@parcel/graph

What is @parcel/graph?

@parcel/graph is a utility package for creating and managing graphs, which are data structures consisting of nodes and edges. It is particularly useful for dependency management, task scheduling, and other scenarios where relationships between entities need to be represented and traversed.

What are @parcel/graph's main functionalities?

Creating a Graph

This feature allows you to create a new graph instance. The graph can then be populated with nodes and edges.

const { Graph } = require('@parcel/graph');
const graph = new Graph();
console.log(graph);

Adding Nodes

This feature allows you to add nodes to the graph. Nodes are the entities or points in the graph.

const { Graph } = require('@parcel/graph');
const graph = new Graph();
graph.addNode('A');
graph.addNode('B');
console.log(graph.nodes);

Adding Edges

This feature allows you to add edges between nodes in the graph. Edges represent the relationships or connections between nodes.

const { Graph } = require('@parcel/graph');
const graph = new Graph();
graph.addNode('A');
graph.addNode('B');
graph.addEdge('A', 'B');
console.log(graph.edges);

Traversing the Graph

This feature allows you to traverse the graph starting from a specific node. Traversal can be used to explore the graph and find paths or dependencies.

const { Graph } = require('@parcel/graph');
const graph = new Graph();
graph.addNode('A');
graph.addNode('B');
graph.addEdge('A', 'B');
const traversal = graph.traverse('A');
console.log(traversal);

Other packages similar to @parcel/graph

graphlib

Graphlib is a library for creating and manipulating directed graphs in JavaScript. It provides similar functionalities to @parcel/graph, such as adding nodes and edges, and traversing the graph. However, it is more focused on general-purpose graph manipulation rather than being integrated into a build tool like Parcel.

cytoscape

Cytoscape is a graph theory library for visualizing and analyzing graphs. It offers a wide range of features for graph manipulation and visualization, making it more suitable for applications that require interactive graph displays. Compared to @parcel/graph, Cytoscape is more feature-rich in terms of visualization capabilities.

d3-graphviz

D3-graphviz is a library that integrates Graphviz with D3.js to create and manipulate graphs. It is particularly useful for visualizing complex graphs and provides extensive customization options. While @parcel/graph focuses on graph data structures and traversal, d3-graphviz excels in rendering and visualizing graphs.
