    // - A **public server** does not require authentication. Anyone can connect
    //   to IRC networks in this mode. All IRC connections and channel
    //   scrollbacks are lost when a user leaves the client.
    // - A **private server** requires users to log in. Their IRC connections are
    //   kept even when they are not using or logged in to the client. All joined
    //   channels and scrollbacks are available when they come back.
    //
    // This value is set to `false` by default.

    // ### `host`
    //
    // IP address or hostname for the web server to listen to. For example, set it
    // to `"127.0.0.1"` to accept connections from localhost only.
    //
    // For UNIX domain sockets, use `"unix:/absolute/path/to/file.sock"`.

    // This value is set to `undefined` by default to let the operating system
    // pick its preferred one.
    bind: undefined,
    // ### `reverseProxy`
    //
    // When set to `true`, The Lounge is marked as served behind a reverse proxy
    // and will honor the `X-Forwarded-For` header.
    //
    // This value is set to `false` by default.
    reverseProxy: true,
    // ### `maxHistory`
    //
    // Defines the maximum number of history lines that will be kept in memory per
    // channel/query, in order to reduce the memory usage of the server. Setting
    // this to `-1` will keep unlimited amount.

    // - `enable`: when set to `false`, HTTPS support is disabled
    //    and all other values are ignored.
    // - `key`: Path to the private key file.
    // - `certificate`: Path to the certificate.
    // - `ca`: Path to the CA bundle.

    //
    // Set the default theme to serve to new users. They will be able to select a
    // different one in their client settings among those available.
    //
    // The Lounge ships with two themes (`default` and `morning`) and can be
    // extended by installing more themes. Read more about how to manage them
    // [here](https://thelounge.chat/docs/guides/theme-creation).
    //
    // This value needs to be the package name and not the display name. For
    // example, the value for Morning would be `morning`, and the value for
    // Solarized would be `thelounge-theme-solarized`.
    //
    // This value is set to `"default"` by default.
    theme: "default",
    // ### `prefetch`
    //
    // When set to `true`, The Lounge will load thumbnails and site descriptions
    // from URLs posted in channels and private messages.
    //
    // This value is set to `false` by default.
    prefetch: false,
    // ### `disableMediaPreview`
    //
    // When set to `true`, The Lounge will not preview media (images, video and
    // audio) hosted on third-party sites. This ensures the client does not
    // make any requests to external sites. If `prefetchStorage` is enabled,
    // images proxied via the The Lounge will be previewed.
    //
    // This has no effect if `prefetch` is set to `false`.
    //
    // This value is set to `false` by default.
    disableMediaPreview: false,
    // ### `prefetchStorage`
    // When set to `true`, The Lounge will store and proxy prefetched images and
    // thumbnails on the filesystem rather than directly display the content at
    // the original URLs.
    //
    // This option primarily exists to resolve mixed content warnings by not
    // loading images from http hosts. This option does not work for video
    // or audio as The Lounge will only load these from https hosts.
    //
    // If storage is enabled, The Lounge will fetch and store images and thumbnails
    // in the `${THELOUNGE_HOME}/storage` folder.
    //
    // Images are deleted when they are no longer referenced by any message
    // (controlled by `maxHistory`), and the folder is cleaned up when The Lounge
    // restarts.
    //
    // This value is set to `false` by default.
    prefetchStorage: false,
    // ### `prefetchMaxImageSize`
    //
    // When `prefetch` is enabled, images will only be displayed if their file
    // size does not exceed this limit.
    //
    // This value is set to `2048` kilobytes by default.
    prefetchMaxImageSize: 2048,
    // ### prefetchMaxSearchSize
    //
    // This value sets the maximum response size allowed when finding the Open
    // Graph tags for link previews. The entire response is temporarily stored
    // in memory and for some sites like YouTube this can easily exceed 300
    // kilobytes.
    //
    // This value is set to `50` kilobytes by default.
    prefetchMaxSearchSize: 50,
    // ### `prefetchTimeout`
    //
    // When `prefetch` is enabled, this value sets the number of milliseconds
    // before The Lounge gives up attempting to fetch a link. This can be useful
    // if you've increased the `prefetchMaxImageSize`.
    //
    // Take caution, however, that an inordinately large value may lead to
    // performance issues or even a denial of service, since The Lounge will not
    // be able to clean up outgoing connections as quickly. Usually the default
    // value is appropriate, so only change it if necessary.
    //
    // This value is set to `5000` milliseconds by default.
    prefetchTimeout: 5000,
    // ### `fileUpload`
    //
    // Allow uploading files to the server hosting The Lounge.
    //
    // Files are stored in the `${THELOUNGE_HOME}/uploads` folder, do not expire,
    // and are not removed by The Lounge. This may cause issues depending on your
    // hardware, for example in terms of disk usage.
    //
    // The available keys for the `fileUpload` object are:
    //
    // - `enable`: When set to `true`, files can be uploaded on the client with a
    //   drag-and-drop or using the upload dialog.
    // - `maxFileSize`: When file upload is enabled, users sending files above
    //   this limit will be prompted with an error message in their browser. A value of
    //   `-1` disables the file size limit and allows files of any size. **Use at
    //   your own risk.** This value is set to `10240` kilobytes by default.
    // - `baseUrl`: If you want to change the URL where uploaded files are accessed,
    //   you can set this option to `"https://example.com/folder/"` and the final URL
    //   would look like `"https://example.com/folder/aabbccddeeff1234/name.png"`.
    //   If you use this option, you must have a reverse proxy configured,
    //   to correctly proxy the uploads URLs back to The Lounge.
    //   This value is set to `null` by default.
    fileUpload: {
        enable: false,
        maxFileSize: 10240,

