trailpack-jsonld

📦 Add a Trails service to warp jsonld features

This package is an implementation of jsonld in Trails framework.

For the moment it's just a wrapper but in a short amount of time it will symplify the json-ld calls

Intallation

With yo :

npm install -g yo generator-trails
yo trails:trailpack trailpack-jsonld

With npm (you will have to create config file manually) :

npm install --save trailpack-jsonld

Configuration

Enable JsonLD

// config/main.js

  packs: [
    ...
    require('trailpack-jsonld')
  ],

Check that jsonld config is loaded on index.js

// config/index.js
...
exports.srcds = require('./jsonld')

Configure

// config/jsonld.js

module.exports = {

  dictionaries: [{
    name: "schema.org",
    url: "http://schema.org"
  }],

  defaultDictonary: "schema.org"
}

Usage

Quick Examples

let jsonldLegacyService = this.app.services.JsonldService.legacy()

var doc = {
  "http://schema.org/name": "Manu Sporny",
  "http://schema.org/url": {"@id": "http://manu.sporny.org/"},
  "http://schema.org/image": {"@id": "http://manu.sporny.org/images/manu.png"}
};
var context = {
  "name": "http://schema.org/name",
  "homepage": {"@id": "http://schema.org/url", "@type": "@id"},
  "image": {"@id": "http://schema.org/image", "@type": "@id"}
};

// compact a document according to a particular context
// see: http://json-ld.org/spec/latest/json-ld/#compacted-document-form

jsonldLegacyService.compact(doc, context, function(err, compacted) {
  console.log(JSON.stringify(compacted, null, 2));
  /* Output:
  {
    "@context": {...},
    "name": "Manu Sporny",
    "homepage": "http://manu.sporny.org/",
    "image": "http://manu.sporny.org/images/manu.png"
  }
