feat(angular): setting props on a signal works (#29453)
Issue number: resolves #28876 --------- <!-- Please do not submit updates to dependencies unless it fixes an issue. --> <!-- Please try to limit your pull request to one type (bugfix, feature, etc). Submit multiple pull requests if needed. --> ## What is the current behavior? <!-- Please describe the current behavior that you are modifying. --> When assigning `componentProps` as inputs to an Angular component, we do `Object.assign`. When using the newer Angular Signals API for inputs the value of an input is a function: ```js myInput = input<string>('foo') // this is a function ``` The developer accesses the value of `myInput` in a template by doing `myInput()` since `myInput` is a function. If a developer passes `componentProps: { myInput: 'bar' }` then the value of `myInput` is set to this string value, overriding the function. As a result, calling `myInput()` results in an error because `myInput` is a string not a function. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> - Angular 14.1 introduced `setInput` which lets us hand off setting inputs to Angular. This will set input values properly even when using a Signals-based input. ## Does this introduce a breaking change? - [x] Yes - [ ] No <!-- If this introduces a breaking change: 1. Describe the impact and migration path for existing applications below. 2. Update the BREAKING.md file with the breaking change. 3. Add "BREAKING CHANGE: [...]" to the commit description when merging. See https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#footer for more information. --> As part of this `NavParams` has been deprecated as it is incompatible with the `setInput` API. The old `Object.assign` worked to allow devs to get all of the `componentProp` key value pairs via `NavParams` even if they are not defined as `Inputs`. Using `setInput` will now throw an error, so developers need to create an `@Input` for each parameter. This means that `NavParams` has no purpose and can safely be retired in favor of Angular's Input API. Not removing NavParms would make it difficult for us to support new Angular APIs such as this Signals-based input API. ## Other information <!-- Any other information that is important to this PR such as screenshots of how the component looks before and after the change. --> Dev build: `8.1.1-dev.11715021973.16675b67` You will need to update the Ionic config to opt-in to the new option: ```ts useSetInputAPI: true, ``` --------- Co-authored-by: Liam DeBeasi <[email protected]>
