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

@synergy-design-system/vue

This package provides vue.js wrappers for Synergy Web Components.

It aims to provide an improved developer experience in Vue applications:

  • Provides two way data binding and v-model
  • Autocompletion and Types
  • Better custom event handling of synergy events

Known issues and limitations

Got any problems using our Vue wrappers? Please take a look at our list of known issues and limitations before creating a ticket.

Getting started

1. Package installation

Run the following steps to install the required packages.

# Install the base library and required css files
npm install --save @synergy-design-system/vue @synergy-design-system/tokens

# Optional: Install the styles utility package
npm install --save @synergy-design-system/styles

# Optional: if icons shall be used, install the assets package
npm install --save @synergy-design-system/assets

⚠️ Note we do not ship Vue in this package. You will have to install it by yourself first!

2. Add the desired theme to your application

The components will not display correctly without the needed theme. Please include either light or dark theme in your application, for example in a newly installed Vue application:

// src/main.ts
// Add this line to enable the light theme for your application
import "@synergy-design-system/tokens/themes/light.css";
import "@synergy-design-system/components/index.css";

// Optional: Import the styles package
import "@synergy-design-system/styles/index.css";

import { createApp } from "vue";
import App from "./App.vue";

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

3. Importing and rendering components

You may now use the components by importing them from the @synergy-design-system/vue package and rendering them in your own Vue components.

<script setup lang="ts">
  // Note the name includes Vue here.
  // This is done because it would
  // clash with our native components otherwise
  import { SynVueButton } from "@synergy-design-system/vue";
</script>

<template>
  <SynVueButton type="submit"> Submit me </SynVueButton>
</template>

4. Usage of the components

All information about which components exist as well as the available properties, events and usage of a component, can be found at components in our documentation. The documentation is written for no specific web framework but only vanilla html and javascript.

An example demo repository with the usage of the Vue wrapper components can be found here.

The naming of the components for Vue changes from kebab-case to PascalCase with an appended Vue after the syn. syn-button becomes SynVueButton:

<!-- Webcomponents example -->
<syn-button> My Button </syn-button>
<!-- Vue wrapper example -->
<SynVueButton> My Button </SynVueButton>

5. Usage of attributes

The attribute naming of the components are the same as in the documentation.

<!-- Webcomponents example -->
<syn-input
  label="Nickname"
  help-text="What would you like people to call you?"
  required
></syn-input>
<!-- Vue wrapper example -->
<SynVueInput
  label="Nickname"
  help-text="What would you like people to call you?"
  required
/>

6. Usage of events

Custom events are named in the documentation as following: syn-change, syn-clear, ... They stay the same for the Vue components:

<SynVueButton
  @syn-blur="handleBlur"
  @syn-focus="handleFocus"
  @syn-invalid="handleInvalid"
>
  My Button
</SynVueButton>

If typescript is used, you can get the correct types for components and events from the @synergy-design-system/components package.

An example for how these types can be used in case of event handling, is shown below:

<script setup lang="ts">
  import { SynVueInput } from "@synergy-design-system/vue";
  import type {
    SynChangeEvent,
    SynInput,
  } from "@synergy-design-system/components";

  const synChange = (e: SynChangeEvent) => {
    const input = e.target as SynInput;
    // Now we get access to all properties, methods etc. of the syn-input
    const surname = input.value;
    doSomething(surname);
  };
</script>

<template>
  <SynVueInput label="Surname" @syn-change="synChange" />
</template>

7. Obtaining a reference to the underlying native element (e.g. for usage of methods)

Sometimes, there is a need to interact directly with the underlying native web-component. For this reason, the library exposes a nativeElement property for all vue components.

<script setup lang="ts">
  import { SynVueInput, SynVueButton } from "@synergy-design-system/vue";
  import { ref } from "vue";

  const count = ref<InstanceType<typeof SynVueInput> | null>(null);

  const handleClick = () => {
    // Increment the count via calling the method
    count.value?.nativeElement?.stepUp();
  };
</script>

<template>
  <SynVueInput ref="count" label="My count" type="number" value="5" />
  <SynVueButton @click="handleClick"> Increment </SynVueButton>
</template>

8. Using two way databinding

We support Vue two way data binding for form components out of the box. You may use it in one of the following ways:

<script setup lang="ts">
  import { ref } from "vue";
  import {
    SynVueButton,
    SynVueCheckbox,
    SynVueTextarea,
    SynVueInput,
  } from "@synergy-design-system/vue";

  const formValues = ref({
    checkboxValue: false,
    inputValue: "",
    textAreaValue: "",
  });

  const submit = (e: Event) => {
    e.preventDefault();
    e.stopPropagation();
    const target = e.target as HTMLFormElement;

    const isValid = target.reportValidity();
    if (isValid) {
      const data = [...new FormData(target)]
        .map(v => {
          return `${v[0]}: ${v[1]}`;
        })
        .join(",\n")
        .trim();
      // Do something with the data
      console.log(data);
    }
  };
</script>

<template>
  <form @submit="submit">
    <SynVueInput
      label="Input Example"
      name="inputValue"
      required
      v-model="formValues.inputValue"
    />
    <SynVueTextarea v-model="formValues.textAreaValue" name="textAreaValue" />
    <SynVueCheckbox
      v-model="formValues.checkboxValue"
      required
      name="checkboxValue"
      >Agree</SynVueCheckbox
    >
    >
  </form>
</template>

Development

To create a new version of this package, proceed in the following way:

  1. Check out the Synergy Design System Repository.
  2. Run pnpm i -r to install all dependencies.
  3. Build the @synergy-design-system/components package (or run pnpm build in the project root to build everything).
  4. Move to to packages/_private/vue-demo and use pnpm start to spin up a local vite project using Vue and typescript to validate the build.

⚠️ The build process will always try to sync this packages package.json.version field with the latest version from @synergy-design-system/components! Therefore, it is best to not alter the version string
