We created a free course to create your first GraphQL server (from scratch) using Node and TypeScript. TypeScript and GraphQL are a powerful combo, but there's a lot of confusing edges if you're getting it setup the first time.

In this course we cover the basics of getting TypeScript setup with Node, how GraphQL works, and how to set up a GraphQL server using Apollo server. It's two hours long, it comes with complete code examples, and we walk through the code step-by-step.

It's taught by my friend, Shopify-engineer Hassan Djirdeh and he's integrated what he's learned using GraphQL in production as an engineer at Shopify. We've already had over 1,300 students enroll and it's been getting great reviews so far.

Complete Guide to Qwik

To actively follow this chapter and create the application, ensure that both 

 are installed on your local computer. Alternatives such as 

 might be a preferred choice due to its efficiency and several advantages. In fact, with 

, when a package is installed, it is stored in a global folder on your computer. Therefore, for each version of a module, there is always only one copy stored on the disk because it creates symbolic links and does not re-download the packages. When using 

, for example, if there are 10 projects that use "package A", there will be 10 copies of "package A" on the disk. So, 

 saves a lot of disk space and installation time, let's use it.

# Technical Requirements

To actively follow this chapter and create the application, ensure that both [Node.js](https://nodejs.org/en) and `npm` are installed on your local computer. Alternatives such as `yarn` and `pnpm` can also be used. `pnpm` might be a preferred choice due to its efficiency and several advantages. In fact, with `pnpm`, when a package is installed, it is stored in a global folder on your computer. Therefore, for each version of a module, there is always only one copy stored on the disk because it creates symbolic links and does not re-download the packages. When using `npm` or `yarn`, for example, if there are 10 projects that use "package A", there will be 10 copies of "package A" on the disk. So, `pnpm` saves a lot of disk space and installation time, let's use it.

## Supabase for Your Backend

After some evaluations, it's clear that the most interesting database to use for your application is Supabase. Below are the advantages:

-   **Highly integrated with Qwik**: In fact, it is included in the official integrations of the framework, so compatibility is guaranteed by the team that oversees the project, as well as by the maintainers and the large community present.
-   **Supabase configuration**: It's very simple and fast. In fact, in just a few minutes, you can obtain a working solution. All this is thanks to the UI interface that facilitates operations.
-   **Authentication and authorization**: These operations are highly integrated with the ability to securely manage user accounts, roles, and permissions, ensuring safety and security for your data.
-   **Postgres support**: This allows you to manage complex data relationships and queries effortlessly. This is a significant advantage over other platforms that often offer limited database capabilities.
-   **Supabase SDK**: Managing the connection and all database operations is very simple thanks to the provided SDK.
-   **Real-time status**: This supports listening to Postgres database changes, monitoring, and synchronizing shared state between clients or sending temporary messages from client to client with low latency. These features are not obvious for this kind of service, and knowing that you can use them effortlessly is very nice.
-   **Environments**: It is possible to have multiple environments for your use. You can have the production environment, the test environment, and you can create all the environments you need.
-   **Migrations**: Having multiple environments and evolving your database feature after feature, it is possible to automatically migrate the database schema. This guarantees consistency and saves you the burden of managing everything manually, avoiding human errors.
