Tom Byers	672d4cb6e9	Make use of JS Modules less confusing ... It's not obvious how the code that includes JS Modules in the frontend build works. This adds lots of comments to explain the various bits and flattens `modules/all.mjs` to just be a single function that starts off the window.GOVUK namespace. Also removes `module/all.js` from the repo'. It's an artefact used by the frontend build so shouldn't be included as source code.	2019-11-22 17:45:45 +00:00
Tom Byers	efe7e2f35e	Add JS modules support & use for GOVUKFrontend ... The JS for GOVUKFrontend components is available individually so you can only include what you need: https://github.com/alphagov/govuk-frontend/blob/v2.13.0/docs/installation/installing-with-npm.md#option-2-import-javascript This uses the JS Modules syntax: *[JS module](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) Our JS is delivered as one file so we need to use a bundler to convert the modules to a single file. This adds a build step to transpile all modules into a single file, which is then added to the files combined into the one that get delivered. Rollup is used as the simplest bundler to use for this purpose. It also introduces the least boilerplate JS. Note: the CommonJS plugin is needed as GOV.UK Frontend components are published as UMD modules. In future, this work should let us work on this story dependencies: https://www.pivotaltracker.com/story/show/165380360	2019-11-22 17:45:45 +00:00
