Open Source TypeScript HTTP Clients

TypeScript client generator from OpenAPI schema.

Ky targets modern browsers and Deno. For older browsers, you will need to transpile and use a fetch polyfill and globalThis polyfill. For Node.js, check out Got. For isomorphic needs (like SSR), check out ky-universal. It's just a tiny file with no dependencies. Internally, the standard methods (GET, POST, PUT, PATCH, HEAD and DELETE) are uppercased in order to avoid server errors due to case sensitivity. Search parameters to include in the request URL. Setting this will override all existing search parameters in the input URL. After prefixUrl and input are joined, the result is resolved against the base URL of the page (if any). The hook can return a Request to replace the outgoing request, or return a Response to completely avoid making an HTTP request. This can be used to mock a request, check an internal cache, etc. An important consideration when returning a request or response from this hook is that any remaining beforeRequest hooks will be skipped.

Generate custom HTTP responses, the simpler way to test your web services. Mocky is a simple app that allows to generate custom HTTP responses. It's helpful when you have to request a build-in-progress WS, when you want to mock the backend response in a single app, or when you want to test your WS client. Don't wait for the backend to be ready, generate custom API responses with Mocky and start working on your application straight away. Mocky is a free and unlimited online service. Mocky API is written in Scala with the HTTP4s server. Mocks are stored into PostgreSQL database with Doobie.

Infinitely transfer between every device over pure HTTP with pipes or browsers. Piping Server transfers data to POST /hello or PUT /hello into GET /hello. The path /hello can be anything such as /mypath or /mypath/123/. A sender and receivers who specify the same path can transfer. Both the sender and the recipient can start the transfer first. The first one waits for the other. The most important thing is that the data are streamed. This means that you can transfer any data infinitely. The demo below transfers an infinite text stream with seq inf. You can transfer any kind of data infinitely on a stream. Streams are very efficient in terms of both time and space. All you need is to have either a Web browser or curl, which are widely pre-installed. You do not need to install any extra software.

Swagger-to-GraphQL converts your existing Swagger schema to an executable GraphQL schema where resolvers perform HTTP calls to certain real endpoints. It allows you to move your API to GraphQL with nearly zero effort and maintain both REST and GraphQL APIs. Our CLI tool also allows you get the GraphQL schema in Schema Definition Language. This library will fetch your swagger schema, convert it to a GraphQL schema and convert GraphQL parameters to REST parameters. From there you are control of making the actual REST call. This means you can reuse your existing HTTP client, use existing authentication schemes and override any part of the REST call. You can override the REST host, proxy incoming request headers along to your REST backend, add caching etc.

Zan Proxy is an HTTP proxy server written in Node.js, which can be used to modify requests and mock response data. It is also a tool for custom DNS resolving and request monitoring. The proxy server can be easily configured by a user-friendly interface. In addition, a mechanism is provided for developers to customize the behavior of the server.

Shared API definitions based on Zod. Standalone typesafe API client based on Axios with parameters and response validation. Typesafe server based on Express with input validation. Really simple centralized API declaration, typescript autocompletion in your favorite IDE for URL and parameters, and typescript response types. Parameters and responses schema thanks to Zod, response schema validation, and powerful plugins like fetch adapter or auth automatic injection.

A non-invasive, simple, reliable collection of axios extension. It is highly recommended to enable the request logging recorder in the development environment(disabled by default). Besides configuring the request through the cacheAdapterEnhancer, we can enjoy more advanced features via configuring every individual request.
