Fez frontend

AWS Codebuild Status for uqlibrary/fez-frontend

Fez frontend is a web interface application for digital repository. Staging/Production release notes

UQ's branding for Fez is UQ eSpace.

IMPORTANT NOTE

eSpace prodtest is a production environment

This means that it's exactly like production, except for the git branch that uses. This is useful for carefully* testing anything that might break production before pushing to the actual branch.

*carefully: any actions (e.g. creating, editing, deleting records) performed in eSpace prodtest will result in changes to production. This includes email notifications, 3rd party services integrations and everything else

Technology

  • Code: React (~20.11), Javascript (ES2015 - Babel), Immutable, SASS
  • State: Redux, ReduxForm
  • Design: Google Material Design - MUI 5 (see notes below on the upgrade to MUI 5)
  • Build and dev tools: Webpack
  • Unit tests: Jest
  • E2E tests: Cypress
  • Supported Browsers

Development

  • This project uses npm for dependency management. Make sure npm is installed on your machine by following the instructions at https://docs.npmjs.com/downloading-and-installing-node-js-and-npm

  • This project uses nvm for node version switching. To install or update node, run one of the installation commands detailed at https://github.com/nvm-sh/nvm#install--update-script. For example:

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

  • The nvm installation process will update your environmental variables. You will either need to restart your terminal for the changes to take effect, or run the export command shown at the end of the nvm installation process. For example (using the curl command above):

    export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

  • With nvm installed and/or updated, install node version of at least 20.11.0:

    nvm install 20.11.0

  • Switch to the node version just installed and begin initial setup:

    nvm use 20.11.0 && npm i -g npm@10.4.0 jest webpack-dev-server

    See gotchas below for watchouts regarding nvm versions

  • if you are on a Mac, ensure xcode with developer applications is installed

  • In the root folder of fez-frontend install the required npm modules:

    npm install

  • Finally, before starting one of the npm run commands shown below, ensure you have duplicated the example.env file in the root of fez-frontend and named the duplicate file .env

You should now be able to run one of the following commands from the CLI:

  • npm ci - when weird errors happen your local npm probably doesnt match the latest project requirements, this clears & reinstalls npm packages

  • npm run start

  • npm run start:mock

  • npm run start:url to view local code against staging api

    setup steps:

    • update file /etc/hosts (sudo required)

      ensure dev-espace.library.uq.edu.au is set to your local IP, or add an entry for it:

      e.g. 172.16.0.20 dev-espace.library.uq.edu.au

    • edit project file .env

      set API_URL to https://api.library.uq.edu.au/staging/

    • start the web server (previous steps must be done before this point)

      in the terminal, issue npm run start:url

    • launch your browser with CORS disabled:

      Linux: google-chrome --disable-web-security --user-data-dir=/tmp/chrome-dev

      Mac: open -na Google\ Chrome --args --user-data-dir="/tmp/chrome_dev_test" --disable-web-security

      Windows:"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:/ChromeDevSession"

    • Supply user cookie values

      in CORS-disabled browser,

    • load site

      in CORS-disabled browser, visit http://dev-espace.library.uq.edu.au:3000/

    • note: for Hot Reloading to work in IntelliJ products, turn "safe write" off in the settings

  • npm run start:build

  • npm run start:build:e2e

    • runs production build version on http://localhost:9000/
    • uses mock data from src/mock
    • async loading is not working since chunks are not saved, navigate directly to required routes

  • npm run test:cs

    • Runs Prettier and ESLint checks on all Javascript files in the project, then lists files with code style issues. Check the other npm scripts for ways to fix the issues automatically if possible.

  • npm run test:e2e:cc

    • Runs Cypress tests with code coverage checks. HTML report will be available under coverage/cypress while and after tests run.

Mock data is provided for all pages and actions under src/mock/.

