<|file_sep|># Apollo Federation
The [Apollo Federation](https://www.apollographql.com/docs/apollo-server/federation/introduction/) specification allows multiple GraphQL services (or subgraphs)
to be combined together into a single data graph.
The [federation example](./examples/federation/) uses gqlgen v0.11.x features such as [GraphQL directives](https://github.com/99designs/gqlgen/blob/master/docs/directives.md)
and [custom scalars](https://github.com/99designs/gqlgen/blob/master/docs/scalars.md) along with federation-specific directives.
## Example
### Creating Subgraph Service
Create subgraph service which exposes `User` entity.
bash
mkdir -p examples/federation/user/cmd && cd examples/federation/user
go mod init github.com/99designs/gqlgen/examples/federation/user
go get github.com/99designs/[email protected]
Create `graph/schema.graphql` file:
graphql
directive @key(fields: String!) repeatable on OBJECT | INTERFACE
directive @external on FIELD_DEFINITION
directive @requires(fields: String!) repeatable on FIELD_DEFINITION
directive @provides(fields: String!) repeatable on FIELD_DEFINITION
scalar DateTime
# User type represents user entity in our system.
# It implements `User` interface which can be used by other subgraphs.
# It also defines key field which is used by Apollo Federation for distributed data storage.
type User @key(fields: "id") {
id: ID!
name: String!
email: String!
bio: String
twitter: String @external
lastUpdated: DateTime @external
}
Create `graph/schema.resolvers.go` file:
go
package graph
import (
"context"
)
// This file will be automatically regenerated based on the schema,
// any resolver implementations will be copied through when generating and any unknown code will be moved to the end.
type Resolver struct{}
func (r *mutationResolver) CreateUser(ctx context.Context, input NewUser) (*UserResolver, error) {
panic("not implemented")
}
func (r *queryResolver) User(ctx context.Context, id string) (*UserResolver, error) {
panic("not implemented")
}
// Mutation returns MutationResolver implementation.
func (r *Resolver) Mutation() MutationResolver { return &mutationResolver{r} }
// Query returns QueryResolver implementation.
func (r *Resolver) Query() QueryResolver { return &queryResolver{r} }
type mutationResolver struct{ *Resolver }
type queryResolver struct{ *Resolver }
Create `cmd/server/main.go` file:
go
package main
import (
"context"
"fmt"
"log"
"net/http"
"github.com/99designs/gqlgen/graphql/handler"
"github.com/99designs/gqlgen/graphql/playground"
graph "github.com/99designs/gqlgen/examples/federation/user/graph" // import generated resolvers package
"github.com/99designs/gqlgen/examples/federation/user/graph/generated"
)
func main() {
port := "8081"
srv := handler.NewDefaultServer(generated.NewExecutableSchema(generated.Config{Resolvers: &graph.Resolver{}}))
http.Handle("/", playground.Handler("Subgraph playground", "/query"))
http.Handle("/query", srv)
log.Printf("connect to http://localhost:%s/ for subgraph playground", port)
log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s", port), nil))
}
Create `go.mod` file:
go
module github.com/99designs/gqlgen/examples/federation/user
go 1.14
require (
github.com/99designs/gqlgen v0.11.x // replace x with latest minor version number
github.com/google/uuid v1.1.1 // used for generating random IDs for users created by mutations resolver function
)
Run subgraph service:
bash
go run cmd/server/main.go # starts server listening on port :8081
### Creating Gateway Service
Create gateway service which combines multiple subgraphs together.
bash
mkdir -p examples/federation/gateway && cd examples/federation/gateway
go mod init github.com/99designs/gqlgen/examples/federation/gateway
go get github.com/99designs/[email protected] github.com/vektah/gqlparser/[email protected] # gqlparser v0.x.x required until gqlgen supports v1.x.x parser versions
Create `gateway.graphql` file:
graphql
directive @key(fields: String!) repeatable on OBJECT | INTERFACE
directive @external on FIELD_DEFINITION
directive @requires(fields: String!) repeatable on FIELD_DEFINITION
directive @provides(fields: String!) repeatable on FIELD_DEFINITION
scalar DateTime
# Query root type which exposes `users` query field.
type Query {
users(ids: [ID!]!): [User!]!
}
Create `gateway/schema.resolvers.go` file:
go
package gateway
import (
context "context"
)
// This file will be automatically regenerated based on the schema,
// any resolver implementations will be copied through when generating and any unknown code will be moved to the end.
type Resolver struct{}
func (r *queryResolver) Users(ctx context.Context, ids []string) ([]*UserResolver, error) {
panic("not implemented")
}
// Query returns QueryResolver implementation.
func (r *Resolver) Query() QueryResolver { return &queryResolver{r} }
type queryResolver struct{ *Resolver }
Create `cmd/server/main.go` file:
go
package main
import (
context "context"
fmt "fmt"
log "log"
netHttp "net/http"
federation "github.com/99design.com/go-federation/v2" // go-federation package provides necessary types such as `GatewayConfig` used by gqlgen generated code
gateway "github.com/99designs/gqlgen/examples/federation/gateway" // import generated resolvers package
generated "github.com/99designs/gqlgen/examples/federation/gateway/generated" // import generated code package
handler "github.com/99designs/gqlgen/graphql/handler" // gqlhandler provides request handlers which are used by gateway service
playground "github.com/99designs/gqlgen/graphql/playground" // playground handler used by gateway service
)
const port = "8080"
func main() {
cfg := federation.GatewayConfig{
// add subgraph services which should be merged into single data graph exposed by gateway service
Subgraphs: map[string]federation.Service{
"user": federation.Service{
URL: fmt.Sprintf("http://localhost:%s/query", port + "1"),
FetchFunc: func(ctx context.Context,
