amdjs-api VS umd

AMD (Asynchronous Module Definition), is a pattern to define and consume module. It is implemented by RequireJS library. AMD provides a define function to define module, which accepts the module name, dependent modules’ names, and a factory function:

AMD, which was introduced in 2010, uses define/require and loads modules asynchronously. RequireJS is the popular choice for using the AMD syntax in the browser.

A module format is the syntax we use to define a module. Different module formats such AMD, CommonJS, UMD and System.register have emerged in the past and a native module format is now available since ES6.

Check out this fascinating GitHub project for more examples of UMD formats.

UMD (Universal Module Definition) is a set of tricky patterns to make your code file work in multiple environments.

Exports in a umd format so the library works everywhere.

Supports circular references

To make UMD build available on both browsers and Node.js, set globalObject option to 'this'.

A modular system that your compiled application will use. You can choose: None, CommonJS, AMD, System, UMD, ES6, ES2015, ES2020 or ESNext. For backend apps/packages ES6 or CommonJS is suitable depending on Node.js version you want to support. For frontend apps ES6 is also suitable. And for support of older browsers and isomorphic applications, UMD is definitely worth choosing.
