Sidebar Items 
To automatically generate sidebar items, you can use the useSidebar function. Configure your .vitepress/config.js as follows:
ts
import { useSidebar, useOpenapi } from 'vitepress-openapi'
import spec from '../public/openapi.json' assert { type: 'json' }
const sidebar = useSidebar({ 
    spec,
    // Optionally, you can specify a link prefix for all generated sidebar items.
    linkPrefix: '/operations/',
})
module.exports = {
    // ...
    themeConfig: {
        sidebar: [
            ...sidebar.generateSidebarGroups(),
            
            // Optionally, you can generate sidebar items with another link prefix.
            ...sidebar.generateSidebarGroups({ linkPrefix: '/v2/' }),
        ],
    },
}Items by tags 
To generate sidebar items by tags, you can use the itemsByTags function. Configure your .vitepress/config.js as follows:
ts
import { useSidebar, useOpenapi } from 'vitepress-openapi'
import spec from '../public/openapi.json' assert { type: 'json' }
const sidebar = useSidebar({ 
    spec,
    // Optionally, you can specify a link prefix for all generated sidebar items.
    tagLinkPrefix: '/tags/',
})
module.exports = {
    // ...
    themeConfig: {
        sidebar: [
            ...sidebar.itemsByTags(),
            
            // Optionally, you can generate sidebar items with another link prefix.
            ...sidebar.itemsByTags({ linkPrefix: '/v2/' }),
        ],
    },
}
