Learn How Easy It Can Be To Build Scalable Newsfeeds and Activity Streams

Stream has official clients for JS/Node, Ruby, Python, PHP, Go, Java and C#/.NET.

Setup

Let’s get set up! First, install the client as specified below:

# install directly with gem
gem install "stream-ruby"

# or add this to your Gemfile and then run bundler
gem "stream-ruby"

All source code can be found on GitHub.

To instantiate the client you need an API key and secret. You can find the key and secret on the dashboard. The examples below already include your key and secret.

# Instantiate a new client (server side)
require 'stream'
client = Stream::Client.new('{{ api_key }}', '{{ api_secret }}', :location => 'us-east')
# Find your API keys here https://getstream.io/dashboard/

If you want to use Stream on your mobile or web application, you need to generate a token server-side that the client can use to authenticate as a user of your application.

Generate User Token Server-Side

This code generates the token for one of your users; a common place to do this is at signup or login. The token is then passed to the frontend.

user_token = client.create_user_session_token('the-user-id')

Use Stream API client-side

const stream = require("getstream");

// Instantiate new client with a user token
const client = stream.connect(
  "{{ api_key }}",
  "{{ feed_token }}",
  "{{ app_id }}",
);

// OR

import stream from "getstream";

const client = stream.connect(
  "{{ api_key }}",
  "{{ feed_token }}",
  "{{ app_id }}",
);

More details about authentication can be found in the REST docs

Quick Start

The quick start below shows you how to build a scalable social network. It highlights the most common API calls:

chris = client.feed('user', 'chris')

# Add an Activity; message is a custom field - tip: you can add unlimited custom fields!
activity_data = { :actor => 'chris', :verb => 'add', :object => 'picture:10', :foreign_id => 'picture:10', :message => 'Beautiful bird!' }
chris.add_activity(activity_data);

# Create a following relationship between Jack's "timeline" feed and Chris' "user" feed:
jack = client.feed('timeline', 'jack')
jack.follow('user', 'chris')

# Read Jack's timeline and Chris' post appears in the feed:
activities = jack.get(:limit => 10)

# Remove an Activity by referencing it's foreign_id
chris.remove_activity('picture:10', foreign_id=true)

That was a good deal of information at once. The getting started docs provide a more detailed and interactive explanation.
