Usage

renderResponse

Using renderResponse(req, options), you can render UI into a standard Response object from an incoming Request.

Example: Using srvx (same code works with Node.js, Deno, and Bun)

import { serve } from "srvx";
import { renderResponse } from "openapi-renderer";

serve({
  fetch(req) {
    return renderResponse(req, {
      spec: "https://petstore.swagger.io/v2/swagger.json",
      allowCustomQuery: { spec: false, renderer: true },
    });
  },
});

renderHTML

Using renderHTML(options), you can render UI into an HTML string.

import { renderHTML } from "openapi-renderer";

const html = renderHTML({
  spec: "https://petstore.swagger.io/v2/swagger.json",
});
