Deprecated warning with Express

[lemonCMS]

I am using the latest history version

"history": "1.12.1",

With Express i am getting the following warning

Warning: createLocation is deprecated; use history.createLocation instead

In the clientside code this was easy to fix

const history = require('history');
const historyObj = history.createHistory();

historyObj.createLocation(....)

When you try to run this code with express you will get the following error

[1] [piping] error given was: Error: Invariant Violation: Browser history needs a DOM

So how can we use createLocation with express?

Same problem for me

In a non-DOM environment (like node) you need to use a "memory history", not a "browser history".

const history = require('history');
const historyObj = history.createMemoryHistory();

historyObj.createLocation(....)

This is because browser history needs to setup a listener for the popstate event. But memory history just keeps everything in memory.
