Parse Server Import Objects Example

This is a live example for this Gist that shows how to import data to a Parse Server database.

In order to run this example, first create a data.json file like this:

{
	"className": "ExampleClass",
	"rows": [
		{ "ExampleColumnA": "row1columnA", "ExampleColumnB": "row1columnB" },
		{ "ExampleColumnA": "row2columnA", "ExampleColumnB": "row2columnB"}
	]
}

Then you just need to run a curl command like this:

curl -X POST \
-H "X-Parse-Application-Id: LL9oIdzIkmwl5xyowQQu0fTmXyUWfet9RuAzwHfj" \
-H "X-Parse-REST-API-Key: R3S8PYQKuzeV4c8MUeO5ved46C50MEp56boDHW1O" \
-H "Content-Type: application/json" \
-d @data.json \

You can see the imported rows by checking the ExampleClass.

Use the clone button on the top of this page to clone this example to your account and see how it works. Basically it is running Parse Server 3.9.0 and it was added a main.js file with the following cloud code function:

Parse.Cloud.define('import', async request => {
  const className = request.params.className;
  const rows = request.params.rows;

  const MyClass = Parse.Object.extend(className);

  var myClassObjects = [];
  for (let i = 0; i < rows.length; i++) {
    const myClassObject = new MyClass();

    for (const column in rows[i]) {
      myClassObject.set(column, rows[i][column]);
    }

    myClassObjects.push(myClassObject);
  }

  try {
    await Parse.Object.saveAll(myClassObjects);
  } catch (e) {
    throw new Error(`Import failed: ${e}`);
  }
  
  return `Successfully imported ${myClassObjects.length} rows into ${className} class`;
});
