Quick Start

Installation

npm i tdesign-miniprogram -S --production

Modify app.json

Remove "style": "v2" from app.json to avoid style conflicts.

Modify project.config.json

Add the following to the setting section of project.config.json:

{
  "setting": {
    "packNpmManually": true,
    "packNpmRelationList": [
      {
        "packageJsonPath": "./package.json",
        "miniprogramNpmDistDir": "./"
      }
    ]
  }
}

Modify tsconfig.json (TypeScript projects)

{
  "paths": {
    "tdesign-miniprogram/*": [
      "./miniprogram/miniprogram_npm/tdesign-miniprogram/*"
    ]
  }
}

After modifying project.config.json, build npm in WeChat DevTools: Tools - Build npm

After successful build, check Compile JS to ES5

<t-button theme="light" size="large">Light Button</t-button>
<t-button size="large">Default Button</t-button>

<!-- Outline and Text Buttons -->

  >Outline Button</t-button
>
<t-button theme="primary" size="large" variant="text">Text Button</t-button>

<!-- Icon Button -->
<t-button
  theme="primary"
  icon="app"
  content="Icon Button"
  size="large"
></t-button>

<!-- Loading State -->
<t-button theme="primary" size="large" loading>Loading</t-button>

<!-- Disabled State -->
<t-button theme="primary" size="large" disabled>Disabled</t-button>

<!-- Block Button -->
<t-button theme="primary" size="large" block>Block Button</t-button>

<!-- Ghost Button (transparent background) -->
<t-button theme="primary" ghost size="large">Ghost Button</t-button>

Input

{
  "usingComponents": {
    "t-input": "tdesign-miniprogram/input/input"
  }
}

<t-input
  label="Label"
  placeholder="Please enter"
  value="{{value}}"
  bind:change="onChange"
/>

Dialog

{
  "usingComponents": {
    "t-dialog": "tdesign-miniprogram/dialog/dialog"
  }
}

<t-dialog
  visible="{{visible}}"
  title="Dialog Title"
  content="Dialog content"
  confirm-btn="Confirm"
  cancel-btn="Cancel"
  bind:confirm="onConfirm"
  bind:cancel="onCancel"
/>

Toast

import Toast from 'tdesign-miniprogram/toast/index';

Toast({
  context: this,
  selector: '#t-toast',
  message: 'Toast message',
});

AI Chat Interface

{
  "usingComponents": {
    "t-chat-list": "tdesign-miniprogram/chat-list/chat-list",
    "t-chat-message": "tdesign-miniprogram/chat-message/chat-message",
    "t-chat-sender": "tdesign-miniprogram/chat-sender/chat-sender"
  }
}

<t-chat-list layout="single">
  <t-chat-message
    avatar="{{item.avatar}}"
    name="{{item.name}}"
    content="{{item.content}}"
    role="{{item.role}}"
  />
  <view slot="footer">
    <t-chat-sender bind:send="onSend" />
  </view>
</t-chat-list>

Component({
  data: {
    messages: [
      {
        role: 'user',
        content: [{ type: 'text', data: 'Hello' }],
      },
      {
        role: 'assistant',
        content: [{ type: 'text', data: 'Hello! How can I help you?' }],
      },
    ],
  },
  methods: {
    onSend(e) {
      const { value } = e.detail;
      // Handle send message
    },
  },
});

Style Customization

Method 1: Using Style Attribute

<t-button style="color: red">Custom Style</t-button>
<t-button custom-style="color: red">Custom Style</t-button>

Method 2: Disable Style Isolation

Override styles directly in page:

.t-button--primary {
  background-color: navy;
}

In custom components, enable styleIsolation:

Component({
  options: {
    styleIsolation: 'shared',
  },
});

Method 3: External Style Classes

<t-button t-class="my-button-class">Button</t-button>

.my-button-class {
  background-color: navy !important;
}

Method 4: CSS Variables

TDesign provides rich CSS variables for theme customization:

page {
  --td-button-primary-bg-color: #0052d9;
  --td-button-border-radius: 8rpx;
}

Dark Mode

1. Modify app.json

{
  "darkmode": true
}

2. Import Design Token

In app.wxss:

@import 'miniprogram_npm/tdesign-miniprogram/common/style/theme/_index.wxss';

3. Use CSS Variables

.text {
  color: var(--td-text-color-secondary);
}

4. Special Component Adaptation

For components wrapped in custom-tab-bar or root-portal, add .page class:

<view class="page">
  <t-tab-bar />
</view>
