Application

This guide explains how to set up a Baeta application and integrate it with a GraphQL server.

Manual Module Registration​

Without autoloading, you need to manually register your modules:

// src/modules/user/index.ts
import "./resolvers";
import { getUserModule } from "./typedef";

export const userModule = getUserModule();

// src/app.ts
import { createApplication } from "@baeta/core";
import { userModule } from "./modules/user";
import { postModule } from "./modules/post";
import { scalarsModule } from "./modules/scalars";

const baeta = createApplication({
  modules: [userModule, postModule, scalarsModule],
});

Automatic Registration (Autoloading)​

Using @baeta/plugin-autoload simplifies the setup:

// baeta.ts
import { defineConfig } from "@baeta/cli";
import { autoloadPlugin } from "@baeta/plugin-autoload";

export default defineConfig({
  plugins: [autoloadPlugin()],
  // ... other config
});

// src/app.ts
import { createApplication } from "@baeta/core";
import { modules } from "./modules/autoload.ts";

const baeta = createApplication({
  // Modules are loaded automatically
  modules,
});

Server Integration​

Apollo Server​

import { ApolloServer } from "@apollo/server";
import { startStandaloneServer } from "@apollo/server/standalone";
import { createApplication } from "@baeta/core";
import { modules } from "./modules/autoload.ts";
import { Context, createContext } from "./context.ts";

const baeta = createApplication({
  modules,
});

const server = new ApolloServer<Context>({
  schema: baeta.schema,
});

const { url } = await startStandaloneServer(server, {
  listen: { port: 4000 },
  context: createContext,
});

console.log(`🚀  Server ready at: ${url}`);

GraphQL Yoga​

import { createServer } from "node:http";
import { createApplication } from "@baeta/core";
import { createYoga } from "graphql-yoga";
import { modules } from "./modules/autoload.ts";
import { Context, ServerContext, createContext } from "./context.ts";

const baeta = createApplication({
  modules,
});

export const yoga = createYoga<ServerContext, Context>({
  schema: baeta.schema,
  context: createContext,
});

const server = createServer(yoga);

server.listen(4000, () => {
  console.log(
    `🚀 Server ready at http://localhost:4000${yoga.graphqlEndpoint}`,
  );
});
