TypeGraphQL series

This repo is my practice typescript and graphql along with other stuffs.

What we will cover?

• setup type-graphql: how we can setup a type-graphql server

• register resolver: how we can create register and validate user input, throw errors back to user.

• login resolver: how we can know whether user login

• authorization/middleware: protect a row/query for just login user

• confirm email: sending an email to user to confirm account.

• forgot/change password: reset password in database (I use PostgreSQL)

• higher order resolvers: writing programmatically typegraphql resolvers as functions basically (for resuse)

Setup type-graphql server

This project I use yarn as a package management. You can use npm if you like. Then I install a few things for Apollo Server Express.

yarn add apollo-server-express express graphql reflect-metadata type-graphql

We need reflec-metadata since it is a library that we need for type-graphql. We also need the type versions (as we use Typescript) for those libraries

yarn add -D @types/express @types/graphql @types/node typescript nodemon ts-node

Here are what we need, if you have any trouble, please check the official site of type-graphql first: Installation

Then, we need create a tsconfig.json file for typescript know how to compile our code. I use this config: tsconfig.json (Ben Awad) and change a little bit, you can check the tsconfig.json in my github for this project as well.

import { ApolloServer } from "apollo-server-express";
import * as Express from "express";
import { buildSchema, Resolver, Query } from "type-graphql";

@Resolver()
class HelloResolver {
  @Query(() => String)
  async hello() {
    return "hello, world";
  }
}

const main = async () => {
  const schema = await buildSchema({
    resolvers: [HelloResolver]
  });
  const apolloServer = new ApolloServer({ schema });

  const app = Express();

  apolloServer.applyMiddleware({ app });

  app.listen(4000, () =>
    console.log("server started on http://localhost:4000")
  );
};

main();