Development notes

Git safety checks

  • Run the following in the project root directory to install the pre-commit hook:

    ln -sf "../../scripts/pre-commit" ".git/hooks/pre-commit"

    It does two things:

    • Prevent direct commits to the staging branch.
    • Run prettier-eslint automatically before every local commit

  • Run the following in the project root directory to prevent accidental merges from the staging branch:

      ln -sf "../../scripts/prepare-commit-msg" ".git/hooks/prepare-commit-msg"

Naming conventions

  • React components and files of components and related files (eg scss) are to be named with upper case (eg MenuDrawer.js). Do not add UQ, UQLibrary or similar prefixes to components
  • Other files are to be named with lower case (eg index.js, reducerX.js)
Action types naming conventions

  • Action transformers naming: use [verb][noun] format (if appropriate) to indicate what method returns, eg unclaimRecordContributorsIdSearchKey(), getRecordContributorsIdSearchKey(), etc

  • Keep to the following naming format [OBJECT]_[STATUS] or [NOUN]_[VERB]:

  • LATEST_PUBLICATIONS_LOADING

  • LATEST_PUBLICATIONS_LOADED

  • LATEST_PUBLICATIONS_FAILED

or

  • APP_ALERT_SHOW
  • APP_ALERT_HIDE

Optimisation

To keep initial load to a minimum, the following optimisations have been added to the project:

  • Async (lazy) loading of non-essential (essential components are only those components user can see on public pages when not authenticated)
  • Splitting essential vendor libraries out ('react', 'react-dom', 'react-router-dom', 'redux', 'react-redux') - those libraries do not change often and will be cached by the browser
  • Optimise rendering of the components (in ReactJs 15 use react-addon-perf) to minimize wasteful rendering of components, implement PureComponent or shouldComponentUpdate()
  • Locale package is split into smaller chunks to avoid loading it all at once:
    • publicationForm.js locale is loaded only when PublicationForm component is loaded
    • Other locale files are not too big, all bundled into one for now

Reusable WebComponents

eSpace currently takes only Alerts from Reusable - at some point in the future we may upgrade to use the standard uq header.

Staging branch calls Reusable staging branch - all other branches call production Reusable, by default.

To use local reusable in your local dev, swap the value of reusablejs in webpack.config.js (and restart your npm sun start:mock)

Webpack

version: 5

As of March 2023, Fez uses Webpack version 5.

  • Use of Asset Loader instead of File Loader when emitting assets. Important Note that on dev branches (development.library.edu.au) any icons referenced from CSS (e.g. as background images) or images loaded in to components via an import statement will not appear in the web page. This is due to the lengthy path structure of the URL on dev branches, and the inclusion of a hash (#). These assets are all generated in the the root /assets folder and will work as expected on staging and prod branches.
    test: /\.(png|jp(e*)g|svg|gif)$/,
    type: 'asset/resource',
    generator: {
        publicPath: '/assets/',
        outputPath: 'assets/',
        filename: '[hash][ext]',
    },
},
  • CSS and JS assets now reside in a subfolder with the Hash of the most current Git Commit. Filenames continue to include contentHash in the name (Note that CSS was moved from the root to a frontend-css folder.).
output: {
      filename: `frontend-js/${currentCommitHash}/[name]-[contenthash].min.js`,
}

new MiniCssExtractPlugin({
            filename: `frontend-css/${currentCommitHash}/[name]-[contenthash].min.css`,
})

  • See webpack-dist.config.js for details of the currentCommitHash variable and the outputLastCommitHashes function, which builds a hash.txt file that includes the last 20 commit hashes.

  • The outputting of source-maps has been removed.

  • The PWA package has been disabled as it no longer served a purpose.

version: 4

Webpack plugins

  • SplitChunksPlugin

    optimization: {
      splitChunks: {
          automaticNameDelimiter: '-',
          cacheGroups: {
              commons: {
                  chunks: 'all'
              }
          }
      },
      minimizer: [
          new TerserPlugin({
              sourceMap: true,
              parallel: true
          })
      ]
  },

  • Terser/tree shake: used with split chunks built-in plugin in webpack 4

    new TerserPlugin({ sourceMap: true });

  • minify in deployment:

    new webpack.DefinePlugin({
  __DEVELOPMENT__: !process.env.CI_BRANCH,                    //  always production build on CI
  'process.env.NODE_ENV': JSON.stringify('production'),       //  always production build on CI
  ...
})

  • remove momentjs locale:

    new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/);

React StrictMode

At the time of writing, StrictMode has been enabled for a subset of components only. Redux Forms has been deprecated, causing StrictMode to output numerous console errors that can not be directly fixed.

