Nginx re-directions from "www" to "non www" and from "http" to "https"? - nginx

Question

I have my app hosted in the base URL: https://myapp.com/
Now I want to add re-directions from "www" to "non www" / "http" to "https", where:
https://myapp.com/
https://www.myapp.com/
http://myapp.com/
http://www.myapp.com/
Last 3 URLs should 301 redirect to the first one.
Right now second URL is not redirected and the last 2 are redirected using a 307 redirection instead of 301.
Here is my nginx configuration:
server {
listen 80;
server_name myapp.com www.myapp.com;
location / {
return 301 https://$host$request_uri;
}
}
server {
listen 443 ssl;
server_name myapp.com www.myapp.com;
server_tokens off;
ssl_certificate /etc/nginx/conf.d/self-signed-fullchain.pem;
ssl_certificate_key /etc/nginx/conf.d/self-signed-privkey.pem;
include /etc/nginx/conf.d/options-ssl-nginx.conf;
ssl_dhparam /etc/nginx/conf.d/ssl-dhparams.pem;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location ~ ^/(api)/ {
proxy_pass http://myapp:3000;
}
}
So how can I actually do this?

Answer 1

Just add one more server block with server_name www.myapp.com;, and add redirect:
return 301 https://myapp.com$request_uri;
Edit main server block to server_name myapp.com;
Should be something like that:
server {
listen 80;
server_name myapp.com www.myapp.com;
location / {
return 301 https://$host$request_uri;
}
}
server {
listen 443 ssl;
server_name www.myapp.com;
server_tokens off;
ssl_certificate /etc/nginx/conf.d/self-signed-fullchain.pem;
ssl_certificate_key /etc/nginx/conf.d/self-signed-privkey.pem;
include /etc/nginx/conf.d/options-ssl-nginx.conf;
ssl_dhparam /etc/nginx/conf.d/ssl-dhparams.pem;
return 301 https://myapp.com$request_uri;
}
server {
listen 443 ssl;
server_name myapp.com;
server_tokens off;
ssl_certificate /etc/nginx/conf.d/self-signed-fullchain.pem;
ssl_certificate_key /etc/nginx/conf.d/self-signed-privkey.pem;
include /etc/nginx/conf.d/options-ssl-nginx.conf;
ssl_dhparam /etc/nginx/conf.d/ssl-dhparams.pem;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
location ~ ^/(api)/ {
proxy_pass http://myapp:3000;
}
}
