Peer Dependencies

Required:

npm install vue@^3.3.0 vue-router@^4.0.0

Optional (only if using Tailwind CSS):

npm install tailwindcss@^3.4.0 tailwindcss-animate@^1.0.7

Setup Options

Blario Vue works with or without Tailwind CSS. Choose the setup that fits your project:

Option 1: Without Tailwind CSS (Recommended for Vuetify, Element Plus, etc.)

Perfect for projects using Vuetify, Element Plus, Quasar, or any other UI framework.

1. Import Blario Styles:

// src/main.ts
import { createApp } from 'vue';
import App from './App.vue';

// Import your UI framework styles first
import 'vuetify/styles';

// IMPORTANT: Import Blario styles AFTER your UI framework
// This ensures Blario styles take precedence over framework CSS resets
import '@blario/vue/styles.css';

const app = createApp(App);
app.mount('#app');

⚠️ Import Order Matters: Always import @blario/vue/styles.css after your UI framework styles (Vuetify, Element Plus, etc.). UI frameworks often include CSS resets that can override spacing and margins. By importing Blario last, its utility classes will take precedence.

That's it! The bundled CSS includes all necessary styles without requiring Tailwind CSS.

2. Customize via CSS Variables (Optional):

/* src/style.css */
:root {
  --blario-primary: 220 95% 50%;        /* Your primary color in HSL */
  --blario-primary-foreground: 0 0% 100%;
  --blario-background: 0 0% 100%;
  --blario-foreground: 222 84% 5%;
  --blario-radius: 0.5rem;              /* Border radius */
}

.dark {
  --blario-background: 222 84% 5%;
  --blario-foreground: 210 40% 98%;
}

Option 2: With Tailwind CSS (Full Customization)

Perfect if you're already using Tailwind CSS and want deep integration.

1. Configure Tailwind CSS:

Add the Blario preset to your tailwind.config.js:

// tailwind.config.js
import blarioPreset from '@blario/vue/tailwind-preset';

export default {
  presets: [blarioPreset],
  content: [
    './index.html',
    './src/**/*.{vue,js,ts,jsx,tsx}',
    // IMPORTANT: Include Blario components in Tailwind scan
    './node_modules/@blario/vue/dist/**/*.{js,mjs,vue}',
  ],
  plugins: [],
};

2. Import Blario Styles:

// src/main.ts
import { createApp } from 'vue';
import App from './App.vue';
import '@blario/vue/styles.css'; // Import Blario styles

const app = createApp(App);
app.mount('#app');

Or import in your main CSS file:

/* src/style.css */
@import '@blario/vue/theme.css';
@import '@blario/vue/styles.css';

3. Import Tailwind directives in your CSS:

/* src/style.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

@import '@blario/vue/theme.css';

Quick Start (3 minutes)

After completing one of the setup options above, follow these steps:

1. Wrap Your App with BlarioProvider

<!-- src/App.vue -->
<template>
  <BlarioProvider
    :publishable-key="publishableKey"
    locale="en"
    :user="user"
    :capture="captureConfig"
    @after-submit="handleAfterSubmit"
    @error="handleError"
  >
    <router-view />
  </BlarioProvider>
</template>

<script setup lang="ts">
import { BlarioProvider } from '@blario/vue';

const publishableKey = import.meta.env.VITE_BLARIO_PUBLISHABLE_KEY;

const user = {
  id: 'user-123',
  email: '[email protected]',
  name: 'John Doe'
};

const captureConfig = {
  console: true,
  networkSample: false,
  maxConsoleLogs: 50,
  maxNetworkLogs: 20,
};

const handleAfterSubmit = (issueId: string) => {
  console.log('Issue submitted:', issueId);
};

const handleError = (error: Error) => {
  console.error('Blario error:', error);
};
</script>

2. Add the Reporter Button

<template>
  <div class="app">
    <!-- Optional: Show diagnostic banner -->
    <DiagnosticBanner />

    <!-- Your app content -->
    <main>
      <h1>Welcome to your app</h1>
    </main>

    <!-- Floating button (default) -->
    <IssueReporterButton />
  </div>
</template>

<script setup lang="ts">
import { IssueReporterButton, DiagnosticBanner } from '@blario/vue';
</script>

That's it! The issue reporter is now available in your Vue app.

  uploadProgress: Ref<UploadProgress[]>;
  clearUploadError: () => void;
}

Example:

