ApolloServer builds in graphql-playground rather than graphiql, so we no longer
provide middleware for serving GraphiQL.
If this turns out to be an unpopular choice, we can always add support for
graphiql instead of graphql-playground back in later.
We prefer graphql-playground because it allows you to enter HTTP request
headers, view query history, and explicitly supports graphql@0.13.
runQuery currently takes a `query` argument that is either a string or a
DocumentNode. This means that it's possible to accidentally support syntax we
don't mean to. For example, if you happen to send a JSON-serialized DocumentNode
over the wire, we'll happily execute that, and you'll believe you're using
GraphQL even though you really aren't --- until you try to use some other
GraphQL tool that expects to see the GraphQL query language rather than
graphql-js ASTs.
Additionally, GET requests parse their queries in runHttpQuery rather than
runQuery, leading to inconsistent error handling semantics on parse failures.
Simplify the runQuery API (which is technically exported though intended to be
mostly internal) to take in either a parsedQuery or a queryString argument. The
main use case for knowing about these parameters is if you're using formatParams
with OperationStore; its docs and tests have been updated to reflect this.
Stop parsing queries in runHttpQuery; instead, ensure we throw the right error
for mutations-over-GET by passing the error to throw into runQuery.
Stop accidentally supporting graphql-js ASTs on the wire --- but throw an
informative error when you do so.
This backwards-incompatible change is intended for apollo-server-core 2.0.
Apollo Persisted Queries is a standard for sending queries as short hashes
instead of full strings, designed to work well with GET requests. It is
implemented by servers including the Apollo Engine Proxy, and by the
apollo-link-persisted-query client.
A common configuration is to set up persisted queries on production servers but
not in development. It is still convenient to leave apollo-link-persisted-query
always on, though. While apollo-link-persisted-query can detect that servers
don't support PQs, it works better if the server actually says it doesn't
support the PQ, instead of trying to process a request without a query and
potentially printing a confusing stack trace. This commit makes apollo-server
directly return PersistedQueryNotSupported instead of allowing confusing stack
traces to occur.
This change was introduced by the changes in apollographql/apollo-server#802
but first showed its head in apollographql/apollo-server#908. The reason that
violations in new type definitions aren't being found until subsequent PRs
isn't entirely clear but, ignoring that CI-related annoyance, the problem
itself here is very concrete.
It traces back to a major version update to `@types/mocha` via [Exhibit A],
which makes it unacceptable to return anything besides a `Promise` or
_nothing_ from a Mocha test factory.
I agree with this change in principle, since generally speaking there can be
multiple `expect` statements in each test and there is no particular reason
that the last one's value should be getting returned as Mocha doesn't do
anything functional with it.
More than anything, this seems like an artifact of an ESLint rule which
mandated that the last value in a function be returned, à la CoffeeScript or
other languages.
This will fix the failing tests on apollographql/apollo-server#908 and other
PRs currently in-flight.
Exhibit A: https://github.com/DefinitelyTyped/DefinitelyTyped/pull/24301
This fixes the default behavior for class-based contexts by also cloning the prototype, and it allows you to customize per-operation behavior by passing in a function as context.
