Direct-to-S3 uploads in a Node.js application running on Heroku
Simple example demonstrating how to accomplish a direct upload to Amazon's S3 in a Node.js web application.
This example uses the express web framework to facilitate request-handling. However, the process of signing the S3 PUT request would be identical in most Node apps.
This code is mostly ready to be run as cloned, but a function will need to be properly defined to handle the storing of the POSTed information. The current example simply demonstrates the upload to S3.
Dependencies and Installation
Ensure Node is installed. This can be done through your package manager or from their website.
Clone this repository:
$ git clone https://github.com/flyingsparx/NodeDirectUploader.git
Change directory into the application and use
npm to install the application's dependencies:
$ cd NodeDirectUploader $ npm install
Running the application
- Set environment variables for your AWS access key, secret, and bucket name (see companion article)
- Visit localhost:3000/account to try it out
Deploying the application
See the article Deploying with Git for more detailed information on deploying to Heroku.
- Download and install the Heroku toolbelt
- Commit your application to a local Git repository (e.g.
git add .,
git commit -m "version 1 commit", etc.)
- Create the application on Heroku by adding a Git remote (
$ heroku create)
- Push your code to the new Heroku repo (
$ git push heroku master)
