realm javascript (ok)

https://realm.io/docs/javascript/latest/

Ví dụ:

import realm from './../realm';
export const getListTasks = () => {
  const tasks = realm.objects('Task')
  return Promise.resolve(tasks)
}
export const addTask = (name) => {
  if (!name) {
    return Promise.reject('Task name is empty')
  }
  const data = {
    created: new Date(),
    name,
    completed: false
  }
  const tasks = realm.objects('Task')
  return new Promise((resolve, reject) => {
    realm.write(() => {
      realm.create('Task', data)
      resolve(tasks)
    })
  })
}
export const removeTask = (task) => {
  const tasks = realm.objects('Task')
  return new Promise(resolve => {
    realm.write(() => {
      realm.delete(task)
      resolve(tasks)
    })
  })
}
export const toggleTask = (task) => {
  const tasks = realm.objects('Task')
  return new Promise(resolve => {
    realm.write(() => {
      task.completed = !task.completed
      resolve(tasks)
    })
  })
}

Chú ý:

1. Bước 1 lấy dữ liệu trên database
const tasks = realm.objects('Task');
2. Bước 2: Thực hiện theo mẫu ghi, xóa, chỉnh sửa
return new Promise(resolve => {
    realm.write(() => {
        // code
        resolve(variable)
    })
});
