Where are the Cypress types physically located?

If you are working with TypeScript and using Cypress for your end-to-end testing, you might be wondering where the Cypress types are physically located. TypeScript types provide static type checking and editor support, making it easier to write robust and error-free code. In this blog post, we will explore the different locations where you can find the Cypress types.

1. Cypress NPM Package

The first and most common location to find the Cypress types is within the Cypress NPM package itself. When you install Cypress as a dev dependency in your project, it includes the necessary type definitions along with the core library. The types are located in the “types” directory of the Cypress package.

To access the Cypress types, you can import them using the following syntax:

import { Cypress } from 'cypress'

This will import the Cypress types and make them available for use in your TypeScript files.

2. DefinitelyTyped

DefinitelyTyped is a repository for high-quality TypeScript type definitions for popular JavaScript libraries and frameworks. If you cannot find the Cypress types within the Cypress package, you can check DefinitelyTyped for an external type declaration.

To install the Cypress types from DefinitelyTyped, you can use the following command:

npm install --save-dev @types/cypress

Once installed, the Cypress types will be available for use in your TypeScript files.

3. Custom Type Declarations

If you prefer to have more control over your type declarations, you can create custom type declarations for Cypress in your project. This allows you to define specific types or extend existing types to suit your needs.

To create a custom type declaration file for Cypress, follow these steps:

Create a new TypeScript file with a “.d.ts” extension (e.g., “cypress.d.ts”).
Declare the types you need for Cypress within this file.
Make sure the file is included in your TypeScript project configuration (e.g., tsconfig.json).

Here’s an example of a custom type declaration file for Cypress:

// cypress.d.ts

declare namespace Cypress {
  interface CustomCommandOptions {
    // Define custom command options here
  }
}

With this custom type declaration file, you can extend the existing Cypress types or define new types specific to your project.

These are the three main locations where you can find the Cypress types for TypeScript. Whether you choose to use the types provided by the Cypress package, install them from DefinitelyTyped, or create custom type declarations, TypeScript can greatly enhance your development experience when working with Cypress.

Happy testing!
