expressjsHow can I configure Express.js to use Nginx as a reverse proxy?
To configure Express.js to use Nginx as a reverse proxy, you need to set up Nginx as a reverse proxy server and configure it to forward requests to your Express.js application.
First, install Nginx and configure it as a reverse proxy server. In its configuration file, add the following code block:
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://localhost:3000;
}
}
This will tell Nginx to listen on port 80 and forward all requests to example.com
to localhost:3000
, where your Express.js application is running.
Next, in your Express.js application, set the trust proxy
setting to true
to tell Express.js that it is running behind a reverse proxy.
app.set('trust proxy', true);
Finally, make sure that your application is running on localhost:3000
and restart Nginx.
