So now that we’ve talked about what Webpack is, we’re going to work on adding Webpack to our client-side code.
All right, so the first thing that we’re going to do, is let’s go ahead and make a new folder, we’re actually going to go ahead and call it client. So this is going to keep, this will contain all of our client-side logic. For now, we will not drag the index.html file in our assets folder in there, we will do that later.
So, to actually use Webpack, we need to install it as a dependency, so the first thing we should do is actually create a package.json file for our code. So, if we go ahead and switch over to our Terminal, let’s go ahead and go cd into the client folder, and let’s go ahead and run the npm init command.
So, if you recall, the npm init command is going to walk us through creating a package.json, so for a package name, we’re going to go ahead and just leave it as client, we’ll do 1.0, for our version, description we’ll just do client side code for zenvo mmorpg. For our entry point, we’re going to go ahead and do source and then index.js, test command, we’ll go ahead and just leave that a blank for now, we won’t worry about git repository or keywords, and as for author, I’m going to go ahead and put my name, you can go ahead and put yours, and then for our license, we’re just going to go ahead and leave that as the default license.
And then, we just need to go ahead and verify the information we put in. Yes, and then now, if you go ahead and check, we should have, inside our client folder, our package.json.
Perfect, so now, we can go ahead and start, actually installing some of our dependencies, so do go ahead and install Webpack, we just need to do npm install, –save, but instead of just -save, we’re going to go ahead and do save-dev, and what this will do, is it’s going to install this dependency as a dev dependency, which shows that it’s needed, well, for development, but it’s actually not needed in our production code. We’re going to go ahead and do webpack, we’re going to do webpack-cli, and then webpack-dev-server. And then we’ll go ahead and hit Enter to start installing your dependencies, so, webpack-cli, webpack-dev-server, are additional packages that are helpful while you are working with Webpack,
So, what Webpack test server will do, is it’s going to run a development server that’s going to bundle and run our code as we’re working on it, so that way we can actually test our changes in real time, where if we’re just doing the webtag build, we would actually have to build our source code every time we make a change, and then run another server to test it. That’s why webpack-dev-server is really nice, is because we can actually do it while we’re developing. And webpack-cli is just a set of commands for developers that makes it very easy to set up a custom Webpack project.
All right, perfect, so now these are installed. The next package we’re going to go ahead and install is we’re going to go ahead and install Phaser. So, currently, we have our Phaser library included with our source code, since we’ll be switching to Webpack, we can install Phaser as a dependency, and then reference it, and then when our code gets bundled, Phaser will be bundled with our code, and we don’t actually have to include that file separately.
So we’re going to go ahead and do npm install -save and we’ll do phaser, and another benefit of doing this, is we can easily upgrade our version of Phaser, without having to download and save the source code, and then upload it into our server, and since we are including it as a dependency, we can easily update our dependency to get the newest version, re-bundle our code and push it up to our server, and then we’ll be using the new version of Phaser.
All right, so now that Phaser installed, let’s go ahead and switch back to our code editor. And you will see our package.json’s been updated with our dev dependencies and our regular dependency.
