Vscode Httpyac Config

VSCode httpYac Configuration

About This Skill

Transform API documentation into executable, testable .http files with httpYac. This skill provides workflow guidance for creating production-ready API collections with scripting, authentication, environment management, and CI/CD integration.

When to Use This Skill

• API Documentation → Executable Files: Converting API specs (Swagger, Postman, docs) to httpYac format
• Authentication Implementation: Setting up OAuth2, Bearer tokens, or complex auth flows
• Large Collections: Organizing 10+ endpoints with multi-file structure
• Request Chaining: Passing data between requests (login → use token → create → update)
• Environment Management: Dev/test/production environment switching
• Team Workflows: Git-based collaboration with secure credential handling
• CI/CD Integration: Automated testing in GitHub Actions, GitLab CI, etc.

Expected Outcomes

• ✅ Working .http files with correct httpYac syntax
• ✅ Environment-based configuration (.env files, .httpyac.json)
• ✅ Secure credential management (no secrets in git)
• ✅ Request chaining and response validation
• ✅ Team-ready structure with documentation
• ✅ CI/CD pipeline integration (optional)

Core Workflow

Phase 1: Discovery and Planning

Objective: Understand API structure and propose file organization.

Key Questions:

1. How many endpoints? (< 20 = single file, 20+ = multi-file)
2. Authentication method? (Bearer, OAuth2, API Key, Basic Auth)
3. Environments needed? (dev, test, staging, production)
4. Existing docs? (Swagger, Postman collection, documentation URL)

Propose Structure to User:

Identified API modules:
- Authentication (2 endpoints)
- Users (5 endpoints)
- Articles (3 endpoints)

Recommended: Multi-file structure
- auth.http
- users.http
- articles.http

Proceed with this structure?

📖 Detailed Guide: references/WORKFLOW_GUIDE.md

Phase 2: Template-Based File Creation

🚨 MANDATORY: Always start with templates from assets/ directory.

Template Usage Sequence:

1. Read assets/http-file.template
2. Copy structure to target file
3. Replace {{PLACEHOLDER}} variables
4. Add API-specific requests
5. Verify syntax against references/SYNTAX.md

Available Templates:

• assets/http-file.template → Complete .http file structure
• assets/httpyac-config.template → Configuration file
• assets/env.template → Environment variables

Key Files to Create:

• .http files → API requests
• .env → Environment variables (gitignored)
• .env.example → Template with placeholders (committed)
• .httpyac.json → Configuration (optional)

Phase 3: Implement Authentication

Select Pattern Based on API Type:

Quick Example:

# @name login
POST {{baseUrl}}/auth/login
Content-Type: application/json

{
  "email": "{{user}}",
  "password": "{{password}}"
}

{{
  // Store token for subsequent requests
  if (response.statusCode === 200) {
    exports.accessToken = response.parsedBody.access_token;
    console.log('✓ Token obtained');
  }
}}

###

# Use token in protected request
GET {{baseUrl}}/api/data
Authorization: Bearer {{accessToken}}

📖 Complete Patterns: references/AUTHENTICATION_PATTERNS.md Search Pattern: grep -n "Pattern [0-9]:" references/AUTHENTICATION_PATTERNS.md

⚠️ CRITICAL SYNTAX RULES

🎯 Variable Management (Most Common Mistake)

1. Environment Variables (from .env file)

@baseUrl = {{API_BASE_URL}}
@token = {{API_TOKEN}}

✅ Use @variable = {{ENV_VAR}} syntax at file top

2. Utility Functions (in script blocks)

{{
  // ✅ CORRECT: Export with exports.
  exports.validateResponse = function(response, actionName) {
    return response.statusCode === 200;
  };
}}

###

GET {{baseUrl}}/api/test

{{
  // ✅ CORRECT: Call WITHOUT exports.
  if (validateResponse(response, 'Test')) {
    console.log('Success');
  }
}}

3. Response Data (post-response only)

GET {{baseUrl}}/users

{{
  // ✅ Store for next request
  exports.userId = response.parsedBody.id;
}}

❌ FORBIDDEN

{{
  // ❌ WRONG: Don't use exports/process.env for env vars
  exports.baseUrl = process.env.API_BASE_URL;  // NO!

  // ❌ WRONG: Don't use exports when calling
  if (exports.validateResponse(response)) { }  // NO!
}}

🔍 Post-Creation Checklist

• Template used as base
• ### delimiter between requests
• Variables: @variable = {{ENV_VAR}}
• Functions exported: exports.func = function() {}
• Functions called without exports
• .env.example created
• No secrets in .http files

Format Optimization for httpbook UI

Clean, Scannable Structure

# ============================================================
# Article Endpoints - API Name
# ============================================================
# V1-Basic | V2-Metadata | V3-Full Content⭐
# Docs: https://api.example.com/docs
# ============================================================

@baseUrl = {{API_BASE_URL}}

### Get Articles V3 ⭐

# @name getArticlesV3
# @description Full content + Base64 HTML | Requires auth | Auto-decode
GET {{baseUrl}}/articles?page=1
Authorization: Bearer {{accessToken}}

Format Guidelines

DO:

• ✅ Use 60-character separators: # =============
• ✅ Inline descriptions with |: Detail 1 | Detail 2
• ✅ @description for hover details
• ✅ Emoji for visual cues: ⭐⚠️📄

DON'T:

• ❌ 80+ character separators
• ❌ HTML comments <!-- --> (visible in UI)
• ❌ Multi-line documentation blocks
• ❌ Excessive ### decorations

Security Configuration

Essential .gitignore

# httpYac: Protect secrets
.env
.env.local
.env.*.local
.env.production

# httpYac: Ignore cache
.httpyac.cache
*.httpyac.cache
httpyac-output/

Security Rules

ALWAYS:

• ✅ Environment variables for secrets
• ✅ .env in .gitignore
• ✅ .env.example without real secrets
• ✅ Truncate tokens in logs: token.substring(0, 10) + '...'

NEVER:

• ❌ Hardcode credentials in .http files
• ❌ Commit .env files
• ❌ Log full tokens/secrets
• ❌ Disable SSL in production

📖 Complete Guide: references/SECURITY.md Search Pattern: grep -n "gitignore\|secrets" references/SECURITY.md

Implementation Notes

Before Generating Files:

• Confirm structure with user
• Validate API docs completeness
• Verify authentication requirements

While Generating:

• Always use templates from assets/
• Validate syntax before writing
• Include authentication where needed
• Add assertions for critical endpoints

After Generation:

• Show created structure to user
• Test at least one request
• Highlight next steps (credentials, testing)
• Offer to add more endpoints

Common User Requests:

• "Add authentication" → Load references/AUTHENTICATION_PATTERNS.md → Choose pattern
• "Not working" → Check: variables defined, {{ }} syntax, .env loaded
• "Chain requests" → Use # @name and exports variables
• "Add tests" → Add {{ }} block with assertions
• "CI/CD setup" → Load references/CLI_CICD.md → Provide examples
