vue-sanitize

vue-sanitize

HTML sanitizer plugin for Vue 3, powered by sanitize-html.

Note Always sanitize user input on the server. Use this plugin only when client-side sanitization is genuinely needed (e.g. live markdown previews).

Install

npm install vue-sanitize
# or
yarn add vue-sanitize
# or
pnpm add vue-sanitize

Usage

Register the plugin

import { createApp } from "vue";
import VueSanitize from "vue-sanitize";
import App from "./App.vue";

createApp(App).use(VueSanitize).mount("#app");

You can pass default sanitize-html options:

import VueSanitize from "vue-sanitize";

const defaultOptions = {
  allowedTags: ["a", "b"],
  allowedAttributes: {
    a: ["href"],
  },
};

createApp(App).use(VueSanitize, defaultOptions).mount("#app");

Options API (this.$sanitize)

<template>
  <div contenteditable="true" @paste="onPaste" />
</template>

<script lang="ts">
import { defineComponent } from "vue";

export default defineComponent({
  methods: {
    onPaste(event: ClipboardEvent) {
      event.preventDefault();
      const html = this.$sanitize(event.clipboardData?.getData("text/html") ?? "");
      document.execCommand("insertHTML", false, html);
    },
  },
});
</script>

Composition API (useSanitize)

<script setup lang="ts">
import { useSanitize } from "vue-sanitize";

const sanitize = useSanitize();

function onPaste(event: ClipboardEvent) {
  event.preventDefault();
  const html = sanitize(event.clipboardData?.getData("text/html") ?? "", {
    allowedTags: ["b", "br"],
  });
  document.execCommand("insertHTML", false, html);
}
</script>

<template>
  <div contenteditable="true" @paste="onPaste" />
</template>

API

app.use(VueSanitize, defaultOptions?)

Registers the plugin. defaultOptions are forwarded to sanitize-html and used whenever a call site does not pass its own options. See the sanitize-html docs for the full option reference.

this.$sanitize(dirty, options?) / useSanitize()(dirty, options?)

Returns the sanitized HTML string.

defaults

Re-exports sanitizeHtml.defaults for inspection or extension.

import { defaults } from "vue-sanitize";
console.log(defaults.allowedTags);
