Templates

Breyta templates reference for reusable prompts, HTTP payloads, SQL, and notification channel definitions.

Quick Answer

Define reusable content in top-level :templates, then reference by :template and supply runtime :data.

Supported Template Types

Type	Primary use	Typical consumers
`:http-request`	Reusable HTTP request maps	`flow/step :http`
`:llm-prompt`	Reusable system/user prompt content	`flow/step :llm`
`:db-query`	Reusable SQL text and query shape	`flow/step :db`
`:notification`	Reusable notification channel payloads/config	`flow/step :wait` (`:notify`), `flow/step :notify`

Definition Shape

{:templates [{:id :welcome
              :type :llm-prompt
              :system "You are concise."
              :prompt "Welcome {{user.name}}"}
             {:id :approval-email
              :type :notification
              :channels {:http {:connection :sendgrid
                                :path "/v3/mail/send"
                                :method :post
                                :json {:subject "{{title}}"
                                       :content [{:type "text/plain"
                                                  :value "Approve: {{approval-url}}\nReject: {{rejection-url}}"}]}}}}]}

Usage Patterns

LLM prompt template:

(flow/step :llm :welcome-user
  {:connection :ai
   :template :welcome
   :data {:user {:name "Ada"}}})

HTTP request template:

(flow/step :http :create-order
  {:connection :orders-api
   :template :create-order
   :data {:customer-id "cus_123" :amount 4200}})

DB query template:

{:templates [{:id :recent-orders
              :type :db-query
              :sql "select * from orders where created_at >= {{from}}"}]}

Wait notification template:

(flow/step :wait :approval
  {:key "approval:123"
   :timeout "2h"
   :notify {:template :approval-email
            :data {:title "Order Approval"}}})
