Function Compute:Environment overview

Node.js runtimes

The following table lists the Node.js runtimes that Function Compute supports.

Specify a handler as an ES module

Function Compute supports ECMAScript (ES) modules in the Node.js 18 runtime and later. In earlier runtimes, such as Node.js 16 and older, Function Compute supports only CommonJS modules.

You can specify your code as an ES module in one of two ways.

• Set the type field in the function's package.json file to module. This specifies all .js files as ES modules.

• Use the .mjs file name extension. This treats files with the .mjs extension as ES modules and files with the .js extension as CommonJS modules. You can mix both module types in your function using the appropriate file extensions.

Built-in Node.js modules

In addition to the standard modules of Node.js, the Function Compute Node.js runtime environment includes several common modules that you can directly reference. Function Compute provides the following common modules:
