How to use

as express middleware

const createIframe = require("node-iframe");

app.use(createIframe);

app.get("/iframe", (req, res) =>
  res.createIframe({
    url: req.query.url,
    baseHref: req.query.baseHref, // optional: determine how to control link redirects,
    config: JSON.parse(req.query.config), // optional: determine element cors or inlining #shape src/iframe.ts#L34
  })
);

On the client use directly in your iframe if your api is on the same server set the url below like this or if your using a framework like gatsby, nextjs, etc or non-express apps

<iframe src="/iframe/?url=https://www.etsy.com" />

You can even fetch the iframe directly by importing fetchFrame on the client or server.

const { fetchFrame } = require("node-iframe");

async function fetchIframe() {
  return await fetchFrame({ url: "https://www.etsy.com" });
}

const {
  configureCacheControl,
  configureResourceControl,
  configureTemplates,
} = require("node-iframe");

// optional: configure if elements should be inlined, cors, etc, this combines with the `config` param
configureResourceControl({
  inline: { script: true, link: false },
  cors: { script: true },
});
// optional: configure cache-control, to disable cache set `disabled` to true - check https://github.com/node-cache/node-cache#options
// for more options and info
configureCacheControl({ stdTTL: 0, checkperiod: 600, disabled: false });
