Struct NpmEcosystem 

pub struct NpmEcosystem { /* private fields */ }

npm ecosystem implementation.

Provides LSP functionality for package.json files, including:

• Dependency parsing with position tracking
• Version information from npm registry
• Inlay hints for latest versions
• Hover tooltips with package metadata
• Code actions for version updates
• Diagnostics for unknown/deprecated packages

Implementations

impl NpmEcosystem

pub fn new(cache: Arc<HttpCache>) -> NpmEcosystem

Creates a new npm ecosystem with the given HTTP cache.
