ES6 Modules: Should I Export Static Methods Individually or as a Module Object?

ES6 Modules: Exporting Static Methods and Individual Methods

Exporting

When exporting multiple static methods, it's recommended to use a dedicated module object rather than wrap them in a class. This approach eliminates the unnecessary class structure:

// myMethods.js
export default {
  myMethod1: () => {...},
  myMethod2: (...) => {...}
};

Importing

For importing multiple methods, explicitly listing each method in the import statement is preferred:

import {myMethod1, myMethod2} from 'myMethods';

However, the "import *" syntax is valid and can be useful if you intend to use most or all of the exports:

import * as myMethods from 'myMethods';
myMethods.myMethod1();

Performance Implications

There are minimal performance differences between the two approaches. Modern ES6 implementations optimize static identifiers well, making named exports efficient. Partial imports can also improve optimization speed by excluding unused exports. In most cases, maintainability considerations should guide the choice rather than performance.
