Convert ActionCable javascript to ES2015 modules with modern build environment We've replaced the sprockets `//= require` directives with ES2015 imports. As a result, the ActionCable javascript can now be compiled with rollup (like ActiveStorage already is). - Rename action_cable/index.js.erb -> action_cable/index.js - Add rake task to generate a javascript module of the ActionCable::INTERNAL ruby hash This will allow us to get rid of ERB from the actioncable javascript, since it is only used to interpolate ActionCable::INTERNAL.to_json. - Import INTERNAL directly in ActionCable Connection module This is necessary to remove a load-order dependency conflict in the rollup-compiled build. Using ActionCable.INTERNAL would result in a runtime error: ``` TypeError: Cannot read property 'INTERNAL' of undefined ``` because ActionCable.INTERNAL is not set before the Connection module is executed. All other ActionCable.* references are executed inside of the body of a function, so there is no load-order dependency there. - Add eslint and eslint-plugin-import devDependencies to actioncable These will be used to add a linting setup to actioncable like the one in activestorage. - Add .eslintrc to actioncable This lint configuration was copied from activestorage - Add lint script to actioncable This is the same as the lint script in activestorage - Add babel-core, babel-plugin-external-helpers, and babel-preset-env devDependencies to actioncable These will be used to add ES2015 transpilation support to actioncable like we have in activestorage. - Add .babelrc to actioncable This configuration was copied from activestorage - Enable loose mode in ActionCable's babel config This generates a smaller bundle when compiled - Add rollup devDependencies to actioncable These will be used to add a modern build pipeline to actioncable like the one in activestorage. - Add rollup config to actioncable This is essentially the same as the rollup config from activestorage - Add prebuild and build scripts to actioncable package These scripts were copied from activestorage - Invoke code generation task as part of actioncable's prebuild script This will guarantee that the action_cable/internal.js module is available at build time (which is important, because two other modules now depend on it). - Update actioncable package to reference the rollup-compiled files Now that we have a fully functional rollup pipeline in actioncable, we can use the compiled output in our npm package. - Remove build section from ActionCable blade config Now that rollup is responsible for building ActionCable, we can remove that responsibility from Blade. - Remove assets:compile and assets:verify tasks from ActionCable Now that we've added a compiled ActionCable bundle to version control, we don't need to compile and verify it at publish-time. (We're following the pattern set in ActiveStorage.) - Include compiled ActionCable javascript bundle in published gem This is necessary to maintain support for depending on the ActionCable javascript through the Sprockets asset pipeline. - Add compiled ActionCable bundle to version control This mirrors what we do in ActiveStorage, and allows ActionCable to continue to be consumed via the sprockets-based asset pipeline when using a git source instead of a published version of the gem.
