@knime/components

This project contains Vue components & composables, that can be used for the frontend of all KNIME web projects.

Demo

A demo of all contained UI components, icons, CSS colors etc. can be found here: https://knime.github.io/webapps-common/

Installation

To install the @knime/components package, you can use npm:

npm install @knime/components

Setup

SVG loading

Components use SVG files as Vue components. Therefore, you need to use the vite plugin vite-svg-loader in your vite.config.ts:

import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";

import svgLoader from "vite-svg-loader";
import { svgoConfig } from "@knime/styles/config/svgo.config";

export default defineConfig({
  plugins: [vue(), svgLoader({ svgoConfig })],
  // [...]
});

Usage

To use it in your project, you can import it as follows:

Components

import { DonutChart } from "@knime/components";

or import types as follow:

import type { MenuItem } from "@knime/components";

Composables

import { useClickOutside } from "@knime/components";

Vue

The Vue components expect that the app provides the following:

• Vue and Consola compatible to the versions defined in package.json
• global window.consola instance for logging

Nuxt

Additional requirements when used with Nuxt:

• Nuxt-native ClientOnly and NuxtLink components need to be registered globally, otherwise they can't get resolved in src/components/nuxtComponentResolver.ts

Stacking order and z-index

Try to avoid setting z-indices since they can lead to stacking conflicts, especially when shared components are used in many different apps. Many times a z-index is not needed, e.g. elements which use position: absolute; are stacked on top anyway. Additionally, the local stacking order can be controlled by changing the order in the DOM or using ::after instead of ::before pseudo elements.

When the above doesn’t work and you need a z-index, think about

• if you just want to stack things locally. If yes, set isolation: isolate; on the parent element so you don’t pollute the global stacking context.
• if it needs to be in the global context and the code you’re editing is in webapps-common, use a CSS variable with default like z-index: var(--z-index-common-modal, 100); so our apps can overwrite it if needed. To see which are available in the shared components, search for --z-index-common- in this repository.
