Swup Base Plugin

Base class for creating swup plugins.

Creating a Plugin

To create a new plugin, use the official swup plugin template. It comes with detailed instructions and the required tooling.

Usage

Import the base class and extend your plugin from it.

import Plugin from '@swup/plugin';

export default class PluginName extends Plugin {
  name = 'PluginName';
  mount() {}
  unmount() {}
}

Development

The official swup command-line interface has commands to help with bundling and linting plugins.

npm install --save-dev @swup/cli

Bundling

Bundle the plugin for production using microbundle, creating ESM and UMD builds.

# Bundle and transpile plugin code for distribution
swup package:bundle

# Bundle plugin code in watch mode
swup package:dev

Linting & formatting

Lint the plugin code using prettier and swup's recommended rules.

# Lint plugin code
swup package:lint

# Fix and format any lint errors
swup package:format

Package info

Check that the plugin's package.json file contains the required information for microbundle: input, output, export map, amd name, etc.

# Check plugin package info
swup package:check
