Encountering the error message "index.d.ts is not a module" when using TypeScript typings

Question

Encountering the error message "index.d.ts is not a module" when using TypeScript typings

When I try to use the code below, I encounter the error File node_modules/@types/webrtc/index.d.ts is not a module:

import * as webrtc from "webrtc";
const peerConnection1 = new RTCPeerConnection();

I have installed the typings using npm i @types/webrtc --save-dev. Although Visual Studio Code shows type annotations when hovering over RTCPeerConnection, running tsc or webpack with ts-loader throws an error.

In an attempt to solve this issue, I mistakenly tried npm i webrtc --save, but it made no difference. My main goal was to acquire the typings, as WebRTC is available in the browser without needing a package (aside from support considerations).

The index.d.ts file simply references two other files containing interfaces. I thought of removing

import * as webrtc from "webrtc";

and hoping that TypeScript would still recognize the typings in some way. However, since I exclude node_modules in my TypeScript config file, this approach is not feasible and results in RTCPeerConnection being unrecognized.

Even adding

/// <reference src="node_modules/@types/webrtc/" />

did not resolve the issue, as tsc outputs Invalid reference directive syntax.

You can find a repository showcasing a simple reproduction of this problem on GitLab here. As I am not very familiar with acquiring TypeScript typings, I apologize for any mistakes I may have made along the way.

When it comes to webrtc, it's important to remember that it is integrated within the browser itself; you're attempting to import it as a module which may cause issues. The solution is simple - just import the (typings) library like so:

import "webrtc";

If you encounter any problems, consider adding "moduleResolution": "node" in the compiler options.

On the other hand, you can utilize the "types": ["webrtc"] compiler option and let the compiler handle the loading of those types automatically for you.

Answer №3

If you want to incorporate "webrtc" into your TypeScript project, consider adding the following code snippets:

"types": ["webrtc"]

to your tsconfig.json. Alternatively, you can use

/// <reference types="webrtc" />

within your source files. Here's an example implementation in your tsconfig.json:

{
    "compilerOptions": {
        "target": "es5",
        "sourceMap": true,
        "noImplicitAny": true,

        "types": ["webrtc"]
    },
    "exclude": [
        "node_modules"
    ]
}

This configuration directs TypeScript to include the necessary 'webrtc' declarations in your build process.

There is no requirement for importing anything; simply execute the following steps:

npm install --save @types/webrtc
Modify tsconfig.json -

"types": [ "@types/webrtc" ]

When I encountered this issue, it was due to an error message stemming from an index.d.ts file that had been created by the TypeScript compiler.

The root of the problem lay in my failure to include any import or export declarations in the original source .ts file. During the transition from .js to .ts, I had removed the initial module.export = {…} portion and had yet to replace it.

This excerpt from the documentation clarifies the concept of a ‘module’ (emphasis added):

In TypeScript, similar to ECMAScript 2015, any file with a top-level import or export is identified as a module. Conversely, a file lacking such declarations is handled as a script that exposes its contents globally (and therefore to modules).

By including an export statement for the elements intended for exporting, the index.d.ts file transformed into a module, resolving the error.

/// <reference types="@types/<your_types_module>" />

Deciding whether to include this reference will depend on your specific build and style requirements, but it could serve as a simple (albeit unrefined) solution.

The reason for the error was that I had forked a library and renamed it in the package.json file, but forgot to update this line in its .d.ts file (the one referenced by the "types" key in package.json):

declare module "package-name" {

Instead of:

declare module "my-forked-package-name" {
