Database controllers for client side rendering

This is library for creating client side type-safe database controllers. Integrates out of box with typescript, ORM, Next.JS.

Installation

Install package with npm i csr-controller

Features

$3

To create your first controller use:
``ts
type User = {
name: string,
age: number
} & CRUDBase;

type UpdateUserType = User & CRUDBase;

const UserController = createController({
$url: 'user',
})(crudTemplate)();
`
First, we can skip generics and just call createController(), but for type safety it is recommended way. Every Controller needs three generics:
1. Object type. In our case it's User
2. Create new object type. In our case it's default option - CRUDBase It is made as: { id: string | null }
3. Update object type, simillar to create new object type.

Calling the function, we must specify $url - it's the api path. We can also specify $base. It is default to "custom".

In our case, using UserController any action would fetch relativeServerPath:port/api/custom/user

Next, we must provide template. Here we provide crudTemplate. It is preferred when using web server as it makes direct fetch calls to api and can be shared between projects. In the feature there will be electronTemplate that makes IPC calls.

To add controller behaviour such as making database calls/fetching external api use:
`ts
const routes = controllerRegistry().register(UserController, {
index: async () => {
const users = await db.getUsers(); // Make call to database to fetch all users
return users;
},
read: async data => {
const user = await db.getUser({ id: data.id }); // Make call to database to fetch single user by id
return user;
}
}).handle();
`

#### Usage with popular frameworks

##### Next.JS
To use our routes with Next, create page in api/[base]/[...nextcontroller]. Remember, base defaults to "custom".

`ts
import { withNextRoute } from "csr-controller/apiRoutes/next"
import { controllerRegistry } from "csr-controller/registry"

const routes = controllerRegistry().register(...).handle();

export default withNextRoute(routes, middlewareFoo, middlewareBar);
`

This API page will handle every request from registered controllers.

$3

`ts
// Get all users
const users = await UserController.index();

// Update user
const updatedUser = await UserController.update({ id: 1, / Pass rest data here / })
`

It is recommended to use useSWR` hook when developing with React based frameworks like Next.JS
