Script execution sequence

All onRequest and onResponse scripts are executed in sequence. First, the onRequest scripts are executed from the top down, then the onResponse scripts are executed from the bottom up.

client -> filter 1 onRequest -> filter 2 onRequest -> resource
client <- filter 1 onResponse <- filter 2 onResponse <- resource

The following sample router configuration shows the order in which the scripts would be executed:

{
    "filters" : [
        {
            "onRequest" : {
                "type" : "text/javascript",
                "source" : "require('router-authz').testAccess()"
            }
        },
        {
            "pattern" : "^managed/user",
            "methods" : [
                "read"
            ],
            "onRequest" : {
                "type" : "text/javascript",
                "source" : "console.log('requestFilter 1');"
            }
        },
        {
            "pattern" : "^managed/user",
            "methods" : [
                "read"
            ],
            "onResponse" : {
                "type" : "text/javascript",
                "source" : "console.log('responseFilter 1');"
            }
        },
        {
            "pattern" : "^managed/user",
            "methods" : [
                "read"
            ],
            "onRequest" : {
                "type" : "text/javascript",
                "source" : "console.log('requestFilter 2');"
            }
        },
        {
            "pattern" : "^managed/user",
            "methods" : [
                "read"
            ],
            "onResponse" : {
                "type" : "text/javascript",
                "source" : "console.log('responseFilter 2');"
            }
        }
    ]
}

This configuration would produce a log as follows:

requestFilter 1
requestFilter 2
responseFilter 2
responseFilter 1

Example Filter Configuration

This example executes a script after a managed user object is created or updated:

{
    "filters": [
        {
            "pattern": "^managed/user",
            "methods": [
                "create",
                "update"
            ],
            "onResponse": {
                "type": "text/javascript",
                "file": "scripts/afterUpdateUser.js"
            }
        }
    ]
}
