This article is to share with you about how to use TypeScript in ASP.NET. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

What is TypeScript?

TypeScript is a superset of JavaScript that brings object-oriented as well as static types to JavaScript. You can inject JavaScript code into your project without modifying any existing TypeScript code. With TypeScript you can standardize JavaScript code and build your front end in an object-oriented way. TypeScript already supports the popular JavaScript library, making it easier for you to integrate with existing projects, such as Jquery/AngularJS/KnockoutJS/NodeJS. (go to the official website)

TypeScript environment configuration

1. Installation

Npm install-g typescript

two。 Development environment

Personal suggestion is still in Sublime Text, install Better TypeScript through Control Package.

Several main characteristics of TypeScript

1. Static type

TypeScript regulates the declaration of JavaScript variables through static types and provides type checking at compile time.

Here, a class is defined, and a method of getJSON is defined in the class. Here, the parameters passed by the method are defined with static types, and void is returned. If you write in traditional JavaScript, although weakly typed is more convenient, it is not clear about the type of passing parameters. With TypeScript, you can write your front-end code in the same way as CCompact +. To make it clear here, when you are not clear about the type of object, you can use any (dynamic type) instead.

two。 object-oriented

TypeScript brings object-oriented features such as interface/class/module to JavaScript. In addition to standardizing the code, this benefit can also standardize the front-end project structure. In the past, our JS project started with traditional MVC/MVVM because JavaScript was so flexible that the architecture was unable to start. With TypeScript you can integrate your front-end code with object-oriented.

3.ts compiler

The ts file of TypeScript can be compiled into a general JavaScript file through tsc. Of course, you can choose to precompile, or you can choose to compile in real time. It is the same sentence that salted fish and cabbage have their own preferences, depending on their own needs. While I am in the project, I like to use precompilation.

4. Third-party library support (the corresponding TypeScript for third-party libraries can be obtained here)

Now that TypeScript matches the mainstream libraries, you can get it from the link above nuget/. My front-end architecture is basically based on AngularJS/KnockoutJS, basically no big problem. Even more gratifying is the deeper integration (Google+Microsoft) of AngularJS 2.0 and TypeScript.

The above is how to use TypeScript in ASP.NET. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
