Creating a Dependency

You are advised to create function dependencies in EulerOS. If other OSs are used, an error may occur due to underlying dependent libraries. For example, the dynamic link library cannot be found.

  • If the modules to be installed need dependencies such as .dll, .so, and .a, archive them to a .zip package.

Creating a Dependency for a Node.js Function

Ensure that the corresponding Node.js version has been installed in the environment.

To install the MySQL dependency for a Node.js 8.10 function, run the following command:

npm install mysql --save

The node_modules folder is generated under the current directory.

  • Linux OS

    Run the following command to generate a ZIP package.

    zip -rq mysql-node8.10.zip node_modules

    The required dependency is generated.

  • Windows OS

    Compress node_modules into a ZIP file.

To install multiple dependencies, create a package.json file first. For example, enter the following content into the package.json file and then run the following command:

{
	"name": "test",
	"version": "1.0.0",
	"dependencies": {
		"redis": "~2.8.0",
		"mysql": "~2.17.1"
	}
}
npm install --save

Do not run the CNPM command to generate Node.js dependencies.

Compress node_modules into a ZIP package. This generates a dependency that contains both MySQL and Redis.

For other Node.js versions, you can create dependencies in the way stated above.
