Can I import *.d.ts instead of require it?
提问by Avol
I have some module libin node_modulesand I want to use it.
I wrote lib.d.tsfor this.
我有一些模块lib中node_modules，我想使用它。我为此而写lib.d.ts。
Files looks like:
文件看起来像：
/src/
main.ts (imports `lib`)
/types/
lib.d.ts
In file main.tsI can write this code:
在文件中，main.ts我可以编写以下代码：
/// <reference path="../types/lib.d.ts" />
import {some} from 'lib';
And it works.
它有效。
But when I try to use import for ambient declaration file:
但是当我尝试对环境声明文件使用导入时：
import '../types/lib';
import {some} from 'lib';
it compiles without errors, but in resulting JS I can find require for this file:
它编译时没有错误，但在生成的 JS 中，我可以找到这个文件的 require：
require('../types/lib');
const lib_1 = require('lib');
With error in runtime of missing file ../types/lib–
it's just an ambient declaration file without resulting file.
丢失文件的运行时出错../types/lib——它只是一个环境声明文件，没有结果文件。
Why compiler did not remove import of *.d.ts file?
Can I use import somehow, or I must use reference instead?
为什么编译器没有删除 *.d.ts 文件的导入？
我可以以某种方式使用导入，还是必须使用引用？
Solution:
解决方案：
If you don't want to use referencedirectives,
you can just add required *.d.ts to files,
included by your tsconfig.json.
如果您不想使用reference指令，您可以将所需的 *.d.ts 添加到 tsconfig.json 包含的文件中。
My tsconfig.json was:
我的 tsconfig.json 是：
{
"compilerOptions": {
"module": "commonjs",
"target": "es2015",
"lib": ["es2016"],
"noImplicitAny": true,
"noImplicitReturns": true,
"noImplicitThis": true,
"strictNullChecks": true,
"noFallthroughCasesInSwitch": true,
"noUnusedLocals": true,
"noUnusedParameters": true,
"noEmitOnError": true,
"newLine": "LF",
"forceConsistentCasingInFileNames": true,
"removeComments": true,
"declaration": false,
"sourceMap": false,
"outDir": "../build",
"types": [
"node"
]
},
"files": [
"index.ts"
]
}
Early I tried to add my .d.ts to typessection, but in this case
tcs is trying to find this file in node_modules/@types directory.
早期我尝试将我的 .d.ts 添加到types部分，但在这种情况下 tcs 试图在 node_modules/@types 目录中找到这个文件。
After suggestion I tried to add file in filessection:
建议后，我尝试在files部分中添加文件：
"files": [
"index.ts",
"types/lib.d.ts"
]
It's works and seems as a good solution.
它有效并且似乎是一个很好的解决方案。

You don't have to importan ambient definition file.
您不必import使用环境定义文件。
You can manually /// <referenceit. But the right way is just to make it available for the compiler through the file tsconfig.json.
你可以手动/// <reference它。但正确的方法是通过文件使其可供编译器使用tsconfig.json。
An example of tsconfig.jsonthat includes anything but node_modules:
一个例子tsconfig.json包括但不包括node_modules：
{
"compilerOptions": {
"module": "commonjs",
"target": "es5"
},
"exclude": [
"node_modules"
]
}
