Handle Express Subdomain with nginx - node.js

Question

I Wonder how can i handle subdomains in my project that based on Expressjs.
Here's My nginx configuration
server {
listen 80;
server_name bee.local;
access_log /var/log/nginx/bee.local.access.log;
error_log /var/log/nginx/bee.local.error.log;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header X-Forwarded-For $remote_addr;
}
}
server {
listen 80;
server_name api.bee.local;
access_log /var/log/nginx/bee.local.access.log;
error_log /var/log/nginx/bee.local.error.log;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header X-Forwarded-For $remote_addr;
}
}
and here's my router with subdomain support
router.get('/v1/', function(req, res, next) {
res.status(200).json({ title: "title" });
});
app.use(subdomain('api', router));
The problem is that it's rendering the index route
and for sure i setuped the hosts file
I've been searching for 3 hrs can you help me :)

There are several requirements:
Setup Host header in nginx with required domain or proxy if applicable
Use subdomain middleware before other middlewares that handle endpoints
Work example:
nginx configuration:
server {
listen 80;
server_name bee.local;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
server {
listen 80;
server_name api.bee.local;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
nginx configuration with hardcoded Host header values:
I believe that you did not setup Host header correctly. please try next configuration
server {
listen 80;
server_name bee.local;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
# proxy_set_header Host $host;
proxy_set_header Host bee.local;
}
}
server {
listen 80;
server_name api.bee.local;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
# proxy_set_header Host $host;
proxy_set_header Host api.bee.local;
}
}
express app:
var subdomain = require('express-subdomain');
var express = require('express');
var app = express();
var router = express.Router();
router.get('/', function(req, res) {
res.send('Welcome to our API!');
});
router.get('/users', function(req, res) {
res.json([
{ name: "Brian" }
]);
});
app.use(subdomain('api', router));
app.get('/', function(req, res) {
res.send('Homepage');
});
app.listen(3000);