    // This value is set to `["polling", "websocket"]` by default.
    transports: ["polling", "websocket"],
    // ### `leaveMessage`
    //
    // Set users' default `quit` and `part` messages if they are not providing
    // one.
    //
    // This value is set to `"The Lounge - https://thelounge.chat"` by
    // default.
    leaveMessage: "Buzz...",
    // ## Default network
    // ### `defaults`
    //
    // Specifies default network information that will be used as placeholder
    // values in the *Connect* window.
    //
    // The available keys for the `defaults` object are:
    //
    // - `name`: Name to display in the channel list of The Lounge. This value is
    //   not forwarded to the IRC network.
    // - `host`: IP address or hostname of the IRC server.
    // - `port`: Usually 6667 for unencrypted connections and 6697 for
    //   connections encrypted with TLS.
    // - `password`: Connection password. If the server supports SASL capability,
    //   then this password will be used in SASL authentication.
    // - `tls`: Enable TLS connections
    // - `rejectUnauthorized`: Whether the server certificate should be verified
    //   against the list of supplied Certificate Authorities (CAs) by your
    //   Node.js installation.
    // - `nick`: Nick name. Percent signs (`%`) will be replaced by random
    //   numbers from 0 to 9. For example, `Guest%%%` may become `Guest123`.
    // - `username`: User name.
    // - `realname`: Real name displayed by some clients. Defaults to the nick if set to ""
    // - `leaveMessage`: Network specific leave message (overrides global leaveMessage)
    // - `join`: Comma-separated list of channels to auto-join once connected.
    //
    // This value is set to connect to the official channel of The Lounge on
    // Libera.Chat by default:
    //
    // ```js
    // defaults: {
    //   name: "Libera.Chat",
    //   host: "irc.libera.chat",
    //   port: 6697,

