Installing Cypress with CYPRESS_DOWNLOAD_MIRROR and Artifactory

[bluepioupiou]

Current behavior

When setting Cypress in artifactory, and downloading it with CYPRESS_DOWNLOAD_MIRROR set toward this tool, the download script find binary files as 6.8.0 and not cypress.zip and fail. Apparently I can't rename binaries in artifactory.

My artifactory admin tell me to dothis command before but I can't since it's a post action of Cypress
curl –v « https://artifactory.mycompany.fr/artifactory/remote-download.cypress-generic/desktop/6.8.0?platform=win32&arch=x64 » > cypress.zip

I don't really know if it's an artifactory or a Cypress matter but I need help ^^

It seems similar issue to #8825 which was closed with #8877.
Version 7.3.0 now supports CYPRESS_DOWNLOAD_USE_CA env variable which forces cypress to honour ca and cafile properties on .npmrc.

From my own personal experience setting up Artifactory to mirror cypress binary:

• Use Generic repository type pointing to https://download.cypress.io
• In Advanced settings for repository:
  • check "Propagate Query Params"
  • uncheck "Store artifacts locally". See details: https://www.jfrog.com/jira/browse/RTFACT-22459

In summary it is possible to setup Artifactory with self-signed certificate to mirror cypress binaries for different platforms with cypress version 7.3.0.

@minijus's directions get pretty close, but requires unchecking "Store artifacts locally". Without storing artifacts locally, a lot of the benefits of having an internal cached mirror are lost. Each Cypress download would refetch https://download.cypress.io.

Would it be possible to get a new config for the Cypress downloader to use path params? Or have Cypress attempt query params and fallback to path params? That would make it possible to internally cache through JFrog Artifactory.

Thank you! 🙂

curl https://download.cypress.io/desktop.json  | jq

      "url": "https://cdn.cypress.io/desktop/9.1.0/win32-x64/cypress.zip"
    }
  }
}

But Cypress itself still searches for platform and version with query params in a hard-coded manner:

cypress/cli/lib/tasks/download.js

Line 67 in 1ff7839

return `${endpoint}?platform=${platform}&arch=${arch()}`
