Javascript Module - Dependency Graph

About

This page is about the dependency graph between module.

Build

The dependency graph is build from a single module (called the entry point)

• for a ESM module with the import statement
• for a commonJs module (node default) with the require statement

The dependency module files are found (resolved) by the resolver that try to find the file first:

• in the actual project
• then in the package dependency

Usage

Dependency graph are used in build operation that depends on it such as:

• tree-shaking - dead code elimination (tree is a short name for dependency tree (ie dependency graph)
• code splitting
• linting (quality check)
