Structured Logging Standardizer
Implement consistent, queryable, correlated logs.
Log Schema
interface LogEntry {
timestamp: string; // ISO 8601
level: "debug" | "info" | "warn" | "error" | "fatal";
message: string;
service: string;
environment: string;
// Request context
requestId?: string;
traceId?: string;
userId?: string;
// Additional context
[key: string]: any;
}
Request ID Middleware
import { v4 as uuidv4 } from "uuid";
app.use((req, res, next) => {
// Generate or use existing request ID
req.id = req.headers["x-request-id"] || uuidv4();
// Add to response headers
res.setHeader("x-request-id", req.id);
// Store in async local storage
asyncLocalStorage.run(new Map(), () => {
asyncLocalStorage.getStore()?.set("requestId", req.id);
next();
});
});
// Logger with request context
const logger = pino({
mixin() {
return {
requestId: asyncLocalStorage.getStore()?.get("requestId"),
};
},
});
Standardized Logger
class StandardLogger {
private logger = pino();
info(message: string, context?: Record<string, any>) {
this.logger.info(
{
...this.getContext(),
...context,
},
message
);
}
error(message: string, error?: Error, context?: Record<string, any>) {
this.logger.error(
{
...this.getContext(),
...context,
error: {
message: error?.message,
stack: error?.stack,
name: error?.name,
},
},
message
);
}
private getContext() {
return {
requestId: asyncLocalStorage.getStore()?.get("requestId"),
userId: asyncLocalStorage.getStore()?.get("userId"),
};
}
}
Best Practices
// ✅ DO: Structured fields
logger.info({ userId: '123', action: 'purchase', amount: 99.99 }, 'Purchase completed');
// ❌ DON'T: String interpolation
logger.info(\`User 123 purchased for $99.99\`);
// ✅ DO: Consistent field names
logger.info({ duration_ms: 150 }, 'Request completed');
// ❌ DON'T: Inconsistent naming
logger.info({ durationMs: 150 }, 'Request done');
