8.2 Before and after hooks to datasource calls

8.2.1 Adding before and after hooks

You can execute custom workflows before_method_hook and after_method_hook any datasource call. this applies to all kinds of datasources you integrate in a godspeed project, whether of type api,redis, kafka etc

• before_method_hook this hook will trigger a workflow before executing the any method of the datasource in a task.

src/datasource/test_datasource.yaml

type: api
schema:
base_url: <% config.httpbin.base_url %>    
before_method_hook: com.jfs.audit_log_workflow

• after_method_hook this hook will trigger a workflow after executing the method of the datasource in a task.

src/datasource/test_datasource.yaml

type: api
schema:
base_url: <% config.httpbin.base_url %>    
after_method_hook: com.jfs.audit_log_workflow

• To access datasource context in the workflows of the before_method_hook and after_method_hook use <% config.context %> script.

for eg.

summary: 'hook workflow for testing'
id: logging_input_output
tasks: 
 - id: audit_log
   fn: com.gs.transform
   args:
     request: <% config.context %>
     response: <% outputs %>

context of datasource type: api

{
  "type": "api",
  "base_url": "https://dummyjson.com",
  "gsName": "testdatasource",
  "url": "/products/1",
  "method": "post",
  "body": {
    "test": "key"
  }
}```
