Aerographql NPM

AeroGraphQL is a small and opinionated Typescript toolkit to create GraphQL server using a declarative approach.

Overview

Install AeroGraphQL

yarn add aerographql

Note that graphql is a needed peer dependency, you must install it beforehand

Define your schema

@ObjectDefinition( { name: 'User' } )
export class User {
    @Field( { type: 'ID' } ) id: string;
    @Field( ) name: String;
    @Field( { nullable: true }) description: String;
}

@ObjectImplementation( { name: 'RootQuery' } )
export class RootQuery {
    constructor( private userService: UserService ) { }

    @Resolver( { type: User } )
    user( @Arg() name: string ): User | Promise<User> {
        return this.userService.find( name );
    }
}

@Schema( {
    rootQuery: 'RootQuery',
    components: [ RootQuery, User ]
} )
export class MySchema extends BaseSchema {
}

Inject the schema within a GraphQL server

Apollo Server with Express in this case:

let mySchema = new MySchema();
this.app = express();
this.app.use( '/graphql', bodyParser.json(), graphqlExpress( { schema: mySchema.graphQLSchema } );
this.app.listen( config.get( 'server.port' ), () => {
    console.log( 'Up and running !' );
} );
