# graphy.js 🍌
`graphy` is a collection of *high-performance* RDF libraries for JavaScript developers with a focus on usability. API works in both the browser and Node.js. Expressive CLI tool also available for Node.js.

[https://graphy.link/](https://graphy.link/)

## Performance Benchmarks
🚀 [See how well `graphy` outperforms all others](https://github.com/blake-regalia/graphy.js/blob/master/perf/README.md).

## Command Line Interface
📑 [See documentation for CLI here](https://graphy.link/cli).

### Install the `graphy` bin CLI
 - npm:
   ```console
   $ npm install --global graphy
   $ graphy --help
   ```

- yarn:
   ```console
   $ yarn global add graphy
   $ graphy --help
   ```

## [Features](https://graphy.link/)
 - [Read RDF documents](https://graphy.link/content.textual#verb_read) using streams. Includes support for N-Triples (.nt), N-Quads (.nq), Turtle (.ttl), and TriG (.trig).
 - [Write RDF data](https://graphy.link/content.textual#verb_write) using streaming transforms with the awesome and intuitive [concise triples and concise quads language](https://graphy.link/concise).
 - [Construct RDF data](https://graphy.link/concise#hash_c3) using ES object literals that reflect the tree-like structure of quads, `graph -> subject -> predicate -> object`, including nested blank nodes and RDF collections.
 - [Compute the union, intersection, difference or subtraction](https://graphy.link/memory.dataset.fast) between multiple RDF graphs analagous to [Set Algebra](https://en.wikipedia.org/wiki/Algebra_of_sets).
 - [Compare two RDF graphs](https://graphy.link/memory.dataset.fast#method_canonicalize) for isomoprhic equivalence, containment, and disjointness by first canonicalizing them with the [RDF Dataset Normalization Algorithm](https://json-ld.github.io/normalization/spec/).
 - [Transform RDF data from the command-line](https://graphy.link/cli) by piping them through a series of sub-commands.
 - [Scan RDF documents](https://graphy.link/content.textual#verb_scan) and run custom code using multiple threads for maximum throughput.
