![]() ![]() This is the System.import we requested in the above markup, and the syntax should be somewhat familiar to anyone who has used AMD or CommonJS modules before. If we refresh the browser we should see some errors in the console that app/main.js couldn’t be loaded. Inside the body tag, the markup looks like: Testing ![]() Next, we’ll update the default.html file to bring in System.js, the dynamic module loader installed by jspm, and the config file created by jspm, which tells the loader where to make requests for specific module and libraries. We want jspm to work with a package.json file at the root of the project, but store downloaded packages and configuration in the If there is enough interest, we can look at building and bundling in a future post. The most important answer is the answer to the public folder path (./wwwroot). Using loader Loader files downloaded successfully Verified config file at wwwroot\config.js Which ES6 transpiler would you like to use, Traceur or 6to5? : 6to5 wwwrootĮnter jspm packages folder :Įnter config file path :Ĭonfiguration file wwwroot\config.js doesn't exist, create it? :Įnter client baseURL (public folder URL) : Would you like jspm to prefix the jspm package.json properties under jspm? :Įnter server baseURL (public folder path). Here’s how to answer: Package.json file does not exist, create it? : As you can see below I prefer the 6to5 transpiler over Traceur these days, but note that 6to5 was just renamed to Babel last week. During the questioning you can choose the ES6 transpiler to use. ![]() The init command will ask a series of questions to setup a project.json file (yes, the same project.json that npm uses, unlike Bower which creates it’s own json file). You’ll want to run jspm init from the root of the project, which is one level above the wwwroot folder. Once you have both NodeJs and a command line Git client installed, jspm is simple to setup. Pressing Ctrl F5 should run the application as always, but we’ll need to add /default.html to the URL as the web server won’t find a default file without some extra configuration (see ‘Making default.html the default’ later in this post). Notice the We can create a new default.html file in wwwroot as the entry page for the application. With ASP vNext, the resulting project looks like the following. In VS2015 we’ll start with a minimum set of features by using File –> New Project, selecting “ASP.NET Web Application” and using the “ ASP.NET 5 Empty” template. By integrating package management with a smart script loader, jspm means less work for us. You can write code using today’s JavaScript, or tomorrow’s JavaScript (ES6), and use any type of module system you like (ES6, AMD, or CommonJS). In a nutshell: jspm combines package management with module loading infrastructure and transpilers to provide a magical experience. In this post, we’ll get setup using jspm instead of Bower, and write some ES6 code with CTP5 of Visual Studio 2015. If you’ve been following along with the developments for ASP.NET vNext and Visual Studio 2015, you’ve probably seen the JavaScript tooling of choice for File –> New projects is Grunt and Bower.īut, what if you wanted to use more sophisticated and productive tools, like Gulp and jspm?
