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.
Summary of key details for the configuration type
| File name or type | Contains secrets | Path extracted/imported to | Maximum allowed per integration runtime |
|---|---|---|---|
| ZIP | Yes | /home/aceuser/ace-server/config/connectors/loopback/ | Multiple |
About the LoopBack data source file
Create a configuration of type LoopBack data source to enable an integration runtime to manipulate data that is stored in a MongoDB or PostgreSQL database. You
must configure the data source for the LoopBack connector
by creating or updating a datasources.json file and specify security
credentials if you are connecting to a secured data source. You must also provide a model definition
file for the data model for the integration runtime to 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 are extracted into the
/connectors/loopback directory in the 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.
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 runtime, or independently, as follows:
- Open the Configuration page by clicking the
Configuration icon
in the navigation pane. Then, click
Create configuration. For more information, see Creating configurations on the Configurations page. - From the
Create configuration
panel, select LoopBack data source from the Type list. - In the Name field, specify a name for this configuration.
- In the Description field, specify text that will help you identify the
integration runtime that will use the files in the ZIP archive,
or identify the content of the archive.
- 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.
- Click Create. The configuration is added to the configurations table and can be selected for use with an 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 needed, see Creating configurations on the Configurations page.
