How to replace such location ( Apache, htaccess, nginx, openLS)?

Decided to migrate to nginx for openLS, and there is as I understand it location does not work, and instead use rewrite in apache, but since I'm not experienced in work with apache could you please tell me what I must take action to understand how to migrate these locations for Apache:

#1
location ~* \\.(?:json)$ {
add_header Access-Control-Allow-Origin *;
}
#2
location / {
try_files $uri $uri/ /index.php?$args;
}
#3
location /uploads/ {
root /var/www/project;
}
