Harlem Core

This is the core harlem package. Head over to harlemjs.com to get started or take a look at the demo to see it in action.

Getting Started

Getting started with Harlem is easy. Just follow the steps below and you'll be up and running in no time.

Installation

Install @harlem/core and any plugins/extensions you wish to include.

# yarn
yarn add @harlem/core

# npm
npm install @harlem/core

Register the Harlem Vue plugin

Register the Harlem plugin with your Vue app instance:

import App from './app.vue';

import {
    createVuePLugin
} from '@harlem/core';

createApp(App)
    .use(createVuePlugin())
    .mount('#app');

Create your first store

Create your store and define any getters, actions or mutations:

import {
    createStore
} from '@harlem/core';

// The initial state for this store
const STATE = {
    firstName: 'John',
    lastName: 'Smith'
};

// Create the store, specifying the name and intial state
export const {
    state, 
    getter,
    mutation,
    action,
    ...store
} = createStore('user', STATE);

export const fullName = getter('fullname', state => `${state.firstName} ${state.lastName}`);

export const setFirstName = mutation('set-first-name', (state, payload: string) => {
    state.firstName = payload;
});

export const setLastName = mutation('set-last-name', (state, payload: string) => {
    state.lastName = payload;
});

export const loadDetails = action('load-details', async (id: string, mutate) => {
    const response = await fetch(`/api/details/${id}`);
    const details = await response.json();

    mutate(state => {
        state.details = details;
    });
});

Use your store in your app

To use your store in your app just import the parts of it you need.

<template>
    <div class="app">
        <h1>Hello {{ fullName }}</h1>
        <button @click="loadDetails()">Load Details</button>
        <input type="text" v-model="firstName" placeholder="First name">
        <input type="text" v-model="lastName" placeholder="Last name">
    </div>
</template>

<script lang="ts" setup>
import {
    computed
} from 'vue';

import {
    state,
    fullName,
    setFirstName,
    setLastName,
    loadDetails
} from './stores/user';

const firstName = computed({
    get: () => state.firstName,
    set: value => setFirstName(value)
});

const lastName = computed({
    get: () => state.lastName,
    set: value => setLastName(value)
});
</script>
