@imqueue vs NATS: a framework and a transport are not the same choice
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.
read →Graceful shutdown and zero-drop deploys
Every deploy sends a kill signal to a process that is probably in the middle of something. Nothing 500s, no dashboard turns red, and the work is gone anyway. Here's what actually happens to an in-flight message on SIGTERM, and the drain that keeps it.
read →One isolated imq CLI home per @imqueue project
Every imq invocation shares one ~/.imq — one config, one pid registry, one set of logs. Here's how to give each project its own isolated CLI environment with IMQ_CLI_HOME, plus recipes for direnv, shell wrappers, per-client tokens and disposable sandboxes.
read →Internal APIs don't need to be REST
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.
read →From monolith to services: a low-risk first extraction
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.
read →@imqueue vs Moleculer: two takes on Node.js microservices
Moleculer is a full-featured microservices framework with many transporters; @imqueue is a focused, TypeScript-first RPC layer over a message queue. Here's an honest comparison to help you pick.
read →@imqueue vs NestJS microservices: framework vs transport
NestJS is a full application framework with a microservices module; @imqueue is a focused RPC transport. They're not really competitors — here's how they differ, where each is stronger, and how to run them together.
read →tRPC vs @imqueue: client–server types vs service–service RPC
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.
read →@imqueue/job vs BullMQ: Redis job queues compared
Both are Redis-backed job queues for Node.js. @imqueue/job is small, safe-by-default and scheduling-capable; BullMQ is the feature-rich one. Here's an honest split — plus the thing @imqueue does that BullMQ doesn't.
