nodejs渐入佳境[5]-nodemon实现自动测试

nodemon

nodemon帮助我们,当我们修改文件时,node程序自动从新执行。

安装

1
> npm install -g nodemon

原始文件

app.js:

console.log('Start app.');

const _ = require('lodash');
判断是否为字符串
console.log(_.isString(true));
console.log(_.isString("abc"));

//筛选重复数组
var filteredArray = _.uniq(['Jonson',1,'Jonson',1,2,3,4]);
console.log(filteredArray);

打开控制台,在当前目录下输入:

1
> nodemon app.js

输出字符串
