Struct NpmLockParser 

pub struct NpmLockParser;

package-lock.json file parser.

Implements lock file parsing for npm package manager. Supports both project-level and workspace-level lock files.

Lock File Location

The parser searches for package-lock.json in the following order:

1. Same directory as package.json
2. Parent directories (up to 5 levels) for workspace root

Examples

use deps_npm::lockfile::NpmLockParser;
use deps_core::lockfile::LockFileProvider;
use tower_lsp_server::ls_types::Uri;

let parser = NpmLockParser;
let manifest_uri = Uri::from_file_path("/path/to/package.json").unwrap();

if let Some(lockfile_path) = parser.locate_lockfile(&manifest_uri) {
    let resolved = parser.parse_lockfile(&lockfile_path).await?;
    println!("Found {} resolved packages", resolved.len());
}

Trait Implementations

impl LockFileProvider for NpmLockParser

fn locate_lockfile(&self, manifest_uri: &Uri) -> Option<PathBuf>

Locates the lock file for a given manifest URI.

fn parse_lockfile<'life0, 'life1, 'async_trait>( &'life0 self, lockfile_path: &'life1 Path, ) -> Pin<Box<dyn Future<Output = Result<ResolvedPackages>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Parses a lock file and extracts resolved packages.

fn is_lockfile_stale( &self, lockfile_path: &Path, last_modified: SystemTime, ) -> bool

Checks if lock file has been modified since last parse.
