S3 Plugin

Travis Badge Code Climate

This plugin will upload all built assets to s3

Install Instructions

$ npm i webpack-s3-plugin

Note: This plugin needs NodeJS > 0.12.0

Usage Instructions

I notice a lot of people are setting the directory option when the files are part of their build. Please don't set directory if your uploading your build. Using the directory option reads the files after compilation to upload instead of from the build process.

You can also use a credentials file from AWS.

s3Options default to ACL: 'public-read' so you may need to override if you have other needs. See #28

Require webpack-s3-plugin
var S3Plugin = require('webpack-s3-plugin')
With exclude
var config = {
  plugins: [
    new S3Plugin({
      // Exclude uploading of html
      exclude: /.*\.html$/,
      // s3Options are required
      s3Options: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
        region: 'us-west-1'
      },
      s3UploadOptions: {
        Bucket: 'MyBucket'
      },
      cdnizerOptions: {
        defaultCDNBase: 'http://asdf.ca'
      }
    })
  ]
}
With include
var config = {
  plugins: [
    new S3Plugin({
      // Only upload css and js
      include: /.*\.(css|js)/,
      // s3Options are required
      s3Options: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      },
      s3UploadOptions: {
        Bucket: 'MyBucket'
      }
    })
  ]
}
Advanced include and exclude rules

include and exclude rules behave similarly to Webpack's loader options. In addition to a RegExp you can pass a function which will be called with the path as its first argument. Returning a truthy value will match the rule. You can also pass an Array of rules, all of which must pass for the file to be included or excluded.

import isGitIgnored from 'is-gitignored'

// Up to you how to handle this
var isPathOkToUpload = function(path) {
  return require('my-projects-publishing-rules').checkFile(path)
}

var config = {
  plugins: [
    new S3Plugin({
      // Only upload css and js and only the paths that our rules database allows
      include: [
        /.*\.(css|js)/,
        function(path) { isPathOkToUpload(path) }
      ],

      // function to check if the path is gitignored
      exclude: isGitIgnored,

      // s3Options are required
      s3Options: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      },
      s3UploadOptions: {
        Bucket: 'MyBucket'
      }
    })
  ]
}
With basePathTransform
import gitsha from 'gitsha'

var addSha = function() {
  return new Promise(function(resolve, reject) {
    gitsha(__dirname, function(error, output) {
      if(error)
        reject(error)
      else
       // resolve to first 5 characters of sha
       resolve(output.slice(0, 5))
    })
  })
}

var config = {
  plugins: [
    new S3Plugin({
      s3Options: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      },
      s3UploadOptions: {
        Bucket: 'MyBucket'
      },
      basePathTransform: addSha
    })
  ]
}


// Will output to /${mySha}/${fileName}
With CloudFront invalidation
var config = {
  plugins: [
    new S3Plugin({
      s3Options: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      },
      s3UploadOptions: {
        Bucket: 'MyBucket'
      },
      cloudfrontInvalidateOptions: {
        DistributionId: process.env.CLOUDFRONT_DISTRIBUTION_ID,
        Items: ["/*"]
      }
    })
  ]
}
With Dynamic Upload Options
var config = {
  plugins: [
    new S3Plugin({
      s3Options: {
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
      },
      s3UploadOptions: {
        Bucket: 'MyBucket',
        ContentEncoding(fileName) {
          if (/\.gz/.test(fileName))
            return 'gzip'
        },

        ContentType(fileName) {
          if (/\.js/.test(fileName))
            return 'application/javascript'
          else
            return 'text/plain'
        }
      }
    })
  ]
}

  • noCdnizer: Disable cdnizer (defaults true if no cdnizerOptions passed)
  • cdnizerOptions: options to pass to cdnizer

  • progress: Enable progress bar (defaults true)

Contributing

All contributions are welcome. Please make a pull request and make sure things still pass after running npm run test For tests you will need to either have the environment variables set or setup a .env file. There's a .env.sample so you can cp .env.sample .env and fill it in. Make sure to add any new environment variables.

Commands to be aware of

WARNING: The test suit generates random files for certain checks. Ensure you delete files leftover on your Bucket.
  • npm run test - Run test suit (You must have the .env file setup)
  • npm run build - Run build
