# backend-nestjs output preview
## PART A: Task fit
- Use case: NestJS backend development patterns. Use when developing backend APIs with NestJS, TypeORM/Prisma, and TypeScript. Use when developing backend code in a NestJS project with TypeScript. runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more..
- Inputs: target material, constraints, expected output, and acceptance criteria.
- Evidence boundary: follow “When to Use This Skill / Recommended Project Structure / Conventions” and do not present inference as author intent.
## PART B: Execution result
- **01** The card summarizes the use case; runtime output centers on “NestJS backend development patterns. Use when developing backend APIs with NestJS, TypeORM/Prisma, and TypeScript. Use when developing backend code in a NestJS project with TypeScript. runs entirely locally. Works with Claude Code, Cursor, Cline and 23 more.”.
- **02** When the source has headings, the agent prioritizes “When to Use This Skill / Recommended Project Structure / Conventions” so the result follows the author’s structure.
- **03** Typical output includes task judgment, concrete steps, required commands or file edits, validation, and follow-up options.
- **04** Risk context follows the fingerprint: read files, write/modify files; mostly runs locally; usually needs no extra API key.
## Running Rules
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding scope.
- Return the result, validation criteria, and next iteration options. The source does not require a stable slash command. After installation, invoke the skill by name and describe the task.
Name target files or source material, expected output, forbidden changes, and whether network or shell access is allowed. Permission fingerprint: read files, write/modify files.
Start with a small task and check whether the result follows “When to Use This Skill / Recommended Project Structure / Conventions”. Inspect diffs, logs, previews, or tests before expanding scope.
Confirm the final output includes a concrete result, evidence, and next action. If it stays generic, tighten inputs, boundaries, and acceptance criteria.

# backend-nestjs
## When to use
- NestJS backend development patterns. Use when developing backend APIs with NestJS, TypeORM/Prisma, and TypeScript. Use…
- Use it when the task has clear inputs, repeatable steps, and validation criteria.
## What to provide
- Target material, scope, expected result, and forbidden changes.
- Whether network, commands, file writes, or external services are allowed.
## Execution rules
- Organize steps around “When to Use This Skill / Recommended Project Structure / Conventions” and keep inference separate from source facts.
- read files, write/modify files; mostly runs locally; usually needs no extra API key.
- Validate with a small sample before expanding the task.
## Output requirements
- Return the deliverable, key evidence, validation method, and next action.
- Mark missing information as unknown; do not invent commands, platforms, or dependencies. The author source anchors workflow facts; repository files anchor sources and commands; Fluxly only adds fit, limitations, and quality judgment.
skill "backend-nestjs" {
input -> user goal + target files + boundaries + acceptance criteria
context -> When to Use This Skill / Recommended Project Structure / Conventions
rules -> SKILL.md triggers / order / output contract
runtime -> no special runtime | read files, write/modify files | mostly runs locally
guardrails -> usually needs no extra API key + small-sample validation + diff/log review
output -> copyable result + checklist + next iteration

When to Use This Skill
Use when developing backend code in a NestJS project with TypeScript.

Conventions
- One use case per file in
application/ - DTOs with class-validator decorators in
presentation/ - Repository pattern for data access in
infrastructure/ - Module-scoped providers; export only what's needed
Testing
- Stack: Vitest (preferred) or Jest
- Unit test use cases with mocked dependencies
- Test file next to source:
*.spec.ts - All tests in English
- Naming: "should do X when Y"
Commands
pnpm dev # Development with hot reload
pnpm build # Production build
pnpm lint # ESLint
pnpm test # Run tests
pnpm test:cov # Coverage report
Error Handling
- Use NestJS built-in exceptions (BadRequestException, NotFoundException, etc.)
- Custom exceptions extend HttpException
- Global exception filter for unhandled errors
Database
- Use query builder or repository pattern
- Always use transactions for multi-table writes
- Add indexes for frequently queried columns
- Use database MCPs to inspect schema before writing queries
Pre-commit Checklist
- Build passes? (
pnpm build) - Lint passes? (
pnpm lint) - Tests pass? (
pnpm test) - DTOs have proper validation?
- Error cases handled?
