CHANGELOG.md

Unreleased

• Allow dev server connect timeout (in seconds) to be configurable, default: 0.01

# Change to 1s
Webpacker.dev_server.connect_timeout = 1

[3.0.1] - 2017-09-01

Fixed

• Missing node_modules/.bin/* files by bumping minimum Yarn version to 0.25.2 #727

• webpacker:compile task so that fails properly when webpack compilation fails #728

• Rack dev server proxy middleware when served under another proxy (example: pow), which uses HTTP_X_FORWARDED_HOST header resulting in 404 for webpacker assets

• Make sure tagged logger works with rails < 5 #716

Added

• Allow webpack dev server listen host/ip to be configurable using additional --listen-host option

  ./bin/webpack-dev-server --listen-host 0.0.0.0 --host localhost

Removed

• watchContentBase from devServer config so it doesn't unncessarily trigger live reload when manifest changes. If you have applied this workaround from #724, please revert the change from config/webpack/development.js since this is now fixed.

[3.0.0] - 2017-08-30

Added

• resolved_paths option to allow adding additional paths webpack should lookup when resolving modules

  # config/webpacker.yml
  # Additional paths webpack should lookup modules
  resolved_paths: [] # empty by default

• Webpacker::Compiler.fresh? and Webpacker::Compiler.stale? answer the question of whether compilation is needed. The old Webpacker::Compiler.compile? predicate is deprecated.

• Dev server config class that exposes config options through singleton.

  Webpacker.dev_server.running?

• Rack middleware proxies webpacker requests to dev server so we can always serve from same-origin and the lookup works out of the box - no more paths prefixing

• env attribute on Webpacker::Compiler allows setting custom environment variables that the compilation is being run with

  Webpacker::Compiler.env['FRONTEND_API_KEY'] = 'your_secret_key'

Breaking changes

Note: requires running bundle exec rails webpacker:install

config/webpack/**/*.js:

• The majority of this config moved to the @rails/webpacker npm package. webpacker:install only creates config/webpack/{environment,development,test,production}.js now so if you're upgrading from a previous version you can remove all other files.

webpacker.yml:

• Move dev-server config options under defaults so it's transparently available in all environments

• Add new HMR option for hot-module-replacement

• Add HTTPS

Removed

• Host info from manifest.json, now looks like this:

  {
    "hello_react.js": "/packs/hello_react.js"
  }

Fixed

• Update webpack-dev-server.tt to respect RAILS_ENV and NODE_ENV values #502
• Use 0.0.0.0 as default listen address for webpack-dev-server
• Serve assets using localhost from dev server - #424

  dev_server:
    host: localhost

• On Windows, ruby bin/webpacker and ruby bin/webpacker-dev-server will now bypass yarn, and execute via node_modules/.bin directly - #584

Breaking changes

• Add compile and cache_path options to config/webpacker.yml for configuring lazy compilation of packs when a file under tracked paths is changed #503. To enable expected behavior, update config/webpacker.yml:

    default: &default
      cache_path: tmp/cache/webpacker
    test:
      compile: true
  
    development:
      compile: true
  
    production:
      compile: false

• Make test compilation cacheable and configurable so that the lazy compilation only triggers if files are changed under tracked paths. Following paths are watched by default -

    ["app/javascript/**/*", "yarn.lock", "package.json", "config/webpack/**/*"]

  To add more paths:

  # config/initializers/webpacker.rb or config/application.rb
  Webpacker::Compiler.watched_paths << 'bower_components'

[2.0] - 2017-05-24

Fixed

• Update .babelrc to fix compilation issues - #306

• Duplicated asset hosts - #320, #397

• Missing asset host when defined as a Proc or on ActionController::Base.asset_host directly - #397

• Incorrect asset host when running webpacker:compile or bin/webpack in development mode - #397

• Update webpacker:compile task to use stdout and stderr for better logging - #395

• ARGV support for webpack-dev-server - #286

Added

• Elm support. You can now add Elm support via the following methods:

  • New app: rails new <app> --webpack=elm
  • Within an existing app: rails webpacker:install:elm

• Support for custom public_output_path paths independent of source_entry_path in config/webpacker.yml. output is also now relative to public/. - #397

  Before (compile to public/packs):

    source_entry_path: packs
    public_output_path: packs

  After (compile to public/sweet/js):

    source_entry_path: packs
    public_output_path: sweet/js

• https option to use https mode, particularly on platforms like - https://community.c9.io/t/running-a-rails-app/1615 or locally - #176

• [Babel] Dynamic import() and Class Fields and Static Properties babel plugin to .babelrc

{
  "presets": [
    ["env", {
      "modules": false,
      "targets": {
        "browsers": "> 1%",
        "uglify": true
      },
      "useBuiltIns": true
    }]
  ],

  "plugins": [
    "syntax-dynamic-import",
    "transform-class-properties", { "spec": true }
  ]
}

• Source-map support for production bundle

Breaking Change

• Consolidate and flatten paths.yml and development.server.yml config into one file - config/webpacker.yml - #403. This is a breaking change and requires you to re-install webpacker and cleanup old configuration files.

  bundle update webpacker
  bundle exec rails webpacker:install
  
  # Remove old/unused configuration files
  rm config/webpack/paths.yml
  rm config/webpack/development.server.yml
  rm config/webpack/development.server.js

  Warning: For now you also have to add a pattern in .gitignore by hand.

   /public/packs
  +/public/packs-test
   /node_modules
