FoxitPDFSDK for Web Example - Vue3

These guides have the following sections:

• Part 1: How to run this example
• Part 2: How to use FoxitPDFSDK for Web in Vue3
• Part 3: Q & A

Prerequisites

• Node.js and npm
• @foxitsoftware/foxit-pdf-sdk-for-web-library >= 9.0.0

Part 1: How to run this example

1. Clone the repository

git clone git@github.com:foxitsoftware/FoxitPDFSDKForWeb-Vue3-Example.git vue3-websdk

2. Enter the directory and run npm install

cd vue3-websdk
npm install

3. Update the licenseSN and licenseKey values in vue3-websdk/src/App.vue with your own licenseSN and licenseKey that you received from sales

4. Run project

npm run dev

5. Start snapshot serve

Navigate to vue3-websdk/public/FoxitPDFSDKForWeb/server/snapshot, and execute:

npm install
npm run start

6. Reference the Service-Worker-Allowed HTTP header

Starting from FoxitPDFSDK for Web version 10.0.0, since service worker is used, it is necessary to add this field in the HTTP response header of the Service Worker script. Its value is the maximum allowed scope path:

Service-Worker-Allowed /;

Nginx 配置示例

If you are using Nginx as your server, you can add the Service-Worker-Allowed response header by modifying the Nginx configuration file. Below is an example configuration：

server {
    location /sw.js {
        add_header Service-Worker-Allowed /;
    }
}

Webpack Dev Server 配置示例

If you use Webpack Dev Server for local development, you can add Service-Worker-Allowed response headers by configuring devServer. The following is a configuration example：

// webpack.config.js
module.exports = {
    // 其他配置
    devServer: {
        headers: {
            'Service-Worker-Allowed': '/'
        }
    }
};

Part 2: How to use FoxitPDFSDK for Web in Vue3

1. Create project

Execute the command npm init vue@latest and follow the wizard to complete the setup:

• Project name: -> vue3-websdk
• Add TypeScript? -> No
• Add JSX Support? -> No
• Add Vue Router for Single Page Application development? -> No
• Add Pinia for state management? -> No
• Add Vitest for Unit testing? -> No
• Add Cypress for both Unit and End-to-End testing? -> No
• Add ESLint for code quality? -> No
• Add Prettier for code formatting? -> No

2. Install dependence

cd vue3-websdk
npm install
npm install @foxitsoftware/foxit-pdf-sdk-for-web-library
npm install -D rollup-plugin-copy

3. Update vue3-websdk/src/App.vue to follow

<script setup>
import '@foxitsoftware/foxit-pdf-sdk-for-web-library/lib/UIExtension.css';
import * as UIExtension from '@foxitsoftware/foxit-pdf-sdk-for-web-library/lib/UIExtension.full.js';
import preloadJrWorker from '@foxitsoftware/foxit-pdf-sdk-for-web-library/lib/preload-jr-worker.js';
import {onMounted} from 'vue';

onMounted(() => {
  const licenseSN = 'xxx';
  const licenseKey = 'xxx';

  const readyWorker = preloadJrWorker({
    workerPath: '/FoxitPDFSDKForWeb/lib/',
    enginePath: '../lib/jr-engine/gsdk',
    fontPath: 'http://webpdf.foxitsoftware.com/webfonts/',
    licenseSN: licenseSN,
    licenseKey: licenseKey
  });

  const PDFUI = UIExtension.PDFUI;
  const pdfui = new PDFUI({
    viewerOptions: {
      libPath: '/FoxitPDFSDKForWeb/lib',
      jr: {
        readyWorker: readyWorker
      }
    },
    renderTo: '#pdf-ui',
    appearance: UIExtension.appearances.adaptive,
    fragments: [],
    addons: UIExtension.PDFViewCtrl.DeviceInfo.isMobile ?
        '/FoxitPDFSDKForWeb/lib/uix-addons/allInOne.mobile.js':
        '/FoxitPDFSDKForWeb/lib/uix-addons/allInOne.js'
  });
});
</script>

<template>
  <div class="fv__ui-nav">
    <div class="fv__ui-nav-logo">
      <i class="fv__icon-logo"></i>
    </div>
  </div>
  <div id="pdf-ui"></div>
</template>

<style scoped>
#pdf-ui {
  top: 40px;
  bottom: 0;
  position: absolute;
  width: 100vw;
}
</style>

4. Update the licenseSN and licenseKey values in vue3-websdk/src/App.vue with your own licenseSN and licenseKey that you received from sales

5. Update vue3-websdk/vite.config.js to follow

import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

import path from 'node:path';
import { normalizePath } from 'vite';
import copy from 'rollup-plugin-copy'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    copy({
      targets: [
        {
          src: normalizePath(path.resolve(__dirname, 'node_modules/@foxitsoftware/foxit-pdf-sdk-for-web-library/lib')),
          dest: normalizePath(path.resolve(__dirname, 'public/FoxitPDFSDKForWeb'))
        },
        {
          src: normalizePath(path.resolve(__dirname, 'node_modules/@foxitsoftware/foxit-pdf-sdk-for-web-library/server')),
          dest: normalizePath(path.resolve(__dirname, 'public/FoxitPDFSDKForWeb'))
        }
      ],
      hook: 'buildStart'
    })
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  },
  server: {
    proxy: {
      '/snapshot': 'http://localhost:3002',
    },
    headers: {
      'Service-Worker-Allowed': '/'
    }
  }
})

6. Update vue3-websdk/src/main.js to remove Vue3 default style:

- import './assets/main.css'
+ // import './assets/main.css'

import { createApp } from 'vue'
import App from './App.vue'

createApp(App).mount('#app')

7. Run project

npm run dev

8. Start snapshot serve

Navigate to vue3-websdk/public/FoxitPDFSDKForWeb/server/snapshot, and execute:

npm install
npm run start

Part 3: Q & A

1. After autoprefixer is used, a large number of logs are generated on the console. How can I solve this problem?

Remove the import '@foxitsoftware/foxit-pdf-sdk-for-web-library/lib/UIExtension.css'; from App.vue，Add <link rel="stylesheet" href="/FoxitPDFSDKForWeb/lib/UIExtension.css"> to index.html.