Since Redux Form is mostly used in admin pages, these routes and select others have been excluded from StrictMode until such time that Redux Form is replaced in the repo. Look to src/modules/App/components/App.js for the implementation of the StrictModeConditional HoC that enables this selective application of StrictMode.

Gotchas

  • Because FE is served from cloudFront, add a behaviour to serve css/js filename patterns. e.g. behaviours have been added for main-* and commons-* files.

  • if you can't get eg https://fez-staging.library.uq.edu.au/view/UQ:e6c5854 to load the new FE (it always loads legacy) you can use the alternate url of https://fez-staging.library.uq.edu.au/view_new/UQ:e6c5854

  • The eSpace API always returns a 200 for a GET request to /fez-author. For this reason, checking for the presence of the author (e.g. this.props.author) is not enough to determine if the logged-in user is an author or not. This can be done the following check: this.props.autho?.aut_id or by checking for the response of author details API endpoint e.g. this.props.authorDetails

  • Be aware that nvm will use the default version of node whenever a new terminal window is opened. This may catch you out if you are updating environmental variables and closing/opening Terminal as mentioned earlier.

    To check what version is in use:

    nvm ls

    will display similair to:

    v14.7.0
->     v16.13.2
default -> 14.7.0 (-> v14.7.0)
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v16.13.2) (default)
stable -> 16.13 (-> v16.13.2) (default)
lts/* -> lts/gallium (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.10 (-> N/A)
lts/fermium -> v14.19.0 (-> N/A)
lts/gallium -> v16.14.0 (-> N/A)

    Note the default value above (14.7.0)

    To ensure you're always using the correct version of Node, you can set the default nvm will use with:

    nvm alias default 16.13.2

    which when checked should give you something like this:

    nvm ls

v14.7.0
->     v16.13.2
default -> 16.13.2 (-> v16.13.2)
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v16.13.2) (default)
stable -> 16.13 (-> v16.13.2) (default)
lts/* -> lts/gallium (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.10 (-> N/A)
lts/fermium -> v14.19.0 (-> N/A)
lts/gallium -> v16.14.0 (-> N/A)

    Be sure to check your nvm node version if your unit tests fail to run (this typically will happen if you change your repo from package-lock.json version 1 to 2, including updating the node and npm versions as mentioned above).

  • If you wish to reference static images in the public/images folder outside of src, you must use require() to bring them in to your component. This is due to a hashing process during build that moves and renames images to an assets folder on S3.

So instead of:

<img src='/images/someimage.jpg'>

use:

const myImage = require(../../public/images/someimage.jpg) // your path with depend upon where you're referencing the image in the hierarchy
<img src={myImage}>
// or in styles
backgroundImage: `url(${myImage})`

Also be wary of the different environments your code will deploy to, e.g. dev branch, staging, production. Dev branches work slightly different to the other two when it comes to using absolute vs relative paths within IMG elements, due to how the dev server must host multiple branches each with their own build (note this is not an issue if using the image in a style, as shown above). Typically for localhost, staging and production you'll need to reference your image from the root, by adding a leading \. However, this won't work on the development server, which requires an image reference without the leading slash. To handle this, use the IS_DEVELOPMENT_SERVER constant in src/config/general.js to conditionally add a leading \ when you output your image path, or leverage the convenience function getRequiredImagePath:

const myImagePath = `${!IS_DEVELOPMENT_SERVER ? '/' : ''}${myImage}`;

//or

const myImagePath = getRequiredImagePath(myImage);

Optimisation Guidelines

  • do not use functional components

  • try to simplify props

  • component should extend React.PureComponent if props are simple

  • component should extend React.Component, shouldComponentUpdate() should be implemented if props have objects

  • import explicit and specific components (do not import all):

    • DO NOT import { Button } from 'material-ui';
    • DO import { Button } from 'material-ui/Button';

  • any set of components which is not required in the initial load, eg PublicationForm, FixForm, ClaimForm etc, should lazy loaded using <Async>

    const PublicationsList = (componentProps) => (<Async load={import ('modules/SharedComponents/PublicationsList/components/PublicationsLis t')}  componentProps={componentProps} />);
...
<PublicationsList {...props} />

  • make sure to check BundleAnalyzerPlugin output locally by running npm run build or npm run analyse:

    • main-###.js file should not exceed 1Mb
    • main-###.js should not include any non-essential libraries

Exception handling

  • any custom reject() by promises should return an object with status and message defined {status: 401, message: 'Unauthorised user'} Example
  • any custom catch() methods of promises should process known errors and throw other errors. Example

Testing

Unit testing

Jest is used as testing tool for unit tests. Any HTMl markup is to be tested with snapshots.

