Support both SB 6 & 7

[JesusTheHun]

Is there a way to support SB 6 and 7 with the same package? Or do I need to make a breaking change version?

That's a really good question. There are some breaking API changes so I wouldn't expect a SB7 addon to work with 6.x and vice versa. The addon kit specifies Storybook dependencies as peer dependencies, so they'll come from your Storybook setup.

IMO you'd have to release a new major version of your addon.

I have noticed some changes, but I didn't see any hard breaking changes, meaning that if you check for the SB version at runtime, you should be able to branch your code. I don't know SB have much as you do though, hence this issue. What do you think about code branching ?

[winkerVSbecks]

It depends a bit on how your addon is setup.

There are a few changes that could impact your addon:

• register.js was removed (deprecated in SB 6.5)
• No more default export from @storybook/addons
• @storybook/api has been split into @storybook/preview-api and @storybook/manager-api

@storybook/api is still available in 7.0 but you'll see a deprecation warning.

IMO publish an alpha of your addon and try it out. I would be very interested in the results too.

Otherwise, check out https://github.com/storybookjs/addon-styling It's been set up to publish two versions. 6x on main and 7.0 on next

auto handles that for you by default
