why did the entire file change?

Interesting. I'll check if there's a change like line-ending.

Line ending was changed at d719f66. Fixed.

bahmutov

can we add an e2e test where we have a typescript fixture with ApplicationWindow interface with user property? To confirm the TS passes. Alternatively, and maybe even better is to add a recipe to cypress-example-recipes to show users how to add a property to window and have the types work out of the box.

can a PR to cypress-documentation for page https://on.cypress.io/typescript show the ApplicationWindow example AND minimum TypeScript version needed (3.4) in this case?

Can we open an issue documenting this fix and why it's necessary. Also per @bahmutov's comments, it seems like there's a bit more work to do on this PR yeah?

OliverJAsh · 2020-06-29T18:57:25Z

I had a clear description in my original PR, but sadly that was closed: #6624

@OliverJAsh

It's recommended to create an issue before submitting a PR in the contributing guide.

If there is not an associated open issue, create an issue using our Issue Template.

Sometimes, ignoring guides can cause unwanted results. (And I also know that it's really tedious to read every contributing guide before contributing.)

Anyway, I opened an issue at #7856.

sainthkh · 2020-06-30T03:21:08Z

@bahmutov @brian-mann

There are 3 more things to do:

Create AUTWindow type and replace the appropriate Window types in cli/types/cypress.d.ts with it.
Create a new recipe at cypress-example-recipes to showcase out-of-the-box TypeScript, how to check typescript types and ApplicationWindow type extension => feat: Add TypeScript example. cypress-example-recipes#515
Create a new PR at https://on.cypress.io/typescript cypress-doc that the required minimum TypeScript version has been risen to 3.4

brian-mann · 2020-06-30T04:44:01Z

@sainthkh proceed ahead - we are trying to release 5.0.0 in the next day or two and want to get this in.

jennifer-shehane · 2020-06-30T05:26:32Z

@sainthkh cy.window() is not the only command to return the Window, will the other command's definitions be extended? The other commands:

cy.go()
cy.reload()
cy.visit()

jennifer-shehane · 2020-06-30T05:38:28Z

I've opened a PR for the docs to update the min required version to 3.4+ cypress-io/cypress-documentation#2945

Previously this would type error: ```ts cy.window().then(window => window.eval('1')); ```

`globalThis` was added in 3.4.

sainthkh · 2020-06-30T10:05:59Z

It seems that kitchensink needs update after #7782. (CircleCI result link)

I think this is good to go, once merged into v5.0-release we will add testing the recipe cypress-io/cypress-example-recipes#515 PR
