How to choose nodejs installation mode

Node.js has three installation modes: global installation, local installation and nvm. The best pattern depends on the project type, environment constraints, version management, and isolation requirements. Global installation works for shared modules, local installation isolates project dependencies, and nvm manages multiple Node.js versions.

Node.js installation mode

Node.js provides a variety of installation modes to meet different needs and environment. The following introduces the main installation modes and guides you to choose the mode that suits you best.

1. Global installation

• Advantages:

  • allowed to be used npm Install and run modules from anywhere.
  • Easy to install and uninstall.

• Disadvantages:

  • May conflict with local installation.
  • Environment that affects all projects.

2. Local installation

• Advantages:

  • Isolate each project's Node.js version and dependencies.
  • Avoid conflicts with global installation.

• Disadvantages:

  • Requires Node.js to be installed in each project.
  • May need to deal with version differences.

3. nvm (Node Version Manager)

• Advantages:

  • Manage multiple Node.js versions.
  • Easily switch Node.js versions between projects.

• Disadvantages:

  • May require additional configuration.
  • May be incompatible with some systems or environments.

Choose the best mode

You should choose the best Node.js installation mode based on the following factors:

• Project type: Local installation is suitable for independent projects, while global installation is suitable for situations where modules need to be shared across projects.
• Environmental limitations: nvm requires specific permissions and configuration and may not be suitable for all systems.
• Version management: If you need to manage multiple Node.js versions, nvm is a good choice.
• Isolation requirements: If you need to isolate each project's dependencies, then a local installation is essential.

In general:

• If you need to share modules across projects and no version management is involved, Install globally is a good choice.
• If you need to isolate project dependencies and manage Node.js versions, Local installation plus nvm is the recommended combination.
