IntelliSense for Cypress library

[NormalCrazy000]

Reading through the documentation, I can't understand why it is necessary to put the reference to the Cypress library inside jsconfig.json/tsconfig.json to use IntelliSense on VSCode(in addition to the Triple slash directives mode) and it is not possible to use package.json. Is there any trick that allows this?
Thanks

IntelliSense in VS Code is driven by the TypeScript language service, which reads tsconfig.json/jsconfig.json — not your project’s package.json. There’s no package.json field the language service consults to inject global types, so there’s no trick to move it there.

The confusion is that the types field does matter, but only for a package’s own declarations: /// <reference types="cypress" /> resolves node_modules/cypress/package.json → types/index.d.ts. Your project’s package.json can’t register those Cypress globals (cy, Cypress, expect) for the editor.

The three supported ways (all editor-side):

// 1. per-file
/// <reference types="cypress" />

// 2. jsconfig.json (JS projects)
{ "include": ["./node_modules/cypress", "cypress/**/*.js"] }

// 3. tsconfig.json (TS projects)
{ "compilerOptions": { "allowJs": true, "types": ["cypress"] }, "include": ["**/*.*"] }

For project-wide coverage without per-file directives, use "types": ["cypress"] in tsconfig.json/jsconfig.json.
