如何在angular2项目中创建tsconfig.json文件？

Question

I have created one angular2 project using npm. I was referring this link: Angular2 Tutorial

I succeessfully created the package.json file using npm init command. But I didnt find any command to create tsconfig.json file. I am not sure that should I create that file using command or using editor? Thanks in advance.

Answer 1

使用init选项调用TypeScript编译器将在当前目录中创建新的tsconfig.json

tsc --init

Answer 2

To complement the Vadim's answer, the tsc command is available after having installed TypeScript:

$ npm install -g typescript

You can also use some parameters with this comment:

$ tsc --init --experimentalDecorators
      --moduleResolution node --target ES5
      --sourceMap --module system --removeComments

This way, you're very close to what Angular.io uses for this samples.

You can then remove the outDir and rootDir entries if not needed. Moreover an entry isn't generated this way. You can add it manually in the generaed tsconfig.json file.

"emitDecoratorMetadata": true

Hope it helps you, Thierry
