Probation Search Front-end Components

A Nunjucks component and Express middleware to search for probation cases.

Use this component to build probation case search functionality into your HMPPS service and deliver a consistent search experience to probation practitioners.

Try it out in the dev environment: https://probation-search-dev.hmpps.service.justice.gov.uk/examples

Get started

This guide assumes you are using the hmpps-template-typescript.

1. Install the dependency

npm install --save @ministryofjustice/probation-search-frontend

2. Add the Nunjucks component

Use the caseSearch component in your Nunjucks file:

{% from "probation/case-search/macro.njk" import caseSearch %}

{{ caseSearch({ 
    id: "search", 
    results: searchResults
}) }}

Full example: views/search.njk

3. Configure the Express routes

Create an instance of the CaseSearchService:

import CaseSearchService from '@ministryofjustice/probation-search-frontend/service/caseSearchService'

const searchService = new CaseSearchService({
  environment: config.environment,           // whether you want to search cases in the dev, preprod or prod environment 
  hmppsAuthClient: services.hmppsAuthClient, // a reference to your HMPPS Auth client
})

Full example: services/index.ts

Then use it to set up the post and get routes for your search page.

router.post('/search', searchService.post)
router.get('/search', searchService.get, (req, res) => res.render('pages/search'))

Full example: routes/search.ts

That's it! Start your service and visit http://localhost:3000/search to try it out.
