buffer-static-upload

A straightforward static asset uploader which versions files by their contents and generates a json file for your application to read the uploaded file locations from.

Versioned files and Images

.js and .css files are versioned during upload using a hash of the file's contents as to allow for cache-busting. You can skip the automatic versioning by using the -skip-versioning flag.

Images and other files are not versioned to allow for maximum caching and due to their contents not changing very often like .css and .js files do.

Install

A pre-compiled binary is available for download for both Linux and macOS. Replace the version (ex. 0.2.0) in the URL below for the version you require:

curl -L https://github.com/bufferapp/buffer-static-upload/releases/download/0.2.0/buffer-static-upload-`uname -s` > /usr/local/bin/buffer-static-upload
chmod +x /usr/local/bin/buffer-static-upload

Usage

Ensure your AWS credentials environment variables are set (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY). The cli has the following argument options:

$ buffer-static-upload -h
Usage of ./buffer-static-upload:
  -bucket string
    	the s3 bucket to upload to (default "static.buffer.com")
  -dir string
    	required, the directory to upload files to in the bucket
  -dry-run
    	print the output only, skip file uploads and manifest creation
  -files string
    	the path to the files you'd like to upload, ex. "public/**/.*js,public/style.css"
  -format string
    	format of the output [json,csv] (default "json")
  -o string
    	the filename for the versions manifest (default "staticAssets.json")
  -skip-versioning
    	skip versioning uploaded files
  -v	print the current buffer-static-upload version

For example, you can use glob patterns to match multiple sets of files:

buffer-static-upload -files "public/js/**/*.js,public/css/*.css,public/img/*.*" -bucket my-bucket

This will generate a staticAssets.json file in this directory like this:

{
  "public/css/style.css": "https://my-bucket.s3.amazonaws.com/public/css/style.11985b07e3121564a73d4d6821bfcfe7.css",
  "public/js/x/another.js": "https://my-bucket.s3.amazonaws.com/public/js/x/another.bfa2d0f60841707efe7be0a94c4caacf.js",
  "public/js/script.js": "https://my-bucket.s3.amazonaws.com/public/js/script.d55002b60fcfff0b3d355184d23af6f7.js",
  "public/img/home.jpg": "https://my-bucket.s3.amazonaws.com/public/img/home.jpg",
}

Note - The default bucket is used by multiple teams, so if you use that you must specify a directory to use for your project as not to create unnecessary collisions.
