Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@rdfjs/parser-n3

build status npm version

N3 parser which implements the RDF/JS Sink interface using the N3.js library.

Usage

The package exports the parser as a class, so an instance must be created before it can be used. The .import method, as defined in the RDFJS specification, must be called to do the actual parsing. It expects a Turtle, Trig, N-Triples or N-Quads string stream. The method will return a stream which emits the parsed quads. It also emits prefix events as defined in the RDF/JS specification.

The constructor accepts an options object with the following optional keys:

  • baseIRI: Allows passing the base IRI manually to the N3.js library.
  • factory: Use an alternative RDF/JS data factory. By default the reference implementation is used.

It's also possible to pass options as second argument to the .import method. The options from the constructor and the .import method will be merged together.

Example

This example shows how to create a parser instance and how to feed it with a stream from a string. The parsed quads and the prefixes are written to the console.

import ParserN3 from '@rdfjs/parser-n3'
import { Readable } from 'readable-stream'

const parserN3 = new ParserN3()

const input = Readable.from(`
PREFIX s: <http://schema.org/>

[] a s:Person ;
  s:jobTitle "Professor" ;
  s:name "Jane Doe" ;
  s:telephone "(425) 123-4567" ;
  s:url <http://www.janedoe.com> .
`)

const output = parserN3.import(input)

output.on('data', quad => {
  console.log(`quad: ${quad.subject.value} - ${quad.predicate.value} - ${quad.object.value}`)
})

output.on('prefix', (prefix, ns) => {
  console.log(`prefix: ${prefix} ${ns.value}`)
})
