If you're dealing with multiple APIs and multiple OpenAPI files, the API Catalog comes in handy. It
creates an overview of all your APIs and lets you organize them into categories and tags.
Enable API Catalog 
The first step to enable the API Catalog, you need to add a catalogs object to your Zudoku
configuration file.
Javascript zudoku.config.ts
const  config  =  {   // ...   catalogs: {     path:  "/catalog" ,     label:  "API Catalog" ,   },   // ... }; 
You can then add your APIs to the catalog by adding the categories property to your API
configuration.
Javascript zudoku.config.ts
const  config  =  {   // ...   apis: [     // ...     {       type:  "file" ,       input:  "./operational.json" ,       path:  "/api-operational" ,       categories: [{ label:  "General" , tags: [ "Operational" ] }],     },     {       type:  "file" ,       input:  "./enduser.json" ,       path:  "/api-enduser" ,       categories: [{ label:  "General" , tags: [ "End-User" ] }],     },     {       type:  "file" ,       input:  "./openapi.json" ,       path:  "/api-auth" ,       categories: [{ label:  "Other" , tags: [ "Authentication" ] }],     },     // ...   ],   // ... }; 
Advanced Configuration 
Select APIs to show in the catalog 
You can select which APIs are shown in the catalog by using the items property. The items
property is an array of navigation IDs of the APIs you want to show in the catalog.
Javascript zudoku.config.ts
const  config  =  {   // ...   catalogs: {     path:  "/catalog" ,     label:  "API Catalog" ,     // Only show the operational API in the catalog     items: [ "api-operational" ],   },   apis: [     // ...     {       type:  "file" ,       input:  "./operational.json" ,       path:  "/api-operational" ,       categories: [{ label:  "General" , tags: [ "Operational" ] }],     },     {       type:  "file" ,       input:  "./enduser.json" ,       path:  "/api-enduser" ,       categories: [{ label:  "General" , tags: [ "End-User" ] }],     },   ],   // ... }; 
Filtering catalog items 
You can filter which APIs are shown in the catalog by using the filterItems property. The function
receives the items and context as arguments.
Javascript zudoku.config.ts
const  config  =  {   // ...   catalogs: {     path:  "/catalog" ,     label:  "API Catalog" ,     filterItems : ( items , {  auth :  AuthState  })  =>  {       return  items. filter (( items )  =>  items.tags. includes (auth));     },   },   // ... };
