AWS s3 upload, list and delete recipe for clojure web apps.
Small server-side wrapper for amazonica and s3-beam for uploading, listing and deleting files from your clojure(script) web app. The main reason to use both s3-beam and amazonica in the same implementation is to leverage s3-beam to perform direct from browser uploading of files to s3 (therefore saving any server-side handling of those files) and to leverage amazonica for everything else (and again, not have to do any server-side handling of the actual files).
Note: This is a bare bones recipe and the amazonica library has much more functionality than what's demonstrated here.
Requires:
Wherever you define your routes, add a path for "/sign" like so:
(defroutes
;; aws s3-beam
(GET "/sign" {params :params} (aws-s3/s3-sign))
;; end aws s3-beam
)
List objects like so:
(ns server.some.namespace
(:require
[server.controllers.aws.s3 :as aws-s3]))
(aws-s3/list-objects)
Delete an object like so:
(ns server.some.namespace
(:require
[server.controllers.aws.s3 :as aws-s3]))
(aws-s3/delete-object-by-url! url)
;; OR
(aws-s3/delete-object-by-key! key)
Upload an object like so (where uploaded
is a core.async channel):
(ns client.some.namespace
(:require
[s3-beam.client :as s3]))
(s3/s3-pipe uploaded)
For more info on how to use channels with s3-beam, see the s3-beam documentation: https://github.com/martinklepsch/s3-beam#3-integrate-the-upload-pipeline-into-your-frontend
