# ui5-modernization

A plugin that modernizes SAPUI5 and OpenUI5 apps: runs the UI5 linter, then fixes deprecated APIs and global access phase by phase.

## What it does

The plugin is built on `@ui5/linter`. The linter does two jobs here: it reports deprecated APIs, global namespace access and other incompatibilities, and it confirms afterwards that nothing is left. Rule IDs such as `no-deprecated-api` and `no-globals` point to the skill that handles that category.

The entry point is `/modernize-ui5-app`. It asks which verification mode you want — full autonomous, half autonomous or manual — then walks through five phases: linter autofix plus test starter restructure, `manifest.json` and `Component.js`, the module system (globals, pseudo modules, cyclic dependencies, linter blind spots), deprecated API replacement, and CSP compliance. Every phase lands as its own git commit, so `git revert HEAD` undoes the last one. Start from a clean working directory.

The target is manifest version 2.0.0 with framework version 1.136.0 or newer. Some problems the linter never reports: runtime-only patterns and circular dependencies. Detection scripts inside the plugin cover those. You can also call a single skill when one error pattern is all you have. The workflow leaves `node_modules/`, `dist/` and build artifacts alone.

### GitHub Copilot

**Command from the source**
```bash
copilot plugin install ui5-modernization@awesome-copilot
```

## When to use it
- swap deprecated APIs for their current equivalents
- remove global namespace access from JS and XML files
- move QUnit and OPA5 tests onto Test Starter
- untangle circular `sap.ui.define` dependencies
- bring `manifest.json` and `Component.js` up to date

## Example prompts
- Run `/modernize-ui5-app` and ask me which verification mode to pick
- Fix `no-globals` errors in my XML views with `/fix-xml-globals`
- Clean up deprecated controls using `/fix-deprecated-controls`

# UI5 Modernization Plugin

A comprehensive plugin providing a complete toolkit for modernizing SAPUI5/OpenUI5 applications.

## Overview

This plugin provides:

- **Autonomous modernization workflow** with end-to-end orchestration in five phases
- **Specialized fix skills** for every UI5 linter rule category
- **Verification gates** at every phase boundary (full autonomous, half autonomous, or manual)
- **Validation** at every step via UI5 linter integration

## Installation

### Claude Code CLI

```bash
claude plugin install ui5-modernization@claude-plugins-official
```

Use the `/plugin` command if you already started an interactive Claude Code CLI session.

```bash
/plugin install ui5-modernization@claude-plugins-official
```

### GitHub Copilot CLI

```bash
copilot plugin install ui5-modernization@awesome-copilot
```

Use the `/plugin` command if you already started an interactive GitHub Copilot CLI session.

```bash
/plugin install ui5-modernization@awesome-copilot
```

### Installing Skills Only

If your coding agent doesn't support plugins, install the skills directly using the [skills](https://www.npmjs.com/package/skills) package:

```bash
npx skills add UI5/plugins-coding-agents
```

> **Note:** You need to install the [UI5 MCP server](https://github.com/UI5/mcp-server) manually when installing the skills only.

## How It Works

The goal is to modernize your OpenUI5/SAPUI5 app — targeting manifest version 2.0.0 with a minimum framework version of 1.136.0. This means replacing deprecated APIs with their modern equivalents and enforcing strict module imports, eliminating reliance on globals and legacy patterns.

This plugin is built around the [UI5 linter](https://github.com/UI5/linter) (`@ui5/linter`) — a static analysis tool that detects deprecated APIs, global namespace access, and other incompatibilities. The linter serves two roles in the modernization workflow:

1. **Detection** — Each skill reads linter output to identify what needs fixing. The linter's rule IDs (e.g., `no-deprecated-api`, `no-globals`) map directly to specific fix skills.
2. **Verification** — After applying fixes, the linter is re-run to confirm errors are resolved. Zero remaining errors = phase complete.

A few issues cannot be detected by the linter (runtime-only patterns, cyclic dependencies). For these, the plugin includes its own detection scripts that fill the gap.

## Quick Start

### 1. Start With the Modernization Workflow

The main entry point is the orchestrator which runs all five phases:

```
/modernize-ui5-app
```

This will:
1. Ask which verification mode you want (full autonomous / half autonomous / manual)
2. Run Phase 1: UI5 linter autofix + test starter restructure
3. Run Phase 2: manifest.json + Component.js foundation
4. Run Phase 3: module system (globals, pseudo modules, cyclic dependencies, blind spots)
5. Run Phase 4: deprecated API replacements
6. Run Phase 5: CSP compliance
7. Generate `MODERNIZATION-REPORT.md` and `MODERNIZATION-ISSUES.md`

Each phase creates a git commit and runs the verification gate per your chosen mode.

### 2. Use Specialized Skills for Specific Issues

When you encounter specific error patterns, use the targeted skills directly:

```
# Test infrastructure (Phase 1)
/modernize-test-starter           # Test Starter modernization

# Foundation (Phase 2)
/fix-component-async              # Component.js async issues
/fix-manifest-json                # manifest.json issues

# Module system issues (Phase 3)
/fix-js-globals                   # no-globals errors in JS files
/fix-xml-globals                  # no-globals errors in XML views/fragments
/fix-pseudo-modules               # no-pseudo-modules, no-implicit-globals
/fix-linter-blind-spots           # Runtime patterns linter misses
/fix-cyclic-deps                  # Circular sap.ui.define dependencies

# Deprecated API modernizations (Phase 4)
