Implementation Reference
- lib/npm-service.js:116-135 (helper)The getVersionComparison() helper method on NpmService that performs the actual npm registry lookup and comparison logic, returning packageName, currentVersion, latestVersion, isLatest, distTags, needsUpdate, availableVersionsCount, releaseDate, and currentVersionReleaseDate.
async getVersionComparison(packageName, currentVersion) { const packageInfo = await this.getPackageInfo(packageName); const latestVersion = packageInfo['dist-tags']?.latest; const distTags = packageInfo['dist-tags'] || {}; const isLatest = currentVersion === latestVersion; const availableVersions = Object.keys(packageInfo.versions || {}); return { packageName, currentVersion, latestVersion, isLatest, distTags, needsUpdate: !isLatest, availableVersionsCount: availableVersions.length, releaseDate: packageInfo.time?.[latestVersion] || null, currentVersionReleaseDate: packageInfo.time?.[currentVersion] || null, }; }
