About

Currently lives here

Scrapes comments from Sootoday articles and displays like/dislike statistics for comments and users.

Prerequisites

You will need Leiningen 2.0 or above installed.

Datomic is used for storage, although you can use an in-mem instance for developing locally, you may still want to consider running an local instance. I personally it using Docker.

Running

To start a web server for the application, run:

lein repl

(salttoday.core/-main)

Then run figwheel to get live interactive programming, run:

lein figwheel

By default, SaltToday connects to a in-memory Datomic instance. If you wish to have your data persisted, you can run your instance of Datomic with:

docker run -d -p 4334-4336:4334-4336 --name datomic-free akiel/datomic-free

Then modify the :database-url in this file to datomic:free://localhost:4334/salttoday.

For more information on running Datomic in docker check out these docs.

Running Locally Against Local In-Mem Database

You can run queries and such in the REPL once it is spun up, This allows for rapid development of the backend. For Example:

(require '[datomic.api :as d])
(def conn salttoday.db.core/conn)
(def db (d/db conn))
(def query (salttoday.db.core/create-get-comments-query db nil nil nil 17592186045892))
(def results (apply (partial d/q (:query query)) (:args query)))
;(def results (salttoday.db.core/get-comments db 0 nil nil 17592186045650))

Datomic Usage on Server

It's also possible to use a repl in the server to query the live database:

(require '[datomic.api :as d])
(def conn (d/connect "datomic:free://localhost:4334/salttoday"))
(def db (d/db conn))
(def query (salttoday.db.core/create-get-comments-query db "Trudumb" nil))
(def results (apply (partial d/q (:query query)) (:args query)))
