SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The TypeScript LSP toolkit enables semantic code intelligence for TypeScript and JavaScript by leveraging the typescript-lsp plugin to understand types, interfaces, and symbol relationships.

Core Features & Use Cases

Semantic code intelligence: navigate to definitions, find all references, inspect types, and diagnose type errors across TS/JS projects.
Editor-augmented navigation: use LSP operations such as goToDefinition, findReferences, hover, and documentSymbol for precise code understanding.
Real-world scenario: debugging a complex type mismatch in a large codebase by tracing symbol usage across modules with LSP.

Quick Start

Enable the TypeScript LSP plugin in your project and start semantic navigation to explore types and references.

FAQPage Schema

How do I navigate to definitions and find references in a TypeScript project?▼

TypeScript code intelligence provides semantic navigation by leveraging a language server to resolve symbols. You can use goToDefinition and findReferences operations to trace symbol usage across modules in TS/JS projects.

What is semantic code intelligence for TypeScript and JavaScript?▼

Semantic code intelligence for TypeScript and JavaScript understands types, interfaces, and symbol relationships within a codebase. It leverages a language server to perform type checking and diagnostics across modules.

Can I diagnose type errors across modules using a TypeScript language server?▼

Yes, you can diagnose type errors across modules using a TypeScript language server. It inspects types and diagnoses mismatches by resolving symbols based on your tsconfig or jsconfig configuration.

Do I need a tsconfig or jsconfig file to use TypeScript LSP for type checking?▼

Yes, performing type checking and symbol resolution with TypeScript LSP requires a properly configured project with a tsconfig or jsconfig file. This configuration enables the language server to understand project boundaries.

How do I get hover and documentSymbol information for TypeScript code?▼

You get hover and documentSymbol information by enabling the typescript-lsp plugin in your project. These LSP operations provide precise type and symbol details directly from the language server.

Why does TypeScript LSP require a properly configured project environment?▼

TypeScript LSP requires a properly configured project environment because the language server needs tsconfig or jsconfig boundaries to accurately resolve symbols and diagnose type errors across your codebase.