<template>
  <div>
    <input
      type="file"
      multiple
      accept="image/*,video/*"
      @change="handleFileSelect"
    />

    <button
      @click="submitWithFiles"
      :disabled="isUploading"
    >
      {{ isUploading ? 'Uploading...' : 'Submit' }}
    </button>

    <div v-if="uploadError" class="text-red-600">
      {{ uploadError }}
    </div>

    <div v-if="isUploading">
      <div v-for="progress in uploadProgress" :key="progress.fileId">

      console.log('Issue submitted with files:', result.issueId);
      selectedFiles.value = [];
    }
  } catch (error) {
    console.error('Upload failed:', error);
  }
};
</script>

Programmatic Usage

Report issues without UI components using the useBlario composable:

<script setup lang="ts">
import { useBlario } from '@blario/vue';
import { onErrorCaptured } from 'vue';

const { reportIssue } = useBlario();

// Capture Vue errors
onErrorCaptured((error, instance, info) => {
  reportIssue({
    summary: `Vue Error: ${error.message}`,
    steps: `Component: ${instance?.$options.name}\nInfo: ${info}`,
    severity: 'high',
    category: 'vue-error',
    actual: error.stack,
  });

  return false; // Don't propagate error
});

// Custom error handler
const handleApiError = async (error: Error) => {
  await reportIssue({
    summary: `API Error: ${error.message}`,
    category: 'api',
    severity: 'medium',
  });
};
</script>

Vue Router Integration

Blario automatically integrates with Vue Router when available:

// src/main.ts
import { createApp } from 'vue';
import { createRouter } from 'vue-router';
import App from './App.vue';

const router = createRouter({
  // ... router config
});

const app = createApp(App);
app.use(router); // Blario will automatically track routes
app.mount('#app');

Route changes are automatically captured in issue context.

Styling & Customization

Blario provides multiple ways to customize the appearance based on your setup:

Without Tailwind CSS

When using the standalone CSS bundle, customize via CSS variables:

/* Customize theme colors */
:root {
  /* Primary brand color (HSL format: hue saturation% lightness%) */
  --blario-primary: 220 95% 50%;
  --blario-primary-foreground: 0 0% 100%;

  /* Background colors */
  --blario-background: 0 0% 100%;
  --blario-foreground: 222 84% 5%;
  --blario-card: 0 0% 100%;

  /* UI elements */
  --blario-border: 214 32% 91%;
  --blario-input: 214 32% 91%;
  --blario-radius: 0.5rem;

  /* Semantic colors */
  --blario-destructive: 0 84% 60%;
  --blario-muted: 210 40% 96%;
}

.dark {
  --blario-background: 222 84% 5%;
  --blario-foreground: 210 40% 98%;
  --blario-card: 222 84% 5%;
  --blario-border: 217 33% 18%;
}

With Tailwind CSS

When using Tailwind, the preset includes all necessary styles and theme variables:

// tailwind.config.js
import blarioPreset from '@blario/vue/tailwind-preset';

export default {
  presets: [blarioPreset],
  content: [
    './src/**/*.{vue,js,ts}',
    './node_modules/@blario/vue/dist/**/*.{js,mjs,vue}',
  ],
};

Then customize via Tailwind's theme extension:

// tailwind.config.js
import blarioPreset from '@blario/vue/tailwind-preset';

export default {
  presets: [blarioPreset],
  theme: {
    extend: {
      colors: {
        // Override Blario colors
        primary: {
          DEFAULT: 'hsl(220, 95%, 50%)',
          foreground: 'hsl(0, 0%, 100%)',
        },
      },
    },
  },
  content: [
    './src/**/*.{vue,js,ts}',
    './node_modules/@blario/vue/dist/**/*.{js,mjs,vue}',
  ],
};

Custom Button Styles

<template>
  <!-- Custom inline button -->
  <IssueReporterButton
    variant="inline"
    class="bg-purple-500 hover:bg-purple-600 text-white font-semibold px-6 py-3 rounded-lg shadow-lg transition-all hover:scale-105"
  >
    Report Issue
  </IssueReporterButton>

  <!-- Link style -->
  <IssueReporterButton
    variant="inline"
    class="text-blue-600 hover:text-blue-800 underline font-medium"
  >
    Contact Support
  </IssueReporterButton>

  <!-- Minimal style -->
  <IssueReporterButton
    variant="inline"
    class="text-gray-600 hover:text-gray-900 dark:text-gray-400 dark:hover:text-gray-100"
  >
    Report a Problem
  </IssueReporterButton>
</template>

