- [@imqueue vs NATS: a framework and a transport are not the same choice](https://imqueue.org/blog/imqueue-vs-nats/) — 2026-08-03, Andrii Glushko: NATS is a messaging system; @imqueue is an RPC framework that happens to use one. Comparing them means deciding how much of the contract you want to write yourself — and whether your fleet is Node-only. — [markdown](https://imqueue.org/blog/imqueue-vs-nats/index.md)
- [How Node.js services talk to each other in 2026: the honest options](https://imqueue.org/blog/nodejs-service-communication-options-2026/) — 2026-08-03, Mykhailo Stadnyk: REST, gRPC, tRPC, NATS, a framework like NestJS or Moleculer, or RPC over a message queue. Six real approaches, what each one costs, and the two questions that actually decide it — including when @imqueue is the wrong answer. — [markdown](https://imqueue.org/blog/nodejs-service-communication-options-2026/index.md)
- [RPC over Redis in Node.js: patterns and pitfalls](https://imqueue.org/blog/rpc-over-redis-nodejs/) — 2026-07-23, Serhiy Morenko: How request/reply RPC over Redis actually works in Node.js — correlation, timeouts and at-least-once delivery, which of those @imqueue handles for you, and what it deliberately leaves to you: retrying a failed RPC call, coalescing duplicate concurrent calls with @lock, and the circuit breaker it does not ship. — [markdown](https://imqueue.org/blog/rpc-over-redis-nodejs/index.md)
- [RPC between Node.js microservices over a message queue](https://imqueue.org/blog/rpc-over-message-queue-nodejs/) — 2026-07-22, Mykhailo Stadnyk: Why route internal service-to-service calls through a message queue instead of HTTP or gRPC — and how @imqueue makes those calls fully typed with zero client boilerplate. — [markdown](https://imqueue.org/blog/rpc-over-message-queue-nodejs/index.md)
- [Type-safe service-to-service communication in TypeScript](https://imqueue.org/blog/type-safe-service-communication-typescript/) — 2026-07-19, Serhiy Morenko: End-to-end types across service boundaries are easy inside one process and hard the moment you cross a network. Here's how to keep them without hand-writing clients or maintaining a schema language. — [markdown](https://imqueue.org/blog/type-safe-service-communication-typescript/index.md)
- [Internal APIs don't need to be REST](https://imqueue.org/blog/internal-apis-dont-need-rest/) — 2026-06-27, Andrii Glushko: REST is a fine choice for public, resource-oriented APIs. For internal service-to-service calls it's often ceremony over a plain function call. Here's when to drop it and what to reach for instead. — [markdown](https://imqueue.org/blog/internal-apis-dont-need-rest/index.md)
- [From monolith to services: a low-risk first extraction](https://imqueue.org/blog/monolith-to-services-first-extraction/) — 2026-06-24, Andrii Glushko: You don't migrate a monolith by rewriting it. You extract one capability, keep everything else in place, and repeat. Here's a concrete, low-risk first step for a Node.js team. — [markdown](https://imqueue.org/blog/monolith-to-services-first-extraction/index.md)
- [tRPC vs @imqueue: client–server types vs service–service RPC](https://imqueue.org/blog/imqueue-vs-trpc/) — 2026-06-14, Andrii Glushko: tRPC gives you end-to-end types between a frontend and its backend. @imqueue gives you typed RPC between backend services over a queue. They solve adjacent — not competing — problems. — [markdown](https://imqueue.org/blog/imqueue-vs-trpc/index.md)
- [gRPC vs message-queue RPC for internal Node.js services](https://imqueue.org/blog/grpc-vs-message-queue-rpc/) — 2026-06-09, Mykhailo Stadnyk: gRPC is the default answer for typed RPC — and a great one, especially across languages. For an all-Node.js back-end, routing RPC through a queue trades some of gRPC's strengths for a lot less infrastructure. — [markdown](https://imqueue.org/blog/grpc-vs-message-queue-rpc/index.md)
