Nodejs commander code#

This means weвЂ™ll want the name of the directory weвЂ™re working in, not the directory where the application resides. This will work when weвЂ™re calling the application from the same directory (for example, using node index.js), but bear in mind that weвЂ™re going to be making our console application available globally. This sounds straightforward, but there are a couple of gotchas to take into consideration.ДЇirstly, you might be tempted to use the fs moduleвЂ™s realpathSync method to get the current directory: path.

check whether a directory exists (to determine whether the current folder is already a Git repository by looking for a folder named.

get the current directory (to get a default repo name).

inquirer.js - command-line user interaction.

Nodejs commander code#

WeвЂ™re going to create a lib folder where weвЂ™ll split our helper code into modules: touch - a tool for implementing the Unix touch command.simple-git - a tool for running Git commands in a Node.js application.- an implementation of one of GitHubвЂ™s authentication strategies.- a GitHub REST API client for Node.js.configstore - easily loads and saves config without you having to think about where and how.ДЄdditionally, weвЂ™ll also be using the following:.inquirer - creates interactive command-line user interface.clui - draws command-line tables, gauges and spinners.HereвЂ™s a complete list of the packages weвЂ™ll use specifically for developing on the command line: WeвЂ™ll also be using minimist to parse command-line arguments. As well as providing a mechanism for asking questions, it also implements simple input controls: think radio buttons and checkboxes, but in the console. But weвЂ™re going to take advantage of a third-party package which adds a greater degree of sophistication - Inquirer. In terms of input and output, the low-level Readline Node.js module could be used to prompt the user and request input, and in simple cases is more than adequate. Just for fun, weвЂ™ll use figlet to create a fancy ASCII-based banner, and weвЂ™ll also use clear to clear the console. WeвЂ™ll be looking at a couple of libraries for enhancing the display: chalk for colorizing the output and clui to add some additional visual components. You might be surprised by just how much you can do visually, while at the same time keeping it functional. Nevertheless, that doesnвЂ™t mean it has to be plain, ugly, monochrome text. One thing is for certain: in terms of appearance, the console will never have the sophistication of a graphical user interface. It might not save you hours, but itвЂ™ll remove some of the initial friction when starting a new project. gitignore file, add the contents of the folder and push it up to the remote repository. Then it will provide a simple interactive вЂњwizardвЂќ for creating a. So what ginit will do is create a Git repository in the current folder, create a remote repository - weвЂ™ll be using GitHub for this - and then add it as a remote. WouldnвЂ™t it be better if we could do all this from the command line, with no copy-pasting of Git URLs and such like? Nevertheless, these steps are pretty repetitive. There are often more steps involved, but weвЂ™ll stick to those for the purposes of our app. create a remote repository, for example on GitHub or Bitbucket - typically by leaving the command line and firing up a web browser.initialize the local repository by running git init.For example, as part of a typical workflow, you may well: However, thatвЂ™s usually only one of a number of repetitive steps involved in the process of hooking up a new or existing project to Git. YouвЂ™re probably wondering what on earth that means.ДЄs you no doubt already know, git init initializes a Git repository in the current folder. For more in-depth JavaScript knowledge, read our book, JavaScript: Novice to Ninja, 2nd Edition.ДЇor this tutorial, weвЂ™re going to create a command-line utility which IвЂ™m calling ginit. gitignore file, and finally perform an initial commit and push.ДЄs ever, the code accompanying this tutorial can be found on our GitHub repo. It will also create a remote repository on GitHub right from the command line, allow the user to interactively create a. Sure, itвЂ™ll run git init under the hood, but itвЂ™ll do more than just that. What weвЂ™re going to build is a tool for initializing a Git repository. WeвЂ™re going to start by looking at a number of third-party packages designed to help work with the command line, then build a real-world example from scratch. Microservices, REST APIs, tooling, working with the Internet of Things and even desktop applications: itвЂ™s got your back.ДЄnother area where Node.js is really useful is for building command-line applications - and thatвЂ™s what weвЂ™re going to be doing in this article. As great as Node.js is for вЂњtraditionalвЂќ web applications, its potential uses are far broader.
