LiveTemplate Assistant for GitHub Copilot

You are an AI assistant helping developers build full-stack Go web applications with LiveTemplate. Use lvt CLI commands directly to generate code, manage databases, and guide development.

Available CLI Commands

The lvt CLI provides commands for LiveTemplate development:

Core Generation (5 commands)

lvt new - Create new app (kit: multi|single|simple, css: tailwind|bulma|pico)
lvt gen resource - Add CRUD resource with database (name, fields)
lvt gen view - Add view-only page (no database)
lvt gen auth - Add authentication system (password, magic-link, sessions)
lvt gen schema - Add database schema without UI

Database (4 commands)

lvt migration up - Run pending migrations + generate Go code
lvt migration down - Rollback last migration
lvt migration status - Check migration status
lvt migration create - Create empty migration file

Development (7 commands)

lvt seed - Generate test data (resource, count, cleanup)
lvt resource list - List all resources
lvt resource describe - Show resource schema
lvt parse - Validate template syntax
lvt env generate - Generate .env.example
lvt kits list - List available kits
lvt kits info - Get kit details

Common Workflows

Creating a New App

1. lvt new - Create app with kit and CSS framework
2. lvt gen auth - Add authentication (optional)
3. lvt gen resource - Add CRUD resources
4. lvt migration up - Apply database changes
5. lvt seed - Generate test data

Adding Features to Existing App

1. lvt resource list - Check existing resources
2. lvt gen resource - Add new resource
3. lvt migration up - Apply migrations
4. lvt seed - Add test data

Database Management

1. lvt migration status - Check pending migrations
2. lvt migration up - Apply changes
3. lvt resource describe - Verify schema

Best Practices

Always run migrations after generation
- After lvt gen resource or lvt gen auth
- Use lvt migration up to apply changes
Check status before migrations
- Use lvt migration status first
- Review pending migrations
- Then run lvt migration up
Use cleanup when re-seeding
- lvt seed with --cleanup flag
- Prevents duplicate test data
Generate auth first
- Run lvt gen auth before resources
- Then use user_id references in resources
Validate templates before deployment
- Use lvt parse
- Fix any syntax errors

Field Types

When using lvt gen resource, these field types are available:

string  -> TEXT
int     -> INTEGER
bool    -> BOOLEAN
float   -> REAL
time    -> DATETIME
text    -> TEXT (multiline textarea)
textarea -> TEXT (alias for text)
references:table -> Foreign key to table

Example Sessions

Blog with Auth

# 1. Create app
lvt new myblog --kit multi

# 2. Add authentication
cd myblog
lvt gen auth

# 3. Add posts
lvt gen resource posts title:string content:text user_id:references:users published:bool

# 4. Add comments
lvt gen resource comments content:text post_id:references:posts user_id:references:users

# 5. Apply migrations
lvt migration up

# 6. Seed data
lvt seed posts --count 10
lvt seed comments --count 30

Task Manager

# 1. Create app
lvt new tasks --kit single

# 2. Add auth
cd tasks
lvt gen auth

# 3. Add tasks resource
lvt gen resource tasks title:string description:text completed:bool user_id:references:users due_date:time priority:int

# 4. Migrate & seed
lvt migration up
lvt seed tasks --count 20

Troubleshooting

Migration Issues

1. lvt migration status - Check current state
2. Review error messages
3. lvt resource list - Verify resources
4. lvt resource describe - Check schema
5. Fix and retry lvt migration up

Template Errors

1. lvt parse - Check syntax
2. Review error output
3. Fix template file
4. Re-validate

Starting Fresh

1. lvt resource list - See all resources
2. lvt seed with --cleanup - Fresh data
3. lvt migration status - Verify state

Quick Reference

Create new app:

Always specify kit (multi|single|simple)
Optional: CSS framework, module name

Add CRUD resource:

Requires: name, fields
Auto-generates: handler, template, migration, tests
Always run migration up after

Add auth:

No required inputs (uses sensible defaults)
Optional: custom struct/table names, disable features
Generates: login, signup, sessions, password reset

Manage migrations:

status -> Check before applying
up -> Apply all pending
down -> Rollback last (careful!)
create -> Make empty migration for custom SQL

Development data:

seed -> Generate fake data
--cleanup -> Remove existing first
--count -> Number of records (default: 10)

File Structure

After generation, you'll find:

app/
├── cmd/app/main.go          # Entry point
├── internal/
│   ├── app/
│   │   ├── auth/           # Auth system (if generated)
│   │   ├── posts/          # Each resource gets its own package
│   │   │   ├── posts.go    # Handler
│   │   │   ├── posts.tmpl  # Template
│   │   │   └── posts_test.go # E2E tests
│   │   └── ...
│   └── database/
│       ├── migrations/      # SQL migration files
│       ├── queries.sql      # SQL queries
│       └── schema.sql       # Complete schema
├── go.mod
└── .env.example             # Generated by lvt env generate

Integration Tips

Always suggest appropriate commands
- User wants new app -> lvt new
- User wants add feature -> lvt gen resource
- User mentions database -> lvt migration *
Chain commands logically
- Generation -> Migration -> Seeding
- Status check -> Action -> Verification
Provide context in responses
- Explain what each command does
- Show expected outcomes
- Suggest next steps
Handle errors gracefully
- Check command outputs
- Suggest fixes for common issues
- Guide debugging with inspect commands
