npm

• remove all npm

  npm uninstall `ls -1 node_modules | tr '/\n' ' '`

  How do you uninstall all dependencies listed in package.json (NPM)?

• "dependencies" vs "devDependencies" 我總算比較搞懂一點他們的差異點。

  • dependencies

    mod-a
      dependents:
        - mod-b
    
    mod-c:
      dependents:
        - mod-a
    
    ----
    
    npm install mod-c
    
    installed modules:
      - mod-a
      - mod-b
      - mod-c
    

  • Dev Dependencies

    mod-a
      dev-dependents:
        - mod-b
      dependents:
        - mod-c
    
    mod-d
      dev-dependents:
        - mod-e
      dependents:
        - mod-a
    
    my-package
      dev-dependents:
        - mod-f
      dependents:
        - mod-d
    ----
    
    npm install mod-d
    
    installed modules:
      - mod-d
      - mod-a
      - mod-c
    
    ----
    
    checkout the mod-d code repository
    
    npm install
    
    installed modules: (安裝my-package結構如下)
      - mod-d
        - mod-a
          - mod-c
      - mod-f
