Fix Manifest JSON

Fix manifest.json

This skill fixes manifest.json issues that the UI5 linter detects but cannot auto-fix because they may require understanding of the application's dependencies and structure.

Linter Rules Handled

When to Use

Apply this skill when you see linter output like:

manifest.json:2:3 error manifest.json must be modernized to Version 2  no-outdated-manifest-version
manifest.json:15:5 error Use UI5 version 1.136.0 or higher in manifest.json  no-legacy-ui5-version-in-manifest
manifest.json:20:7 error Use of deprecated library 'sap.ui.commons'  no-deprecated-library
manifest.json:25:7 error Use of deprecated view type 'JSON'  no-deprecated-api
manifest.json:30:9 error Property '/sap.ui5/rootView/async' has been removed in Manifest Version 2  no-removed-manifest-property

Fix Strategy

1. no-outdated-manifest-version - Update _version to 2.0.0

IMPORTANT: Only update the root _version to "2.0.0". Do NOT change nested _version properties inside sap.app, sap.ui, sap.ui5, etc. — those should remain at their current values (e.g., "1.1.0", "1.2.0").

// Before
{
  "_version": "1.12.0",
  "sap.app": {
    "_version": "1.1.0",
    ...
  },
  "sap.ui5": {
    "_version": "1.2.0",
    ...
  }
}

// After — only root _version changed
{
  "_version": "2.0.0",
  "sap.app": {
    "_version": "1.1.0",
    ...
  },
  "sap.ui5": {
    "_version": "1.2.0",
    ...
  }
}

After updating to version 2.0.0, you MUST also apply these consequential changes:

• Remove async properties (see section 6)
• Rename routing configuration properties (see section 8)
• Add type: "View" to routing config or targets (see section 8)

2. no-legacy-ui5-version-in-manifest - Update minUI5Version

// Before
"dependencies": {
  "minUI5Version": "1.120.0",
  ...
}

// After
"dependencies": {
  "minUI5Version": "1.136.0",
  ...
}

If minUI5Version is an array, update all entries below 1.136.0.

3. no-deprecated-library - Remove Deprecated Libraries

Remove these deprecated libraries from sap.ui5/dependencies/libs:

• sap.ui.commons - Use sap.m instead
• sap.ui.ux3 - Use sap.m and sap.f instead
• sap.makit - Use sap.viz instead
• sap.me - Use sap.m instead
• sap.ca.ui - Use standard controls
• sap.landvisz - Deprecated
• sap.ui.vtm - Deprecated
• sap.sac.grid - Deprecated since 1.112, removed 1.114
• sap.ui.suite - Deprecated since 1.108
• sap.zen.commons - Deprecated since 1.89
• sap.zen.crosstab - Deprecated since 1.89
• sap.zen.dsh - Deprecated since 1.89

// Before
"libs": {
  "sap.m": {},
  "sap.ui.commons": {},
  "sap.ui.layout": {}
}

// After
"libs": {
  "sap.m": {},
  "sap.ui.layout": {}
}

4. no-deprecated-component - Remove Deprecated Components

Remove deprecated components from sap.ui5/dependencies/components.

5. no-deprecated-api - Fix View Types

Change deprecated view types to "XML" (or "Typed" for JS-heavy view cases):

• JSON → XML
• HTML → XML
• JS → XML (or consider Typed view as an alternative for complex JS logic)
• Template → XML

Applies to:

• sap.ui5/rootView/type
• sap.ui5/routing/config/viewType
• sap.ui5/routing/targets/*/viewType

// Before
"rootView": {
  "viewName": "my.app.view.Main",
  "type": "JSON"
}

// After
"rootView": {
  "viewName": "my.app.view.Main",
  "type": "XML"
}

Important: When changing view types, the actual view file must also be converted to XML format. Flag this for manual review.

6. no-removed-manifest-property - Remove Async Properties (Manifest v2)

In manifest version 2.0.0+, the async flag is implicitly true for the root view and the routing configuration, so it must be removed from exactly these two locations:

• sap.ui5/rootView/async
• sap.ui5/routing/config/async

// Before (v2)
"rootView": {
  "viewName": "my.app.view.Main",
  "type": "XML",
  "async": true
}

// After (v2)
"rootView": {
  "viewName": "my.app.view.Main",
  "type": "XML"
}

SCOPE WARNING — do NOT remove async from anywhere else. The implicit-async behavior applies only to rootView and routing.config. Other locations where async may legitimately appear (and must be preserved) include:

• sap.ui5/models/*/settings/async (e.g., OData/JSON model async loading flag)
• sap.app/dataSources/* settings that include async
• Any custom configuration under sap.ui5/extends, sap.ui5/componentUsages, or third-party namespaces
• Any async inside route definitions that is not the top-level routing.config.async

The linter rule no-removed-manifest-property only fires for the two paths above. Trust the linter's pointer — only remove the exact properties it flags.

