@conduction/nextcloud-vue

Shared Vue 2 component library for Conduction Nextcloud apps — higher-level UI, OpenRegister integration, and NL Design System support

---

@conduction/nextcloud-vue is an npm component library that sits on top of @nextcloud/vue and provides higher-level, opinionated components for building Nextcloud apps. It handles the repetitive patterns — schema-driven tables, CRUD dialogs, paginated lists, faceted search — so each app only writes the domain-specific parts.

Used internally by Pipelinq, Procest, Larping, and other Conduction Nextcloud apps.

Requires: Vue 2.7, Pinia 2, @nextcloud/vue 8

Loading

Two-Phase Dialog Pattern

All dialogs follow a predictable confirm/result flow that keeps parent components in control of API calls:

// 1. Dialog emits @confirm with user input
// 2. Parent handles API call
// 3. Parent calls dialog.setResult(response) via $ref
// 4. Dialog shows toast and auto-closes

Schema-Driven Components

Pass a JSON Schema and get a fully working table or form with zero configuration:

<CnIndexPage
  :schema="caseTypeSchema"
  :objects="caseTypes"
  @save="onSave"
  @delete="onDelete"
/>

Installation

npm install @conduction/nextcloud-vue

Import the CSS alongside your component imports:

import '@conduction/nextcloud-vue/dist/nextcloud-vue.css'
import { CnIndexPage, useObjectStore } from '@conduction/nextcloud-vue'

Webpack Alias (for local development)

When developing against the source directly, add deduplication aliases in webpack.config.js to prevent dual-instance bugs:

config.resolve.alias = {
  '@conduction/nextcloud-vue': path.resolve(__dirname, '../nextcloud-vue/src'),
  'vue': path.resolve(__dirname, 'node_modules/vue'),
  'pinia': path.resolve(__dirname, 'node_modules/pinia'),
  '@nextcloud/vue': path.resolve(__dirname, 'node_modules/@nextcloud/vue'),
}

Important: Without these aliases, webpack may resolve Vue and Pinia from the library's node_modules, creating dual instances that break reactivity and state management.
