Proposal: GraphQL editor deeplinking standard

GraphQL has wide editor support, and projects like GraphiQL and GraphQL Playground have ensured that there is a proliferation of different web editor instances.

An invariable feature that we have already seen rolled out on an adhoc basis (e.g. https://www.onegraph.com/graphiql) is the ability to generate a link within a graphql editor that allows easy sharing of queries between users.

Such links are also useful from a documentation perspective, in that they allow users to easily open, edit, and run queries referenced in the documentation by simply clicking a link, improving the user experience.

A standardized format for these links would be a boon not only to online editors, but also IDEs, in that a given IDE would be able to register an app uri handler for GraphQL, making it very easy to implement features such as "open in local ide".

The format would not necessarily be restricted to just queries, it could also be potentially useful for service discovery, perhaps referencing an introspection endpoint, or schema SDL.