  • install jest npm install jest -g
  • run tests npm test

Before committing changes, locally run tests and update snapshots (if required). To update snapshots run npm run test:unit:update.

Code coverage is available (after running npm test)

Guidelines

E2E testing

We are using Cypress for our e2e UI testing.

NOTE: If you are getting an error Failed to deserialize the V8 snapshot blob when running tests - be sure to delete your cypress cache - Windows: \AppData\Local\Cypress\Cache

To run tests, first start the build, using mock data, ie npm run start:mock

Then:

  • use npm run cypress:run
  • or to open the Cypress UI use npm run cypress:open
  • or to watch the tests npm run cypress:watch.

Before pushing to a branch make sure to run npm run test:all. This runs the unit and cypress tests.

Codebuild runs npm run test:e2e:ci1 npm run test:e2e:ci2 and uses webpack-dev-server to serve the frontend with mock data.

If there build issues in the CI server, you can enable the dashboard by updating bin/codebuild-test.sh to run npm run test:e2e:ci1:dashboard npm run test:e2e:ci2:dashboard. You can the watch video recordings of any failed test runs and view some debug messages via the Cypress dashboard. We have open-source license which allows unlimited runs.

To manage the account, the admin username/pass is in PasswordState under "GitHub Cypress.io Admin User" (login to Github as this user, then use the github account to log into Cypress).

If you want Codebuild to run cypress tests before you merge to master, include the text cypress in the branch name and push and cypress tests will be run on that branch (set up in bin/codebuild-test.sh).

Standardised selectors to target elements

  • We are following the best practice recommended by cypress to target elements using data-testid attribute

  • Please have a look at below table for some current examples in eSpace frontend:

Element prop for ID ID attached to native elements for targetting
TextField textFieldId="rek-title" <input id="rek-title-input"/> <label id="rek-title-label"/>

Some tricks and tips

  • When simulating clicks which result in non-trivial DOM changes, you might need to cy.wait(1000); to wait 1 second after the click before posing any expectations. If possible, use cy.waitUntil() instead to wait for a particular condition to be true.

  • Custom cypress commands can be added to cypress/support to abstract out common actions. For example:

    • When the form you are writing tests for has a browser alert box to prevent navigating away before its complete, add this to the top of your test to unbind the unload event handler. The issue might only present itself when trying to do another test by navigating to a new url, which never finishes loading because the browser is waiting for the alert from the previous page to be dismissed, which is actually not visible in Cypress UI!

      afterEach(() => {
  cy.killWindowUnloadHandler();
});

    • When using the MUI dialog confirmation, use the following for navigating to the homepage:

      cy.navToHomeFromMenu(locale);

      where locale is:

      {
  confirmationTitle: '(Title of the confirmation dialogue)',
  confirmButtonLabel: '(Text of the "Yes" button)'
}

      See cypress/support/commands.js to see how that works.

  • If a test occasionally fails as "requires a DOM element." add a .should() test after the .get(), to make it wait for the element to appear (.should() loops)

Gotchas

When running npm test and related scripts natively in linux (without using a VM), jest can be quite demanding making the OS unresponsive.

One way to avoid this is to restrict the number of CPU cores through jest's --maxWorkers option.

NODE_ENV=test FULL_PATH=http://localhost node --expose-gc ./node_modules/.bin/jest --logHeapUsage --maxWorkers=50%

Mocking

To run website on mock data run npm run start:mock webserver will start on http://localhost:3000/

The project allows the user to "login" as any test user. Simply add ?user=<username> to the request and it will log you in as that user. Usernames can be found in the src/mock/data/accounts.js file.

