File server app let you expose any folder in your localhost machine to the internet, for example:
# *nix based loclx tunnel http --file-server /home/shared # windows loclx tunnel http --file-server C:\Users\ali\shared
This will serve the files in the
shared directory to be accessible through the internet, also you can use any middleware beside the file server app for example to protect this file server with basic authentication so only known users can access the created shared folder, you can run:
loclx tunnel http --file-server /home/shared --basic-auth user:pass
