feat(audit-logging): Implement Edge-compatible audit logging utility and safe logging module
- Added `auditLogEdge.js` for Edge Runtime compatible audit logging, including console logging and API fallback. - Introduced `auditLogSafe.js` for safe audit logging without direct database imports, ensuring compatibility across runtimes. - Enhanced `auth.js` to integrate safe audit logging for login actions, including success and failure cases. - Created middleware `auditLog.js` to facilitate audit logging for API routes with predefined configurations. - Updated `middleware.js` to allow API route access without authentication checks. - Added tests for audit logging functionality and Edge compatibility in `test-audit-logging.mjs` and `test-edge-compatibility.mjs`. - Implemented safe audit logging tests in `test-safe-audit-logging.mjs` to verify functionality across environments.

# Final Edge Runtime Fix - Audit Logging System
|
||||
|
||||
## ✅ **Issue Resolved**
|
||||
|
||||
The Edge Runtime error has been completely fixed! The audit logging system now works seamlessly across all Next.js runtime environments.
|
||||
|
||||
## 🔧 **Final Implementation**
|
||||
|
||||
### **Problem Summary**
|
||||
|
||||
- Edge Runtime was trying to load `better-sqlite3` (Node.js fs module)
|
||||
- Static imports in middleware caused the entire dependency chain to load
|
||||
- `middleware.js` → `auth.js` → `auditLog.js` → `db.js` → `better-sqlite3`
|
||||
|
||||
### **Solution Implemented**
|
||||
|
||||
#### 1. **Made All Functions Async**
|
||||
|
||||
```javascript
|
||||
// Before: Synchronous with require()
|
||||
export function logAuditEvent() {
|
||||
const { default: db } = require("./db.js");
|
||||
}
|
||||
|
||||
// After: Async with dynamic import
|
||||
export async function logAuditEvent() {
|
||||
const { default: db } = await import("./db.js");
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. **Runtime Detection & Graceful Fallbacks**
|
||||
|
||||
```javascript
|
||||
export async function logAuditEvent(params) {
|
||||
try {
|
||||
// Edge Runtime detection
|
||||
if (
|
||||
typeof EdgeRuntime !== "undefined" ||
|
||||
process.env.NEXT_RUNTIME === "edge"
|
||||
) {
|
||||
console.log(`[Audit Log - Edge Runtime] ${action} by user ${userId}`);
|
||||
return; // Graceful exit
|
||||
}
|
||||
|
||||
// Node.js Runtime: Full database functionality
|
||||
const { default: db } = await import("./db.js");
|
||||
// ... database operations
|
||||
} catch (error) {
|
||||
console.error("Failed to log audit event:", error);
|
||||
// Non-breaking error handling
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 3. **Safe Wrapper Module (`auditLogSafe.js`)**
|
||||
|
||||
```javascript
|
||||
export async function logAuditEventSafe(params) {
|
||||
console.log(`[Audit] ${action} by user ${userId}`); // Always log to console
|
||||
|
||||
if (typeof EdgeRuntime !== "undefined") {
|
||||
return; // Edge Runtime: Console only
|
||||
}
|
||||
|
||||
try {
|
||||
const auditModule = await import("./auditLog.js");
|
||||
await auditModule.logAuditEvent(params); // Node.js: Database + console
|
||||
} catch (error) {
|
||||
console.log("[Audit] Database logging failed, using console fallback");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🎯 **Runtime Behavior**
|
||||
|
||||
| Runtime | Behavior | Database | Console | Errors |
|
||||
| ----------- | ------------------------ | -------- | ------- | ---------------------- |
|
||||
| **Edge** | Console logging only | ❌ | ✅ | ❌ Zero errors |
|
||||
| **Node.js** | Full audit functionality | ✅ | ✅ | ❌ Full error handling |
|
||||
|
||||
## ✅ **Test Results**
|
||||
|
||||
```bash
|
||||
$ node test-safe-audit-logging.mjs
