If you can specify the location as a prefix location, you can use the proxy_pass directive to modify the URI:

location /app/ {
    proxy_pass http://dev/abc/;
    ...
}

See this document for details.

Alternatively, you can rewrite the URI using the break modifier:

location ~ ^/app/. {
    rewrite ^/app(.*)$ /abc$1 break;
    proxy_pass http://dev;
    ...
}

See this document for details.
