#Examples

RPC proxy is distributed with a few examples of the most common end user usages.

There are not many prerequisites required to run examples, but you'll need the following:

• Node.js
• Node Package Manager
• Node packages, install it with npm install
• Other (example dependent)

This sample shows usage of bloom filters and how filter should be correctly created. Example can be started with: node generateBlom.js

This example needs more attention. Additional requirements is working RPC instance. For make everything work you need to set up env variables. There are a few solutions:

• use official Phore one:

  • PHORED_HOST="https://rpc.phore.io/rpc"
  • PHORED_RPC_PATH="/rpc"
  • PHORED_RPC_PORT=443

• use own local instance / docker instance.

Note: in some cases it could be necessary to set up also RPC_USER and RPC_PASS

This sample needs Socket.io server to be running. For make this work you need to set up env variables.

• WEB_HOST - ws server host e.g 'http://127.0.0.1'
• WEB_PORT - ws server path e.g 80 for http

You can run it with:

node subscribe.js address [address]

First address is subscribed by 'subscribeAddress', and all addresses are subscribed by bloom filter. This script use generateBloom.js to generate bloom filter.

For debug purposes you can send to 'blocknotify' Redis canal information about new block and it will propagate by the Redis through web socket server to your subscribe.js instance. Block hash must be valid and exist in Phore blockchain.
