Problems arise during the installation of TypeScript typings for .NET Core

After downloading VS2015 community edition, I decided to migrate one of my old MVC projects to .NET Core MVC. I used TypeScript for all the client side code in my old project, but now it's becoming a hassle to set up. Despite configuring multiple JSON config files, I finally got my TypeScript files working. However, I recently added some 'definitleytyped' packages that are not easily visible in the project, and my TypeScript is throwing errors because it can't recognize '$' for jQuery.

I tried searching on Google and found out that I should be using 'typings' instead. I attempted running 'NPM install typings --global', but no matter if I used PowerShell, cmd, or the VS dev command line, 'npm' was unrecognized. I'm feeling stuck and unable to make any progress. Can someone please assist me?

Answer №1

To set up your development environment, first, ensure you have Node.js installed on your machine and then configure Visual Studio to use this version. You can follow the steps outlined in this tutorial.

Next, open a command prompt and install the typings CLI by running the following command: npm install typings --global

Finally, make sure to add any necessary configuration files (such as tsconfig.json) and everything should be ready to go.

Answer №2

Step 1: Begin by installing npm from https://nodejs.org

Step 2: Next, install typings using the following command:

npm install typings -g

Step 3: Adjust the settings in Visual Studio to prioritize your PATH when working with npm installations. This is crucial for smooth functioning as VS now includes npm integration.

Navigate to Tools -> Options -> Projects and Solutions -> External Web Tools

Select $(PATH) and use the arrows on the right corner to move it to the top row.

Step 4: Navigate to your project directory using the command cd and then run typings install jquery --save

Step 5: By doing this, you will obtain the necessary typing definition for utilizing jQuery within a .ts file. Substitute JQueryStatic instead of using $.

Best of luck!
