@flatfile/plugin-record-hook
A plugin for running custom logic on individual data records in Flatfile.
@flatfile/plugin-record-hook
The @flatfile/plugin-record-hook plugin offers a convenient way to execute
custom logic on individual data records within Flatfile. By setting up an event
listener for the commit:created event, this plugin seamlessly integrates with
the data processing flow.
Event Type:
listener.on('commit:created')
Parameters
The sheetSlug parameter is the slug of the sheet you want to listen to.
The callback parameter takes a function that will be run on the record or
records.
The chunkSize parameter allows you to specify the quantity of records to in
each chunk.
The parallel parameter allows you to specify the number of chunks to process
in parallel.

Usage
Import
Pass bulkRecordHook or recordHook to a Flatfile data listener and provide a function to run when data is added or updated.
Listen for data changes
Set up a listener to configure Flatfile and respond to data Events. Then use this plugin to set up a hook that responds to data changes.
Additional Options
bulkRecordHook can accept additional properties. Props will be passed along to the transformer.
Flexible Options
Define how many records you want to process in each batch. This allows you to balance efficiency and resource utilization based on your specific use case.
Choose whether the records should be processed in parallel. This enables you to optimize the execution time when dealing with large datasets.
Example Usage
This example sets up a record hook using listener.use to modify records in the “my-sheet” sheet.
When a record is processed by the hook, it checks if an email address is missing, empty, or invalid, and if so, it logs corresponding error messages and adds them to a form validation context (if the r object is related to form validation). This helps ensure that only valid email addresses are accepted in the application.
In the bulkRecordHook example, it passes a chunkSize of 100 and asks the hooks to run 2 at a time via the parallel property.
