I've tried to setup proxy like it described in CRA documentation (via http-proxy-middlware).
And all requests to proxied endpoints returns 403 FORBIDDEN
Context info
My app created from template
npx create-react-app pwa-react-typescript --template cra-template-pwa-typescript

const { createProxyMiddleware } = require('express-http-proxy');
const morgan = require('morgan');
module.exports = function (app) {
app.use(
'/backend',
createProxyMiddleware({
target: 'http://localhost:8080',
changeOrigin: true,
}),
);
app.use(morgan('combined')); // just for debug, logging all requests
};
axios instanse
export const axiosInstance = axios.create({
baseURL: '/backend',
timeout: 30000,
});
Problem description
All requests to endpoints starts from localhost:3000/backend are rejected with error 403 FORBIDDEN. Also this requests don't logged in console by morgan, unlike all other requests.
How to solve
Problem was solved with another proxy package – express-http-proxy, and now my setupProxy.js looks like this:
const proxy = require('express-http-proxy');
const morgan = require('morgan');
module.exports = function (app) {
app.use(
'/backend',
proxy('http://localhost:8080'),
);
app.use(morgan('combined'));
};
But I still can't understand, what's wrong with official documented way to setup proxy via http-proxy-middlware. Maybe someone has already faced this problem?
Also tried to setup proxy for all requests in package.json, with proxy field:
"proxy": "http://localhost:8080"
But result was the same – 403 FORBIDDEN

I'm running into an issue to deploy a nuxt-app with some serverMiddleware code on Heroku.
this is my middleware code which just launch an express app:
api/index.js
var express = require("express");
var nodemailer = require("nodemailer");
var app = express();
app.use(express.json());
app.use(
express.urlencoded({
extended: true
})
);
app.get("/", (req, res) => {
res.send("hello world");
});
app.post("/contact", async (req, res) => {
// let testAccount = await nodemailer.createTestAccount();
// create reusable transporter object using the default SMTP transport
let transporter = nodemailer.createTransport({
host: "mail.exemple.net",
port: 587,
secure: false,
auth: {
user: process.env.EMAIL_USERNAME,
pass: process.env.EMAIL_PASSWORD
}
});
// send mail with defined transport object
let info = await transporter.sendMail({
from: req.body.email,
to: "contact#email.com",
subject: "new contact",
text: req.body.message
});
res.end();
});
app.listen(process.env.PORT);
module.exports = {
path: "/api",
handler: app
};
then i registered this file into nuxt.config.js:
serverMiddleware: ["~/api/index"],
the api works perfectly in dev mode (locally).
I first deployed on heroku with the nuxt target setting set to static,
the static content was working perfectly but none of the serverMiddleware code was working (that make senses ^^).
then i switched to target: 'server' but now when i deploy i get this message from heroku:
✖ Nuxt Fatal Error
Error: Address `0.0.0.0:41828` is already in use
i'm sure that i'm missing something but can't find the solution.
just to complete my post i added this line into the package.json file:
"heroku-postbuild": "nuxt build"
and also a Procfile at the root of my app which contain:
web: nuxt start
and finally these are my heroku:config settings:
heroku config:set NPM_CONFIG_PRODUCTION=false
heroku config:set HOST=0.0.0.0
heroku config:set NODE_ENV=production
Any advice on the correct way to deploy much appreciated.
I thought this would be a simple task, but I struggle to find a way to force my webpage to use https.
The next.js webapp lives on the heroku servers and I've set up the SSL. Both https and http version works, but how to I force or redirect the website to use the https version.
I've seen some solution using express, but nothing in my webapp are using express, is it required?
Thanks.
As of Nextjs v12, you can use middleware instead of a setting up a custom server.
Middleware is a better solution for the following reasons:
a custom server often requires additional dependencies (like express)
you give up some of the box features like automatic static optimization
Middleware can be scope to specific paths using the built in routing paradigm
Create a /pages/_middleware.ts (or .js) file with something similar to this:
import { NextFetchEvent, NextRequest, NextResponse } from 'next/server'
type Environment = "production" | "development" | "other";
export function middleware(req: NextRequest, ev: NextFetchEvent) {
const currentEnv = process.env.NODE_ENV as Environment;
if (currentEnv === 'production' &&
req.headers.get("x-forwarded-proto") !== "https") {
return NextResponse.redirect(
`https://${req.headers.get('host')}${req.nextUrl.pathname}`,
301
);
}
return NextResponse.next();
}
I also created an npm package for this.
import sslRedirect from 'next-ssl-redirect-middleware';
export default sslRedirect({});
There is a solution with an NPM library called heroku-ssl-redirect.
First off, install the library using npm i heroku-ssl-redirect.
Then, create a new server.js file with the following script.
const next = require('next');
const express = require('express');
const sslRedirect = require('heroku-ssl-redirect').default; // to make it work with 'require' keyword.
const PORT = process.env.PORT || 3000;
const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });
const handle = app.getRequestHandler();
app.prepare().then(() => {
const server = express();
// Express's middleware to automatically redirect to 'https'.
server.use(sslRedirect());
server.all('*', (req, res) => {
return handle(req, res);
});
server.listen(port, err => {
if (err) throw err;
console.log(`Server starts on ${PORT}.`);
});
});
Then, change the start script to be like this:
"scripts": {
"dev": "next",
"build": "next build",
"start": "node server.js"
}
It should work.
Note that you could replace Express with the createServer method from native Node.js's http module. But I do this with Express to simplify the syntax.

