SDAPI Breakpoints 2.0

A breakpoint represents a location in a script file. When the script engine is evaluating a script file, the engine queries the script debugger to determine if the current location represents a breakpoint. If it does represent a breakpoint, the engine halts the script thread at the breakpoint location; otherwise, the engine continues. For each line in the script file, the engine queries the script debugger to determine if the current location represents a breakpoint.

When you create breakpoints, you must specify the full path to the script file in the context of the containing cartridge module.

You can optionally set a 'condition expression' when creating a breakpoint. When evaluating a breakpoint, the engine honors the breakpoint if the 'condition expression' evaluates to 'true'.

The following examples show how you can create breakpoints, get breakpoints, and remove breakpoints.

Example 1: Create Breakpoints


REQUEST:
POST /s/-/dw/debugger/v1_0/breakpoints     
{
  "breakpoints":
  [
    {
      "line_number":18,
      "script_path":"/app_storefront_controllers/cartridge/controllers/Cart.js"
    },
    {
      "line_number":25,
      "script_path":"/app_storefront_controllers/cartridge/scripts/models/CartModel.js"
    }
  ]
}

RESPONSE:
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
{
  "_v":"2.0"
  "breakpoints":
  [
    {
      "id":1,
      "line_number":18,
      "script_path":"/app_storefront_controllers/cartridge/controllers/Cart.js"
    },
    {
      "id":2,
      "line_number":25,
      "script_path":"/app_storefront_controllers/cartridge/scripts/models/CartModel.js"
    }
  ]
}

Note: To create a single breakpoint, it must be an element in a JSON collection.

Example 2: Create conditional Breakpoints


REQUEST:
POST /s/-/dw/debugger/v1_0/breakpoints     
{
  "breakpoints":
  [
    {
      "condition":"product.isOnline() == true",
      "line_number":18,
      "script_path":"/app_storefront_controllers/cartridge/controllers/Cart.js"
    },
    {
      "condition":"product.isOnline() == true",
      "line_number":25,
      "script_path":"/app_storefront_controllers/cartridge/scripts/models/CartModel.js"
    }
  ]
}

RESPONSE:
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
{
  "_v":"2.0"
  "breakpoints":
  [
    {
      "condition":"product.isOnline() == true",
      "id":1,
      "line_number":18,
      "script_path":"/app_storefront_controllers/cartridge/controllers/Cart.js"
    },
    {
      "condition":"product.isOnline() == true",
      "id":2,
      "line_number":25,
      "script_path":"/app_storefront_controllers/cartridge/scripts/models/CartModel.js"
    }
  ]
}

Note: When using conditional breakpoints, the breakpoint is honored when the condition expression evaluates to true.

Example 3: Get breakpoints (no breakpoint identifer)


REQUEST:
GET /s/-/dw/debugger/v1_0/breakpoints     

RESPONSE:
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
{
  "_v":"2.0"
  "breakpoints":
  [
    {
      "id":1,
      "line_number":18,
      "script_path":"/app_storefront_controllers/cartridge/controllers/Cart.js"
    },
    {
      "id":2,
      "line_number":25,
      "script_path":"/app_storefront_controllers/cartridge/scripts/models/CartModel.js"
    }
  ]
}

Example 4: Get breakpoints with breakpoint identifer


REQUEST:
GET /s/-/dw/debugger/v1_0/breakpoints/1     

RESPONSE:
HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
{
  "_v":"2.0"
  "id":1,
  "line_number":18,
  "script_path":"/app_storefront_controllers/cartridge/controllers/Cart.js"
}

Example 5: Remove All Breakpoints


REQUEST:
DELETE /s/-/dw/debugger/v1_0/breakpoints/

RESPONSE:
HTTP/1.1 204 No Content
Content-Length: 0

Example 6: Remove a Single Breakpoint


REQUEST:
DELETE /s/-/dw/debugger/v1_0/breakpoints/1

RESPONSE:
HTTP/1.1 204 No Content
