![]() ![]() ![]() Now that is complete aside from everything else we're going to go into. There are sometimes where on a daily basis I will need to delete a note module directory from one project or another one depending on how big they get and how many conflicts that might arise.Īnd so I simply wanted to show you that you should think about these as temporary and when we get into topics such as version control a very important concept is you should never check in your node modules into version control. And the reason why I went through that exercise is because this is something I've had to do constantly. All of those various code libraries and those packages. It is going to go through the entire set of dependencies and as you can see it's already doing it and it's going to pull down from the NPM registry. And as you can see node_modules is gone.īut if I run npm install once again the same process is going to occur. Now it's going to be quite a few items as you can see there so many files it's over 10,000 or so files. I'm going to delete it and I'm also going to go and empty my trash. So even though it has all of this code that you can simply get rid of it and just so you do not think I'm lying to you I'm going to open this up and as you can see we have node modules right here. Now one thing I want to point out about how this works and it's very important because if you plan on doing any real-world javascript development you're going to run into this, your node modules directory can be a completely thrown away kind of tool which means that because it can be generated on the fly if you run into any kinds of dependency issues or bugs where say one of these packages interferes with another one it is no problem at all to simply delete this file from your computer and then run npm install once again and it will create this new modules directory. And each one of these different packages is going to be brought down in your application and all of the code is going to be stored in this node modules directory. And as you can see it's going to create node modules directory. It's going to go through all of our dependencies both our dev dependencies and are our regular production dev dependencies right here. ![]() Now what is going to go on here is it's going to go through this process is going to go through our package.json file. Now notice we do not have a dependency called momentjs listed here and that is going to be the one that you can see here in the browser that we were going to implement.īut before we do that I'm going to open up the terminal and type npm install. Now I want to first go into the package.json file and you'll see all of the dependencies that we currently have. Now I'm going to CD into that directory and now that I'm there and let me also open that up inside of Visual Studio Code so I'm gonna hit command o click on PackageProject, simply click openĪnd then it is going to open the entire project and you can see we have all of our code right here. Once again I want the es6-starter and for this one, we're simply going to call this PackageProject and that is all we have to do. So I'm going to type in js-generate and this is going to ask me what kind of project I want. ![]() And so if you're in the terminal simply go to whatever directory that you want to use it via the code directory or projects directory go to wherever you want to create your new project and we're going to go through the process on building another project and generating it from scratch. And maybe my naive post will generate other posts that will help you.The first thing I'm going to do is I'm going to change back into the desktop. I don’t know Rails that well but did get caught up in the Webpacker a year or two ago. Many good posts and YouTube tutorials have been done about Webpacker in Rails, but they all seem to take slightly different approaches and the official documentation hasn’t kept up. Since Webpacker is relatively new people have different approaches on how to implement it and you’ve discovered that. Webpack VS Sprockets - The Lean Software Boutique will give you an idea of what’s involved. A short history would be Sprockets, Webpacker and now Rails ES6 based replacement for webpacker - #2 by juansecaro, a post written by the creator of Rails, DHH. Rails struggles with how to deal with JavaScript. You’ve found a major problem with Rails at the moment. GitHub - rails/webpacker: Use Webpack to manage app-like JavaScript modules in Rails which doesn’t acknowledge the /javascript folder. This app appears to use Webpacker hence /app/javascript/. There are now several ways to manage javascript files and depending on how your Rails app was set up, the javascript folder may be somewhere else. ![]()
