Developers often struggle with choosing the right npm command for CI/CD pipelines, so this guide compares npm install and npm ci, explains version specifiers, and details how --legacy-peer-deps and --force can resolve dependency conflicts, registry issues, and build failures.
This article explains how npm installs dependencies, the role of package‑lock.json, the evolution from nested to flat node_modules structures, npm's caching strategy, and provides practical guidance for setting up a private npm registry and handling common installation issues.
This article examines the development of npm, describing its early nested dependency model in v1/v2, the flat‑dependency approach introduced in v3, and the package‑lock enhancements of v5, while highlighting the advantages and new challenges each version brought to Node.js package management.
npm 5 introduces automatic package‑lock generation, default --save, enhanced Git and file‑dependency handling, new prepack/postpack scripts, stronger integrity checks, a fully managed cache and registry tweaks, while narrowing Yarn’s speed advantage despite early bugs, making it a compelling alternative for npm‑centric workflows.
