浏览器书签的参考书目生成器：它是如何工作的

一个简单的参考书目生成器使用浏览器书签文件作为其源内容。数据库本身实际上是一个 JSON 对象文件，我们可以在本地保存和使用它。例如，这可以让我在 Chrome、Edge 和 Firefox 上获得相同的书签集，而无需浏览器保存我的书签数据。我们编辑书签文件夹以提取我们想要使用的唯一书签。

一个简单的参考书目生成器，使用JSON 浏览器书签文件作为其源内容。

先决条件和代码

参考书目生成器操作的第一个要求是其内容数据源，该源由名为xbrowserSync的浏览器书签管理器应用程序创建的 JSON 对象组成。该应用程序是一个与浏览器无关的书签管理器，分为两部分。

一部分是浏览器扩展，另一部分是服务器 API，它将书签数据作为MongoDB数据文件进行管理。关于服务器 API，我们需要了解的只是它的 URL。该浏览器扩展程序可以在在线应用程序“商店”中找到，例如 Chrome 浏览器的Google Play 。

基本思想是xbrowserSync应用程序将您的书签数据存储在存储在 API 服务器上的加密数据库中。数据库本身实际上是一个 JSON 对象文件，我们可以在本地保存和使用它，并且可以由任何适当安装了我们的应用程序扩展的浏览器使用。

例如，这可以让我在 Chrome、Edge 和 Firefox 上获得相同的书签集，而无需让浏览器保存我的书签数据。 xbrowserSync的 APP 和 API 源均位于GitHub 存储库中。

参考书目生成器的第二个要求是其程序代码在我的Windows 10计算机上的命令窗口中的node.js下运行。下面是这个名为handler.js的简单节点程序。

 #!/usr/bin/env node // --------------------------------- // Simple bibliography file handler Node Server API // --------------------------------- const fs = require('fs') const path = require('path') //const dn = require('./dirname'); var filePath = './bibliotest.json'; //the biblio bookmark file var biblio = ''; var str = ''; var searchValue = 'url:'; // -------------- // read and parse biblio JSON file // ---------------- const jsonReader = () => { return new Promise(resolve => { str = fs.readFile(filePath, (err, fd) => { object = JSON.parse(fd); str = object.children; // strip outer layer biblio = str; // count biblio array elements count = biblio.length; resolve (str); //return str; }) }) } // async function performAsyncFunctions(){ // list of promises to execute sequentially const firstRequest = await jsonReader(); //console.log('\nAll tasks complete.'); console.log('==== function complete ====\n') console.log('count = ', count) var html = '<html><lang = en><head></head><body>'; for (let i = 0; i < count; i++) { html = html + '<h3><i>id'+[i]+':</i>&nbsp;<a href='+biblio[i].url+'>'+biblio[i].title+'</a></h3><p>'+biblio[i].description+'</p>\n'; } html = html + '</body></html>'; console.info(html); const content = html try { const data = fs.writeFileSync('./bibliotest.html', content) //file written successfully } catch (err) { console.error(err) }} // --------------- performAsyncFunctions(); // console.log('biblio = ', object) // ------------------

JSON 格式书签文件

从xbrowserSync浏览器扩展菜单中，我们可以选择保存书签数据的备份。备份保存为 JSON 文件。对于我们这里的示例，所有书签都位于名为“MuskArticle”的书签文件夹中。

我们编辑书签 JSON 以仅提取我们想要在参考书目中使用的书签文件夹。该 JSON 文件如下所示。
