Frontend App Manifest

manifest.json identifies the app and controls how Corva runs it. The scaffolder creates this file from the values registered in Dev Center.

Generated example

JSON does not support comments. Keep explanatory notes outside the file.

Identity and discovery

Field	Purpose	Change carefully?
application.type	Must be ui for a frontend app	Do not change
application.key	Registered identifier used for packages and app instances	Do not change
application.name	Customer-facing name	Yes
application.description	Full app description	Yes
application.summary	Short store and discovery summary	Yes
application.category	App-store category	Coordinate with the registered app
application.visibility	App visibility	Manage through the supported publishing flow

Segment

Use one operational segment for a focused customer experience:

"segments": ["drilling"]

or:

"segments": ["completion"]

Corva UI uses the segment to select the primary assets and header behavior. Drilling maps to a rig and well; completion maps to a frac fleet, pad, and wells.

UI fields

Field	Purpose
initial_size.w	Initial dashboard width in a 12-column grid
initial_size.h	Initial dashboard height in grid units
multi_rig	Removes normal single-asset assumptions; the app must load its own asset scope
full_screen_report	Uses the full report page when exporting dashboard PDF output
use_app_header_v3	Enables the current AppHeader implementation
multi_rig_on_chipless_dashboard	Applies multi-rig behavior only on chipless dashboards

Keep use_app_header_v3 set to true for new apps.

Completion-only fields

Field	Purpose
completionAppType	Selects the supported pad, frac, wireline, pumpdown, single-well, or multi-well modes
enableSimulFracInPadSelect	Adds frac-fleet line selection when SimulFrac relationships are available
disableActiveWellsInPadSelect	Prevents selection of wells that are not active

The default completionAppType in Corva UI is Frac Multi-Well Apps.

See Build a Completion UI App before changing these fields.

Entrypoint

The frontend entrypoint should remain:

{
  "entrypoint": {
    "file": "src/index.js",
    "function": "handler"
  },
  "runtime": "ui"
}

The generated build and package flow relies on this shape.
