useContent()

We can effectively handle data management through the utilization of useContent().

To streamline data management within your application, you can utilize the powerful capabilities offered by useContent, a feature provided by the @magicjs.dev/frontend library.

Here's a concise example of how to integrate useContent into your application:

import { createComponent, Frontend } from '@magicjs.dev/frontend';

export default createComponent((props) => {
  // Destructure the useContent function from the provided props
  const { useContent } = props.use(Frontend);

  // Initialize contentEditor using useContent
  const contentEditor = useContent({
    serviceId: "uniqueIdentifier", // Ensure serviceId is unique
    defaultContent: {/* Add your default content here */},
    useReduxStore: false, // Control whether to utilize Redux store for data management
  });
})

Here are some key points to consider:

  • Unique Service ID: It's crucial to assign a unique serviceId to each instance of useContent. This identifier distinguishes between different data services and ensures proper management and isolation of data.

  • Default Content: If you wish to provide default content upon initialization, you can do so by setting the defaultContent parameter. This allows for seamless rendering of content without the need for additional checks or handling.

  • Redux Store Integration: By toggling the useReduxStore parameter, you can control whether changes to data propagate across components. Setting it to true enables synchronization of data changes, facilitating consistent state management throughout your application.

Operations

setContent

Type: Function

The setContent() function is used to update the content with new information. It accepts an object with various properties as its argument. For example, it could be used to update the contents of a text editor or content management system.

Example:

<button
  onClick={contentEditor.setContent({
    title: 'Sample',
    keyA: 1,
    keyB: 2,
    items: [1, 2, 3],
    emptyArrayToPush: [],
    itemsToRemoveFrom: ['a', 'b', 'c', 'd', 'e'],
    innerObj: {
      collection: [
        {
          subTitle: 'Collection Sub Title',
        },
      ],
    },
  })}
>
  Set Content
</button>

You can use console.log(contentEditor.content) to see the data contained by the content property of contentEditor.

updateKey

Type: Function

The updateKey() function is used to update a property in an object. It accepts two arguments:

NameTypeDescriptionRequiredDefault

key

string

The name of the property to update.

Yes

value

any

The new value to assign to the property.

Yes

Example:

<button
  onClick={() => {
    updateKey('title', 'Sample Updated Title');
  }}
>
  Update Title
</button>

pushItem

Type: Function

The pushItem() function is used to push data to an array. It accepts two arguments:

NameTypeDescriptionRequiredDefault

key

string

The name of the array to push to.

Yes

value

any

The value to push to the array.

Yes

Example:

Push a value to an array:

<button 
  onClick={() => {
      pushItem('items', 4);
  }}
>
  Push to Items Array
</button>

In the code above, pushItem is a function that takes two arguments: the name of the array and the value you want to push to that array. In this case, we are pushing the number 4 to the items array. When the button is clicked, the onClick event executes the pushItem function, which updates the items array by adding 4 to the end of it.

removeItemAt

Type: Function

The removeItemAt() function is used to remove an item from an array at a specific index. It accepts two arguments:

NameTypeDescriptionRequiredDefault

key

string

The name of the array to remove the item from.

Yes

value

number

The index of the item to remove from the array.

Yes

Example:

Remove an item at a specific index:

<button
  onClick={() => {
    contentEditor.removeItemAt('itemsToRemoveFrom', 5);
  }}
>
  Remove item at index 5
</button>

In the code above, you can replace itemsToRemoveFrom with the variable that you want to remove an item from, and 5 with the index of the item that you want to remove.

runBatch

Type: Function

The runBatch() function is used to perform multiple operations (remove, update, and push) in a single operation. It accepts an object with various properties as its argument.

Example:

Button that updates multiple keys at once

<button onClick={() => {
  runBatch(() => {
    updateKey('keyA', 100);
    updateKey('keyB', 200);
  });
}}>
  Update multiple key
</button>

Here, two functions named runBatch and updateKey to update the values of two keys ('keyA' and 'keyB') in the object.

Button that push multiple items to an array at once

 <button
  onClick={() => {
    runBatch(() => {
      pushItem('emptyArrayToPush', 100);
      pushItem('emptyArrayToPush', 200);
    });
  }}
>
  Push multiple items
</button>

Here, two functions named runBatch and pushItem to push two items (100 and 200) to an array named emptyArrayToPush.

Remove Items at specific indices from an array at once

<button
  onClick={() => {
    runBatch(() => {
      removeItemAt('itemsToRemoveFrom', 3);
      removeItemAt('itemsToRemoveFrom', 5);
    });
  }}
>
  Remove items at indices 3 and 5
</button>

Here, two functions named runBatch and removeItemAt to remove items from an array named itemsToRemoveFrom. In this case, items at index 3 and index 5 will be removed.

  • The runBatch function accepts a function as an argument and runs it as a batch operation, which can help improve performance when updating multiple operations at once.

It is not recommended to use asynchronous code inside runBatch function as it may cause unexpected behavior.

The hasChanged is a boolean that indicates whether any changes have been made to the content.

markAsSaved
