how to setup nginx reverse proxy for nodejs - node.js

Question

I tried a lot for this, but not working.
help me any one please..
node is at port 3000 and nginx is at 8080 in localhost
this is node index
var express=require('express'),app=express(),cors =require('cors');
app.use(cors({origin: 'http://127.0.0.1:8080'}));
app.get('/home', (req, res) => {res.send("ok");});
app.listen(3000, '127.0.0.1', function(){console.log('listening on port 3000..');});
this is nginx conf
#user nobody;
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
server {
listen 8080;
server_name 127.0.0.1;
location / {
root D:/www;
index index.html index.htm;
}
location /api/ {
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 Host $host;
proxy_cache_bypass $http_upgrade;
}
}
}

HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier).
(XHR)GET - http://127.0.0.1:8080/api/home

Answer 1

server name in nginx conf is not correct. Server names are defined using the server_name directive and determine which server block is used for a given request. They may be defined using exact names, wildcard names, or regular expressions. Replace it with localhost.
