## Features
- No codegen required, everything is inferred using Zod and TypeScript
- All same functions as Prisma supported (not all yet implemented)
- Support for `include`
- Support for `select`
- ~~Pagination~~ (todo)
## 💻 Example usage
```typescript
import { z } from "https://deno.land/x/[email protected]/mod.ts";
import { createPentagon } from "https://deno.land/x/pentagon/mod.ts";
const kv = await Deno.openKv();
export const User = z.object({
id: z.string().uuid().describe("primary"),
createdAt: z.date(),
name: z.string(),
});
export const Order = z.object({
id: z.string().uuid().describe("primary"),
createdAt: z.date(),
name: z.string(),
userId: z.string().uuid(),
});
const db = createPentagon(kv, {
users: {
schema: User,
relations: {
myOrders: ["orders", [Order], "id", "userId"],
},
},
orders: {
schema: Order,
relations: {
user: ["users", User, "userId", "id"],
},
},
});
// Now we have unlocked the magic of Pentagon
const user = await db.users.findFirst({
where: { name: "John Doe" },
select: { name: true, id: true },
});
// We can also do `include` queries, fully typed!
const userWithOrders = await db.users.findFirst({
where: { name: "John Doe" },
include: {
myOrders: true, // 👈 if we want the whole object
/* myOrders: { name: true }, 👈 if we want just some parts to be included */
},
});
```
## Relations
Defining relations works by defining the `relations` key in the table
definition. This allows us to `include` the values of relations, the same way as
we are familiar with from Prisma.
The type signature
[RelationDefinition](https://github.com/skoshx/pentagon/blob/fae437d373df89a1610a998e940c92213d3134b3/src/types.ts#LL56C24-L56C24)
explains what each of the array values represent.
Basically, we have `[relation name, schema, local key, foreign key]`.
For instance, a many-to-one relation could look like this:
```typescript
users: {
schema: User,
relations: {
myOrders: ["orders", [Order], undefined, "userId"],
},
},
orders: {
schema: Order,
relations: {
user: ["users", User, "userId", "id"],
},
},
```
## 💻 Development