        host: "irc.secretbee.buzz",
        port: 6697,
        password: "",
        tls: true,
        rejectUnauthorized: true,
        nick: "bee%%",
        username: "bee",
        realname: "",
        join: "#thehive",
        leaveMessage: "",
    },
    // ### `lockNetwork`
    //
    // When set to `true`, users will not be able to modify host, port and TLS
    // settings and will be limited to the configured network.
    // These fields will also be hidden from the UI.
    //
    // This value is set to `false` by default.
    lockNetwork: true,
    // ## User management
    // ### `messageStorage`
    // The Lounge can log user messages, for example to access them later or to
    // reload messages on server restart.
    // Set this array with one or multiple values to enable logging:
    // - `text`: Messages per network and channel will be stored as text files.
    //   **Messages will not be reloaded on restart.**
    // - `sqlite`: Messages are stored in SQLite database files, one per user.
    //
    // Logging can be disabled globally by setting this value to an empty array
    // `[]`. Logging is also controlled per user individually in the `log` key of
    // their JSON configuration file.
    //
    // This value is set to `["sqlite", "text"]` by default.
    messageStorage: ["sqlite", "text"],
    // ### `storagePolicy`
    // When the sqlite storage is in use, control the maximum storage duration.
    // A background task will periodically clean up messages older than the limit.
    // The available keys for the `storagePolicy` object are:
    //
    // - `enabled`: If this is false, the cleaning task is not running.
    // - `maxAgeDays`: Maximum age of an entry in days.
    // - `deletionPolicy`: Controls what types of messages are being deleted.
    //   Valid options are:
    //   - `statusOnly`: Only delete message types which are status related (e.g. away, back, join, parts, mode, ctcp...)
    //     but keep actual messages from nicks. This keeps the DB size down while retaining "precious" messages.
    //   - `everything`: Delete everything, including messages from irc nicks
    storagePolicy: {
        enabled: false,
        maxAgeDays: 7,
        deletionPolicy: "statusOnly",
    },
    // ### `useHexIp`
    //
    // When set to `true`, users' IP addresses will be encoded as hex.
    //
    // This is done to share the real user IP address with the server for host
    // masking purposes. This is encoded in the `username` field and only supports
    // IPv4.
    //
    // This value is set to `false` by default.
    useHexIp: true,
    // ## WEBIRC support
    //
    // When enabled, The Lounge will pass the connecting user's host and IP to the
    // IRC server. Note that this requires to obtain a password from the IRC
    // network that The Lounge will be connecting to and generally involves a lot
    // of trust from the network you are connecting to.
    //
    // There are 2 ways to configure the `webirc` setting:
    //
    // - **Basic**: an object where keys are IRC hosts and values are passwords.
    //   For example:
    //
    //   ```json
    //   webirc: {
    //     "irc.example.net": "thisiswebircpassword1",
    //     "irc.example.org": "thisiswebircpassword2",
    //   },
    //   ```
    //
    // - **Advanced**: an object where keys are IRC hosts and values are functions
    //   that take two arguments (`webircObj`, `network`) and return an
    //   object to be directly passed to `irc-framework`. `webircObj` contains the
    //   generated object which you can modify. For example:
    //
    //   ```js
    //   webirc: {
    //     "irc.example.com": (webircObj, network) => {
    //       webircObj.password = "thisiswebircpassword";
    //       webircObj.hostname = `webirc/${webircObj.hostname}`;
    //       return webircObj;
    //     },
    //   },
    //   ```
    //
    // This value is set to `null` to disable WEBIRC by default.
    webirc: null,
    // ## identd and oidentd support
    // ### `identd`
    //
    // Run The Lounge with `identd` support.
    //
    // The available keys for the `identd` object are:
    //
    // - `enable`: When `true`, the identd daemon runs on server start.
    // - `port`: Port to listen for ident requests.
    //
    // The value of `enable` is set to `false` to disable `identd` support by
    // default, in which case the value of `port` is ignored. The default value of
    // `port` is 113.
    identd: {
        enable: false,
        port: 113,
    },
    // ### `oidentd`
    //
