Trouble connecting to Gun when server is spun up inside of Electron

mboperator commented 5 years ago

Context

I'm building a decentralized story telling desktop application using Electron. The Electron app is comprised of a server and a client.

The client is a React app. The server is a node server running Express with Gun middleware.

Package Versions

"express": "~4.16.1"
"gun": "^0.2019.726"
"electron": "4.0.8"
"node": "12.10.0"

When running the server outside of Electron in dev mode, everything works fine:

My Electron app is unable to hit the Gun websocket endpoint when the server is run from within Electron:

The server is able to start properly inside of Electron. http://localhost:7000 shows my hello world page.

This is the Electron server:

This is how I'm spinning up my express server inside of Electron:

Running with different Node versions (8, 12). No dice.
In production, the client app's origin changes from localhost to file so I tried adding cors. No dice.
I was getting build errors from SEA + node-webcrypto-openssl so I switched gun to use @peculiar/webcrypto. Still not working.

If anyone has any example of an Express server running Gun inside of Electron that would be a huge help.

Thanks in advanced!

Fixed my own issue. The return value of server.listen needs to be passed into the Gun constructor.

Sorry about that! Glad you got it working.
