asset-uploader

Library for uploading web assets to Amazon S3 or Azure Storage to support a "Never expire" policy.

It uploads files in a directory, changing their name to a hashed version, and provides a JSON lookup file.

For example, a directory containing 1 file "/css/styles.css":

It will generate an md5 hash of the file, and upload it as "/css/styles.<hash>.css".

This will then be written to a manifest JSON file as:

{
    "/css/styles.css": "/css/styles.d41d8cd98f00b204e9800998ecf8427e.css"
}

Later you can use the manifest file when generating HTML.

Usage

Uploading assets and generating a manifest.json

const AssetUploader = require('asset-uploader')

const provider = new AssetUploader.Providers.S3('bucket-name')
const assetUploader = new AssetUploader(provider)

assetUploader.upload('./assets', '/**/*', './manifest.json')
.then(() => {
    console.log('wrote ./manifest.json!')
})

Lookup assets when running in production

var resolver = new assetUploader.Resolver('./manifest.json')
resolver.resolve('/css/styles.css')
// returns '/css/styles.d41d8cd98f00b204e9800998ecf8427e.css'
