The hostname strategy will not work correctly with the playground because it depends on external state. In its constructor, it tries to query the environment or use the os.hostname function to determine what its current hostname is. This means that no matter what the user does in the playground, they can’t affect the results of this strategy. It’s also unlikely that it will be true. And if it is, it probably won’t be true for their clients.
In theory, we could accept a hostname property on the Unleash context and use the provided hostname in the address. However, I’m afraid that it’ll make users think that they can impact the hostname strategy by setting the property on their context, when that doesn’t do anything outside of the playground. It would also make the playground evaluate things differently from a regular SDK and I’m not sure that that’s something we want.
Instead, this change to the API makes the feature evaluate to 'unknown' or `false` (depending on constraints).
* Feat: return reasons why a feature evaluated to true or false
Note: this is very rough and just straight ripped from the nodejs
client. It will need a lot of work, but is a good place to start
* Feat: add suggested shape for new payload
* Chore: minor cleanup
* Wip: make server compile again
* Remove unused schema ref
* Export new schemas
* Chore: fix some tests to use sub property
* Fix: fix some tests
* Refactor: rename some variables, uncomment some stuff
* Add segments type to bootstrap options
* Add segments capability to offline feature evaluator
* Fix function calls after turning params into an option abject
* Feat: test strategy order, etc
* Feat: add test to check that all strats are returned correctly
* Feat: allow you to include strategy ids in clients
* Wip: hook up segments in the offline client.
Note: compared to regular clients, they still fail
* Feat: add segments validation
* Fix: fix test case invariant.
* Chore: revert to returning only `boolean` from strategies.
This _should_ make it work with custom strategies too 🤞
* Feat: make more properties of the returned feature required
* Wip: add some comments and unfinished tests for edge cases
* Feat: add `isEnabledInCurrentEnvironment` prop
* Feat: consider more strategy failure cases

* Fix: fix issue where feature evaluation state was wrong
* Chore: update openapi spec
* Fix: fix broken offline client tests
* Refactor: move schemas into separate files
* Refactor: remove "reason" for incomplete evaluation.
The only instances where evaluation is incomplete is when we don't
know what the strategy is.
* Refactor: move unleash node client into test and dev dependencies

* Chore: remove a bunch of code that we don't use
* Chore: remove comment
* Chore: remove unused code
* Fix: fix some prettier errors
* Type parameters in strategies to avoid `any`
* Fix: remove commented out code
* Feat: make `id` required on playground strategies
* Chore: remove redundant type
* Fix: remove redundant if and fix fallback evaluation
* Refactor: reduce nesting and remove duplication
* Fix: remove unused helper function
* Refactor: type `parameters` as `unknown`
* Chore: remove redundant comment
* Refactor: move constraint code into a separate file
* Refactor: rename `unleash` -> `feature-evaluator`
* Rename class `Unleash` -> `FeatureEvaluator`
* Refactor: remove this.ready and sync logic from feature evaluator
* Refactor: remove unused code, rename config type
* Refactor: remove event emission from the Unleash client
* Remove unlistened-for events in feature evaluator
* Refactor: make offline client synchronous; remove code
* Fix: update openapi snapshot after adding required strategy ids
* Feat: change `strategies` format.
This commit changes the format of a playground feature's `strategies`
properties from a list of strategies to an object with properties
`result` and `data`. It looks a bit like this:
```ts
type Strategies = {
result: boolean | "unknown",
data: Strategy[]
}
```
The reason is that this allows us to avoid the breaking change that
was previously suggested in the PR:
`feature.isEnabled` used to be a straight boolean. Then, when we found
out we couldn't necessarily evaluate all strategies (custom strats are
hard!) we changed it to `boolean | 'unevaluated'`. However, this is
confusing on a few levels as the playground results are no longer the
same as the SDK would be, nor are they strictly boolean anymore.
This change reverts the `isEnabled` functionality to what it was
before (so it's always a mirror of what the SDK would show).
The equivalent of `feature.isEnabled === 'unevaluated'` now becomes
`feature.isEnabled && strategy.result === 'unknown'`.
* Fix: Fold long string descriptions over multiple lines.
* Fix: update snapshot after adding line breaks to descriptions
* Wip: fix openapi spec
* Feat: add openapi enforcer for enforcing the generated schema
* Chore: Allow the example keyword in params
* Feat: add validator tests and fix some errors
* Use @apidevtools/swagger-parser for schema validation
* Wip: refactor tests for updated schema name
* Feat: update request params creation method
* Feat: add query params to state
* Refactor: move mapping test into separate function
* Refactor: rename request-parameters -> query-parameters
* Refactor: expose only finished query parameters
* Wip: fixup param types
* Refactor: remove unused types
* Chore: rename and cleanup
* Chore: cleanup
* Fix: Update snapshot
* Fix: use ?? Instead of paramToBool to get defaults
* Wip: generate query param object type from openapi params list
* Wip: use generated types for export query params
* Revert "Fix: use ?? Instead of paramToBool to get defaults"
This reverts commit 842567500b.
Because we accept bools, strings, and numbers, this is the only way to
do it.
* Chore: update and pin json-schema-to-ts
* Fix: use `&` to merge types
* Update snapshot
* Chore: rename export-parameters-schema -> export-query-parameters
When it ends in `schema`, the tests expect it to be included in the
openapi index file.