7. no-deprecated-api - Remove sap.ui5/resources/js

If the array is empty, remove the entire js property (and resources if it becomes empty).

// Before
"resources": {
  "js": []
}

// After
// (resources section removed if empty)

If not empty, this requires manual modernization to proper module dependencies.

8. Routing Configuration — Rename Properties for Manifest Version 2

When _version is updated to "2.0.0", the routing configuration properties must also be renamed. The view-prefixed property names are deprecated in version 2.

Property renaming rules:

New required property:

Before (v1.x):

"routing": {
    "config": {
        "routerClass": "sap.m.routing.Router",
        "viewType": "XML",
        "viewPath": "my.app.view",
        "controlId": "app",
        "controlAggregation": "pages",
        "async": true
    },
    "routes": [
        {
            "name": "main",
            "pattern": "",
            "target": "main"
        }
    ],
    "targets": {
        "main": {
            "viewName": "Main",
            "viewId": "main",
            "viewLevel": 1
        },
        "detail": {
            "viewName": "Detail",
            "viewId": "detail",
            "viewLevel": 2
        }
    }
}

After (v2.0.0):

"routing": {
    "config": {
        "routerClass": "sap.m.routing.Router",
        "viewType": "XML",
        "path": "my.app.view",
        "controlId": "app",
        "controlAggregation": "pages",
        "type": "View"
    },
    "routes": [
        {
            "name": "main",
            "pattern": "",
            "target": "main"
        }
    ],
    "targets": {
        "main": {
            "name": "Main",
            "id": "main",
            "level": 1
        },
        "detail": {
            "name": "Detail",
            "id": "detail",
            "level": 2
        }
    }
}

Changes summary:

• viewPath → path in config
• viewName → name in each target
• viewId → id in each target
• viewLevel → level in each target
• viewType stays as viewType (unchanged)
• async removed only from routing.config (implicit true in v2). Do NOT touch async on models, dataSources, or other unrelated config — see Section 6 scope warning.
• type: "View" added to config (alternatively, add "type": "View" to each individual target if mixing views and components)

When to add type to config vs per target:

• type in config (most common): All targets are views
• type per target: Mixed routing targets (some views, some components)

Implementation Steps

1. Read and parse the manifest.json file
2. For each linter error (identified by rule ID and message):
   • no-outdated-manifest-version: Update root _version to "2.0.0" (keep nested _version values unchanged)
   • no-legacy-ui5-version-in-manifest: Update minUI5Version to "1.136.0"
   • no-deprecated-library: Remove the library from dependencies
   • no-deprecated-component: Remove the component from dependencies
   • no-deprecated-api (view type): Change to "XML"
   • no-deprecated-api (resources/js): Remove if empty
   • no-removed-manifest-property: Remove the property
3. If _version was updated to 2.0.0, also apply routing modernization:
   • Rename viewPath → path, viewName → name, viewId → id, viewLevel → level in routing config and targets
   • Add type: "View" to routing.config (or per target)
   • Remove async only from sap.ui5/rootView and sap.ui5/routing/config. Do NOT remove async from model settings, dataSources, or any other path — those keep their async flag.
4. Preserve JSON formatting (indentation)
5. Write the updated file

Notes

• Only update the root _version to 2.0.0 — do NOT change nested _version properties inside sap.app, sap.ui, sap.ui5, etc.
• When updating _version to 2.0.0, always apply routing property renames and add type: "View" in the same pass
• Changing view types from JSON/HTML/JS to XML requires the actual view files to be converted - flag this as a follow-up task
• When removing deprecated libraries, check if there are any imports from those libraries in the codebase that need modernization
• The minUI5Version update means the app won't run on older UI5 versions - this is intentional for modern UI5 compatibility
• After updating _version to 2.0.0, synchronizationMode and other v1-specific properties should also be removed if present
• Manifest v2 strictness: Manifest v2.0.0 enables stricter error handling — syntactical errors in views/fragments now throw errors instead of failing silently
• sap.ui/supportedThemes causes an error in manifest v2 — remove it if present
• IAsyncContentCreation is NOT enforced by manifest v2 — it must be explicitly added in Component.js by the fix-component-async skill (this skill does not handle it)
• Typed View alternative: When changing deprecated view types (JS, JSON, HTML) the default replacement is XML, but for complex JS-heavy views, consider Typed views as an alternative

Related Skills

• fix-component-async: After updating manifest.json, Component.js needs the IAsyncContentCreation interface — defer to that skill for correct placement
• fix-bootstrap-params: For deprecated libraries referenced in HTML bootstrap (data-sap-ui-libs), use fix-bootstrap-params instead of this skill
