"Learning Notes" node. JS Learning Note (ii)

Iii. using node. js for Web Development

1. Install Express

　　　　Express is the officially recommended Web development framework and is very powerful.

Enter NPM Install-g Express on the command line for global installation Express

　　　　

This means that the installation is complete. But at this point we do not succeed in executing the express-h command, because express4.0 will need to install the Express-generator package to execute the Express command.

Re-install the Express-generator package: NPM install-g express-generator

So you can use Express command.

　　　　　　　

　　2. Establishment of the project

　　　　Express needs to specify the engine frame when initializing the project, the default bit jade, and the Ejs. Ejs is a label replacement engine, similar to PHP, so I decided to learn it based on it. And Jade is a complete set of syntax used to generate HTML for each tag structure, powerful and complex, so later to learn slowly.

　　　　After the new version, enter EXPRESS-E Ejs microblog

　　　　

This creates a new project, which is also a reminder of the need to install dependencies

We can enter CD microblog && NPM intall.

Enter the bin directory, input node Www.js can access the local server, in the browser input http://localhost:3000/can be seen.
