Editor to share with you how to install and compile Typescriptrh, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. CDM command tool

Npm I-g typescript

Create a Typescript file of app.ts (the file name is random), and then write in it

((num) = > {console.log (num + 1)}) (2)

Type on the CMD command line

Tsc app.ts

Fourth, after the third part is executed, it will generate an app,js file, and then the contents will look like this.

(function (num) {console.log (num + 1);}) (2)

Of course, we can't compile like this every time, the best way is to compile while writing:

First, execute on the command of CMD.

Tsc-init

Generate a tsconfig.json file, this file can be set with more configuration, there are detailed comments, you can take a look.

Second, then execute it in the CMD command tool (of course, you don't have to generate tsconfig.json files)

Tsc-watch app.ts

It can be compiled all the time.

If you want to generate a map file, you can do this:

Tsc-watch app.ts-sourceMap

If you want to compile the .ts file in the full directory, you can write it this way. When Typescript is compiled into js, it will be compiled in the same directory and does not need to be set up again.

Tsc-watch-sourceMap

If you want more information, you can check it out on Typescript's website, but I won't say much here, because there are too many parameters set (about 80).

The above is all the contents of the article "how to install and compile Typescriptrh". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
