RubyGems:

No Rails required for the gem itself.

3. Env
Load
.env
in
config/boot.rb
(Rails) or at process start (plain Ruby).
SVEDA_CLIENT_BASE_URL=http://127.0.0.1:8787
SVEDA_CLIENT_HOST_API_KEY=replace-meSVEDA_CLIENT_BASE_URL=http://127.0.0.1:8787 SVEDA_CLIENT_HOST_API_KEY=replace-me
4. Plain Ruby
Empty base URL or key raises
Sveda::ConfigurationError.
Any Rack app can JSON-encode the hash.
Pass optional
policy
on mint when mapping roles to a named document —
embed policies.
session = Sveda::Client.start_host_session(
base_url: ENV.fetch("SVEDA_CLIENT_BASE_URL"),
host_api_key: ENV.fetch("SVEDA_CLIENT_HOST_API_KEY"),
visitor_id: "ruby-host"
)session = Sveda::Client.start_host_session(
base_url: ENV.fetch("SVEDA_CLIENT_BASE_URL"),
host_api_key: ENV.fetch("SVEDA_CLIENT_HOST_API_KEY"),
visitor_id: "ruby-host"
) 5. Rails
Keep
csrf_meta_tags
in the layout so
sveda-host.js
can send
X-CSRF-TOKEN.
Hide buttons unless
SVEDA_CLIENT_BASE_URL
is set.
