the order of the files give different results

[zvictor]

I am facing errors while using graphql-import that vary depending on how I am calling the importSchema function.

First, I created a directory with 3 files, all containing valid graphql schemas:

• base.qll
• User.gql
• Query.gql

Then I tried calling importSchema in multiple ways, but all of them showed problems. For each of the following pointerOrPointers, these are the results I got:

• ['base.gql', 'User.gql', 'Query.gql'] --> Doesn't include Query.gql.
• ['base.gql', 'Query.gql'] --> Doesn't include Query.gql.
• ['base.gql', 'User.gql'] --> Shouldn't include Query.gql, but does.
• '*.gql' --> Throws an error
• ['User.gql', 'base.gql'] --> Throws an error
• ['Query.gql', 'base.gql'] --> Throws an error
• ['Query.gql', 'User.gql', 'base.gql'] --> Throws an error

I made a reproducible code showing the problem. Edit: a simpler reproducible has been created for this issue.

Could you remove #import from the beginning of the file and try again?

[zvictor]

Removing # import gives me:

• ['base.gql', 'User.gql', 'Query.gql'] --> Renders only base.gql
• ['base.gql', 'Query.gql'] --> Renders only base.gql
• ['base.gql', 'User.gql'] --> Renders only base.gql
• '*.gql' --> Throws an error
• ['User.gql', 'base.gql'] --> Throws an error
• ['Query.gql', 'base.gql'] --> Throws an error
• ['Query.gql', 'User.gql', 'base.gql'] --> Throws an error

I started writing a reproducible to what I thought was a different issue, but it seems after all to actually be the same one. So, here we have another but simpler reproducible of this issue: https://github.com/zvictor/graphql-import-issue-565

Providing multiple sources has some bugs right now. Until we fix it, I recommend you to use single endpoint which is GraphQL Import's main strategy or use https://github.com/ardatan/graphql-toolkit#-file-loading-for-both-schema-and-resolvers for now because it seems you don't need import syntax at all.

Unfortunately things are not that simple on my side. I am using your code inside a framework I am building, so it needs to be quite flexible 😕

As I am building something to work with faunadb's graphql api, I need to always append a file with generic types that already exist inside fauna but are not defined on the user's code.

You can see my implementation at

FYI just manually doing this works for me

const typeDefsResult = loadTypedefsSync('**/*.graphql', {
  loaders: [new GraphQLFileLoader()],
})

const typeDefs = mergeTypeDefs(
  typeDefsResult.flatMap(({ document }) => (document ? [document] : [])),
)

new ApolloServer({ typeDefs, ... })

it might be something to do with the mergeTypeDefs options?

migrating from @graphql-toolkit to @graphql-tools has solved the issue to me, plus a customisation on the graphql-loader.
