Typescript types issues

[alindesign]

Current behavior:

I have got some types error usign cypress with typescript, after some investigations and alot of tries to add these types on my tsconfig.json, nothing worked 😢 i have decided to change references from cypress/types/index.d.ts so:

// These references
/// <reference types="blob-util" />
/// <reference types="bluebird" />
/// <reference types="minimatch" />

// Transformed into
/// <reference path="./blob-util.d.ts" />
/// <reference path="./bluebird.d.ts" />
/// <reference path="./minimatch.d.ts" />

After this changes, everything worked normally 😞
There is the PR: #1622

Thanks in advance and sorry for my english :/

Great, can you make a small repo reproducing the problem? Like a fork of https://github.com/cypress-io/cypress-test-tiny for example? I just want to see the problem myself

also, @NicholasBoll what do you think?

The errors you're seeing makes sense - blob-util, bluebird and minimatch are the three dependencies that aren't namespaced (global definition). I can reproduce and your suggested solution fixes the issue. I'm pretty sure it worked at one point. Maybe the existing code used to work, but wasn't supposed to and a TypeScript change fixed that loophole.

// as it is right now
Cypress.Promise // any

// with the suggested change
Cypress.Promise // typeof Bluebird

I don't think I noticed when this started breaking because I've had skipLibCheck enabled (I've had issues with other namespaces colliding).

#1622 has been merged, but didn't have a reference to this issue so it didn't automatically get closed. Can this issue be closed now?

good catch @NicholasBoll closing this