I'm trying to mock API calls from Detox tests and nothing seems to be working. Nock in theory would do exactly what I want but there when I run my tests with nock debugging it isn't seeing any of the requests being made from my app. I'm using axios to make requests and I've tried setting the adapter on my axios instance to the http adapter.
Any suggestions on how to get nock working with Detox or if there is another mocking library you have had success with is appreciated, thanks!
What I ended up doing was leveraging the mocking specified in Detox docs (a separate *.e2e.js file hitting a different endpoint during tests). You define these special files that only run during e2e, I've set mine up to only hit localhost:9091 -- I then run an Express server on that port serving the endpoints I need.
Maybe an ugly way to do it, would love suggestions!
My mock file:
// src/helpers/axios.e2e.js
import axios from 'axios';
const instance = axios.create({
baseURL: `http://localhost:9091/api`,
});
export default instance;
Here's how I am running an express server during tests:
// e2e/mytest.e2e.js
const express = require('express');
let server;
beforeAll(async () => {
const app = express();
app.post('/api/users/register/', (req, res) => {
res.status(400)
res.send({"email": ["Test error: Email is required!"]})
})
await new Promise(function(resolve) {
server = app.listen(9091, "127.0.0.1", function() {
console.log(` Running server on '${JSON.stringify(server.address())}'...`);
resolve();
});
});
})
afterAll(() => {
server.close()
})
I am deploying an Apollo Server for my database to heroku and it is giving an application error. It is not simply show that there is a problem with the get route, it says that the application has an error and the error logs say that the app is crashing. It runs fine locally.
I have set up the procfile with: web: node app.js .
I have tried it with the procfile removed.
I have set playground and introspection to true. I saw that that could be the problem but it did not seem to help.
The port is set to process.env.PORT || 8080 .
Here is the minimal code:
const { ApolloServer } = require('apollo-server-express');
const express = require('express');
const db = require('./models');
const typeDefs = require('./data/schema');
const resolvers = require('./data/resolvers');
const app = express();
const server = new ApolloServer({
typeDefs,
resolvers,
context: { db },
introspection: true,
playground: true,
});
server.applyMiddleware({ app });
const PORT = process.env.PORT || 8080;
app.get('/', (req, res) => {
res.send('hello');
});
app.listen(PORT, () => {
console.log(`Server is ready at ${PORT}`);
});
I am also using some other functions (trying to set up a cron process), but those are commented out.
I would expect to get the / get route to at least say hello, or for the /graphql route to display playground. I am getting neither of those options.
It turns out that I needed to add the following to package.json:
"scripts": {
"start": "app.js",
...
}
And I needed to install packages listed in the heroku logs --tail, but I have had those errors before. Writing the script start key into the package.json file is for when you are deploying your server independently of your react (or client) side.
I've added an expressJS app inside my ember app so I can provide a backend API for my ember app.
My process:
npm install express --save
I created a folder called "server" in the route of my ember application and inside that a file called "server.js".
Yesterday I had it working fine, I already had my ember app running via ember s and tested out the express app using nodemon server/server.js and checking the endpoints I created with Postman.
However this morning when I've tried to run ember s I'm given the following error:
C:\Sandbox\tsodash>ember s
version: 2.3.0-beta.2
Cannot find module 'C:\Sandbox\tsodash\server'

Naturally I assumed I just needed to use modules.exports = function(){ //..expressjs code}
Full Code
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var request = require('request');
var btoa = require('btoa');
var config = require('./config');
var _ = require('lodash');
module.exports = function(){
var endPoints = config.endPoints;
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(bodyParser.json());
var port = process.env.PORT || 4200;
var router = express.Router();
// middleware to use for all requests
router.use(function (req, res, next) {
// do logging
console.log('Something is happening.');
next(); // make sure we go to the next routes and don't stop here
});
router.get('/', function (req, res) {
res.json({
message: 'TSO Git Dash'
});
});
// ..
app.use('/api', router);
app.listen(port);
console.log('Magic happens on port: ' + port);
}
Still no avail.
Folder structure:
Any ideas? I'm assuming it's something simple that I've missed. But I'm stumped.
As #locks suggested in the comments, there is an express server used in mocks and fixtures. The fix was simple, I renamed the folder and the JS file to "api" and ran ember s and it worked perfectly. It seems to have been a naming conflict.
