What files are in the installed nodejs folder?

Node.js is a running environment for JavaScript development that can run JavaScript scripts on the server side. When installing Node.js, a folder will be generated on the computer, which contains many files. Let me introduce to you the specific files in the Node.js folder.

1. node.exe

node.exe is the executable file of Node.js. Double-click it to open it to start the command line environment of Node.js (you can also use the command Enter the node command in the prompt window).

2. npm.exe

npm.exe is the package manager of Node.js, which can help us install, upgrade, and uninstall various Node.js modules. The npm command is followed by the name of the module to be installed, for example: npm install express.

3. node_modules

This is the module directory of Node.js. It contains various modules installed by Node.js or third-party modules that we install manually. When we reference a module in the application, Node.js will search whether the module exists in the directory, and if it exists, load it directly.

4. package.json

package.json is the description file of the Node.js application. It records various information of the application, such as name, version, dependencies Modules and so on. When we create a new Node.js application, an initial package.json file will be generated in this directory, which can be modified to manage the application.

5. package-lock.json

package-lock.json is a file generated during npm install and is used to record all modules in the currently installed node_modules folder. Version number information ensures that the same module version can be accurately installed on other machines or teamwork.

6. README.md

README.md is the description document of the application. It usually contains the application's usage instructions, developer information, update logs and other information. README.md is a text file based on Markdown format and can be edited using various Markdown syntaxes.

7. LICENSE

LICENSE is the license of the application, which is used to describe the copyright, authorization, usage restrictions, etc. of the application. In open source projects, licenses are very important to ensure the legality and sustainability of the project.

8. CHANGELOG.md

CHANGELOG.md is the change log of the application, which is used to record the changes that have occurred between each version of the application relative to the previous version. Including new features, bug fixes, updated documentation, etc. CHANGELOG.md is also a file based on Markdown format, which can be recorded clearly.

In addition to some of the files listed above, the Node.js folder also contains some binary files, configuration files, sample programs, etc. The functions of these files will vary depending on the specific application scenarios. When developing Node.js applications, being familiar with the roles and functions of these files will help improve our development efficiency and code quality.
