vue-apexstock

Vue 3 component wrapper for ApexStock — financial charting (candlesticks, indicators, drawing tools) built on top of ApexCharts.

A thin, typed wrapper around the imperative ApexStock class: it creates the instance on mount, forwards prop changes to update(), and tears it down on unmount.

Install

npm install vue-apexstock apexstock apexcharts

apexcharts, apexstock, and vue (3.x) are peer dependencies. ApexCharts must be available as a global, the same way the core library expects.

Usage

<script setup>
import { ref } from "vue";
import ApexStock from "vue-apexstock";

const options = { chart: { height: 420 }, theme: { mode: "light" } };
// New array identity on data change triggers an update.
const series = ref([{ name: "Price", data: [] }]);
</script>

<template>
  <ApexStock :options="options" :series="series" style="width: 100%" />
</template>

OHLC points use the ApexStock shape { x, y: [open, high, low, close], v }.

Props

| Prop | Type | Description | | --- | --- | --- | | options | StockChartOptions | Full chart options (the 2nd arg to new ApexStock). Required. | | series | StockChartOptions["series"] | Convenience: overrides options.series. |

Updates fire when the options or series identity changes (assign a new object/array). In-place mutation of the same object is intentionally not deep-watched, to avoid the cost of deep-watching large datasets.

Accessing the instance

<script setup>
import { ref } from "vue";
import ApexStock from "vue-apexstock";

const chart = ref();
const addRSI = () => chart.value?.getInstance()?.updateIndicator("rsi");
</script>

<template>
  <button @click="addRSI">Add RSI</button>
  <ApexStock ref="chart" :options="{ chart: { height: 400 }, series }" />
</template>

• getInstance() → the live ApexStock instance (call any method: update, updateIndicator, updateTheme, export, …), or null before mount.
• getElement() → the container <div>.

Live demo

A no-build demo lives in demo/: the real wrapper driving the real ApexStock core (the unit tests mock the core, this does not). It loads Vue from this package's node_modules (the ESM-browser build) and the core from the repo's dist/, so build both first and serve over a static server (no bundler needed):

npm install                  # in this package, for the Vue ESM build
npm run build                # build the wrapper -> dist/
(cd ../.. && npm run build)  # build the core -> dist/

# Serve from the apexcharts working dir (parent of this repo) so the sibling
# apexcharts-js checkout also resolves, then open the demo URL:
cd ../../.. && python3 -m http.server 8080
# http://localhost:8080/apexstock/packages/vue-apexstock/demo/

SSR

The component renders only a container <div> on the server; the chart is created in a client-only onMounted hook. (The core apexstock package is import-safe in Node, but rendering needs a DOM.)
