pg-next

A simple lib with what is needed to connect with jdbc.next to postgresql.

Already including types for jsonb using cheshire and timestamp with timezone using instant from clojure.java-time.

Usage

Import from clojars:

It will pull next.jdbc, postgres jdbc driver, hikari cp and all other deps for you.

Require the lib:

(require '[pg-next.core :refer [make-pool]])

Create a connection pool. These are the default values, you only need to supply what you want to override.

(def db-spec 
 {:host "localhost"
    :port "5432"
    :username "postgres"
    :password "postgres"
    :dbname "postgres"})

(def pool (make-pool db-spec))

Use the pool with next.jdbc:

(require '[next.jdbc :as jdbc])
(require '[next.jdbc.sql :as sql])
(require '[java.time :refer [instant]])

(jdbc/execute-one! pool
["CREATE TABLE IF NOT EXISTS my_table (
id varchar primary key,
my_timestamp TIMESTAMP WITH TIME ZONE,
my_object JSONB
)"])

(sql/insert! pool :my_table {:id "m1" :my_timestamp (instant) :my_object {:foo "bar"}})

(sql/get-by-id pool :my_table "m1")
#=>:my_table{:id "m1" :my_timestamp #java.time.Instant :my_object {:foo "bar"}}
