Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

vuex-composition-helpers

Codefresh build status

A util package to use Vuex with Composition API easily.

Installation

$ npm install vuex-composition-helpers

Basic Usage Examples

import { useState, useActions } from 'vuex-composition-helpers';

export default {
	props: {
		articleId: String
	},
	setup(props) {
		const { fetch } = useActions(['fetch']);
		const { article, comments } = useState(['article', 'comments']);
		fetch(props.articleId); // dispatch the "fetch" action

		return {
			// both are computed compositions for to the store
			article,
			comments
		}
	}
}

Namespaced Usage Examples

import { createNamespacedHelpers } from 'vuex-composition-helpers';
const { useState, useActions } = createNamespacedHelpers('articles'); // specific module name

export default {
	props: {
		articleId: String
	},
	setup(props) {
		const { fetch } = useActions(['fetch']);
		const { article, comments } = useState(['article', 'comments']);
		fetch(props.articleId); // dispatch the "fetch" action

		return {
			// both are computed compositions for to the store
			article,
			comments
		}
	}
}

You can also import your store from outside the component, and create the helpers outside of the setup method, for example:

import { createNamespacedHelpers } from 'vuex-composition-helpers';
import store from '../store'; // local store file
const { useState, useActions } = createNamespacedHelpers(store, 'articles'); // specific module name
const { fetch } = useActions(['fetch']);

export default {
	props: {
		articleId: String
	},
	setup(props) {
		const { article, comments } = useState(['article', 'comments']);
		fetch(props.articleId); // dispatch the "fetch" action

		return {
			// both are computed compositions for to the store
			article,
			comments
		}
	}
}

Typescript mappings

You can also supply typing information to each of the mapping functions to provide a fully typed mapping.

import { useState, useActions } from 'vuex-composition-helpers';

interface RootGetters extends GetterTree<any, any> {
	article: string;
	comments: string;
}

interface RootActions extends ActionTree<any, any> {
	fetch: (ctx: ActionContext<any, any>, payload: number);
}

export default {
	props: {
		articleId: String
	},
	setup(props) {
		const { fetch } = useActions<RootActions>(['fetch']);
		const { article, comments } = useGetters<RootGetters>(['article', 'comments']);
		fetch(props.articleId); // dispatch the "fetch" action

		return {
			// both are computed compositions for to the store
			article,
			comments
		}
	}
}

Advanced Usage Example

consider separate the store composition file from the store usage inside the component. i.g.:

// store-composition.js:
import { wrapStore } from 'vuex-composition-helpers';
import store from '@/store'; // local store file

export default wrapStore(store);
// my-component.vue:
import { createNamespacedHelpers } from './store-composition.js';
const { useState, useActions } = createNamespacedHelpers('articles'); // specific module name
const { fetch } = useActions(['fetch']);

export default {
	props: {
		articleId: String
	},
	setup(props) {
		const { article, comments } = useState(['article', 'comments']);
		fetch(props.articleId); // dispatch the "fetch" action

		return {
			// both are computed compositions for to the store
			article,
			comments
		}
	}
}

Enjoy!
