Function Compute:Overview

Node.js runtimes

The following table lists the Node.js runtimes that are supported by Function Compute.

Specify an ECMAScript module as the handler

ECMAScript modules are supported by Function Compute in Node.js 18 and later. For Node.js 16 and earlier versions, Function Compute supports only CommonJS modules.

You can specify an ECMAScript module in one of the following methods:

• Specify type in the package.json file of a function as module. In this case, all .js files are specified as ECMAScript modules.

• Use the .mjs file name extension. In this case, .mjs files are regarded as ECMAScript modules, and .js files are still regarded as CommonJS modules. You can mix ECMAScript modules and CommonJS modules by using both the .mjs and .js file extensions. By default, .mjs files are treated as ECMAScript modules and .js files are treated as CommonJS modules.