So an example staff link for an example admin edit page will be http://localhost:3000/admin/edit/UQ:358319?user=uqstaff

The following access is required:

User type masquerade admin Resulting access
general user false false no masquerade, no admin, no csv ingest
support staff readonly false readonly masquerade, no admin, no csv ingest
admin or developer full true full masquerade, admin, csv ingest
digiteam false true no masquerade, admin (side effect), csv ingest

masquerade - on account record (CURRENT_ACCOUNT_API) eg https://api.library.uq.edu.au/staging/account, canMasquerade = true or false; when true, masqueradeType = full or readonly

admin - on author record (AUTHOR_DETAILS_API) eg https://api.library.uq.edu.au/staging/authors/details/uqldegro, is_administrator = 0 or 1

(there is also is_super_administrator, 0 or 1, which gives access to the security tab)

Reviewing

A Self-review checklist is here in the ISRS Collection.

Ask for review from team-mates if you'd like other eyes on your changes.

Deployment

Application deployment is 100% automated (except for prodtest) using AWS Codebuild (and Codepipeline), and is hosted in S3. All testing and deployment commands and configuration are stored in the buildspec yaml files in the repo. All secrets (access keys and tokens for PT, Cypress, Sentry and Google) are stored in AWS Parameter Store, and then populated into ENV variables in those buildspec yaml files. Deployment pipelines are setup for branches: "master", "staging", "prodtest", "production" and several key branches starting with "feature-".

Staging/production/prodtest build has routing based on createBrowserHistory(), other branches rely on createHashHistory() due to URL/Cloudfront restrictions

Should you need to find your feature branch files on S3, they are here (most common use is to cleanup after you finish with a feature branch: remove the S3 sub-folder from this location, the git branch, and the AWS pipeline).

Note: prodtest requires a manual click for its deployment to happen: go to this link and click the orange release changes button.

Gotchas

There are some build steps that are exclusive to master, staging and production branches:

  • npm run test:unit:ci1
  • npm run test:e2e:dashboard

This means that even when a given branch passes tests and builds successfully in CB, it doesn't necessary mean that it's free issues.

In order to identify possible issues before pushing master upstream, make sure to run the commands above locally after merging your changes to that branch.

For more details, look at ./bin/codebuild-test.sh

Google Analytics integration

Fez-frontend includes GTM (Google Tag Manager). GTM is set at webpack build time in webpack configuration. It can be setup as an environmental variable at CI level if required.

GTM is very flexible and easy to configure to track required events. See more details on Google Analytics

MUI v5 Upgrade

February 2023

The upgrade from Material-UI version 4 (MUI4) to MUI version 5 (MUI5) was completed in Feb 23, and with it game a few watchaouts for anyone repeating the process in the future as well as current devs working with the new library:

