MongoDB + Express + node + bootstrap build multi-person Blog

This blog explains how to build a multiplayer blog, which requires a certain amount of basic knowledge for thought-finishing and memo-writing.

The first step: Create a new folder blog, the structure is as follows:

• The bin---executable binary, the final boot interface.
• Models---Store files related to data and operational data.
• Public---store static files.
• Routes---store routing files.
• Views---store view files.
• App.js---program Master file.
• Package.json---program related information.

Step Two: Install the dependent module

CNPM Install Express express-session Connect-mongo connect-flash ejs markdown multer Morgan Serve-favicon Debug Cookie-par Ser Body-parser MongoDB--save

The main functions of the module are as follows:

• Express---Web framework
• Express-session---Express session middleware for session processing
• Connect-mongo---Used in conjunction with session to connect the session to the database
• Connect-flash---Page hints middleware, based on session implementation
• Ejs---template engine
• Markdown---markdown text parsing middleware.
• Multer---The form data that is used to process enctype= "Multipart/form-data".
• Morgan---log middleware.
• Serve-favicon---Processing Web site icon Middleware
• Debug---debugging using
• Cookie-parser---middleware for processing cookies
• Body-parser---Middleware for processing post requests
• MongoDB---Connection database

Step three: Add a configuration file

Add the Setting.js file in the home directory, configure the port number, database and other basic information, as follows:

Module.exports = {    'myblog',     'blog'  ,    'localhost',    27017};

Fourth step: function design and routing design

• Register, login, log out
• View articles, edit articles, post articles, delete articles
• Comments (Messages)
• Page notification: implemented using Connect-flash. Connect-flash is based on the session, the principle is simple: Set the initial value, req.session.flash={} by req.flash(name, value) setting the field and value under this object, by req.flash(name) getting the value under this object, and delete this field.

Fifth Step: Permission settings

Add the Middlewares folder to the home directory and add the file Check.js as follows:

Module.exports ={checklogin:function Checklogin (req, res, next) {if(!req.session.user) {Req.flash ('Error','not logged in'); returnRes.redirect ('/signin');  } next (); }, Checknotlogin:function Checknotlogin (req, res, next) {if(Req.session.user) {Req.flash ('Error','is logged in'); returnRes.redirect (' Back');//return to previous page} next (); }};

Sixth step: Routing Files

Set up routing based on features
