    // The following property can be used to enable HTTPS
    // See http://nodejs.org/api/https.html#https_https_createserver_options_requestlistener
    // for details on its contents.
    // This property can be either an object, containing both a (private) key and a (public) certificate,
    // or a function that returns such an object:
    //// https object:
    //https: {
    //  key: require("fs").readFileSync('privkey.pem'),
    //  cert: require("fs").readFileSync('cert.pem')
    //},

    // regular time interval in hours.
    // This requires:
    //   - the `https` setting to be a function that can be called to get
    //     the refreshed settings.
    //   - Node.js 11 or later.
    //httpsRefreshInterval : 12,

    // The following property can be used to cause insecure HTTP connections to
    // be redirected to HTTPS.
    //requireHttps: true,

    // The following property can be used to disable the editor. The admin API
    // is not affected by this option. To disable both the editor and the admin
    // API, use either the httpRoot or httpAdminRoot properties
    //disableEditor: false,

    // The following property can be used to configure cross-origin resource sharing
    // in the HTTP nodes.
    // See https://github.com/troygoode/node-cors#configuration-options for
    // details on its contents. The following is a basic permissive set of options:
    //httpNodeCors: {
    //    origin: "*",
    //    methods: "GET,PUT,POST,DELETE"
    //},

    // If you need to set an http proxy please set an environment variable
    // called http_proxy (or HTTP_PROXY) outside of Node-RED in the operating system.
    // For example - http_proxy=http://myproxy.com:8080
    // (Setting it here will have no effect)
    // You may also specify no_proxy (or NO_PROXY) to supply a comma separated
    // list of domains to not proxy, eg - no_proxy=.acme.co,.acme.co.uk

    // The following property can be used to add a custom middleware function
    // in front of all http in nodes. This allows custom authentication to be
    // applied to all http in nodes, or any other sort of common request processing.
    //httpNodeMiddleware: function(req,res,next) {
    //    // Handle/reject the request, or pass it on to the http in node by calling next();
    //    // Optionally skip our rawBodyParser by setting this to true;
    //    //req.skipRawBodyParser = true;
    //    next();
    //},


    // The following property can be used to add a custom middleware function
    // in front of all admin http routes. For example, to set custom http
    // headers
    // httpAdminMiddleware: function(req,res,next) {
    //    // Set the X-Frame-Options header to limit where the editor
    //    // can be embedded
    //    //res.set('X-Frame-Options', 'sameorigin');
    //    next();
    // },

    // The following property can be used to pass custom options to the Express.js
    // server used by Node-RED. For a full list of available options, refer
    // to http://expressjs.com/en/api.html#app.settings.table
    //httpServerOptions: { },

    // The following property can be used to verify websocket connection attempts.
    // This allows, for example, the HTTP request headers to be checked to ensure
    // they include valid authentication information.
    //webSocketNodeVerifyClient: function(info) {
    //    // 'info' has three properties:
    //    //   - origin : the value in the Origin header
    //    //   - req : the HTTP request
    //    //   - secure : true if req.connection.authorized or req.connection.encrypted is set
    //    //
    //    // The function should return true if the connection should be accepted, false otherwise.
    //    //
    //    // Alternatively, if this function is defined to accept a second argument, callback,
    //    // it can be used to verify the client asynchronously.
    //    // The callback takes three arguments:
    //    //   - result : boolean, whether to accept the connection or not
    //    //   - code : if result is false, the HTTP error status to return
    //    //   - reason: if result is false, the HTTP reason string to return
    //},

    // The following property can be used to seed Global Context with predefined
    // values. This allows extra node modules to be made available with the
    // Function node.
    // For example,
    //    functionGlobalContext: { os:require('os') }
    // can be accessed in a function block as:
    //    global.get("os")

    valueConvert: '%%valueConvert%%',

        // j5board:require("johnny-five").Board({repl:false})
    },
    // `global.keys()` returns a list of all properties set in global context.
    // This allows them to be displayed in the Context Sidebar within the editor.
    // In some circumstances it is not desirable to expose them to the editor. The
    // following property can be used to hide any property set in `functionGlobalContext`
    // from being list by `global.keys()`.
    // By default, the property is set to false to avoid accidental exposure of
    // their values. Setting this to true will cause the keys to be listed.
    exportGlobalContextKeys: false,


    // Context Storage
    // The following property can be used to enable context storage. The configuration
    // provided here will enable file-based context that flushes to disk every 30 seconds.
    // Refer to the documentation for further options: https://nodered.org/docs/api/context/
    //
    //contextStorage: {
    //    default: {
    //        module:"localfilesystem"
    //    },

    // The following property can be used to order the categories in the editor
    // palette. If a node's category is not in the list, the category will get
    // added to the end of the palette.
    // If not set, the following default order is used:
    //paletteCategories: ['subflows', 'common', 'function', 'network', 'sequence', 'parser', 'storage'],
