How to build a GraphQL API Gateway with Nodejs
Suppose I have N numbers of Microservice which are serving GraphQL API and I want to build a API Gateway for them with GraphQL.
So the communication would go like this :
Client sends a request in the form of JSON like
{
User{
name
}
Article(id: "sa"){
title
}
}
API Gateway takes this input and forwards it to different microservices such as the User related query will go to User Microservice and Article related query will go to Article Microservice.
User{
name
}
// Call to User Microservice
Article{
title
}
// Call to Article Microservice
I am not sure how to implement this with GraphQL and Nodejs.

You should only use one GraphQL server which acts as the gateway that called to individual services apollographql.com/docs/images/graph-layer.png

But how it would serve the purpose of Microservice? We have to define the whole schema thing in API Gateway for each Microservices and also adding only one property in any Microservice would push us to change the schema at API Gateway also.

You can use schema stitching to combine multiple graphql servers.

Use this with schema delegation: https://www.apollographql.com/docs/graphql-tools/schema-delegation.html
