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

In the previous chapter, the Supabase table was manually defined within the cloud dashboard to verify the reading and integration with Supabase. However, for the subsequent steps of the application, the most appropriate method to carry out this kind of procedure will be used. In everyday development, a local environment is needed that allows the writing and testing of code by simulating the production or staging environment as closely as possible. In the short term, manually modifying and creating the various data tables is not a good practice because it is prone to errors. If a column needs to be added to the table, it is unthinkable to delegate the activity to a person. With a thousand steps and tasks to perform, the risk of error is too high, and the changes made to the database would not be versioned. Let's imagine a new feature needs to be added to the user profile, such as showing the profile photo within the personal area. The front end will need all the data to display the image and ensure that it is correctly visible in all resolutions. This work is purely related to the Qwik code, but the image information from the database is needed. Therefore, along with this functionality, this new field on the Supabase table is also needed. Ideally, the database should be modified only when the functionality is available. So, remember to update the database only when the functionality is ready and released. If it's an addition of a column, it's a trivial activity. But what if the user table data needs to be changed to split the user name into two separate fields, first name, and last name? If the code expects a single field and the data is modified, the application will have problems because it will be inconsistent. Here, using an automated and versioned migration system saves a lot of problems and makes it easier to release features.

Managing the entire process with Supabase is very simple because the tool's CLI is available, which allows all operations to be performed very quickly and securely.

You can find the full code for this module in the following Replit:

To use the Supabase CLI, install the dependency within the project with the following command:

// Supabase CLI as dev dependency via pnpm:
pnpm install -D supabase

Inside the package.json, a dedicated script for Supabase can be created so it can be used like this: 

  "scripts": {
    [...]
    "supabase": "supabase"
  },

So far, so good. Now, first of all, execute the following command to initialize the Supabase database locally.
