The current updateContent JS replaces the in-page
HTML with the HTML from the server the first time
an AJAX request is fired, even if the HTML from
the server has no changes. This is because the
code that compares the two operates on two
different things:
The HTML in the page is the component HTML, with
all the data attributes and the partial HTML
(marked with the 'ajax-block-container' class) as
its first child:
```
<div data-module="update-content" data-url="...">
<div class="ajax-block-container">
...
</div>
</div>
```
The HTML from the server only contains the
partial:
```
<div class="ajax-block-container">
...
</div>
```
The diffing code just sees them as different at
the top level so replaces the page HTML with the
partial from the server. This means all subsequent
diffs are between partial HTML and partial HTML so
only update on actual changes.
These replace the component with the partial, as
part of the component initialising. This means all
code that runs on an AJAX response will only
compare like-for-like so will result in actual
changes (or none at all), not just swapping one
element out for another.
Note: this commit also removes the
aria-live="polite" from the ajax_block component.
It has always been overwritten by the first
response so never announces anything to assistive
technologies. Removing it makes this more clear.

Setting up
Python version
At the moment we run Python 3.9 in production.
NPM packages
brew install node
NPM is Node's package management tool. n is a tool for managing different versions of Node. The following installs n and uses the long term support (LTS) version of Node.
npm install -g n
n lts
environment.sh
In the root directory of the application, run:
echo "
export NOTIFY_ENVIRONMENT='development'
export FLASK_APP=application.py
export FLASK_ENV=development
export WERKZEUG_DEBUG_PIN=off
"> environment.sh
AWS credentials
To run parts of the app, such as uploading letters, you will need appropriate AWS credentials. See the Wiki for more details.
To run the application
# install dependencies, etc.
make bootstrap
# run the web app
make run-flask
Then visit localhost:6012.
Any Python code changes you make should be picked up automatically in development. If you're developing JavaScript code, run npm run watch to achieve the same.
To test the application
# install dependencies, etc.
make bootstrap
# run all the tests
make test
# continuously run js tests
npm run test-watch
To run a specific JavaScript test, you'll need to copy the full command from package.json.
