To access Command Line Arguments in Node.js script file, use process.argv array that contains command line arguments that were passed when starting Node.js process. Command line arguments are usually used when your program is so generalized and you need to send in some values for the program ...
Command line arguments are often used to modify the behavior of an application or specify needed parameters for operation. In this lesson, you will learn how to access the command line arguments passed to your node.js application as well as different strategies for evaluating and accessing them. ...

Command Line Interface,顾名思义是一种通过命令行来交互的工具或者说应用。SPA应用中常用的如vue-cli, angular-cli, node.js开发搭建express-generator,orm框架sequelize-cli,还有我们最常用的webpack,npm等。他们是web开发者的辅助工具,旨在减少低级重复劳动,专注业务提高开发效率,规范develop workflow。 举比较典型的...
egg-bin 基于抽象命令行工具common-bin,一个抽象封装了诸如 yargs、co 模块,并提供对于 async/generator 特性的支持,内置了 helper、subcommand 等实用功能,也算是五脏俱全了,凭借这些封装可以以及对于 cli 文件结构的约定,可以大大简化一个 node 工具的开发流程。
nodejs 07 - command line programs 下面这些是nodejs常见的命令行程序,使用npm进行安装后,在终端中使用它们。 forever:使用forever让node.js持久运行, nodejs一般是当成一条命令执行的,当用户断开session,nodejs也就停止了运行。如何让nodejs持续在后台运行呢?
