Two days of results---node,express,mongodb, and Mongoose's analysis of GitHub's own blog-building projects

GitHub Address: Https://github.com/linguowei/myblog

Clone the project Git down;

Analysis:

# git clone https://github.com/linguowei/myblog.git# cd myblog# npm install# npm run build# CD admin # NPM Run build#. CD.. /# node app.js# localhost:7000# localhost:7000/admin

Run the code;

Which is connected to the data:

App.use (Router)

Database connection + set up various tables; db.js

Set up separately: Account form;

Article table;

Label table;

Personal Information Form;

Create articles, tags, and blog descriptions in Localhost:7000/admin;

The actual background operation:

Start Data debugging

View Articles's Articles

View Tags

Vue to Node,moogooes, MongoDB's request process

Here, I'll take the save tag.

The front-end sends the requested code:

Web page specific occurrence of requests;

Node+mongoose the processing and operation of the data;

Data processing in the background;

//article label save RouteRouter.post ('/api/savearticlelabel ',function(req, res) {db. Taglist.find ({},function(Err, docs) {if(ERR)return; varIsexist =false; //the data is traversed;Docs.foreach (function(item) {if(Item.tagname = =req.body.tagList.tagName) {Isexist=true; }        })       //exists without processing and returns an error        if(isexist) {Res.json ({error:true, msg: ' Tag already exists '})        }Else{            //Save to database            NewDb. TagList (req.body.tagList). Save (function(Error) {if(Error) {Res.send (' Save Failed '); return} res.send ()})

            Res.json ({success:true, msg: ' Save succeeded '})

} }) });

The specific use of the process is this, the actual use of more APIs, please view mongoose/express's documentation for use;
