UI5 Linter - Support and Community Resources

Source: https://github.com/UI5/linter/blob/main/SUPPORT.md Last Updated: 2025-11-21 UI5 Linter Version: 1.22.0

Overview

This guide helps you get support for UI5 Linter issues, connect with the community, and choose the right channel for different types of questions or problems.

⚠️ Important: Do NOT Use GitHub Issues for Questions

GitHub Issues are for:

• ✅ Bug reports (confirmed issues)
• ✅ Feature requests
• ✅ Documentation problems

GitHub Issues are NOT for:

• ❌ Setup help
• ❌ General questions ("How do I...")
• ❌ Configuration assistance
• ❌ Troubleshooting guidance
• ❌ Best practices discussions

Why: GitHub Issues are for tracking development work, not community support. Questions in issues slow down the development process.

Official Support Channels

1. StackOverflow ⭐ Recommended for Questions

URL: http://stackoverflow.com/questions/tagged/ui5-tooling

Tag: ui5-tooling

Best For:

• General questions about UI5 Linter
• Configuration help
• Troubleshooting linting issues
• Best practices
• "How do I..." questions

How to Ask:

**Title**: Clear, specific question
Example: "How do I configure UI5 Linter to ignore test files?"

**Tags**: ui5-tooling, sapui5 (or openui5)

**Question Body**:
1. What you're trying to achieve
2. What you've tried
3. What's not working
4. Relevant code/configuration
5. Environment (UI5 Linter version, Node version, OS)

Example Question:

# How do I fix no-globals rule errors in my UI5 project?

I'm getting `no-globals` rule violations when using `sap.ui.getCore()`.

## What I've Tried
- Running `ui5lint --fix` but it doesn't fix all occurrences
- Checked documentation for autofix limitations

## Configuration
```javascript
// ui5lint.config.mjs
export default {
  ignores: ["webapp/thirdparty/**"]
};

Environment

• UI5 Linter: 1.22.0
• Node.js: 20.11.0
• OS: Windows 11

Question

What are the limitations of autofix for no-globals? How do I manually fix unsupported cases?

**Why StackOverflow**:
- ✅ Answers benefit entire community (searchable)
- ✅ Expert community members can help
- ✅ Voting system highlights best answers
- ✅ Permanent knowledge base

## When to Use Each Channel

### Use StackOverflow When:
- ✅ You have a well-defined question
- ✅ Answer would benefit others (searchable)
- ✅ You need detailed, documented response
- ✅ You can wait a few hours for answer
- ✅ You want permanent reference

**Examples**:
- "How does the autofix feature work?"
- "What's the best way to configure linter for monorepo?"
- "How do I integrate UI5 Linter with ESLint?"

---

### Use Slack When:
- ✅ You need quick clarification
- ✅ You're troubleshooting in real-time
- ✅ You want to discuss approach before implementing
- ✅ You have a time-sensitive question
- ✅ You want community feedback

**Examples**:
- "Quick question: Does --fix work on manifest.json?"
- "Anyone seen this error before? [screenshot]"
- "What's the recommended ignore pattern for Fiori Elements apps?"

---

### Use GitHub Issues When:
- ✅ You found a confirmed bug
- ✅ You have feature request with detailed use case
- ✅ Documentation is incorrect or missing
- ✅ You can provide reproduction steps

**Examples**:
- "Rule no-globals doesn't detect sap.ui.getCore() in arrow functions"
- "Feature Request: Add autofix for deprecated Button.tap event"
- "Documentation: Autofix limitations page missing Core API examples"

**Process**:
1. Confirm it's actually a bug (not configuration issue)
2. Search existing issues
3. Use issue template
4. Provide reproduction steps
5. Include environment details

See [Contributing Guide](contributing.md) for full details.

Troubleshooting Before Asking

Step 1: Check Documentation

Skill References:

• SKILL.md - Main skill documentation
• Rules Reference - All 19 rules explained
• Autofix Reference - What can/can't be fixed
• CLI Options - All command-line flags
• Configuration - Config file setup
• Performance - Optimization tips

Official Docs:

• Rules Documentation

Step 2: Search Existing Issues

https://github.com/UI5/linter/issues?q=is%3Aissue+YOUR+SEARCH+TERMS

Common Searches:

• "no-globals autofix"
• "manifest version error"
• "performance slow"
• "configuration not found"

Step 3: Enable Verbose Logging

ui5lint --verbose --details

Output includes:

• Configuration loading details
• File processing information
• Rule execution details
• Detailed error messages

Step 4: Try Dry-Run for Autofix

UI5LINT_FIX_DRY_RUN=true ui5lint --fix

See what would change without modifying files.

Step 5: Isolate the Issue

Create minimal reproduction:

# Create test directory
mkdir ui5lint-test
cd ui5lint-test

# Create minimal file
cat > test.js << 'EOF'
sap.ui.define([], function() {
  return sap.ui.getCore();
});
EOF

# Test
ui5lint test.js

If issue reproduces: Great for asking help with minimal example

If issue doesn't reproduce: Problem is in your configuration or other code

Security Issues

🔒 SPECIAL PROCESS FOR SECURITY VULNERABILITIES

DO NOT:
