Seed element
A starting point for creating reusable Polymer elements with built-in tooling support.
What is Seed element?
Seed Element is a boilerplate template for creating reusable Polymer elements, providing a structured starting point with built-in tooling for development, linting, and testing. It solves the problem of setting up a consistent and efficient workflow for building custom web components, reducing initial configuration overhead.
Frontend developers and teams building reusable UI components with Polymer who want a standardized, tooling-integrated foundation to accelerate development.
Developers choose Seed Element because it offers a minimal, opinionated setup with Polymer-specific best practices, integrated testing and linting tools, and support for Yeoman scaffolding, ensuring a smooth start for web component projects.
Overview
Polymer element boilerplate
Use Cases
Best For
- Quickly scaffolding new Polymer elements with consistent structure
- Setting up a development environment with Polymer-specific linting and testing
- Learning Polymer web component development with a ready-to-use template
- Integrating Yeoman for automated Polymer project generation
- Ensuring best practices in custom element dependency management
- Running cross-browser tests for Polymer elements using web-component-tester
Not Ideal For
- Projects using modern JavaScript frameworks like React or Vue instead of Polymer
- Teams that have standardized on npm or yarn for dependency management and avoid Bower
- Applications requiring extensive server-side rendering or SEO optimization where web components may introduce complexity
- Developers looking for pre-designed, styled UI components without custom development work
Pros & Cons
Pros
Includes Polylint for linting and Polyserve for local development, streamlining Polymer-specific workflows as per the README's setup instructions.
Supports automated project generation via the official generator-polymer, making it easy to start new elements with consistent structure.
Compatible with web-component-tester for cross-browser testing, allowing developers to run tests across multiple browsers as detailed in the README.
Provides a structured template that encourages consistency and maintainability, reducing initial configuration overhead for Polymer development.
Cons
Relies on Bower, which is largely obsolete in modern JavaScript ecosystems, requiring extra setup and potential compatibility issues with newer tools.
Tools like Polylint and Polyserve may not be actively maintained, limiting support for newer Polymer versions or features and increasing maintenance burden.
Tightly coupled with the Polymer library, making it unsuitable for projects that might transition to other web component libraries or frameworks without significant rework.
