We need to produce a 1500+ word article, 6-8 paragraphs each 150-250 words. Title already given, but we must output only the body (no title). Must be natural, conversational, avoid AI clichés. Must meet word count. Let's aim for 7 paragraphs of about 210 words each = 1470, need >1500, so maybe 8 paragraphs of ~200 words each = 1600. Ensure each paragraph 150-250 words, so 8 paragraphs of around 200 words each = 1600 words, meeting >1500. Each paragraph must be 150-250 words, so 200 is fine.
We need to cover "vue链接数据库" with practical steps, pitfalls, examples. Use natural language, avoid forbidden words. Avoid AI buzzwords like "", etc. Use short sentences, active voice, no passive.
We must not use headings, just paragraphs separated by line breaks. Ensure no "" etc. We can use "拿起" etc.
Let's craft 8 paragraphs, each ~200 words.
Paragraph1: intro tying to title, talk about why connecting Vue to DB matters, simple analogy.
Paragraph2: environment setup, installing backend, choosing DB, quick demo.
Paragraph3: API design, RESTful endpoints, using fetch or axios, handling CORS.
Paragraph4: authentication and security basics, token, JWT, avoid exposing secrets.
Paragraph5: handling data on front end, reactive refs, loading states, error handling.
Paragraph6: common pitfalls, CORS, schema mismatches, performance, debugging tips.
Paragraph7: real-world example with CRUD, show code snippets in brief natural language.
Paragraph8: wrap up, reflect on title, future improvements.
Word count per paragraph about 200. Let's write.
Need to count words. Let's approximate.
I'll craft each paragraph ~200 words.
Paragraph1: about 200 words.
Paragraph2: about 200 words.
Paragraph3: about 200 words.
Paragraph4: about 200 words.
Paragraph5: about 200 words.
Paragraph6: about 200 words.
Paragraph7: about 200 words.
Paragraph8: about 200 words.
Be careful not to use forbidden transition words. Avoid "", "". Use natural flow.
Paragraph1 (approx 200 words):
"Vue前端连接数据库全攻略，从零到实战一步到位——这句标题其实已经把核心问题点得很清楚。前端同学不再把数据库看作遥不可及的黑箱，而是直接在浏览器里拿到想要的数据。想象一下，你写好一个页面，点几下按钮，后端的数据就自动滚进来，像是现场演出的道具被即时补给。这背后最关键的环节就是把Vue和数据库打通。今天就带你从最基础的环境搭建，到最实用的API调用，再到常见的坑，一步步把理论变成可运行的代码。全程不讲空话，只要你跟着敲代码，就能在几分钟内看到自己的页面实时拉取数据。准备好一起动手了吗？"
Count words: Let's count roughly. Might be ~160. Need 150-250. It's okay but need to be in 150-250 range. Let's count: "Vue(1)前端2连接3数据库4全攻略，5从6零7到8实战9一步10到11位——这12句13标题14其实15已经16把17核心18问题19点得20很21清楚。前端22同学23不再24把25数据库26看作27遥不可及的28黑箱，29而是30直接31在32浏览器33里34拿到35想要的36数据。想象一下，37你写好38一个39页面，40点几下41按钮，42后端的43数据44就45自动46滚进来，47像是48现场演出的49道具50被51即时补给。这背后52最53关键的54环节55就是56把57Vue和58数据库59打通。今天60就61带你62从63最基础的64环境搭建，65到最实用的66API调用，67再到68常见的69坑，一步步70把71理论72变成73可运行的74代码。全程不讲空话，75只要76你77跟着78敲代码，79就能80在81几分钟82内看到83自己的84页面实时拉取数据。准备好85一起86动手了吗？"
That's about 86 words? Actually I think I miscounted; need to recount. But it's okay; we need 150-250 words per paragraph. Let's aim for ~200 words. I'll write longer paragraph.
I'll rewrite paragraph with more content to reach ~200 words.
Paragraph1: Let's write about 200 words.

Now count words: Let's count roughly: I think it's around 210-230 words. Good.
Paragraph2: about 200 words, covering environment setup.
"先把后端搭起来，这一步决定了后面所有调用的可靠性。这里推荐使用Node.js配合Express，因为这套组合轻量、社区资源多，而且不需要额外装数据库驱动。你需要在本地装好Node，然后在终端运行npm init生成package.json，接着安装Express和body-parser这两个依赖，代码可以写成npm install express body-parser。接下来，打开文件server.js，写一个最小的服务器示例，监听3000端口，返回一段文字确认运行。随后，我们要把数据库接入进来。这里选用MongoDB，因为它是文档型数据库，和JavaScript的对象非常相近，配合Mongoose可以直接用对象方式操作。安装mongoose后，创建一个db.js文
