Dapr Has a Free API — Microservice Building Blocks for Any Language

TL;DR Dapr (Distributed Application Runtime) provides building blocks for microservices — service invocation, state management, pub/sub, bindings, secrets, and more. It's language-agnostic, free, and runs as a sidecar next to your app. What Is Dapr? Dapr gives you microservice primitives via HTTP/gRPC APIs: Service invocation — call other services with built-in retries and mTLS State management — pluggable state stores (Redis, PostgreSQL, CosmosDB) Pub/Sub — event-driven messaging (Kafka, RabbitMQ, Redis) Bindings — input/output bindings to external systems Secrets — unified secret management API Actors — virtual actor pattern for stateful objects Free — Apache 2.0, CNCF incubating project Quick Start # Install Dapr CLI curl -fsSL https://raw.githubusercontent.com/dapr/cli/master/install/install.sh | bash # Initialize Dapr (local Docker) dapr init # Run your app with Dapr sidecar dapr run --app-id my-api --app-port 3000 -- node server.js Service Invocation // Call another service throu
