is there is a way to install cypress without installing electron?

[eugene-matvejev]

Hello

thanks for awesome tool!

I got a question if there is a chance to install cypress without electron?

it would be very useful for docker

i heard that cypress will support alpine in 4.0 so it could be an improvement 'out-of-the-box'

I got POC:
https://github.com/eugene-matvejev/battleship-game-gui-react-js/blob/master/cypress.Dockerfile

you can try it out im my repository by cloning it, and using make cypress

λ docker images -a

I am sure cypress/browsers is well optimised, but npm i, if it got cypress pre-installed, got another 400mb into image, or i do something wrong? - think it is because it pulls some binaries which aren't needed?

Hey, what is your goal in installing cypress without electron? Just want to understand the motivation clearer? Size optimization? Want to install your own Electron version?

Gonna add a comment on this as for us it would be to install our own version of electron. We are packing our app with electron 4.0.0 so would like to test against it

@jennifer-shehane , I try reduce size, and I try fix an issue when you work for corporations,

it is doable for corporations adopt few docker images in their private docker repositories, but it is close to impossible to allow fetch stuff from github/npm - and it is a big pain

don't get me wrong, I am big advocate for cypress anywhere where I go for work, but I just need a bit more help with these bits, as for example, I know unix environment good enough to setup proxies, but many people struggle and just hate tools which they can't install

the idea is, to somehow reduce docker image size, and reduce downloads,
as if cypress can execute using chrome, why it need electron? is it somewhere in dependencies? does cypress runner require electron? may be I don't understand something

@dmce I am looking forward to it.

eventually, I am doing my repository, as I talk on London IT events, I want promote this tool, as I found it very good :) but people will face issues like i mentioned above as many of them work in corporate environment, which is most of time is behind 1001 firewalls and proxies

There's an issue open to separate the installation of Electron from Cypress here: #3899

Some comments on how and why we couple Cypress with Electron today: #2761 (comment)

Also an issue on Cypress - to - Electron versioning: #3228

Please feel free to close this issue if you feel any of the others covers what you'd like.
