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. Only CommonJS modules are supported by Function Compute in Node.js 16 and earlier.

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

• Specify type as module in the package.json file of a function to specify an ECMAScript module for all .js files.

• Use the .mjs file name extension to enable the system to treat all .mjs files as ECMAScript modules and .js files as CommonJS modules. You can use the .mjs extension for some files and the .js extension for other files based on your business requirements. .mjs files are always treated as ECMAScript modules and .js files are always treated as CommonJS modules.

Built-in modules

In addition to standard modules of Node.js, Function Compute provides commonly used modules for Node.js for your convenient reference. The following table lists the common modules that are provided by Function Compute.
