Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Changed

  • Update valueBinding() to automatically parse the passed model value to String

[1.0.0-alpha.35] - 2022-11-02

Breaking

Highlights of breaking changes from the log further down:

Namespace $element bindings on component refs

To avoid child component props to clash with DOM bindings when using a reserved binding name the new $element namespace was created. Inside you'll have access to the ref component element bindings, and outside the component props are available.

  setup({ refs }) {
    return [
      bind(refs.child, {
         // component prop
        style: computed(() => 'some-value'),
        // element bindings
        $element: {
          style: computed(() => { 'font-weight': 400 }),
        }
      }),
    ];
  },

If you have a component that is accessing the child component's element bindings, you'll need to move those bindings inside the $element namespace

Highlights

New and exciting additions from the log further down:

New custom prop type source

If you need to extract a value not supported by the other source types you can use the new custom source

defineComponent({
  name: 'my-component',
  refs: { title: 'title' },
  props: {
    // grab the length of the title component.
    // outputs "32" (as a number)
    characterCount: propType.number.source({ 
      target: 'title',
      type: 'custom', 
      options: {
        // function used for extracting the value
        customSource: (element: HTMLElement | Array<HTMLElement> | undefined) =>
          (element as HTMLElement)!.innerHTML.length;
      }
    })
  },
})
<div data-component="my-component">
  <h1 data-ref="title">This title is 32 characters long</h1>
</div>

See the docs for propType source for more details.

New form source for extracting values from inputs

For extraction of initial input values you can use the new form source

defineComponent({
  name: 'my-component',
  refs: {
    email: 'email',
  },
  props: {
    // get the value from the email ref
    // outputs "[email protected]"
    email: propType.string.source(
      { target: 'email', type: 'form'},
    ),
  },
})
<div data-component="my-component">
  <input type="text" data-ref="email" value="[email protected]"/>
</div>

See the docs for propType source for more details.

[1.0.0-alpha.31] - 2022-02-28

Breaking

Highlights of breaking changes from the log further down:

Simplify usage of lazy components

In order to use components as lazy, they had to be exported with the supportLazy helper. This is not needed anymore. The lazy function now determines the export based on the displayName (1st parameter), which should match the export based on convention. If you follow this convention for your components, you don't have to change anything.

If you had a webpackExports: lazy comment in your import statement (as was previously recommended in the docs and examples), this can be removed.

If your component export doesn't match the convention, you can provide the exportName (3rd parameter).

See the docs for lazy for more details.

Only allow passing reactive values to component props in bindings

Previously you could pass non-reactive values to component prop bindings. While this technically works, this is often not intended, and results in the unexpected behaviour of the component not receiving updated values. This change requires all bindings to component props to be reactive.

Even though this is technically a breaking change, any cases that will give an error after upgrading to this version, were probably mistakes in your existing code.

If you do have a need for static values in your bindings, you should now wrap them in a computed.

Two-way input bindings

Two-way bindings sync up the state between the component and the HTML. If the initial state of the two match up, there is nothing to do here. But if the initial state is different (e.g. a ref has true, but html has false), the binding code doesn't know what to do.

By default, it still picks the HTML as the initial source, but a warning is logged that they were not equal. To change this behaviour, or get rid of the warning, you can explicitly provide the source by setting the initialValueSource binding config to either html or binding.

See the docs for bindings for more details.

Make the props object parameter in the setup function readonly.

Previously it was possible to abuse the props objects that is passed in the setup function as internal component state. While this can work for extracted props, for the ones passed from parent components this could result in conflicts.

Since the data flow should be predictable, props should only flow from source (html or parent) to target (child), and should be immutable. This is why this object is now readonly. Both at runtime (will log an error) and in the type system.

If your code relies on this current behaviour, you should copy this state to an internal ref, and use that to read and write the value instead.

Improve control over bindTemplate rendering

The biggest change here is that the data and template properties are now merged into a single onUpdate function, that acts as a watchEffect. All usages of bindTemplate have to be updated.

Previously:

bindTemplate(
  refs.container,
  () => someData.value,
  (data) => data.map(renderTemplate),
);

Now:

bindTemplate(refs.container, () => someData.value.map(renderTemplate));

Read the docs on bindTemplate to understand when the optional onlyWach parameter from onUpdate can be used to improve performance in advanced use cases.

Additionally, the renderImmediate option has been changed to forceImmediateRender to indicate the new behaviour. Previously you would have to be explicit about when the bindTemplate should render immediately or not, while the new implementation does this based on the existence of any HTML inside the container. forceImmediateRender can override this behaviour.

Note: Previously, watch was used to watch for explicit changes to the passed computed. This would have been "shallow" by default, and other reactive data used in the template function would not trigger a rerender.

The new implementation uses watchEffect, which is triggered by any reactive updates in the onUpdate function, but also watches refs that have nested objects deeply by default.

To only update changes to the ref.value, a shallowRef can be used instead.

Added

  • Allow the .source() option of the propType. helper to receive an array of source configurations. The first hit will be used.
  • Add support for multiple components in refComponents – same as already was possible in refComponent
  • Proxy watch/watchEffect to allow auto-cleanup on component unmount – no need to clean these up yourself anymore.
  • Allow typing refs as SVGElement

Fixed

  • Fix usage of the css "string" binding.
  • Fix usage of multiple classes as key for the css "object" binding.
  • Fix issues with two-way input bindings.
  • Allow DOM bindings on components without props
  • Fix issue with queryRef where a nested element would be found and ignored

Changed

  • Simplify usage of lazy components.
  • Only allow passing reactive values to component props in bindings.
  • When two-way input bindings don't match between the html and the initial binding value, the initialValueSource binding config should be added to specify which source should be used.
  • Make the props object parameter in the setup function readonly.
  • Improve control over bindTemplate rendering.
  • Update @vue/reactivity and @vue/runtime-core to 3.2.31

Deprecated

  • Make the defaultValue on props actually do something, setting the value when no other "error" case is triggered.

Fixed

  • Fix incorrect invalid binding warnings, showing logs in the console that were not correct.
  • Prevent refs on collections to update when "inner" HTML updates, causing bindings to re-apply without cleanup.
