TL;DR
const { createProxyMiddleware, responseInterceptor } = require('http-proxy-middleware');
const proxy = createProxyMiddleware({
/**
* IMPORTANT: avoid res.end being called automatically
**/
selfHandleResponse: true, // res.end() will be called internally by responseInterceptor()
/**
* Intercept response and replace 'Hello' with 'Goodbye'
**/
onProxyRes: responseInterceptor(async (responseBuffer, proxyRes, req, res) => {
const response = responseBuffer.toString('utf-8'); // convert buffer to string
return response.replace('Hello', 'Goodbye'); // manipulate response and return the result
}),
