Introduction

Easily build GOV.UK style one question per page services using express, nunjucks and webpack.

Features

One per page solves a number of hard problems in building a one question per page service:

• Capturing and validating users answers
• Navigating branching journeys
• Session management
• Content internationalisation
• Template management

All documentation is available at https://one-per-page.herokuapp.com

Usage

Add one-per-page and look-and-feel to your package.json:

> yarn add @hmcts/one-per-page @hmcts/look-and-feel

Then create a few steps and wire them to your express app:

app.js

const app = express();

class Start extends EntryPoint {
  next() {
    return goTo(this.journey.steps.CheckYourAnswers);
  }
}

class Name extends Question {
  get form() {
    return form({
      firstName: text.joi('Enter your first name', Joi.string().required()),
      lastName: text.joi('Enter your last name', Joi.string().required()),
    });
  }
  next() {
    return goTo(this.journey.steps.CheckYourAnswers);
  }
}

journey(app, {
  steps: [
    Start,
    Name,
    CheckYourAnswers
  ]
});

app.listen(3000);

And create a template for your step:

Name.template.html

{% extends "look-and-feel/layouts/question.html" %}
{% from "look-and-feel/components/fields.njk" import textbox %}

{% set title %}What is your name?{% endset %}

{% block fields %}
  {{ textbox(fields.firstName, "First Name") }}
  {{ textbox(fields.lastName, "Last Name") }}
{% endblock %}

@hmcts/look-and-feel helps with creating templates

Then start your app:

> node app.js
# listening on port 3000
