Managing notifications

In this exemple, you can get invited to Julius Caesar book release party. You may be 2000 years late, but cool people never show up on time anyway.

Discovering a resource's inbox

To find out where to reach any resource, all you have to do is ask! Inboxes are announced using the LDP term ldp:inbox in resources' RDF representation.

What is Cleopatra's inbox

const axios = require("axios")
const {fetch_inbox} = require("./discover-inbox")
// You can change that to your own webid
const resource_iri = "https://cleopatra.solid.community/profile/card#me"
// First, let's see the plain RDF representation of the resource
axios.get(resource_iri)
.then(response => {
  // Let us just display the content of the resource
  console.log(response.data);
  console.log("\n --- \n");
  // And now, let's just filter for its inbox
  fetch_inbox(resource_iri)
  .then(inbox => {
      console.log("The inbox of "+resource_iri+" is "+inbox)
  })
  .catch(error => {
    console.log(error);
  })})
.catch(error => {
  console.log(error);
})

Sending a notification

In the following snippet, after discovering the target's inbox, an invite is sent. Want to weasle your way in the coolest party of the Roman empire ? Just change the calendar_iri to your own!

Let's get crazy sending out invites

const axios = require("axios")
const $rdf = require("rdflib")
const {invite} = require("./invite")
const {fetch_inbox} = require("./discover-inbox")
const timeout = 3000
const LDP = $rdf.Namespace("http://www.w3.org/ns/ldp#")
// Let's assume that we know the IRI of the invitee's calendar
const calendar_iri = "https://cleopatra.solid.community/public/calendar/"
const store  = $rdf.graph();
const fetcher = new $rdf.Fetcher(store, timeout)
// First, fetch the inbox...
fetch_inbox(calendar_iri)
.then(inbox => {
  // ...and thenr perform a POST to the target inbox to send
  // the invite defined in invite.js
  axios({
      method: 'post',
      url: inbox,
      data: invite,
      headers: {
          "Content-type": "text/turtle",
          "Slug": "We gonna parteyy"
      }
  }).then (response => {
      console.log(response.status)
  }).catch(error => {
      console.log(error)
  });
}).catch(error => {
  console.log(error)
})
