Module module_map 

Module map and module graph.

Terms

• Module graph: it maintains the relationships between a module and its dependencies tree.
• Module map: it maintains all the dependencies loaded into the js rutime, i.e. the rsvim editor.

Module

In the most popular js runtime node.js, a module is loaded by the keyword require (Common JS) or import (ECMAScript Module). And there’re two kinds of imports: static and dynamic. For example:

Case-1: Static Import

// ES Module
const _ = import "lodash";

// Common JS
const _ = require("lodash");

// Case-2: Dynamic Import

// Wait for import complete.
const _ = await import("lodash");

// Trigger callbacks on import complete.
import("lodash")
  .then((_) => {})
  .catch((err) => {});

Static import runs synchronizely, dynamic import runs asynchronizely.
