# Sveltekit - Taro Stack 

## ❗ Important

If you forked this repository before May 27th, you'll want to view commit `653e2c2`. There was an issue with the Hono context
not correctly parsing routes.

## ❔ What

A scalable, testable, extensible, boilerplate for Sveltekit.

Sveltekit is awesome. File-based routing, SSG/SSR, and having the ability to have a backend attatched to your frontend saves incredible amounts of time and effort.

But the default backend sometimes isn't enough. There are some projects that require more powerful and feature rich backends. I'm talking Middleware, guards, pipes, interceptors, testing, event-emitters, task scheduling, route versioning, and so on.

So what I've done is attatched Hono, a fully fletched backend, to run on the Sveltekit process and forward all API requests to it.

`/api/[...slugs]`

```ts
import app from '$lib/api';
import type { RequestHandler } from '@sveltejs/kit';

export const GET: RequestHandler = ({ request }) => app.fetch(request);
export const PUT: RequestHandler = ({ request }) => app.fetch(request);
export const DELETE: RequestHandler = ({ request }) => app.fetch(request);
export const POST: RequestHandler = ({ request }) => app.fetch(request);
```

  - 🟢 Email Update/Verifiaction


## Technologies

- [Lucia](https://lucia-auth.com): Hits the right level of abstraction for me. Hand me the tools to build a secure authentication system and let me implement it to suite my needs
- [Drizzle](https://orm.drizzle.team/) - Drizzle advertises itself as an ORM but I think its deceptive. Its a query builder with a migration client. Everytime I've used an ORM, I find myself fighting it for sometimes the simplist of use cases. Drizzle just gives you type-safety while querying SQL in a native fashion. Learn SQL, not ORMs.
- [Hono](https://hono.dev/): Fast, lightweight, and built on web standards; meaning it can run anywhere you're Sveltekit app can. It's essentially a better, newer, and ironically more stable Express.JS. This provides us an extreemely good foundation to cleanly build ontop of without having to teardown first. It has a zod adapter for validating DTO's which can be shared with the frontend too.
- [Sveltekit](https://kit.svelte.dev/): After trying Vue, React, Next, and pretty much every frotnend framework in the JS ecosystem, its safe to say I vastly prefer Svelte and its priority of building on web standards.

## Architecture

There are a few popular architectures for structuring backends. Technical, Onion, VSA, and the list goes on. I almost always choose
to start with Technical and let the project naturally evolve into one of the others. 

### Folder Structure
* **controllers** - Responsible for routing requests

* **services** - Responsible for handling business logic.

* **repositories** - Responsible for retrieving and 
storing data.

* **infrastructure** - Handles the implementation of external services or backend operations.

* **interfaces** - Common

* **middleware**  - Middlware our request router is responsible for handling.

* **providers** - Injectable services

* **dtos** - Data Transfer Objects (DTOs) are used to define the shape of data that is passed.

* **common** - Anything commonly shared throughout the backend


### File Naming
You might notice how each file in the backend is postfixed with its architectural type(e.g. `iam.service.ts`). This allows
us to easily reorganize the folder structure to suite a different architecture.

For example, if you want to group folders by domain(DDD), you simply drag and drop all related files to that folder.
```
└── events/
    ├── events.controller.ts
    ├── events.service.ts
    └── events.repository.ts
```


## Testing

Testing probably isn't first and foremost when creating an app. Thats fine. You shouldnt't be spending time writing tests if your app is changing and pivoting.

BUT a good stack should be **testable** when the time to solidify a codebase arrives. I created this stack with that pinciple in mind. I've provided a examples of how to write these tests under `authentication.service.test.ts` or `users.service.test.ts`
