Digital Marketplace GOV.UK Frontend ·

This repository provides a central repository for custom components used in the Digital Marketplace

The problem we are trying to solve:

it is difficult to ensure that all our applications are using the same version of GOV.UK Frontend and digitalmarketplace-frontend-toolkit (which is being replaced).
it is difficult to ensure that we are only importing and using css/js for components we are actually using and not been removed.

Quick start

1. Install with npm (recommended)

We recommend installing GOV.UK Frontend and Digital Marketplace GOV.UK Frontend using node package manager (npm).

npm install govuk-frontend digitalmarketplace-govuk-frontend

Digital Marketplace GOV.UK Frontend has GOV.UK Frontend as a peerDependency so you do not need to install GOV.UK Frontend with npm, however it is recommended.

2. Add GOV.UK Frontend to your Sass load paths

Digital Marketplace GOV.UK Frontend relies on GOV.UK Frontend being available to Sass.

If you're using Node Sass you can add GOV.UK Frontend to your Sass load paths using

{
  includePaths: ['node_modules/digitalmarketplace-govuk-frontend']
}

3. Load templates from GOV.UK Frontend

If you are using v2 of GOV.UK Frontend, you'll need to ensure the node_modules/govuk-frontend directory is loaded into your templating environment with a govuk prefix so that Digital Marketplace components can target the correct GOV.UK Frontend components.

With v3, targetting the node_modules/govuk-frontend directory is sufficient, as there is already a govuk subfolder.

Developing new components

We use gulp to automate various tasks. Below we will detail what each part of the process is and what task are run

1. Installing the repo

After cloning this repository you will need to run npm install. After npm has successfully installed all packages and dependencies, an npm postinstall script will automatically run to do the following tasks:

Removes the govuk folder containing govuk-frontend from src(if it exists)
Copy govuk-frontend from node_modules to src/govuk

The reason for copying govuk-frontend to src/govuk is to ensure that govuk/ is available for templates in testing and development environments.

2. Developing components/features and previewing

Run npm run dev

compiles sass and js from src and places in app/public
watch task for any file changes to src, compiles and reloads the browser (using browsersync)
Start the webserver and reload the server if any server config changes (using nodemon)

3. Testing features in apps

Follow the steps in docs/publishing-a-pre-release.md to push a branch to GitHub as a release that can be consumed by other NodeJS apps.

Alternatively, you can create a package locally using npm run build:

# in digitalmarketplace-govuk-frontend
$ npm run build
# change to an app
$ cd ../digitalmarketplace-user-frontend
$ npm install ../digitalmarketplace-govuk-frontend/package

3. Publishing

Follow the steps in docs/publishing.md.
