To reproduce:

CMD

md test
cd test
md src
npm init -y
npm i @types/node
tsc --init
code . --disable-extensions

//tsconfig.json

{
	// these are default
	"compilerOptions": {
		"target": "es5",
		"module": "commonjs",
		"strict": true,
		"esModuleInterop": true
	},
	// additional
	"files": [
		"./node_modules/@types/node/index.d.ts"
	],
	"include": [
		"src/**/*.ts"
	],
	"exclude": [
		"node_modules"
	]
}

//src/index.ts

const fs = require('fs')
var dirList = fs.| //<- **_NO INTELLISENSE_**

Or maybe I'm doing it wrong?

This works if you write:

import fs = require('fs')

I don't know if using plain require was ever supported

@Andy-MS
a.ts

import fs = require("fs");
namespace G {
    export let a = 0;
}

b.ts

G.a // error 

I want use namespace as global(merger all file in one file). not single module. but if use "import fs = require('fs')" in "a.ts", "b.ts" can't use G. if use "const fs = require("fs")", it's work.

"const fs = require("fs")" no intellisense in vscode, webstorm have intellisense. it's confuse me.

A file can not be both a global script and a module. it is either one or the other.. import .. = require(..) only works for modules. if you are using namespaces, then you should do something like:

const fs: typeof import ("fs") = require("fs");

@weswigham do we have an issue for higher-order import types?

[weswigham]

I don't think one's actually been opened yet, no.

[mhegazy]

We should then. we should collect such use cases.

[WangPengJu]

const fs: typeof import ("fs") = require("fs");

[ts] Cannot find name 'import'.
[ts] The left-hand side of an assignment expression must be a variable or a property access.

@mhegazy
i just want intellisense, use namespace. as global

[weswigham]

@WangPengJu import types are only in the nightly right now, as we've yet to cut a release since adding them.

[WangPengJu]

ok. i can wait @weswigham
which one?
