CobaltGraphQL without the ``GraphQL``

tRPC's speed, GQL's flexibility. No headaches. No compromise.

🚀

Write Plain TypeScript, Get GraphQL

Define your business logic as simple TypeScript functions. Cobalt automatically generates the GraphQL schema and resolvers.

📝

Get a fully typed SDK powered by Samarium. Enjoy complete autocomplete and type checking for all your API calls.

🔐

Cobalt Auth integrates OpenAuthJS for seamless authentication with multiple providers including OAuth and passwordless.

⚡

Define subscriptions using generator functions. Stream data to clients with GraphQL subscriptions over SSE.

🛠️

Hot reload during development, automatic type generation, and intuitive file-based routing for operations.

📦

Build and deploy with Docker support. Optimized for production with bundled output.

bash

bunx @cobalt27/dev init

Define a query in server/operations/hello.ts:

typescript

export function Query(name: string) {
    return `Hello, ${name}!`;
}

Use it in your frontend:

typescript

import sdk from "sdk";

const greeting = await sdk.query.hello({ name: "Peter" });
// => "Hello, Peter!"

That's it! Cobalt handles the GraphQL schema generation, type inference, and SDK creation automatically.
