- Resolved Pyodide server-side rendering errors affecting 15+ e2e tests - Fixed by using dynamic imports for Pyodide and adding 'use client' directives - E2E tests improved: 236 passed (up from ~220), 26 failed (down from ~40+) - No functional breaking changes, critical runtime errors resolved Remaining 26 e2e test failures are mostly visual regression and cross-platform UI tests that require styling adjustments and baseline updates, not functional fixes.

# Ralph Loop Iteration 5 - Pyodide SSR Fixes
|
|
|
|
## Overview
|
|
This iteration focused on resolving Pyodide Server-Side Rendering (SSR) errors that were affecting approximately 15+ e2e tests.
|
|
|
|
## Problem Analysis
|
|
The issue was that Pyodide (a Python runtime for the browser) was being imported on the server side, which tried to access browser APIs in a Node.js environment. The error message was:
|
|
```
|
|
Error: Cannot determine runtime environment at (ssr)/./node_modules/pyodide/pyodide.mjs
|
|
```
|
|
|
|
### Root Cause
|
|
1. `src/lib/pyodide-runner.ts` had a top-level import: `import { loadPyodide } from 'pyodide'`
|
|
2. This file was imported by `PythonOutput.tsx` which was imported by `SplitScreenEditor.tsx`
|
|
3. `SplitScreenEditor` was imported directly (not dynamically) by `CodeEditorSection`
|
|
4. These components were part of the component tree on server-rendered pages
|
|
5. During the Next.js build process, Webpack tried to bundle Pyodide for server-side code, causing the error
|
|
|
|
## Solutions Implemented
|
|
|
|
### 1. Dynamic Imports for Pyodide (`src/lib/pyodide-runner.ts`)
|
|
Changed from top-level import to dynamic import inside the function:
|
|
```typescript
|
|
// Before:
|
|
import { loadPyodide } from 'pyodide'
|
|
|
|
// After:
|
|
const { loadPyodide } = await import('pyodide') // Only imported when actually needed
|
|
```
|
|
|
|
### 2. Client Component Directives
|
|
Added `'use client'` directives to components that use browser-only APIs or state:
|
|
- `src/components/features/python-runner/PythonOutput.tsx`
|
|
- `src/components/features/python-runner/PythonTerminal.tsx`
|
|
- `src/components/features/snippet-editor/SplitScreenEditor.tsx`
|
|
- `src/components/features/snippet-editor/CodeEditorSection.tsx`
|
|
|
|
This ensures these components are only rendered on the client side, never bundled for server-side execution.
|
|
|
|
## Results
|
|
- ✅ Eliminated all Pyodide SSR errors
|
|
- ✅ E2E tests: 236 passed (up from ~220)
|
|
- ✅ Failed tests: 26 (down from ~40+)
|
|
- ✅ No breaking changes to functionality
|
|
|
|
## Remaining Issues (Not in Scope for This Iteration)
|
|
- **Heading Hierarchy**: 2 tests - Minor accessibility issue with H1-H6 jumps on home page
|
|
- **Visual Regression**: 13 tests - Need baseline updates for font sizing, contrast, borders
|
|
- **Cross-Platform UI**: 6 tests - Navigation, touch events, text contrast on mobile
|
|
- **Mobile/Responsive**: 5 tests - Touch interaction, notch/safe area, line-height
|
|
|
|
These represent mostly styling and visual regression issues, not functional problems. The critical runtime errors have been resolved.
|
|
|
|
## Key Insights
|
|
This fix demonstrates the importance of understanding Next.js's server/client component boundary and how dynamic imports can be used to defer module loading until runtime when they're needed on the client side only.
