Stackwise

Generates complete Node.js function implementations directly within VSCode editor by accepting natural language descriptions and converting them into syntactically valid, executable code. Integrates with VSCode's editor API to insert generated code at cursor position, maintaining indentation and formatting context from the surrounding file. Uses LLM-based code generation with language model inference to produce functions matching the semantic intent of user descriptions.

Inserts generated Node.js code at the current cursor position while automatically detecting and matching the indentation level of surrounding code. Uses VSCode's TextEditor API to read current indentation context, apply consistent formatting, and insert code blocks without breaking file structure. Handles both single-line and multi-line code insertion with proper line break handling.

Abstracts underlying LLM provider implementations (OpenAI, Anthropic, local models) behind a unified interface, allowing users to switch between different language models without changing extension code. Routes generation requests to configured provider endpoint with standardized prompt formatting and response parsing. Supports both cloud-based API calls and local model inference through compatible endpoints.

Parses natural language function descriptions to infer parameter names, types, and return types, then generates appropriate TypeScript/JavaScript function signatures before implementation. Uses pattern matching and LLM-based semantic analysis to extract function intent, identify required inputs, and determine output structure. Produces type-annotated signatures compatible with TypeScript strict mode.

Maintains a history of generated functions and allows users to request refinements or variations on previous generations without re-describing the entire function. Tracks generation context (description, parameters, previous output) and uses it to guide subsequent refinement requests. Enables iterative development where users can ask for performance improvements, additional features, or alternative implementations.

Generates Node.js functions with built-in error handling patterns, input validation, and try-catch blocks based on function signature and description. Automatically includes common validation checks (null checks, type validation) and error handling boilerplate appropriate to the function's purpose. Produces production-ready code with defensive programming patterns rather than minimal implementations.
