Compatibility with Gatsby V3

[jaymdq]

I tried to install this plugin in a Gatsby V3 project with no luck.

npm ERR! Could not resolve dependency:
npm ERR! peer gatsby@"^2.13.80" from gatsby-theme-apollo@3.0.3

This may help?

Good catch @jaymdq. Just changed the gatsby-theme-apollo peer dependency from ^2.13 to >=2.13, so you shouldn't see that error anymore. Hope this helps!
