Divorce Document Express Handler

A simple module to handle getting documents

Getting started

Attach document handler to express app

Attach the document get route to the app like so:

const { initDocumentHandler } = require('@hmcts/div-document-express-handler');
const express = require('express');
const idam = require('services/idam');

const app = express();

const middleware = [ idam.protect() ];
const args = {
  // string to define path to attach document donwload handler, default: '/document-download/:documentId' *optional*
  uri: '/document-download/:documentId',
  // only allow files that include the following strings *optional*
  // can be a function or an array
  documentWhiteList: (req, res) => {
    return ['fileName1IncludesString', 'fileName2IncludesString'];
  },
  // string to specifiy auth token cookie, default: '__auth-token' *optional*
  authorizationTokenCookieName: '__auth-token',
  // string to specify the service to fetch the documents from *required*
  documentServiceUrl: 'service-url',
  // array to paths where file collections are stored *required*
  // this is used to get the file id from the session given the file name. all downloadable
  // files must be included in these paths
  sessionFileCollectionsPaths: ['case.data.d8', 'files']
};
initDocumentHandler(app, middleware, args);

Generate urls and file types from file system

Here is an example how to generate file urls and types:

const { Page } = require('@hmcts/one-per-page');
const { createUris } = require('@hmcts/div-document-express-handler');

class Step extends Page {
  static get path() {
    return 'some-path';
  }

  get downloadableFiles() {
    const args = {
      // string to define uri where document donwload handler is attached, default: '/document-download/:documentId' *optional*
      uri: 'some-url',
      // only allow files that include the following strings *optional*
      documentWhiteList: ['someOtherFile']
    };
    // The first argument is an array of files expected the following format:
    // this.req.session.files = [
    //   {
    //     "id": "401ab79e-34cb-4570-9f2f-4cf9357dc1ec",
    //     "value": {
    //       "DocumentFileName" : "someOtherFile1552043698652633"
    //     }
    //   },
    //   {
    //     "id": "401ab79e-34cb-4570-9f2f-4cf9357dc1ec",
    //     "value": {
    //       "DocumentFileName" : "someFile1552043698652633"
    //     }
    //   }
    // ]
    return createUris(this.req.session.files, args);
  }
}

module.exports = Step;

To render output using look-and-feel:

template.html:

{% from "look-and-feel/components/document-list.njk" import documentList %}

<h3 class="heading-small" id="subsection-title">Download your documents</h3>

{{ documentList(downloadableFiles, content.files) }}

main.scss:

@import 'look-and-feel/all';

or to import specific styles for document-list

@import 'look-and-feel/document-list';

content.json:

  {
    "en": {
      "files": {
        "d8petition": "Original Petition",
        "aosinvitation": "Respondent Response",
        "co-respondentaosinvitation": "Co-Respondent Response"
      }
    }
  }

This will print the file list out.
