How to get the websocket provider from ganache-core/ganache-cli
September 9, 2020 at 4:10pmHow to get the websocket provider from ganache-core/ganache-cli
September 9, 2020 at 4:10pmHey guys,
so this is what my set up is currently
const ganache = require('ganache-core')const options = {...ws:true...}const server = ganache.server(options)server.listen(8545)return server.provider
this returns the web3provider instance, is there anyway I can modify the return statement to return the websocket provider?
or do I manually have to write in
ws://localhost:8545 everytime?Answer appreciated, thanks

ganache core/cli host and port are setup by default to localhost(0.0.0.0 for docker) and 8545, you can also change the port using the options object, or -p on the cli. (there is an -h flag for the host also on cli). If you don't want to write it every time you can always set an env var, or use the truffle-config.js when using truffle.
from what i have read on the ganache's code, it does not use WebsocketProvider as Web3 but their own Provider class. I am not really sure what is the use case, but you can still ganache provider to inject it to the Web3.
const provider = ganache.provider(options)const web3 = new Web3(provider)
hope it helps

The docs say that the
ws option set to true "enables a websocket server". I assume this means that what is returned is a websocket provider. ws is also true by default.Did that answer your question? I'm not sure what you mean by "manually write in ..." above, can you elaborate a bit?
