codeshift

Codeshift is a command-line tool to translate and transform source code files between programming languages.

Features

• Select output language to convert source code into
• Support for multiple input files
• Output results to a file or stream directly to stdout
• Customize model and provider selection for optimal performance
• Supports leading AI providers:
  • OpenAI
  • OpenRouter
  • Groq

Requirements

• Node.js (Requires Node.js 20.17.0+)
• An API key from any of the following providers:
  • OpenAI
  • OpenRouter
  • Groq
  • any other AI provider compatible with OpenAI’s chat completions API endpoint

Installation

• Run npm install -g @uday-rana/codeshift.

• Run npx codeshift. This will generate a .codeshift.config.toml file in your current directory.

• In .codeshift.config.toml, set the base URL for your preferred provider and add your API key. It should look something like this:

  # .codeshift.config.toml
  
  [settings]
  baseUrl="https://openrouter.ai/api/v1"
  apiKey="sk-or-v1-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
  outputFile="xxxxxxxxxxx"
  model=""
  tokenUsage=true
  stream=true
  

  • The following base URLs are supported. Others may be used but are not supported and may cause errors:
    • OpenAI: https://api.openai.com/v1
    • OpenRouter: https://openrouter.ai/api/v1
    • Groq: https://api.groq.com/openai/v1.
  • For a list of models for supported providers, see:
