in a complex application, you may need to perform additional actions after a database operation. this is where DatabaseTrigger comes in. so you can define a callback to be executed on specific database operations for a collection.

Supported triggers are:

Trigger	Description
find	Triggered when a find query is executed on collection.
find-one	Triggered when a find one query is executed on collection.
count	Triggered when a count query is executed on collection.
update-one	Triggered when a update one query is executed on collection.
insert-one	Triggered when a insert one query is executed on collection.
remove-one	Triggered when a remove one query is executed on collection.
aggregate	Triggered when a aggregate query is executed on collection.

Example

import { DatabaseTrigger } from '@server-ts/database';

const trigger = new DatabaseTrigger('insert-one', ({ query, queryResult }) => {
  console.log('New document inserted:', queryResult);

  try {
    // Perform additional actions after document insertion
  } catch (error) {
    console.error('Error performing additional actions:', error);
  }
});

// Use the trigger in a collection definition
const collection = new CollectionDefinition({
  triggers: [trigger]
});
