mongodbDiagnosing Latency and Performance Degradation in Meteor.js Applications
Learn how to diagnose and fix latency spikes in Meteor.js by optimizing DDP publications, resolving MongoDB collection scans, and preventing event loop blockage.
Long-lived Resume Tokens vs. Short-lived Session Expiry for Least-Privilege Access
Meteor's accounts-base package implements a session management system based on hashed login tokens stored in users.services.resume.loginTokens . By default, these tokens allow clients to silently re-authenticate via DDP for approximately 90 days, which may conflict with security requirements for applications requiring strict least-privilege access and freque
Memory leak during DDP cursor cleanup on low-tier instances
When hosting low-traffic Meteor applications on minimal-memory cloud instances, the publish-subscribe mechanism often leads to unexpected memory exhaustion. The Distributed Data Protocol (DDP) maintains persistent connections to facilitate real-time synchronization, which creates a server-side state footprint for every active subscription. Specifically, when
