Express：禁用特定路由的标头（Etag、set-cookie 等）

Question

For my application, we have rest API and the webapp server from the same app. (it is small enought not to have separate deployment)

Is there any way I can exclude all /api/* route paths to disable caching and cookies?

Note: I cannot do app.disable('etag') as it will disable for the entire webapp.

Afaik this is currently not possible - also there are a few open issues on github like this one for example: https://github.com/expressjs/express/issues/2472

As a workaround you could remove the headers for requests on the /api -route using something like this:

const onHeaders = require('on-headers')

// mount custom middleware for all api-requests
app.use("/api*", (req, res, next) => {
   removeHeaders(res);
   next();
});

function removeHeaders(res) {
  onHeaders(res, () => {
    res.removeHeader('ETag');
    // remove other headers ...
  });
}
