write the entry point of the app [ index.ts ]

Write the main function
write the logic in it

const main = async () => {} main();

//This is the start point of the project import { ApolloServer } from "apollo-server-express"; import * as Express from "express"; import { buildSchema, Resolver, Query } from "type-graphql"; import "reflect-metadata";

//make a main function to execute const main = async () => { @Resolver() class HelloResolver { @Query(() => String, { name: "helloWorld" }) hello() { return "hello world"; } } //Our Logic //bootstraping the shcema to add it to http server like apollo-express const schema = await buildSchema({ resolvers: [HelloResolver] });
```
const apolloServer = new ApolloServer({ schema });
const app = Express();
apolloServer.applyMiddleware({ app });
app.listen(4000, () =>
  console.log(`server runs on port http:localhost:4000/graphql`)
);
```
}; main();
