LoopBack data source type

Use the LoopBack data source type to create configurations that use LoopBack connectors to issue synchronous requests to create, retrieve, update, and delete data in a backend data source. Only the LoopBack connectors for MongoDB and PostgreSQL are supported.

About the LoopBack data source file

Create a configuration of type LoopBack data source to enable an integration server or integration runtime to manipulate data that is stored in a MongoDB or PostgreSQL database. You will need to configure the data source for the LoopBack connector by creating or updating a datasources.json file and specify security credentials if connecting to a secured data source. Also provide a model definition file for the data model that the integration server or integration runtime will interact with.

The LoopBack data source type requires a ZIP file that contains the entire contents of a LoopBack data source (datasources.json and data source model files), including the folder that has the LoopBack data source name. The ZIP file contents will be extracted into the /connectors/loopback directory in the integration server or integration runtime work path.

The maximum recommended size of a ZIP file for a configuration is approximately 660 KB.

For more information, see Configuring the data source and models for your LoopBack connector and Using models with LoopBack connectors.

For examples of how to use this configuration type, see Tutorials and examples.

Creating a configuration for the LoopBack data source type by using the configuration panel

You can create a LoopBack data source-type configuration while creating an integration server or integration runtime, or independently, as follows:

  1. From the Configuration page (accessed by clicking the Configuration icon Configuration icon), or the Configuration view of an integration server or integration runtime that you are creating, click Create configuration. For more information about this page or view, see Managing configuration objects from the Configuration page.
  2. From the Create configuration panel, select LoopBack data source from the Type list.
  3. In the Name field, specify a name for this configuration.
  4. In the Description field, specify text that will help you identify the integration server or integration runtime that will use the files in the ZIP archive, or identify the content of the archive.
    Create configuration panel
  5. To import the LoopBack data source, click within the boxed area to select the ZIP file from a file browser, or drag-and-drop: the file. The name of the imported file is displayed.
    Imported ZIP file
  6. Click Create. The configuration is added to the configurations table and can be selected for use with an integration server or integration runtime.

Updating or deleting a configuration

If you need to update the content or settings in a configuration, or delete a configuration that's no longer required, see Managing configuration objects from the Configuration page.
