Previously, we were planning to offer two kinds of APIs in "Apollo Server 2":
middleware functions just like in 1.0, and the new ApolloServer class. We have
not yet implemented ApolloServer for all of our supported web frameworks, so
this meant that the 2.0 version of modules such as apollo-server-koa (which does
not yet have an ApolloServer class) offered very little benefits over
apollo-server-koa@1.0 (as most of the benefits of 2.0 come from ApolloServer).
This is confusing. We are going to improve the current registerServer API so
that there's no real benefit to using a separately-exported middleware directly
rather than creating an ApolloServer and applying it to your web framework. So
the AS 2.0 API will just be ApolloServer. This means it doesn't make sense for
us to publish 2.x versions of the packages that don't yet support this API.
So this commit removes support for the following web frameworks: Adonis, Azure
Functions, Koa, Lambda, Micro, and Restify. (We leave in place Express, Hapi,
and Cloudflare workers.)
This isn't because we don't like these frameworks and don't want them to work
with Apollo Server 2.0! We would love to see each package resurrected and an
ApolloServer implementation built, either during this current 2.x beta phase or
after the official 2.0 release. Deleting these packages for now makes it more
clear which frameworks support 2.0 and which don't, rather than existing in a
state where apollo-server-express@2 has ApolloServer and apollo-server-koa@2
does not.
