node. JS Self-study Road--1. Environment construction

Order--

The "node. JS self-paced" series of articles will document my learning process for Web development based on node. js.

node. JS is a development platform based on the V8 engine that performs JavaScript faster and with good performance, and because it is a language for development in JavaScript, it has a lower learning curve and more efficient development for front-end engineers.

I. Installing node. js

1. Go to the node. JS website to download and install

2. Start the cmd Input command to view the node and NPM versions

Node-vnpm-v

NPM is the package Manager that node comes with when it finishes installation

Ii. installation of Express

Express is the most common Web application development framework under node platform

1. Global Installation Express

NPM Install-g Express

WIN7 environment is installed globally under the C:\Users\Administrator\AppData\Roaming\npm\node_modules folder

2. Global Install Express command line tool

NPM install-g Express-generator

In the latest version of 4.x, command-line tools have been isolated

3. View Express version

Express-v

4. Update the Installed Express

NPM Update-g Express

Iii. creating a project using Express

1. Create a project

Express App_name

Express defaults to Jade as the template engine

2. Create a project with Ejs as a template engine

Express-e app_name

3. Installing dependent Packages

Go to the project folder and execute:

NPM Install

Download all dependent packages recorded in Package.json to the Node_modules folder

Iv. Start-up service

1. Start

NPM start

Listen to the Bin/www file, the default port is 3000, can be changed in the www file

2. Open the browser and enter localhost:3000

3. Automatic Restart Service

Open Package.json can see that the command to listen to the Bin/www file is node

Using node monitoring will result in the need to manually restart the service after each code modification, which can be automatically restarted using Nodemon

NPM install-g Nodemon

You can also use the following command to view its version

Nodemon-v

Modify the code in the Package.json file to:

"Start": "Nodemon./bin/www"

Re-execute:

NPM start

Next, you will be able to code the arbitrary ...

node. JS is growing fast, packages are upgraded quickly, and articles are not available in the official documentation. I also do not update the article regularly, try to maintain the usability of the article code.
