Shared Store - Plugins - HTTP - React

@coalesce.dev/store-plugins-http-react

This package provides React hooks and components to use with @coalesce.dev/store-plugins-http.

Usage

Follow usage instructions from @coalesce.dev/store-client-react for information on setting up the required provider.

Hook Generation

Hooks can be generated from a schema that defines HTTP entries using the createHttpPluginHooks function:

import { schema, StoreState } from '../schema';
import { createHttpPluginHooks } from '@coalesce.dev/store-plugins-http-react';

export const { useTodo, useTodoList } = createHttpPluginHooks(schema);

These generated hooks can then be used to fetch values in components.

Request Hooks

Entries that require a request must specify either a value of that request type or undefined to skip fetching any values:

import { useTodoList } from './storeHooks';

function ExampleComponent({ id }: { id: number }) {
  const todo: Todo | undefined = useTodo(id);
  const alsoTodo: Todo | undefined = useTodo(id, false);
  const todoSkipped: Todo | undefined = useTodo(undefined);
  const todoAlsoSkipped: Todo | undefined = useTodo(id, true);

  // ...
}

Requestless Hooks

Entries that do not require a request value can omit the request parameter:

import { useTodoList } from './storeHooks';

function ExampleComponent() {
  const todos: Todo[] | undefined = useTodoList();

  return (
    <ul>
      {todos?.map((t) => (
        <li key={t.id}>{t.title}</li>
      ))}
    </ul>
  );
}

They may also skip fetching values by either passing undefined as the first parameter, or passing null as the first parameter and true as the second:

import { useTodoList } from './storeHooks';

function ExampleComponent() {
  const todos1 = useTodoList(undefined); // will always be undefined
  const todos2 = useTodoList(null, true); // will always be undefined

  // ...
}

Suspense

Hooks are also generated with support for suspense. These hooks work similarly, but have Suspended appended to their names and are typed to return the schema value (not undefined).

import { useTodoListSuspended } from './storeHooks';

function ExampleComponent() {
  const todos = useTodoListSuspended(); // will never be undefined
  // statements following this hook will not be reached until the value is available

  const todoCount = todos.length;

  // ...
}
