FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package graph-core
nexus-scholar/graph-core
graph-core is a lightweight PHP graph data-structure package for directed and undirected graphs. It provides node and edge attributes, efficient adjacency lookups, subgraph views, and exporters for common graph-visualization formats.
Role In Nexus Scholar
This package is the graph foundation for Nexus Scholar citation-network work. It intentionally stays generic: scholarly concepts such as papers, citations, co-citation, bibliographic coupling, screening, and exports live in nexus-scholar/core, while graph storage, traversal primitives, attributes, and serialization live here.
Use it directly for PHP graph modeling, or pair it with nexus-scholar/graph-algorithms when you need centrality, pathfinding, traversal, components, ordering, or minimum-spanning-tree algorithms.
Features
- Directed and undirected graph support.
- Node and edge attributes.
- Integer indexing internally for fast adjacency lookups.
- Read-only subgraph views without copying the full graph.
- Cytoscape.js JSON, GraphML, and GEXF exporters.
- PHP 8.2+ types and interfaces.
- No runtime dependencies except
ext-domfor XML export formats. - Pest-backed test suite.
Requirements
- PHP 8.2+
