A Clojure library designed to read a stream of changes from the npm registry.

[open-services/npm-registry-follow "1.2.1"]

open-services/npm-registry-follow {:mvn/version "1.2.1"}

user=> (def stop (npm-registry-follow.core/listen-for-changes #(println %)))
#'user/stop
"chung-rn"
"flycomponents"
"react"
...
user=> (stop)
;; No longer following changes

;; Alternative to wait for stream to properly close
user=> @(stop)

;; Or, using polling
user=> (def interval (* 1000 3)) ;; three seconds
#'user/interval
user=> (def stop (npm-registry-follow.core/poll-for-changes interval #(println %)))
#'user/stop
"chung-rn"
"flycomponents"
"react"
...
user=> (stop)
;; No longer doing any polling

;; If there is a exception when fetching updates, a map with `:error? true` and
;; `:exception` set to the exception that happened.
;; Make sure to check for this in your code, as otherwise silent errors can happen

;; If you want to follow a different registry than `replicate.npmjs.com`, you
;; can rebind `*registry-url*` with `binding`
