OpenAPI Client Axios

openapi-client-axios is a JavaScript and TypeScript library designed to create dynamic API clients from OpenAPI v3 definitions at runtime. It leverages the popular axios library for HTTP requests, offering a powerful and flexible alternative to code generation for API consumption. The current stable version is 7.9.0. The library features automatic TypeScript type generation for API operations, full IntelliSense support, and a consistent API for calling operations using JavaScript methods based on operationIds. It operates isothermically in both browser and Node.js environments. Key differentiators include its no-code-generation approach, strong TypeScript integration, and reliance on existing, robust HTTP client infrastructure (axios), providing a predictable release cadence tied to upstream OpenAPI spec updates and axios releases.
