Comparing Dapr Developer Tools for Efficient Development

Discover the top Dapr developer tools like the Dapr CLI, VS Code Extension, Conductor Free, and others, comparing their strengths and weaknesses to help you choose the right one for your projects.

Comparing Dapr Developer Tools for Efficient Development

Dapr is a tool for building distributed systems that increases developer productivity by up to 30%, based on recent studies. It runs as a sidecar, shared process, or serverless API in the cloud and developers use Dapr SDKs in various languages or the runtime's native HTTP/gRPC features to interact with it. Frequent building and deploying to a development environment is essential in this process to verify functionality, identify errors, and refine iteratively. This process, also known as the inner loop, involves setting up a sidecar, ensuring all necessary components like message brokers and state stores are available, and eventually deploying and verifying the entire application on a local Kubernetes instance.

Inner vs Outer loop differences

The inner developer loop varies with different languages, runtimes, dependencies, and deployment targets. The motivation for this blog post arises from the different tools available on the market, each varying significantly based on use case and complexity, which can make selection daunting, especially for beginners. This article compares popular Dapr tools used in the inner development loop, discusses their pros and cons, and examines the different Dapr inner development flows (Part II). Lastly, we will also discuss  recommended tool combinations suited for optimizing development workflows. For those interested in operating Dapr, read my other blog on how Conductor Enterprise supports operations teams. We start with an overview of all native Dapr tools that exist today including their benefits and limitations.

Dapr CLI

If you are starting with Dapr, the Dapr Command Line Interface (CLI) is an essential tool, especially for local setups. It supports various operating systems and can operate with or without a container dependency but includes Kubernetes integrations for specific features. It's ideal for automating routine tasks, and quickly configuring and launching apps with Dapr sidecars.

Features

  • The Dapr CLI streamlines initializing Dapr on local systems and Kubernetes clusters. A single command (dapr init) sets up Dapr with default developer dependencies like Redis and Zipkin, along with the placement service for the Dapr Actors API , all set for use. It also provides features for deploying the control plane on Kubernetes and multi-application scenarios.
  • Its key feature is the ability to run an application locally with Dapr integration, allowing developers to see and test changes in real-time. It also has a multi-app run feature, particularly useful for simulating microservices environments where multiple services need to interact with each other for complex testing and validation scenarios.
  • It outputs application logs for troubleshooting and includes commands for event publishing and service calls in local (non-Kubernetes) environments.

Strengths

Dapr CLI is to Dapr what kubectl is to Kubernetes. It excels at setting up a local Dapr environment quickly, with all necessary configurations for immediate coding. Its run command launches single or multiple applications along with their respective sidecars:
