AXICOV CLI

A comprehensive developer guide for the Axicov CLI tool - your complete solution for project deployment with configuration metadata and automated packaging.

Axicov CLI is a powerful command-line tool designed to streamline the deployment process for projects in Axicov. It automatically validates your langchain project configuration, processes environment variables, extracts README content, creates optimized zip archives, and deploys everything to your specified API endpoint.

What Axicov CLI Does

  • Configuration Validation: Ensures your project configuration is correct

  • Automated Deployment: Deploys metadata and project files to Axicov's store

  • Type Safety: Full TypeScript support with proper type definitions

Built for Performance

This CLI is optimized for Bun runtime but works seamlessly with Node.js, providing fast execution and native TypeScript support.

Getting Started

Prerequisites

  • Node.js 16.0.0 or higher (or Bun runtime)

  • npm, yarn, or bun package manager

  • A project with configuration files

Quick Start

# Install globally
npm install -g @axicov/cli

# Initialize a new project
axicov init my-project

# Deploy your project
axicov deploy -k "your-api-key"

Installation

Global Installation (Recommended, but look for version upgrades soon)

# Using npm
npm install -g @axicov/cli

# Using yarn  
yarn global add @axicov/cli

# Using bun
bun install -g @axicov/cli

Local Installation

# Using npm
npm install @axicov/cli --save-dev

# Using yarn

# Using bun
bun add @axicov/cli --dev

Verify Installation

axicov --version
# Output: 1.0.2

Configuration

Configuration File

Axicov requires an axicov.config.ts (or axicov.config.js) file in your project root. This file defines your project metadata and deployment settings.

Basic Configuration

// axicov.config.ts
const axicovConfig = {
  name: "my-axicov-project",
  description: "A modern TypeScript application with best practices",
  readmePath: "./README.md",
  env: "./.env",
  
  params: {
    version: {
      type: String,
      description: "Project version",
      required: true
    },
    author: {
      type: String,
      description: "Project author",
      required: false
    },
    license: {
      type: String,
      description: "Project license",
      required: false
    }
  },
  
  port: 3000,
  tags: ["TypeScript", "Node.js", "Web Application"]
};

export default axicovConfig;

LangChain TypeScript Configuration

// axicov.config.ts for LangChain projects
const axicovConfig = {
  name: "langchain-ai-app",
  description: "A LangChain TypeScript application for building AI-powered solutions",
  readmePath: "./README.md",
  env: "./.env",
  
  params: {
    prompt: {
      type: String,
      description: "The prompt that the LLM will respond to",
      required: false
    },
    temperature: {
      type: Number,
      description: "LLM temperature setting (0.0 to 1.0)",
      required: false
    },
    maxTokens: {
      type: Number,
      description: "Maximum tokens for LLM responses",
      required: false
    }
  },
  
  port: 3000,
  tags: ["LangChain", "TypeScript", "AI", "LLM", "Vector Store"]
};

export default axicovConfig;

Troubleshooting

Common Issues and Solutions

1. Configuration File Not Found

Error:

Configuration file not found. Looking for: axicov.config.ts or axicov.config.js in /path/to/project

Solutions:

  • Run axicov init to create the configuration file

  • Ensure you're in the correct project directory

  • Check file naming: must be exactly axicov.config.ts or axicov.config.js

2. Invalid Configuration Structure

Error:

Configuration validation failed
   • 'params' must be an object, got array
   • params.version.type must be String or Number constructor

Solutions:

  • Verify parameter definitions follow the correct structure:

    params: {  fieldName: {    type: String,           // Must be String or Number constructor    description: string,    // Must be a string    required: boolean      // Must be true or false  }}

  • Check that all required fields are present and have correct types

3. Environment File Issues

Error:

Environment file not found: /path/to/.env

Solutions:

  • Create the .env file: touch .env

  • Check the path in your config file matches the actual file location

  • Ensure proper file permissions (readable)

Environment parsing errors:

Warning: Invalid env line 5 in .env: "INVALID_LINE_WITHOUT_EQUALS"

Solutions:

  • Each line should follow format: KEY=value

  • Use # for comments

  • Quote values with spaces: KEY="value with spaces"

4. Port Configuration Issues

Error:

'port' must be between 1 and 65535, got 70000

Solutions:

  • Choose a port in valid range: 1-65535

  • Recommended: Use ports > 1024 to avoid system port conflicts

  • Common choices: 3000, 8080, 8000, 5000

5. API Deployment Failures

Error:

API request failed: 401 Unauthorized
Response: {"error": "Invalid API key"}

Solutions:

  • Verify your API key is correct and active

  • Check if the API key has proper permissions

  • Ensure you're using the correct API endpoint

Error:

Failed to deploy: fetch failed

Solutions:

  • Check internet connectivity

  • Verify the API endpoint is accessible

  • Ensure no firewall blocking outbound requests

6. File Permission Issues

Error:

Output directory is not writable: /path/to/dist

Solutions:

  • Create the directory: mkdir -p dist

  • Fix permissions: chmod 755 dist

  • Use a different output path: -o "./build"

7. Large Project Zipping Issues

Error:

Archive size: 150.2 MB
Warning: Large archive may cause deployment issues

Solutions:

  • Review your .gitignore to exclude unnecessary files:

    node_modules/dist/*.log.DS_Storecoverage/

  • Remove large files that aren't needed for deployment

  • Consider using compression level 9: modify source code or use custom build

8. Configuration validation error

You can get a message like this:

Configuration validation failed
   • Failed to load configuration: Error loading config file: Failed to load config file. ES module error: Unexpected token 'export'. CommonJS error: Unexpected token 'export'
✖ Deployment failed

to fix this, change this line in axicov.config.ts 

export default axicovConfig

to,

module.exports = axicovConfig;

Debug Mode

Enable verbose output for detailed troubleshooting:

axicov deploy -k "your-key" -v

This shows:

  • Full configuration details

  • Complete metadata JSON

  • File scanning progress

  • API request/response details

Getting Help

If you encounter issues not covered here:

  1. Check the documentation in your project's README

  2. Verify all requirements are met (Node.js version, file structure)

  3. Test with a minimal project to isolate the issue

  4. Check API endpoint status if deployment fails

Best Practices

1. Project Organization

Recommended Structure:

your-project/
├── axicov.config.ts          # Keep config in TypeScript
├── README.md                 # Comprehensive documentation
├── .env                      # Production environment
├── .env.example              # Template for other developers
├── .gitignore               # Properly configured
├── src/                     # Source code
├── tests/                   # Test files
└── docs/                    # Additional documentation

2. Configuration Management

Type-Safe Configurations:

// Use TypeScript for better IDE support and validation
const axicovConfig = {
  // Use descriptive names
  name: "user-authentication-service",
  
  // Write clear descriptions
  description: "Handles user registration, login, and JWT token management",
  
  // Use consistent paths
  readmePath: "./README.md",
  env: "./.env",
  
  // Document parameters thoroughly
  params: {
    jwtSecret: {
      type: String,
      description: "Secret key for JWT token signing and verification",
      required: true
    },
    tokenExpiry: {
      type: String,
      description: "JWT token expiration time (e.g., '7d', '24h')",
      required: false
    }
  }
};

3. Environment Variables

Security Best Practices:

# .env - Production values
NODE_ENV=production
JWT_SECRET=your-super-secret-production-key
DATABASE_URL=postgresql://user:password@prod-db:5432/app

# Don't commit sensitive values!
# Use .env.example for templates
# .env.example - Template for developers
NODE_ENV=development
JWT_SECRET=development-secret-change-in-production
DATABASE_URL=postgresql://localhost:5432/app_dev

Organization:

# Group related variables
# === Database Configuration ===
DATABASE_URL=postgresql://localhost:5432/myapp
DATABASE_POOL_SIZE=10
DATABASE_TIMEOUT=30000

# === Authentication ===
JWT_SECRET=your-jwt-secret
JWT_EXPIRY=7d
BCRYPT_ROUNDS=12

# === External APIs ===
OPENAI_API_KEY=sk-...
STRIPE_SECRET_KEY=sk_...
SENDGRID_API_KEY=SG...

4. README Documentation

Structure your README.md:
