Information

This is a monorepo project, please check packages

Devtools

There's some experimental devtools support starting from 1.0.0-beta.6, only available for vue-next and devtools beta 6.

Install plugin

To use devtools you need to install the plugin first:

import { createApp } from "vue";
import { VueComposableDevtools } from "vue-composable";
import App from "./App.vue";

const app = createApp(App);
app.use(VueComposableDevtools);
// or
app.use(VueComposableDevtools, {
  id: "vue-composable",
  label: "devtool composables"
});

app.mount("#app");

Component State

To add properties to the component inspector tab ComponentState

const bar = "bar";
useDevtoolsComponentState(
  {
    bar
  },
  {
    type: "custom composable" // change group
  }
);

const baz = () => "baz";
useDevtoolsComponentState({ baz });
// no duplicates added by default
useDevtoolsComponentState({ baz });

const the = 42;
useDevtoolsComponentState({ the });
// to allow multiple same key
useDevtoolsComponentState({ the }, { duplicate: true });

// use a devtools api list directly
interface StateBase {
  key: string;
  value: any;
  editable: boolean;
  objectType?: "ref" | "reactive" | "computed" | "other";
  raw?: string;
  type?: string;
}
useDevtoolsComponentState([
  {
    key: "_bar",
    type: "direct",
    value: "bar",
    editable: true
  },
  {
    key: "_baz",
    type: "direct",
    value: "baz",
    editable: false
  }
]);

// raw change
useDevtoolsComponentState((payload, ctx) => {
  payload.state.push(
    ...[
      {
        key: "_bar",
        type: "raw",
        value: "bar",
        editable: true
      },
      {
        key: "_baz",
        type: "raw",
        value: "baz",
        editable: false
      }
    ]
  );
});

Timeline events

To add timeline events:

const id = "vue-composable";
const label = "Test events";
const color = 0x92a2bf;

const { addEvent, pushEvent } = useDevtoolsTimelineLayer(
  id,
  description,
  color
);

// adds event to a specific point in the timeline
addEvent({
  time: Date.now(),
  data: {
    // data object
  },
  meta: {
    // meta object
  }
});

// adds event with `time: Date.now()`
pushEvent({
  data: {
    // data object
  },
  meta: {
    // meta object
  }
});

Inspector

Allows to create a new inspector for your data.

I'm still experimenting on how to expose this API on a composable, this will likely to change in the future, suggestions are welcome.

useDevtoolsInspector(
  {
    id: "vue-composable",
    label: "test vue-composable"
  },
  // list of nodes, this can be reactive
  [
    {
      id: "test",
      label: "test - vue-composable",
      depth: 0,
      state: {
        composable: [
          {
            editable: false,
            key: "count",
            objectType: "Ref",
            type: "setup",
            value: myRefValue
          }
        ]
      }
    }
  ]
);

Typescript

Typescript@3.x is not supported, the supported version can be checked on package.json, usually is the latest version or the same major as vue-3

Contributing

You can contribute raising issues and by helping out with code.

Tests and Documentation are the most important things for me, because good documentation is really useful!

I really appreciate some tweaks or changes on how the documentation is displayed and how to make it easier to read.
