https://linear.app/unleash/issue/2-1232/implement-first-iteration-of-the-new-slack-app-addon
This PR implements the first iteration of the new Slack App addon.
Unlike the old Slack addon, this one uses a Slack App (bot) that is
installed to Slack workspaces in order to post messages. This uses
`@slack/web-api`, which internally uses the latest Slack API endpoints
like `postMessage`.
This is currently behind a flag: `slackAppAddon`.
The current flow is that the Unleash Slack App is installed from
whatever source:
- Unleash addons page;
- Direct link;
- https://unleash-slack-app.vercel.app/ (temporary URL);
- Slack App Directory (in the future);
- Etc;
After installed, we resolve the authorization to an `access_token` that
the user can paste into the Unleash Slack App addon configuration form.

This PR lays most of the groundwork required for emitting events when
features are marked as potentially stale by Unleash. It does **not**
emit any events just yet. The summary is:
- periodically look for features that are potentially stale and mark
them (set to run every 10 seconds for now; can be changed)
- when features are updated, if the update data contains changes to the
feature's type or createdAt date, also update the potentially stale
status.
It is currently about 220 lines of tests and about 100 lines of
application code (primarily db migration and two new methods on the
IFeatureToggleStore interface).
The reason I wanted to put this into a single PR (instead of just the db
migration, then just the potentially stale marking, then the update
logic) is:
If users get the db migration first, but not the rest of the update
logic until the events are fired, then they could get a bunch of new
events for features that should have been marked as potentially stale
several days/weeks/months ago. That seemed undesirable to me, so I
decided to bunch those changes together. Of course, I'd be happy to
break it into smaller parts.
## Rules
A toggle will be marked as potentially stale iff:
- it is not already stale
- its createdAt date is older than its feature type's expected lifetime
would dictate
## Migration
The migration adds a new `potentially_stale` column to the features
table and sets this to true for any toggles that have exceeded their
expected lifetime and that have not already been marked as `stale`.
## Discussion
### The `currentTime` parameter of `markPotentiallyStaleFeatures`
The `markPotentiallyStaleFetaures` method takes an optional
`currentTime` parameter. This was added to make it easier to test (so
you can test "into the future"), but it's not used in the application.
We can rewrite the tests to instead update feature toggles manually, but
that wouldn't test the actual marking method. Happy to discuss.
Highlight edge in the first paragraph.
Not sure if we should suggest that it should be the preferred choice,
but at least this helps to realize there's an alternative already in the
first paragraph.

## About the changes
Custom activation strategies are still the recommended way to go in our
documentation, but now most of the use cases for custom activation
strategies can be covered by strategy constraints (released with Unleash
4.16)
With this change, we try to drive people to use strategy constraints.

### What
We had a customer wonder why `/api/proxy/development` wasn't configured
for them. After some digging it was found that they'd followed our
documentation and assumed that the proxy was configured for them.
However, since we no longer host proxies, this was not the case. This PR
updates the documentation to point out that "Unleash hosts everything"
now means that our clients should use Frontend API keys and the
`/api/frontend` endpoint to get what they used to get from embedded
proxies.
## Missing
We should make a new illustration in the same vein as the other
illustrations on this page to demonstrate what the Frontend API really
is. This PR removes the reference to the picture of the topology of
having Unleash hosting proxies.

## About the changes
- Adding descriptions and examples to tag and tag types schemas
- Adding standard errors, summaries, and descriptions to tag and tag
types endpoints
- Some improvements on compilation errors

Make each error class have to define its own status code. This makes
it easier for developers to see which code an error corresponds to and
means less jumping back and forth between files. In other words:
improved locality.
Unfortunately, the long switch needs to stay in case we get errors
thrown that aren't of the Unleash Error type, but we can move it to
the `fromLegacyError` file instead.
Tradeoff analysis by @kwasniew:
+ I like the locality of error to code reasoning
- now HTTP leaks to the non-HTTP code that throws those errors e.g. application services
If we had other delivery mechanisms other than HTTP then it wouldn't make sense to couple error codes to one protocol (HTTP). But since we're mostly doing web it may not be a problem.
@thomasheartman's response:
This is a good point and something I hadn't considered. The same data was always available on those errors (by using the same property), I've just made the declaration local to each error instead of something that the parent class handles. The idea was to make it easier to create new error classes with their corresponding error codes. Because the errors are intended to be API errors (or at least, I've always considered them to be that), I think that makes sense.
Taking your comment into consideration, I still think it's the right thing to do, but I'm not bullish about it. We could always walk it back later if we find that it's not appropriate. The old code is still available and we could easily enough roll back this change if we find that we want to decouple it later.
## About the changes
Include a new configuration parameter to be able to specify
source_type_name. This is an opt-in feature which provides backward
compatibility to our existing users.
Closes#4109
## Discussion points
Maybe this should be hardcoded to `Unleash` but this gives additional
flexibility

In some of the places we used `NoAccessError` for permissions, other
places we used it for a more generic 403 error with a different
message. This refactoring splits the error type into two distinct
types instead to make the error messages more consistent.
### What
Adds a quick and dirty description to requestPerSeconds and
segmentedRequestPerSecondsSchema so the enterprise /rps endpoint has
better API docs.

This PR fixes an issue where events generated during a db transaction
would get published before the transaction was complete. This caused
errors in some of our services that expected the data to be stored
before the transaction had been commited. Refer to [linear issue
1-1049](https://linear.app/unleash/issue/1-1049/event-emitter-should-emit-events-after-db-transaction-is-commited-not)
for more info.
Fixes 1-1049.
## Changes
The most important change here is that the `eventStore` no longer emits
events when they happen (because that can be in the middle of a
transaction). Instead, events are stored with a new `announced` column.
The new event announcer service runs on a schedule (every second) and
publishes any new events that have not been published.
Parts of the code have largely been lifted from the
`client-application-store`, which uses a similar logic.
I have kept the emitting of the event within the event store because a
lot of other services listen to events from this store, so removing that
would require a large rewrite. It's something we could look into down
the line, but it seems like too much of a change to do right now.
## Discussion
### Terminology:
Published vs announced? We should settle on one or the other. Announced
is consistent with the client-application store, but published sounds
more fitting for events.
### Publishing and marking events as published
The current implementation fetches all events that haven't been marked
as announced, sets them as announced, and then emits them. It's possible
that Unleash would crash in the interim or something else might happen,
causing the events not to get published. Maybe it would make sense to
just fetch the events and only mark them as published after the
announcement? On the other hand, that might get us into other problems.
Any thoughts on this would be much appreciated.
