-- These modules are auto-loaded, but should you want
-- to disable them then uncomment them here:
modules_disabled  = {
    -- "offline"; -- Store offline messages
    -- "c2s"; -- Handle client connections
    -- "s2s"; -- Handle server-to-server connections
    -- "posix"; -- POSIX functionality, sends server to background, etc.
}


-- Server-to-server authentication
-- Require valid certificates for server-to-server connections?
-- If false, other methods such as dialback (DNS) may be used instead.

s2s_secure_auth = true

-- Some servers have invalid or self-signed certificates. You can list
-- remote domains here that will not be required to authenticate using
-- certificates. They will be authenticated using other methods instead,
-- even when s2s_secure_auth is enabled.

--s2s_insecure_domains = { "insecure.example" }

-- Even if you disable s2s_secure_auth, you can still require valid
-- certificates for some domains by specifying a list here.

--s2s_secure_domains = { "jabber.org" }


-- Rate limits
-- Enable rate limits for incoming client and server connections. These help
-- protect from excessive resource consumption and denial-of-service attacks.

limits = {
    c2s = {
        rate = "50kb/s",
    },
    s2sin = {
        rate = "300kb/s",
    },
}

-- Authentication
-- Many authentication providers, including the default one, allow you to
-- create user accounts via Prosody's admin interfaces. For details, see the
-- documentation at https://prosody.im/doc/creating_accounts
authentication = "internal_hashed"

-- Storage
-- Select the storage backend to use. By default Prosody uses flat files
-- in its configured data directory, but it also supports more backends
-- through modules. An "sql" backend is included by default, but requires
-- additional dependencies. See https://prosody.im/doc/storage for more info.

storage = "sql" -- Default is "internal"

-- For the "sql" backend, you can uncomment *one* of the below to configure:
sql = { driver = "SQLite3", database = "prosody.sqlite" } -- Default. 'database' is the filename.
--sql = { driver = "MySQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
--sql = { driver = "PostgreSQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }


-- Archiving configuration
-- If mod_mam is enabled, Prosody will store a copy of every message. This
-- is used to synchronize conversations between multiple clients, even if
-- they are offline. This setting controls how long Prosody will keep
-- messages in the archive before removing them.

archive_expires_after = "1w" -- Remove archived messages after 1 week

-- You can also configure messages to be stored in-memory only. For more
-- archiving options, see https://prosody.im/doc/modules/mod_mam


-- Audio/video call relay (STUN/TURN)
-- To ensure clients connected to the server can establish connections for
-- low-latency media streaming (such as audio and video calls), it is
-- recommended to run a STUN/TURN server for clients to use. If you do this,
-- specify the details here so clients can discover it.
-- Find more information at https://prosody.im/doc/turn

-- Specify the address of the TURN service (you may use the same domain as XMPP)
--turn_external_host = "turn.example.com"

-- This secret must be set to the same value in both Prosody and the TURN server
--turn_external_secret = "your-secret-turn-access-token"


-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
log = {
    -- Docker: log to stdout/stderr
    info = "*console";
    error = "*console";
    -- "*syslog"; -- Uncomment to also log to syslog
}


-- statistics = "internal"


-- Certificates
ssl = {
    certificate = "/etc/prosody/certs/certs/" .. xmpp_domain .. ".crt",
    key = "/etc/prosody/certs/private/" .. xmpp_domain .. ".key",
}

-- HTTP file upload (XEP-0363)
http_file_share_size_limit = 10 * 1024 * 1024   -- 10 MB per file
http_file_share_expire_after = 60 * 60 * 24 * 14 -- delete after 14 days
http_external_url = "https://" .. xmpp_domain .. "/"

----------- Virtual hosts -----------
-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
-- Settings under each VirtualHost entry apply *only* to that host.

VirtualHost(xmpp_domain)

------ Components ------
-- You can specify components to add hosts that provide special services,
-- like multi-user conferences, and transports.
-- For more information on components, see https://prosody.im/doc/components

-- Multi-user chat (group chats)
Component("conference." .. xmpp_domain, "muc")
    modules_enabled = { "muc_mam" } -- store group chat history
    -- Default room settings applied to every newly created room
    muc_room_default_public          = true  -- rooms are listed in the room browser
    muc_room_default_persistent      = true  -- rooms survive when the last user leaves
    muc_room_default_members_only    = false -- anyone can join
    muc_room_default_allow_register  = true  -- users can bookmark with a nickname
    muc_room_default_history_length  = 50    -- messages shown on join

---Set up an external component (default component port is 5347)
--
-- External components allow adding various services, such as gateways/
-- bridges to non-XMPP networks and services. For more info
-- see: https://prosody.im/doc/components#adding_an_external_component
--
--Component "gateway.example.com"
--  component_secret = "password"


---------- End of the Prosody Configuration file ----------
-- You usually **DO NOT** want to add settings here at the end, as they would
-- only apply to the last defined VirtualHost or Component.
--
-- Settings for the global section should go higher up, before the first
-- VirtualHost or Component line, while settings intended for specific hosts
-- should go under the corresponding VirtualHost or Component line.
--
-- For more information see https://prosody.im/doc/configure
