How to write a typescript definition file for a node module that exports a function?

Question

Consider, for the toml node module I can simply use: ``` // toml.d.ts declare module TOML { export function parse(value:string):any; } declare module "toml" { export = TOML; } ``` Then: ``` /// import toml = require('toml'); toml.parse(...); ``` However, what about node module that export only a single function, such as 'glob' (https://github.com/isaacs/node-glob). The node usage of this module would be: ``` var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); ``` You'd naively expect you could do this: ``` // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ``` ...but because typescripts 'import' semantics are a bit strange, it seems you can only use the 'import .. = require()' statement to alias modules. Trying to call: ``` /// import blog = require('glob'); ``` Results in: ``` error TS2072: Module ca…

Accepted Answer

Use `export =`.

Definition:

```
declare module 'glob' {
  function globs(paths: string, options: any, callback: (err: any, files: string[]) => void): any;
  export = globs;
}
```

Usage (with esModuleInterop enabled):

```
import glob from 'glob';
glob("*.js", {}, (err, files) => { });
```
