
- Added showFolderPicker() method for folder selection
- Added handleFolderPickerResponse() for handling folder picker callbacks
- Uses base64 encoding for binary file data
src/components/menu-bar/menu-bar.jsx
- Added "Save to Google Drive" menu item after "Save to your computer"
- Integrated GoogleDriveSaverHOC into component composition
- Added GoogleDriveSaveDialog component to render method
- Added PropTypes for new props
src/locales/ja.js
- Added Japanese translations for all new UI elements
- Includes messages for menu item, dialog labels, buttons, and error messages

Technical Approach

Reuses Existing Infrastructure

Authentication: Uses existing OAuth 2.0 flow from GoogleDriveLoaderHOC
Script Loading: Leverages google-script-loader.js for dynamic loading
OAuth Scope: drive.file scope (already configured in PR Add Google Drive file loading functionality #427)
- This scope allows both reading and writing files created by the app

Upload Flow

User clicks "Save to Google Drive" from File menu
Custom dialog displays with:
- Pre-filled filename (project title + .sb3)
- Save location dropdown
User selects save location:
- "My Drive": Saves to root (uses parents: ["root"])
- "Select folder...": Opens Google Picker in folder-only mode
User clicks "Save" button
Ruby code is converted to blocks
Project data is generated using vm.saveProjectSb3()
File is uploaded to Google Drive using multipart upload
Success/error message is displayed

Multipart Upload

Uses Google Drive Files API v3 with multipart upload format:

Metadata (JSON): filename, MIME type, parent folder
File content (base64): .sb3 binary data
Boundary delimiter for multipart sections

Error Handling

Configuration validation (Google API credentials)
User-friendly error messages
Graceful handling of authentication failures
Proper cleanup on dialog cancellation

UI/UX Reference

The dialog design follows app.diagrams.net's save dialog:

Clear Japanese labels (名前を付けて保存, タイプ, Where)
Dropdown for save location selection
Standard action buttons (キャンセル, リセット, 保存)

See Issue #428 for reference screenshots.

Testing

Manual Testing

Tested the following scenarios:

✅ Menu item displays correctly
✅ Dialog opens with pre-filled filename
✅ Save to My Drive root works
✅ Folder selection opens Google Picker
✅ Cancel button closes dialog without errors
✅ Reset button resets form fields

Lint and Build

✅ All lint checks pass: npm run test:lint
⏳ Build test pending (requires ~300 seconds)

Breaking Changes

None. This is a new feature that doesn't affect existing functionality.

Configuration

Uses the same environment variables as the load functionality:

GOOGLE_CLIENT_ID: OAuth 2.0 Client ID
GOOGLE_API_KEY: API Key for Google Picker API

See docs/google-drive-setup.md for setup instructions.

Upload progress indicator
Support for saving to shared drives
Recent folders quick access

The MenuBar component now uses GoogleDriveSaverHOC, which wraps it with RubyToBlocksConverterHOC. This HOC requires `targets` and `rubyCode` state slices in the Redux store. The test's mock store was missing these state slices, causing the tests to fail with: TypeError: Cannot read properties of undefined (reading 'editingTarget') Added the missing state slices with their initial values from the respective reducers: - targets: sprites, stage, editingTarget, highlightedTargetId, highlightedTargetTime - rubyCode: target, code, modified, errors, markers This fixes the CI failures in PR #429. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
