Creating and Calling a Secure Meteor Server Method to Insert Data
Learn how to create a Meteor server method that validates input, checks user authentication, inserts a document safely, and returns its _id to the client.
Meteor Publication/Subscription Model: How Reactive Data Sync Works and Where It Breaks
Meteor's publication/subscription model keeps client caches in sync by streaming MongoDB cursor diffs over DDP. This guide explains the mergebox, shows a worked active-tasks example, and covers parameterized pubs, field projections, reactive joins, and mergebox scaling limits.
Diagnosing 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.
mongodbMeteor Publish Functions as Server-Side Data Boundaries
Publish functions define the server‑side data boundary in Meteor. Explicit selectors and field projections limit what the Oplog tail watches and what each client receives.
Meteor Live Queries: Real‑Time Data Sync & Setup Guide
Meteor’s live queries push server‑side MongoDB changes to clients via DDP, enabling UI updates. This guide walks through the replica‑set requirement, a Posts example, and trade‑offs like bandwidth and security. Verify with Meteor.status() and keep cursors lean for performance.
When the UI Lies on Purpose: Meteor's Latency Compensation in Practice
Meteor methods run twice — once as a client-side simulation, once on the server. Here's how latency compensation actually reconciles, where it breaks, and how to verify it.
Secure Meteor Publications: Limiting Data Over-Fetch with Field Selectors
Learn how to limit Meteor publications to only the fields clients need, preventing accidental data exposure while keeping real‑time sync.
Handling Latency in Meteor: Mastering Method Simulation
Learn how Meteor's Method simulation enables optimistic UI updates and how to prevent 'UI flicker' and security leaks when sharing logic between client and server.
