Nodejs learning bit by bit

 

1. File generation

 

Mainly use fs, to operate,

 

this.generateFile = function(opt){
		
		var fs= require("fs");
		
		var target = opt.target;
		
		if(!html){
			generateHTML(root);
		}
		
		fs.writeFile(target,html,{flag:'w',encoding:'utf-8',mode:'0666'},function(err){
			if(err){
				console.log("can't generate html file!!");
			}else{
				console.log("build finish!!");
			}
		});
		
	}

 

Read file:

 

var fs= require("fs");

fs.readFile('package.json',function(err,data){
    if(err){
        console.log("can't find package.json!!")
    }else{
    	writeToFile(JSON.parse(data));
    }
});
