FlatironS3Uploader

A tool for resizing and uploading images to AWS S3.

Installation

$ gem install flatiron-s3-uploader

Configuration

The S3 upload functionality requires that you have the following environment variables set:

• ENV['AWS_ACCESS_KEY_ID']
• ENV['AWS_SECRET_ACCESS_KEY']
• ENV['AWS_REGION']

Usage

The core functionality of uploading (and optionally resizing) images can be performed one of two ways. To use this Ruby gem in other Ruby projects, use the FlatironS3Uploader.upload method directly:

# Upload a file to a specified S3 bucket
FlatironS3Uploader.upload('path/to/image.png', 'bucket-name')
# => "https://bucket-name.s3.amazonaws.com/image.png"

# Upload and resize an image
FlatironS3Uploader.upload('path/to/image.png', 'bucket-name', { width: 400, directory: 'folder/subfolder' })
# => "https://bucket-name.s3.amazonaws.com/folder/subfolder/image.png"

The FlatironS3Uploader.upload(path, bucket, options = {}) method takes the following parameters:

• path: The file location of the image to be uploaded.
• bucket: The name of the S3 bucket.
• options:
  • width: The width of the resized image. If a +height+ is not specified, the height will scale based on the specified width.
  • height: The height of the resized image. If a +width+ is not specified, the width will scale based on the specified height.
  • directory: The directory of the S3 bucket to upload to (i.e. 'phase-3/lab-name')

You can also use the gem directly from the command line:

$ flatiron-s3-uploader upload path/to/image.png --bucket bucket-name --width 400 --directory folder/subfolder

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bundle exec rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

This project uses Rubocop to enforce consistent styling via a pre-commit hook, so any time you make a commit, your code will be linted. For VSCode users, it's suggested that you install the Ruby VSCode extension and enable linting in VSCode via the settings.json file so that you can see linting errors before committing your code:

{
  "ruby.lint": {
    "rubocop": {
      "useBundler": true
    }
  },
  "ruby.format": "rubocop"
}

You can also run Rubocop manually to get a list of any issues:

$ bundle exec rubocop
