Microcks is a cloud-native API mocking and testing platform that ingests API specifications (OpenAPI, AsyncAPI, gRPC, GraphQL, Postman, SoapUI, HAR, and protobuf) and dynamically generates live mock endpoints and contract conformance tests. It supports REST, SOAP, GraphQL, gRPC, and asynchronous protocols (Kafka, RabbitMQ, MQTT, NATS, WebSocket, Amazon SQS/SNS, Google PubSub). The architecture consists of a main Spring Boot web application with an Angular frontend, a separate Quarkus-based async minion for event-driven mocking and testing, and optional dependencies on MongoDB, Keycloak, Kafka, and external message brokers. The system provides a rich set of features: dynamic response dispatching based on request parameters, scriptable mocks (Groovy/JavaScript), a template engine for dynamic content, SLA management, webhook notifications, AI-assisted sample generation via OpenAI, and OpenTelemetry-based observability. It is a well-engineered, modular project with extensive test coverage and a clean separation of concerns.
Stoplight Prism is an open-source HTTP mock server and validation proxy driven by OpenAPI specifications (v2, v3, v3.1) and Postman Collections. It provides two primary CLI commands: `prism mock` to simulate an API from a schema definition, and `prism proxy` to validate requests and responses against a spec while forwarding traffic to a real upstream. The architecture is a monorepo with four packages (`core`, `http`, `http-server`, `cli`) that implement a functional pipeline: route matching, input validation (body, headers, query/path parameters, security), content negotiation, and response generation (static examples or dynamic faker-generated data). It also supports callback mocking, CORS handling, and RFC 7807 problem detail errors. The codebase is written in TypeScript with heavy use of fp-ts for composable error handling and dependency injection via reader monads. While the project is mature and well-tested (unit, integration, and a text-based harness test suite), its tight coupling to Stoplight internal packages and the steep learning curve of fp-ts reduce its overall reusability for external projects. It is not a data research repository.
This is the Postman Collection SDK, a JavaScript library that provides a complete object model for Postman Collections (v2.1 format). It enables developers to create, manipulate, serialize, and deserialize collections, items, requests, responses, variables, and other HTTP-related constructs. The library is used internally by Postman's own tools (e.g., Newman, Postman app) and by third-party integrations. It features a class hierarchy rooted in PropertyBase, with PropertyList for generic indexed lists, variable substitution via SuperString, dynamic variable generation (faker-based), URL matching patterns, content-type detection, and mutation tracking. The codebase is well-tested (100% unit test coverage enforced) and includes both Node.js and browser support. While the core architecture is clean and modular, some dependencies are outdated (lodash 4.18.1, file-type 3.9.0) and there are deprecated API surfaces maintained for backward compatibility. The SDK is actively maintained with frequent releases and CI/CD pipelines.
This repository is a Node.js CLI tool that converts Postman collections into executable k6 JavaScript scripts for load testing. It reads Postman collection JSON (v1/v2) along with optional environment, globals, and data files, processes authentication methods, variables, pre-request/test scripts, and outputs a k6-compatible script. The architecture features distinct layers: input conversion (lib/convert), collection traversal and processing (lib/generate, lib/common), authentication strategies (lib/auth), and script rendering (lib/render). A shim layer (lib/shim) provides Postman API compatibility in the k6 environment using symbol-based state management and extension patterns. Despite the code demonstrating solid engineering practices, the project is explicitly unmaintained per its README, with development moved to a fork, and relies on outdated Node.js 11 in its Dockerfile.