  1. MUI5 has redefined the default responsive breakpoint values (https://mui.com/material-ui/customization/breakpoints/), and devs writing tests or making use of, for example useMediaQuery, should be aware of the new breakpoints and adjust code appropriately.
  • MUI4 values (px): xs: 0, sm: 600, md: 960, lg: 1280, xl: 1920
  • MUI5 values (px): xs: 0, sm: 600, md: 900, lg: 1200, xl: 1536
  1. MUI5 deprecated the widely used <Hidden> component. For this migration, the new sx element property was used to replace <Hidden> in most circumstances. Using sx does, however, raise a few awareness points:
  • Code using sx for breakpoints will rely on the browser's CSS engine to determine when something is visible or not. This is in contrast to how <Hidden> was used in our codebase, which used JS to control inserting or deleting DOM elements.
  • When writing tests you must bear in mind the above, because JSDOM does not support a fully fledged CSS engine (https://github.com/jsdom/jsdom/blob/8e3a568d504353270691b5955af505155ae368bf/lib/jsdom/level2/style.js#L17). This is particularly important when writing tests that wish to check if an element is visible or not based on, for example browser window width (i.e. responsive design). These tests, in conjunction with sx, will fail because all elements are always visible due to the lack of a CSS engine. The recommendation here is to move these sorts of tests in to a Cypress spec, where you can assuredly test for element visibility using, for example to.be.visible. Note that this does imply that you will need to run convergence coverage checks that merge both Jest and Cypress in order to see your true code coverage.
  • An alternative to the above, but only to be used where it makes the most sense for performance and/or testing burden, is using the hook useMediaQuery in your code to include or exclude parts of a component in the render block. This is JS based and therefore will work as expected in Jest tests.
  1. Enzyme snapshots have been regenerated to account for the new MUI5 components, and as such many tests also needed to be updated to match changes in the snapshot structure. A common difference encountered was references to a component such as WithStyles(ForwardRef(Button)) had become ForwardRef(Button), and will easy to fix is worth remembering. Check your snapshot structure if you find MUI4 Enzyme tests are failing.
  2. In a great many cases it was no longer possible to run shallow Enzyme tests against components. This appears to be caused by MUI5 components using Theme requiring a theme provider, and as such these tests were failing when a component in the tree tried to access a theme via useStyles. The MUI5 testing page has been updated and no longer recommend testing snapshots at all (see v4 version here). We will continue to do so, however, so the solution moving forward is to use Mount to create a deep snapshot. In most cases existing Enzyme tests can be easily updated to produce a deep snapshot by updating the setup method to include a 3rd parameter of the getElement function: return getElement(PublicationCitation, props, {isShallow: false}); NB: this is just for illustration - a better approach is to include an args property in the setup function signature i.e. function setup(testProps = {}, args = { isShallow: false }). Note that your snapshot will need regenerating and tests modified to handle the new snapshot structure.
  3. If an Enzyme test needs to refer to wrapper.instance(), and the component requires a Theme as mentioned above, and the instance is spying on a function, ensure the wrapper finds the component's name before calling instance. e.g. wrapper.find(‘class name’).instance().
  4. Enzyme tests that simulate a click or other user action, and have been updated to generate deep Merge snapshots, will likely need updating to find the actual button in the tree before firing the event (see wojtekmaj/enzyme-adapter-react-17#45). For example, the click event for the element: const playElement = wrapper.find('ForwardRef(IconButton)#playButton'); would need changing from: playElement.simulate('click'); to: playElement.find('button').simulate('click');
  5. For Jest testing a component that uses useTheme, ensure you use the rtlRender renderer in your setup function. This will insert a ThemeRenderer in the tree and will allow your tests to pass. See src/utils/test-utils.js for the code behind this.
  6. When testing dropdown boxes/lists (for example, with the AutoCompleteAsynchronousField component), your tests must ensure focus is in the target component before you attempt to change the contents of the input (fireEvent.change()), otherwise the expected popup window of options will not appear.
  7. By default, the MUI5 ToolTips component no longer uses a title attribute to hold the wrapped component's tooltip text. Instead the aria-label attribute is used, and tests need to be updated to reflect this. This behaviour can be changed by including the describeChild, however be aware of potential accessibility issues. Note also that there are some elements that can not have aria-label as an attribute (see dequelabs/axe-core#3205), and as such you may encounter Cypress Axe failures if you do not use the describeChild attribute.
  8. Cypress tests that look to enter text in to a multiline text field (i.e HMTL TextArea) may fail due to MUI5 inserting two TextArea elements for each use of <TextField multiline>. Your tests should pick the first instance of the TextArea element for testing. No official information on this behaviour could be found at time of writing.
  9. MyEditorialAppointments component adds a custom DatePicker bar with a 'Current year' button. In MUI4 clicking this button would automatically clause the calendar popup, however in MUI5 this is no longer the case.

Tests that could not be fixed

Two tests have been Istanbul ignored in order to get the build passing. These are:

  1. AdminContainer
  2. MyIncompleteRecord

Despite many hours attempting to find a resolution to the Jest errors both produced no solution could be found, and so their tests have been ignored for now. A ticket has been created to revisit this situation at a later date.

CKEditor

The Rich Editor is implemented with CKEditor. This is installed with npm modules. Case Change is a premium feature (fees involved) since v41, but because we are using a free version of the Change Case plugin, we had to build from source

If changes to ckeditor are required, these are sample commands:

 cd custom_modules/ckeditor5-custom-build/ # change into the modules subdirectory
 npm ci # install modules from package-lock file
 npm run build # after your changes, create the build files that our react app will pull in - MANDATORY!!
 # commit changes (including /build directory!!)
 cd ../../

We don't seem to need to issue any ci or run build commands for non-ckeditor localhost development, when not making changes to ckeditor - react picks up the build directory.

CKeditor says all the @ckeditor/ckeditor5- packages should have the same version (although there are a short number of exceptions).