Theme Configuration

<template>
  <BlarioProvider
    :theme="{
      mode: isDark ? 'dark' : 'light',
      position: 'bottom-left',
      accent: '#10b981',
      className: 'my-custom-reporter',
    }"
  >
    <App />
  </BlarioProvider>
</template>

<script setup lang="ts">
import { ref } from 'vue';
import { BlarioProvider } from '@blario/vue';

const isDark = ref(false);
</script>

Unstyled Components

For complete control, use the unstyled prop and bring your own styles:

<template>
  <IssueReporterButton
    unstyled
    class="my-custom-button"
  >
    <MyCustomIcon />
    Report Issue
  </IssueReporterButton>
</template>

<style scoped>
.my-custom-button {
  /* Your custom styles */
  background: linear-gradient(to right, #667eea, #764ba2);
  color: white;
  padding: 12px 24px;
  border-radius: 8px;
  /* ... */
}
</style>

Advanced Configuration

Custom PII Redaction

<template>
  <BlarioProvider
    :redaction="{
      patterns: [
        /api[_-]?key/gi,
        /password/gi,
        /secret/gi,
        /\b\d{16}\b/g, // Credit card numbers
      ],
      customRedactor: (text) => {
        return text.replace(/user_\d+/g, '[USER_ID]');
      },
    }"
  >
    <App />
  </BlarioProvider>
</template>

Rate Limiting

<template>
  <BlarioProvider
    :rate-limit="{
      maxRequests: 5,
      windowMs: 300000, // 5 minutes
    }"
  >
    <App />
  </BlarioProvider>
</template>

Custom API Endpoint

<template>
  <BlarioProvider
    api-base-url="https://your-api.example.com"
    :publishable-key="apiKey"
  >
    <App />
  </BlarioProvider>
</template>

  BlarioConfig,
  DiagnosticResponse,
  FormData,
  User,
  BlarioProviderProps,
  UseBlarioReturn,
  UseBlarioUploadReturn,
} from '@blario/vue';

// Type-safe usage
const config: BlarioConfig = {
  publishableKey: 'pk_xxx',
  user: {
    id: 'user-123',
    email: '[email protected]',
  },
};

Troubleshooting

Styles not applying

Without Tailwind CSS:

• Make sure you've imported @blario/vue/styles.css in your main file
• IMPORTANT: Import Blario styles after your UI framework styles (Vuetify, Element Plus, etc.)

  // ✅ Correct order
  import 'vuetify/styles';
  import '@blario/vue/styles.css';
  
  // ❌ Wrong order
  import '@blario/vue/styles.css';
  import 'vuetify/styles'; // This will override Blario styles

• Check that the CSS file is being loaded (inspect network tab in dev tools)
• If spacing/margins are not working, verify that Blario styles are loaded after framework styles
• Some UI frameworks (like Vuetify) use aggressive CSS resets (* { margin: 0; padding: 0; }). Blario includes !important on critical utilities to override these resets

With Tailwind CSS:

• Make sure you've added the Tailwind preset to tailwind.config.js
• Included Blario dist files in Tailwind content array
• Imported @blario/vue/styles.css in your main file
• Added Tailwind directives (@tailwind base/components/utilities) to your CSS

TypeScript errors with import.meta.env

Add Vite types to your tsconfig.json:

{
  "compilerOptions": {
    "types": ["vite/client"]
  }
}

Create src/vite-env.d.ts:

/// <reference types="vite/client" />

interface ImportMetaEnv {
  readonly VITE_BLARIO_PUBLISHABLE_KEY: string
}

interface ImportMeta {
  readonly env: ImportMetaEnv
}

Provider not found error

Make sure BlarioProvider wraps your entire app and is at the root level of your component tree.

Modal not opening

Verify that:

1. BlarioProvider is properly set up
2. You've imported the styles
3. The button has access to the Blario context (is inside BlarioProvider)

Migration from Plugin to Provider

If you were using the BlarioPlugin approach, migrate to BlarioProvider:

Before:

// main.ts
import { BlarioPlugin } from '@blario/vue';
app.use(BlarioPlugin, { publishableKey: 'pk_xxx' });

After:

<!-- App.vue -->
<template>
  <BlarioProvider publishable-key="pk_xxx">
    <router-view />
  </BlarioProvider>
</template>
