@types/web - Types for the DOM and most web-related APIs

This module contains the DOM types for the majority of the web APIs used in a web browser.

The APIs inside @types/web are generated from the specifications for CSS, HTML and JavaScript. Given the size and state of constant change in web browsers, @types/web only has APIs which have passed a certain level of standardization and are available in at least two of the most popular browser engines.

@types/web is also included inside TypeScript, available as dom in the lib section and included in projects by default. By using @types/web you can lock your the web APIs used in your projects, easing the process of updating TypeScript and offering more control in your environment.

Installation

To use @types/web you need to do two things:

  1. Install the dependency: npm install @types/web --save-dev, yarn add @types/web --dev or pnpm add @types/web --dev.

  2. Update your tsconfig.json. There are two cases to consider depending on if you have lib defined in your tsconfig.json or not.

    1. Without "lib" - You will need to add "lib": []. The value you want to add inside your lib should correlate to your "target". For example if you had "target": "es2017", then you would add "lib": ["es2017"]
    2. With "lib" - You should remove "dom".

That's all.

SemVer

This project does not respect semantic versioning as almost every change could potentially break a project, though we try to minimize removing types. @types/web follow the specifications, so when they mark a function/object/API/type as deprecated or removed - that is respected.

TypeScript Version Support

Prior to @types/web the web APIs were deployed with a version of TypeScript, and backwards compatibility has not been a concern. Now the web APIs and TypeScript can be de-coupled, then we expect to eventually hit a point where we take backwards compatibility in mind. For now, @types/web officially supports TypeScript 4.4 and above. It very likely will work with TypeScript versions much earlier that that however.
