TypeScript Reader is a tool that helps you read TypeScript code together with a Large Language Model (LLM).
- Allows the LLM to explore functions without requiring manual reading
- Lets you backtrack through previously explored function paths
- Helps detect bugs in the currently investigated function path using the LLM
- Visualizes the function under investigation as a diagram
- Summarizes the explored function path into a report using the LLM
- Exports and imports the explored function path as JSON
- Enables you to navigate TypeScript code without aimless random walks
- Allows the LLM to summarize hundreds or thousands of lines of function code in under a minute—something that could take over 10 minutes without prior knowledge of the codebase
- Includes functionality for detecting bugs in TypeScript code
- Provides explanations of function paths and logic that would otherwise remain implicit knowledge
- Identifying the entry point of the codebase
- Choosing which functions to explore (LLM-driven auto-exploration is less accurate)
- It cannot analyze the entire codebase at once without splitting it into parts
- Install typescript-language-server
npm install -g typescript-language-server typescript
# or
brew install typescript-language-serverAfter that disable "TypeScript and JavaScript Language Features" to avoid conflicts of lsp

Show All Commands (Ctrl/Cmd + Shift + P) -> Type "Extensions: Show Built-in Extensions" -> Features -> TypeScript and JavaScript Language Features -> Disable (Workspace)
- Install VS Code
Please install version 1.100.0 or later of Visual Studio Code.
- Install TypeScript Reader
Download TypeScript-Reader at vscode store.
-
Open the Extension Once downloaded, open the Command Palette with Command + Shift + P, and click “Open TypeScript Reader Tab”. If a tab opens on the right side, it was successful.
-
Configure settings Provide the path to typescript-language-server and select your preferred LLM (OpenAI, Claude, or Plamo).
-
Start exploration in the chat UI
To begin, input the following:
- File path to start exploring
- Function to start from
- Purpose of the exploration
This will initiate the analysis process.
- Guide the Exploration
The LLM will suggest important functions within the current function. You then select which one to explore next. This process repeats as long as you like, allowing you to explore deeper step by step.
