metadata	{"author":"jiaiyan","version":"1.0.0"}

Naive UI Discrete API Component

If you want to use useDialog, useMessage, useNotification, useLoadingBar, useModal outside setup, you can use createDiscreteApi to create corresponding API.

When to Use

Use this component when:

• Outside setup: Use Naive UI APIs outside Vue component setup
• Utility functions: Call message, dialog, etc. from utility files
• Global access: Access APIs from anywhere in the application
• Third-party integration: Integrate with non-Vue code

When to Invoke

Invoke this skill when:

• User needs to use message, dialog, notification outside a component
• User wants to create global API access
• User needs to call APIs from utility functions
• User asks about using Naive UI APIs outside setup

Features

• Outside Setup: Use APIs outside Vue component setup context
• Multiple APIs: Create message, dialog, notification, loadingBar, modal
• Config Provider: Support for config provider props
• Theme Support: Can configure theme and other providers
• App Access: Access to the underlying Vue app instance

API Reference

createDiscreteApi

function createDiscreteApi(
  includes: Array<'message' | 'dialog' | 'notification' | 'loadingBar'>,
  options: {
    configProviderProps: Ref<ConfigProviderProps> | ConfigProviderProps;
    messageProviderProps: Ref<MessageProviderProps> | MessageProviderProps;
    dialogProviderProps: Ref<DialogProviderProps> | DialogProviderProps;
    notificationProviderProps:
      | Ref<NotificationProviderProps>
      | NotificationProviderProps;
    modalProviderProps: Ref<ModalProviderProps> | ModalProviderProps;
    loadingBarProviderProps:
      | Ref<LoadingBarProviderProps>
      | LoadingBarProviderProps;
  },
): {
  message: MessageApi;
  dialog: DialogApi;
  notification: NotificationApi;
  loadingBar: LoadingBarApi;
  modal: ModalApi;
  app: App;
  unmount: () => void;
};

Basic Usage

Basic Discrete API

<template>
  <n-space>
    <n-button @click="handleMessageTriggerClick"> message </n-button>
    <n-button @click="handleNotificationTriggerClick"> notification </n-button>
    <n-button @click="handleDialogTriggerClick"> dialog </n-button>
    <n-button @click="handleLoadingBarTriggerClick"> loadingBar </n-button>
    <n-button @click="handleModalTriggerClick"> modal </n-button>
  </n-space>
</template>

<script setup>
import { createDiscreteApi, darkTheme } from 'naive-ui';

const { message, notification, dialog, loadingBar, modal } = createDiscreteApi([
  'message',
  'dialog',
  'notification',
  'loadingBar',
  'modal',
]);

const handleMessageTriggerClick = () => {
  message.info('This is a message');
};

const handleNotificationTriggerClick = () => {
  notification.create({
    title: 'Notification',
    content: 'This is a notification',
  });
};

const handleDialogTriggerClick = () => {
  dialog.warning({
    title: 'Warning',
    content: 'Are you sure?',
    positiveText: 'Confirm',
    negativeText: 'Cancel',
  });
};

const handleLoadingBarTriggerClick = () => {
  loadingBar.start();
  setTimeout(() => {
    loadingBar.finish();
  }, 2000);
};

const handleModalTriggerClick = () => {
  modal.create({
    title: 'Modal',
    content: 'This is a modal',
  });
};
</script>

Common Patterns

With Theme Configuration

<template>
  <n-space>
    <n-button @click="handleThemeChangeClick"> theme: {{ theme }} </n-button>
    <n-button @click="handleMessageTriggerClick"> message </n-button>
  </n-space>
</template>

<script setup>
import { ref } from 'vue';
import { createDiscreteApi, darkTheme } from 'naive-ui';

const theme = ref(null);

const { message } = createDiscreteApi(['message'], {
  configProviderProps: {
    theme: darkTheme,
  },
});

const handleThemeChangeClick = () => {
  theme.value = theme.value ? null : darkTheme;
};

const handleMessageTriggerClick = () => {
  message.info('Message with dark theme');
};
</script>

Utility File Usage

import { createDiscreteApi } from 'naive-ui';

const { message, dialog, notification } = createDiscreteApi([
  'message',
  'dialog',
  'notification',
]);

export function showSuccess(msg: string) {
  message.success(msg);
}

export function showError(msg: string) {
  message.error(msg);
}

export function confirmDelete(onConfirm: () => void) {
  dialog.warning({
    title: 'Delete Confirmation',
    content: 'Are you sure you want to delete this item?',
    positiveText: 'Delete',
    negativeText: 'Cancel',
    onPositiveClick: onConfirm,
  });
}

export function notifySuccess(title: string, content: string) {
  notification.success({
    title,
    content,
    duration: 3000,
  });
}

With Loading Bar

import { createDiscreteApi } from 'naive-ui';

const { loadingBar, message } = createDiscreteApi(['loadingBar', 'message']);

export async function withLoadingBar<T>(
  promise: Promise<T>,
  successMessage?: string,
): Promise<T> {
  loadingBar.start();
  try {
    const result = await promise;
    loadingBar.finish();
    if (successMessage) {
      message.success(successMessage);
    }
    return result;
  } catch (error) {
    loadingBar.error();
    message.error(error.message || 'An error occurred');
    throw error;
  }
}

Selective API Creation

import { createDiscreteApi } from 'naive-ui';

const { message } = createDiscreteApi(['message']);

message.info('Only message API is created');

Best Practices

1. Don't call in setup: Do not call createDiscreteApi in setup since it may cause unexpected behaviors

2. Not affected by providers: Discrete API won't be affected by n-xxx-provider in current app

3. Manual config sync: If you need to share config, you should sync them manually

4. Avoid mixing: Better not use discrete API and normal API together

5. Create once: Create the discrete API once and export for reuse

6. Unmount when done: Use the returned unmount function to clean up when no longer needed
