</head>| Library | Required | Description |
|---|---|---|
| Tailwind CSS | YES | helps you to rapidly build modern websites without ever leaving your HTML. A utility-first CSS framework packed with classes like flex, pt-4, text-center and rotate-90 that can be composed to build any design, directly in your markup. |
| Font-Awesome | NO* | The easiest way to get icons on your website is with a Kit. It's your very own custom version of Font Awesome, all bundled up with only the icons, tools, and settings you need. |
| JsonEditor | NO | is a web-based tool to view, edit, format, and validate JSON. It has various modes such as a tree editor, a code editor, and a plain text editor. The editor can be used as a component in your own web application. The library can be loaded as CommonJS module, AMD module, or as a regular javascript file. |
(*): Font-Awesome library is not required but used by some components. If it is not loaded, the icon would be missing.

};Data Structure Properties
- name: display name of the cluster
- version: cluster version
- resources: If all/majority of nodes have the same hardware (cpu/memory) you can fill the resources at the cluster level instead of individual nodes.
{
memory: "128",
cpus: "8"
}
- serverGroups: Array of Server Groups. Each Server Group contains the information of the Server Group name, list of nodes and status.

]- buckets: Array of Buckets. You can define
ephemeral,couchbaseandmagmabucket types. The default value iftypeproperty is missing iscouchbase. Optionally, you can display the list of scopes and collections per scope. Another optional property among others, isconnectorsthat would accept the following enum values:mobile,kafka,elastic,spark

9 Nodes distributed accross 3 Server Group And non homogenous cpu/memory resources
mobile - 2 Sync Gateway Groups, 3 data and 2 query/index nodes
mobile - 2 Clients Couchbase Lite languages, 2 groups of 5 Sync Gateways and 3 server groups
