Move Data JSON Method

Moves data from a file to another

Syntax

async function moveData() {
  try {
    const from = "source-data";     // Name of the source data
    const to = "destination-data";  // Name of the destination data
 
    const options = {
      query: { searchText: "example" },  // Optional query to filter data
      dropSource: true                    // Optional flag to drop source data after moving
    };
 
    // Move data from the source to the destination with optional parameters
    const results = await dataAdapter.moveData(from, to, options);
 
    console.log(results);
  } catch (error) {
    console.error(error);
  }
}
 
moveData();

Explanation:

1. from:

   • Specifies the name of the source data from which the data will be moved.

2. to:

   • Specifies the name of the destination data where the data will be moved.

3. options:

   • An optional object containing additional parameters:
     • query: Optional query to filter the data before moving.
     • dropSource: Optional boolean flag indicating whether to drop the source data after moving.

4. Filtering Source Data:

   • If the query option is provided, the function loads all data from the source data matching the specified query using the loadAll method.
   • If the filtered data is not empty, it replaces the source data with the filtered data.

5. Dropping Source Data:

   • If the dropSource option is true, the function removes the source data after moving it to the destination.
   • If a query is provided, it removes only the filtered data from the source.
   • If no query is provided, it removes all data from the source.

6. Moving Data to Destination:

   • The function loads data from the destination using the load method.
   • It appends the source data to the existing data in the destination.
   • It then writes the combined data to the destination file.

7. Encoding Data (if secure):

   • If data encryption is enabled, the function encodes the data before writing it to the file.

8. Logging:

   • Success or error logs are maintained throughout the function execution for debugging and monitoring purposes.

9. Result:

   • The function returns an object containing acknowledgment of the operation's success, a message indicating the outcome, and the moved data in the destination.
