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:
1 2 3 4 5 6 7 8 9 10 | 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
1 2 3 4 5 6 7 8 | [nodemon] 1.18.6 [nodemon] to restart at any time, enter `rs` [nodemon] watching: *.* [nodemon] starting `node app.js` Start app. false true [ 'Jonson', 1, 2, 3, 4 ] |
修改文件:
1 2 3 | var filteredArray = _.uniq(['Jonson',1,'Jonson',1,2,3,4]); 替换为: var filteredArray = _.uniq(['Jonson',1,'Jonson',1]); |
自动输出字符串:
1 2 3 4 5 6 7 | [nodemon] clean exit - waiting for changes before restart [nodemon] restarting due to changes... [nodemon] starting `node app.js` Start app. false true [ 'Jonson', 1 ] |
