### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".
### If the app provides an internal web server (or uses another application server such as uwsgi), the final path should be "/opt/yunohost/$app"

# INSTALL DEPENDENCIES
#=================================================

ynh_print_info "Installing dependencies..."

### `ynh_install_app_dependencies` allows you to add any "apt" dependencies to the package.
### Those deb packages will be installed as dependencies of this package.
### If you're not using this helper:
###		- Remove the section "REMOVE DEPENDENCIES" in the remove script
###		- As well as the section "REINSTALL DEPENDENCIES" in the restore script
###		- And the section "UPGRADE DEPENDENCIES" in the upgrade script

# CREATE A MYSQL DATABASE
#=================================================
ynh_print_info "Creating a MySQL database..."

### Use these lines if you need a database for the application.
### `ynh_mysql_setup_db` will create a database, an associated user and a ramdom password.
### The password will be stored as 'mysqlpwd' into the app settings,
### and will be available as $db_pwd
### If you're not using these lines:
###		- Remove the section "BACKUP THE MYSQL DATABASE" in the backup script
###		- Remove also the section "REMOVE THE MYSQL DATABASE" in the remove script
###		- As well as the section "RESTORE THE MYSQL DATABASE" in the restore script

# STORE THE CONFIG FILE CHECKSUM
#=================================================

### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.

# Calculate and store the config file checksum into the app settings

# SECURE FILES AND DIRECTORIES

### For security reason, any app should set the permissions to root: before anything else.
### Then, if write authorization is needed, any access should be given only to directories
### that really need such authorization.
