Once Jekyll is installed, you can serve the sample website by using Bundler to execute the correct version of the jekyll program: $ bundle exec jekyll serveĪt this point, the app will be running on localhost:4000, and should look something like Figure 11.5.įigure 11.5: Our initial sample app. Then use the bundle command to install the jekyll gem listed in the Gemfile included with the repository: $ bundle _2.2.17_ install The short version is that you first need to install Bundler: $ gem install bundler -v 2.2.17 The Jekyll setup instructions ( ) in Learn Enough CSS & Layout to Be Dangerous explain how to install Jekyll on your system in case it isn’t installed already. In either case, once the app is put together you can run it using the Jekyll static site builder. github.io that isn’t the result of following Learn Enough CSS & Layout to Be Dangerous, I’ll assume you have the requisite technical sophistication to figure something out on your own.) $ cp -r images/* /path/to/repo/.github.io/images/ $ cp gallery/index.html /path/to/repo/.github.io/gallery/ # from following Learn Enough CSS & Layout to Be Dangerous. In particular, you’ll need the gallery index.html and the large and small images: # Run these commands only if you already have. This will create a local repository called le_js_full, which you can use as a reference for copying over the required files. github.io from following Learn Enough CSS & Layout to Be Dangerous, you should clone the gallery app (without renaming it) to the default directory by omitting the second argument to git clone: $ git clone # Command if you already have. Because our starting point is the professional-grade website developed in Learn Enough CSS & Layout to Be Dangerous, the result is unusually polished for a JavaScript tutorial sample gallery ( Figure 11.1).įigure 11.4: Getting the clone URL at GitHub. (We’ll be cloning the initial sample repository, so you’ll be able to complete this chapter even if you didn’t follow the CSS tutorial.) In particular, we’ll follow a time-honored tradition in JavaScript tutorials and create an image gallery, which will allow us to display and swap custom images-in our case, a fancy three-column layout ( ).Īfter prepping the gallery (Section 11.1), we’ll learn how to change the gallery image (Section 11.2), set an image as “current” (Section 11.3), and change the image title and description (Section 11.4). This makes it easy to track changes, collaborate with team members, and maintain a history of the code.Learn Enough JavaScript to Be Dangerous: Write Programs, Publish Packages, and Develop Interactive Websites with JavaScriptĪs a final application of our newfound JavaScript powers, in this last chapter we’ll build on the sample application developed in Learn Enough CSS & Layout to Be Dangerous ( ). Developers can create a new version of the code, known as a commit, and add a message describing the changes made in that version. Version control systems, such as Git, allow developers to store their code in a repository that tracks every change made to it. It is an essential tool for software development as it enables developers to keep track of changes made to the codebase, collaborate with team members, and revert to previous versions of the code if necessary. Version control is a system that allows developers to manage changes to software code and track its evolution over time. Whether you're working alone or in a team, understanding and implementing best practices for managing version control with Git can help streamline your workflow, improve code quality, and ensure that your projects are delivered on time and with high quality.īest Practices for Managing Version Control with Git Git is a widely-used and powerful tool for version control that provides a robust and flexible set of features for managing code changes. For software developers and teams, this means that managing version control is crucial to keep projects organized, efficient, and error-free. In today's fast-paced world, technology is constantly evolving and changing.
