@brechtvdv/actor-init-ldes-client

Fetches fragments of a TREE Event Stream and emits its data (in the future: members) when a fragment's caching headers has been invalidated In order to avoid receiving duplicate members, we will create in the future a tool filters members by storing it.

Install

npm install -g @brechtvdv/actor-init-ldes-client

In order to use it as a library, you can leave out the -g.

How to use it

Usage from the command line

actor-init-ldes-client --pollingInterval 10000 https://lodi.ilabt.imec.be/coghent/industriemuseum/objecten

Usage within application

The easyest way to create an engine (with default config) is as follows:

const newEngine = require('@brechtvdv/actor-init-ldes-client').default;

const LDESClient =  newEngine();

With the engine or client created, you can now use it to call te async createReadStream(url, options) method. Here is an example synchronizing with a TREE root node of an Event Stream with polling interval of 5 seconds:

  try {
    let url = "https://lodi.ilabt.imec.be/coghent/industriemuseum/objecten";
    let options = {
      "pollingInterval": 5000 // millis
    };
    let eventstreamSync = LDESClient.createReadStream(url, options);
    eventstreamSync.on('data', (data) => {
      console.log(data)
    });
    eventstreamSync.on('end', () => {
      console.log("No more data!")
    });
  } catch (e) {
    console.error(e);
  }
