## What it is
TypeWiz is a TypeScript tool that monitors variable types at runtime and automatically inserts missing type annotations into your source code. It ships as a core library plus integrations for Node.js, Webpack, and the CLI.

## Use cases
- add missing type annotations to typescript code automatically
- infer typescript types from runtime values
- gradually type an untyped javascript codebase
- instrument node.js code to discover parameter types
- improve type safety of legacy typescript projects

## When to choose
- you have an untyped or partially typed TypeScript codebase and want automated type annotation
- you want runtime-inferred types written back into source
- you need a webpack or node runner integration for type discovery

## When to avoid
- you need an actively maintained tool - the project is deprecated as of 2021
- you want static type inference without running the code
- your project uses very recent TypeScript versions that may be incompatible

## Facets
- artifact type: library
- maturity: abandoned
- function: type-system, developer-tools, build-tool
- domain: developer-tools, programming-languages, web-development
- platform: cli, cross-platform
- tags: typescript, type-inference, code-automation, webpack-plugin, deprecated, nodejs
