How can newbies create a personal blog through Vue.js + Node.js

This article mainly introduces how novices can create a personal blog through Vue.js + Node.js. The article introduces it in great detail through sample code. It has certain reference and learning value for everyone. I hope it can help everyone. .

Plan

• UI style: mainly refer to the style of Randy's Blog, and add a little of my own ideas (mainly for laziness).

• Front-end page: Responsive SPA based on Vue2.0, ah? You ask me why? Just like the self-introduction in "About": I consider myself good at Vue SPA development.

• Backend: A shortcut for front-end engineers to the full stack: Node.js. Responsible for writing interfaces and rendering static pages.

• Database: The original plan was to use MongoDB, but in order to keep up with the schedule, the database was simply not used. This is the first version.

• Article: Refer to hexo’s method of writing an article using markdown syntax and then converting it to html. Articles in md format are also edited locally and uploaded to the server. Node.js directly reads the md file and converts it into html and returns it to the front desk. This is why a database is not needed for the time being.

• Deployment: AWS, free for one year! You ask me what I will do in one year? God knows! Maybe one year has allowed me to go from getting started to giving up.

Sail! set sail!

1. Page layout: See Cloud's Blog for yourself and give a brief introduction. The first screen is a wallpaper with 100% width and height covering the entire visible area. The content includes the blog name, subtitle and three links about the blogger; click the downward arrow to scroll to the main topic of the second screen, which is divided into four Tab modules: [Home], [Article], [Works], [About]. The default is [Homepage], which is the latest article details, [Article] is the article list, click to read the article content, [Works] is the work list, this part is not completed yet, [About] is some introduction about the blogger. PS: I spent a whole morning searching for the wallpaper on the first screen in Google Images before I found this one, which I am quite satisfied with. Considering that the wallpaper on the mobile phone is centered and covers the entire visible area, I have to find one that looks good on the PC and mobile phones. It’s really not easy to create pictures that are not too low-quality. BTW, bloggers still choose patients with difficulty.

2. Front-end development: start with Vue scaffolding

   
   

3. # 全局安装 vue-cli
   $ npm install --global vue-cli
   # 创建一个基于 webpack 模板的新项目
   $ vue init webpack blog
   # 安装依赖，走你
   $ cd blog
   $ npm install
   $ npm run dev

   Copy after login

4. Then install Vue -router is used for SPA routing and vue-resource or axios is used for Ajax.

   $ npm install --save vue-router
   $ npm install --save axios
   # vue官方推荐的ajax库不再是vue-resource,而是axios

   Copy after login

   Then you can start to code the static page. It should not be difficult to write the static page based on the page layout idea in the first step. You need to call the interface provided by node.js in the third step, which will not be discussed here. Say no more. After completing the static page, compile

   $ npm run build

   Copy after login

5. Back-end development: Create the server directory structure and install the express framework and marked for converting md files into html

   $ mkdir blog-server && cd blog-server
   $ mkdir public
   $ npm install --save express$ npm install --save marked

   Copy after login

   Writing interface , currently there are three main interfaces.

   Render the static page, copy the static files compiled in the second part and the article files in md format into the public folder, and use express's built-in middleware to specify the public folder as the root directory of the static resource file and cache it. . Because it is a single-page application, remember to handle 404 errors.

   # server.jsvar express = require('express');var app = express();
   app.use(express.static('public',{maxAge:60*60*24*30}));
   app.get('/',function(req,res){
    res.sendFile('/index.html',{root: __dirname + '/public/'});
   });
   app.listen(80);

   Copy after login

1. Get the article list interface. The fs.readdir method reads the folder where the md file is located, returns the file names of all md files, that is, the article title, creation time, and article path, and sorts them by creation time and renders them on the [Article] page.

2. Article content interface. According to the file name and path returned by the first interface, use the fs.readFile method to read the content of the md file and use marked to convert it to HTML and return it to the client, rendering it on the article content page.

3. Home page content interface. Similar to interface 2, read the latest article and return it. Remember to handle cross-domain issues.

   app.all('*', function(req, res, next) {
   res.header("Access-Control-Allow-Origin", "*");
   res.header("Access-Control-Allow-Headers", "X-Requested-With");
   res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS");
   res.header("X-Powered-By",' 3.2.1')
   res.header("Content-Type", "application/json;charset=utf-8");
   next();
   });

   Copy after login

6. Deployment

• Apply for AWS (Amazon cloud host), one-year free trial, credit card information is required. Instance an EC2, win or Linux system, Linux is recommended. Open the corresponding port and install node.js.

• Install PM2, run the server.js service in the third step, and let PM2 start with the system.

  $ npm install -g PM2
  $ pm2 start server.js
  $ pm2 startup

  Copy after login

  此时我们的博客系统已经运行在EC2上了。
