Intercept H3 Response Body (Plus Types?)

[tobychidi]

Now, the plugin I want to create requires I append something to the body of the response.

Here is what was done in express. How do I replicate in H3/Nitro

const originalSend = res.send;
res.send = function sendOverWrite(body) {
originalSend.call(this, body);
this._treblleResponsebody = body;
};

Would the render:response hook work for your use-case https://nuxt.com/docs/api/advanced/hooks#nitro-app-hooks-runtime-server-side work for you ?

[tobychidi]

render:response seems to only works for page renders and not for API requests.

I think that your only option is a middleware, altough, they run globally before your logic. We do have some features coming that will enable the ability to run code after an event handler has returned, but in the meantime I also added a proposal that could allow you to do that #1396

However, if you need to do this now, you can do it with a custom nitro preset #1373

You can try with nitro:

export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook("request", (event) => {
    console.log("on request", event.path);
  });

  nitroApp.hooks.hook("beforeResponse", (event, { body }) => {
    send(
      event,
      JSON.stringify({
        status: 200,
        data: body,
      })
    );
  });
});
