Unleashing New Features for Developers

The Microsoft Dev Proxy team has just released version 0.27, and it's a game-changer for developers! This update is all about elevating the developer experience with exciting new functionalities designed to simplify API spec generation and boost editing suggestions, while also paving the way for revolutionary AI integrations.

What is Dev Proxy?

For those not in the loop, Dev Proxy (formerly known as Microsoft 365 Developer Proxy) is a command-line tool that simulates real API behavior during app testing. This powerful tool enables developers to build robust applications that can handle real-world errors and limitations like a pro!

Revolutionary TypeSpec Generation

One of the standout features in this release is the ability to generate TypeSpec definitions straight from intercepted requests. What’s TypeSpec, you ask? It’s an innovative way to model APIs and generate code seamlessly across various ecosystems. This update means that API modeling just got a whole lot faster—akin to generating OpenAPI specifications, but with added flair!

Enter the Experimental MCP Server!

But that’s not all! Say hello to the experimental Dev Proxy MCP server. This nifty feature allows users to configure Dev Proxy using natural language, acting like a personal assistant guiding you through the platform's features. Pairing the Model Context Protocol (MCP) with AI agents, this innovation aims to make configuration a breeze.

Broadening Accessibility

Currently, this feature is in an experimental phase for Visual Studio Code insiders, with wider access expected via npm soon.

Enhanced Language Model Connections

The Dev Proxy team has also made major strides in refining the local Language Model (LM) connection. They’ve skillfully decoupled the connection logic from Ollama, allowing Dev Proxy to connect with any AI model client that supports OpenAI-compatible APIs. This means you can now link to the AI providers you love!

Improved JSON Schemas and Mock Handling

Additionally, JSON schemas in Dev Proxy have undergone significant upgrades, now featuring detailed descriptions and markdown support. Developers will find it easier to navigate and configure properties, especially within Visual Studio Code. Plus, URL intercepting and mock reloading have seen improvements—no more multiple reloads for mock files—making performance smoother and more efficient!

Dev Proxy Toolkit Gets A Refresh!

Last but not least, the Dev Proxy Toolkit extension for Visual Studio Code has received a revamp! It now includes new commands for creating configuration files and restarting Dev Proxy, as well as updated code snippets that incorporate the latest schema and TypeSpecGeneratorPlugin configurations.

Why Upgrade?

This update not only boosts performance but also makes developing with APIs much more intuitive. With the integration of AI and a smoother workflow, Dev Proxy 0.27 sets the stage for developers to create exceptional applications effortlessly. Don’t get left behind; upgrade to Dev Proxy 0.27 today and experience the future of API modeling!