    // When this setting is a string, this enables `oidentd` support using the
    // configuration file located at the given path.
    //
    // This is set to `null` by default to disable `oidentd` support.
    oidentd: null,
    // ## LDAP support
    // These settings enable and configure LDAP authentication.
    //
    // They are only being used in private mode. To know more about private mode,
    // see the `public` setting above.
    //
    // The authentication process works as follows:
    //
    // 1. The Lounge connects to the LDAP server with its system credentials.
    // 2. It performs an LDAP search query to find the full DN associated to the
    //    user requesting to log in.
    // 3. The Lounge tries to connect a second time, but this time using the
    //    user's DN and password. Authentication is validated if and only if this
    //    connection is successful.
    //
    // The search query takes a couple of parameters in `searchDN`:
    //
    // - a base DN `searchDN/base`. Only children nodes of this DN will likely
    //   be returned;
    // - a search scope `searchDN/scope` (see LDAP documentation);
    // - the query itself, built as `(&(<primaryKey>=<username>) <filter>)`
    //   where `<username>` is the user name provided in the log in request,
    //   `<primaryKey>` is provided by the config and `<filter>` is a filtering
    //   complement also given in the config, to filter for instance only for
    //   nodes of type `inetOrgPerson`, or whatever LDAP search allows.
    //
    // Alternatively, you can specify the `bindDN` parameter. This will make The
    // Lounge ignore `searchDN` options and assume that the user DN is always
    // `<bindDN>,<primaryKey>=<username>`, where `<username>` is the user name
    // provided in the log in request, and `<bindDN>` and `<primaryKey>` are
    // provided by the configuration.
    //
    // The available keys for the `ldap` object are:
    ldap: {
        // - `enable`: when set to `false`, LDAP support is disabled and all other
        //   values are ignored.
        enable: false,
        // - `url`: A url of the form `ldaps://<ip>:<port>`.
        //   For plain connections, use the `ldap` scheme.
        url: "ldaps://example.com",
        // - `tlsOptions`: LDAP connection TLS options (only used if scheme is
        //   `ldaps://`). It is an object whose values are Node.js' `tls.connect()`
        //   options. It is set to `{}` by default.
        //   For example, this option can be used in order to force the use of IPv6:
        //   ```js
        //   {
        //     host: 'my::ip::v6',
        //     servername: 'example.com'
        //   }
        //   ```
        tlsOptions: {},
        // - `primaryKey`: LDAP primary key. It is set to `"uid"` by default.
        primaryKey: "uid",
        // - `baseDN`: LDAP base DN, alternative to `searchDN`. For example, set it
        //   to `"ou=accounts,dc=example,dc=com"`.
        //   When unset, the LDAP auth logic with use `searchDN` instead to locate users.
        // - `searchDN`: LDAP search DN settings. This defines the procedure by
        //   which The Lounge first looks for the user DN before authenticating them.
        //   It is ignored if `baseDN` is specified. It is an object with the
        //   following keys:
        searchDN: {
            //   - `rootDN`: This bind DN is used to query the server for the DN of
            //     the user. This is supposed to be a system user that has access in
            //     read-only to the DNs of the people that are allowed to log in.
            //     It is set to `"cn=thelounge,ou=system-users,dc=example,dc=com"` by
            //     default.
            rootDN: "cn=thelounge,ou=system-users,dc=example,dc=com",
            //   - `rootPassword`: Password of The Lounge LDAP system user.
            rootPassword: "1234",
            //   - `filter`: it is set to `"(&(objectClass=person)(memberOf=ou=accounts,dc=example,dc=com))"`
            //     by default.
            filter: "(&(objectClass=person)(memberOf=ou=accounts,dc=example,dc=com))",
            //   - `base`: LDAP search base (search only within this node). It is set
            //     to `"dc=example,dc=com"` by default.
            base: "dc=example,dc=com",

    // ## Debugging settings
    // The `debug` object contains several settings to enable debugging in The
    // Lounge. Use them to learn more about an issue you are noticing but be aware
    // this may produce more logging or may affect connection performance so it is
    // not recommended to use them by default.
