Features

The SAP Fiori - UI5 middleware for the Fiori elements mock server is a middleware extension for the UI5 Tooling. As an alternative to proxying OData requests to a live backend, it supports loading mock data for OData v2/v4 requests for supported Fiori elements templates. As the mock server runs locally without requiring a network connection to a backend system, it is useful for development and test scenarios.

yarn yarn add @sap-ux/ui5-middleware-fe-mockserver --dev

              metadataPath: './webapp/localService/other_metadata.xml'
              mockdataPath: './webapp/localService/data'

Service Configuration

Each service must provide at least two things

• urlPath : where will your service be accessible from
• metadataPath : local path to your metadata file

On top of that you can specify one of the following option

• mockdataPath : the path to the folder containing the mockdata files
• generateMockData : whether or not you want to use automatically generated mockdata

Additional option are available either per service of for all services if defined globally

• debug : toggle the debug mode
• watch : toggle the watch mode, the mockserver will restart the service where data or metadata have changed
• noETag : disable ETag support on metadata
• strictKeyMode : disable the default "loose" mode for the key matching, you can try this if the mockserver returns too much data
• contextBasedIsolation : enable the support of "tenants", by adding /tenant-xxx at the very start of your service call you will be able to work on tenant isolated data.
