React hooks to use IndexedDB.

Quick start

Wrap your application with IndexedDBProvider and provide your configuration to it:

import { useIndexedDB, IndexedDBConfig } from '@unrulyeon/react-indexeddb'

export const indexedDBConfig: IndexedDBConfig = {
  name: 'todos-app',
  version: 1,
  objectStores: [
    {
      name: 'todos',
      options: {
        keyPath: 'id',
        autoIncrement: true,
      },
      indices: [
        { name: 'title', keyPath: 'title', options: { unique: false } },
      ],
    },
  ],
}

const App = () => {
  return (
    <IndexedDBProvider config={indexedDBConfig}>
      <TheRestOfYourApplication />
    </IndexedDBProvider>
  )
}

Now you can use the useIndexedDB hook to retrieve and useMutateIndexedDB to mutate data:

import { useIndexedDB, useMutateIndexedDB } from '@unrulyeon/react-indexeddb'

type Todo = {
  id: number
  title: string
}

type NewTodo = Omit<Todo, 'id'>

const Todos = () => {
  const { data: todos } = useIndexedDB<Todo>({
    name: 'todos',
    key: ['todos'],
    fn: ({ getAll }) => getAll(),
  })

  const {
    put: updateTodo,
    remove: remoteTodo,
    invalidate,
  } = useMutateIndexedDB<NewTodo, Todo>({
    name: 'todos',
  })

  const addTodo = async (todo: NewTodo) => {
    await updateTodo(todo)
    invalidate(['todos'])
  }

  const deleteTodo = async (id: number) => {
    await remoteTodo(id)
    invalidate(['todos'])
  }

  return (
    <div>
      {todos?.map((todo) => (
        <div key={todo.id}>
          <span>{todo.title}</span>
          <button onClick={() => deleteTodo(todo.id)}>Delete</button>
        </div>
      ))}
      <button onClick={() => addTodo({ title: 'New todo' })}>Add</button>
    </div>
  )
}
