Setting up a Node.js Development Environment
This guide covers the professional way to set up a Node.js environment on Linux using Node Version Manager (nvm). Using nvm allows you to install multiple versions of Node.js and switch between them effortlessly, which is essential for working on different projects with different requirements.
1. Prerequisites
The nvm installation script requires curl or wget to download. Ensure you have these installed by following the initial post-install configuration.
- Reference: Post-Install Linux Configuration
2. Install Node Version Manager (nvm)
-
Open your terminal.
-
Run the official installation script. This command downloads and executes the script from the
nvmGitHub repository.curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash(Note: Always check the official nvm repository for the latest version number and command).
-
Reload your shell for the changes to take effect. You can either close and reopen your terminal or run:
source ~/.bashrc -
Verify installation:
command -v nvmIf this command outputs
nvm, the installation was successful.
3. Install Node.js
With nvm installed, you can now install Node.js. It's best practice to start with the latest Long-Term Support (LTS) version.
nvm install --ltsnvm will download, compile, and install the latest stable LTS release of Node.js and set it as your default.
4. Verification
Check that node and its package manager, npm, are ready to use.
node -v
npm -vThese commands should return the version numbers of the installed software (e.g., v20.11.0 and 10.2.4).
5. Managing Multiple Versions
The power of nvm comes from managing different project needs.
- Install a specific version:
nvm install 18.19.0 - List all installed versions:
nvm ls - Switch to another version for your current session:
nvm use 18.19.0 - Set a default version for all new shells:
nvm alias default 20.11.0
