July 13th 2024 - ESBuild and asset caching improvements
We have recently introduced several enhancements to the ESBuild process to improve stability, logging, and basic type annotations. These are part of
Additionally, we have integrated a new and improved process for handling asset cache-busting. Previously, we appended a query string representing the build number or Git commit hash to our assets for cache-busting. With the recent introduction of ESBuild, we have implemented a more common asset-revving solution, using the hash of the asset in the asset's output filename, like /assets/js/app.UG7VY7MS.js.
In brief, this implementation creates a manifest.json file during the asset build process, which maps the original asset name to it's new rev'd name. We then use the assetMap filter, introduced as part of this PR, to match the original asset names to their hashed versions, like so
<script type="module" src="{{ '/assets/js/app.js' | assetMap }}"></script>

July 11th 2024 – Remove Typescript outdated checks
We originally added these checks to the template project to try to nudge people into performing major version updates rather than solely focusing on security patches. This has led to a lot of confusion and queries from teams asking why we're enforcing these draconian checks. Previously we added some guidance suggesting developers remove it but this was not generally read.
Rather than add to the complexity of the rewrite script we've decided to remove these checks entirely.

June 19th 2024 – Add ESBuild!
This is a bit of a WiP but rapidly speeds up the time to redeploy on changes. It does that by running typescript compiler in a side channel. It's worth adopting now but there are subsequent commits and changes that will continue to be integrated to improve this.

May 22nd 2024 – Remove prometheus metrics middleware and metrics app. We had discussed that very few teams actually go on to set up a dashboard to surface the information and tend to use application insights instead for the information. In addition it had also caused a memory leak and production issues (manifesting in increased 502 error rates) in at least two applications that had inherited from the template so it seems wise to remove this tooling by default.

May 10th 2024 – Derive user details from the authorization_code "user" token instead of making an API call to hmpps-manage-users-api, thereby removing an unnecessary dependency.

February 29th 2024 – Use same node version for outdated check and security scan. This currently defaults to node 16

February 15th 2024 – Move over to use Debian 12 based image (bookworm)

January 9th 2024 – Move over to Gov UK Frontend 5.0 and MoJ Frontend 2.0
Note, this removed support for IE8,9,10 etc.

November 29th 2023 – Remove getUserRoles as an api call and add as decoded from the token #274
This is to encourage services not to make additional calls to retrieve a user's role information. Usually roles are cached with the session meaning that the user has to log out and in again to bring in changes to roles - as user details are also cached this will not change this behaviour.

November 6th 2023 – Add HMPPS Manage Users API to health checks

October 27th 2023 – Update to 4.0.0 of jwt-decode module
This had breaking changes and required an update to the import statement

October 27th 2023 – Update application to use node.js version 20 and npm version 10
Application updated to node 20.8 along with one minor node module tweaks

October 25th 2023 – Replace deprecated HMPPS Auth API endpoints with calls to HMPPS Manage Users API
/api/user/me -> /users/me
/api/user/me/roles -> /users/me/roles

October 4th 2023 – Improve REST client and propagate user types into res.locals
The base REST client now supports GET, DELETE, PATCH, POST, PUT methods all allowing query parameters and generic response types.
The user object built by setUpCurrentUser middleware is exposed in res.locals of request handlers
preventing the need for type assertions.

September 28th 2023 - Add in environment name to the header
For dev and pre-prod we now display the environment name in the header to let people know that the service isn't production. This brings the template into line with the new micro frontend components header.
September 22nd 2023 - Ensure health/info endpoints are the same information as the Kotlin templates
As part of the work on the service catalogue we are trying to ensure all services and applications present standard /health and /info endpoints. As the Kotlin template is provided with a standard set of information as part of Spring Boot, it made sense to make sure the Typrscript template was made to match. This ensures these endpoints can be processed programmatically without needing to know what format the information is being presented.
For more details ask on the #hmpps-service-catalogue channel.

August 3rd 2023 - Add /info endpoint and expose product ids
As part of the work on the service catalogue we are giving all applications their own product id. This change adds a new info endpoint to expose this id in a consistent place.

June 9th 2023 - Do not retry POST requests by default
It's not safe to retry idempotent calls as this introduces the risk of creating multiple resources. This fix changes the default to not carry out any retries but allows switching on retrying if desired.

April 13th 2023 - Caching fix
Asset caching was only set to 20 seconds. This fix changes the default to 1 hour which has a profound effect on the number of requests the application serves.

There was an additional unnecessary build step as part of start:dev npm task. This more than doubled the start time on the initial run.

February 3rd 2023 - Revert multi build docker image
Multibuild docker images ended up taking a very long time after the upgrade to node 18 (1hr+). Some work needs to be done to move to support multi host builds in our circle orb, in the meantime we’ve removed this and are just building images solely for deployment.
