Should the console warning stay

[MacFJA]

@boatilus, I see that you fork the lib to remove the warning.

Do you mind to explain the use case that make you want to remove the warning ?

I know that in SvelteKit the warning appear quite often if it's used in the server side rendering
(but persistent store shouldn't be avoid been used in the server side 🤔 )

I'm not against removing it (or to add a flag to disable the console.warn).
Feel free to open a PR with the changes 🙂

Hey MacJA. Thanks for this library!

You're spot on -- the sole purpose of removing the warning messages is because it pollutes SvelteKit's output. There may be a technique to just suppress the output in svelte.config, but I figured it may be easier for my purposes to fork it.

It's probably best that the warning stays, but putting it behind a flag may be a good option.

@boatilus I push a PR (#10) about that:

• Warnings are displayed only once (mainly for server side)
• A detection of production mode have been added (if in production mode, no warnings)
• A flag (disableWarnings()) have been added to disable console.warn
