httpYac

What httpYac is

httpYac is a free tool for creating and running API requests through a VS Code extension or command-line interface. It supports REST, SOAP, GraphQL, and gRPC, along with WebSocket requests. The CLI runs individual .http or .rest files, or all such files in a folder, and can return JSON output for continuous-integration workflows. Requests can include JavaScript tests and assertions to check responses and integrations. Authentication includes OAuth2, AWS, Basic, and Digest options, plus SSL client certificates. Variables and environments support dotenv and IntelliJ environment files, while Node.js scripts can add custom authentication and test logic. For documentation, httpBook presents requests in Jupyter Notebook format. The request language also supports MQTT, AMQP, and server-sent events, and a plugin system can add reusable features such as environments, variable substitution, and parser logic. Docker support is documented with the ghcr.io/anweber/httpyac image. The MIT-licensed project provides examples, troubleshooting guidance, plugin development material, and an API reference.
