Handling large header

[arnabk]

We have an unusual situation where we ended up having a large number of headers in a request. Generally by using NODE_OPTIONS=--max-http-header-size we could get around this problem, however graphql-mesh uses uNetworking/uWebSockets for network calls. By setting UWS_HTTP_MAX_HEADERS_SIZE I was able to get around the problem of 431 HTTP status error, however the requests are timing out with UWS_HTTP_MAX_HEADERS_SIZE=11630.

If I reduce the header size everything works fine.

Any suggestions on where I should be looking at to get around this problem. Is it possible to chose a different library instead of uNetworking/uWebSockets to be used in mesh (probably expressjs) ?

For those coming to this if you want to get around it, use expressJS and wrap graphql-mesh handler. Here is an example that worked for me.

import express from 'express';
import { createBuiltMeshHTTPHandler } from '../.mesh';

const app = express();
const port = process.env.PORT || 4001;

app.use('*', createBuiltMeshHTTPHandler());

app.listen(port, () => {
  console.log(`Example app listening on port ${port}`)
});

process.on('SIGINT', () => {
  console.log("Caught interrupt signal");
  process.exit();
});
