Plugins allow you to extend freesewing beyond the basic functionality. We have a list of available plugins. If you can’t find what you’re looking for, you can write your own plugin.

Types of plugins

Plugins come in two flavours:

  • Build-time plugins
  • Run-time plugins

When writing a plugin, ask yourself whether it’s a run-time or a build-time plugin. And if the answer is both, please split them into two plugins.

Run-time plugins

A plugin is a run-time plugin if it can be added by the user after instantiating your pattern.

Our theme plugin is a good example of a run-time plugin.

If it’s missing, your pattern will still work, it just won’t look pretty.

Run-time plugin are loaded at run time, by passing them to the Pattern constructor:

import Aaron from "@freesewing/aaron";
import theme from "@freesewing/plugin-theme";
import i18n from "@freesewing/plugin-i18n";

const myAaron = new Aaron()

Plugins that use only hooks are typically run-time plugins

Build-time plugins

A plugin is a build-time plugin if it is required by the pattern at build-time. In other words, if it’s a dependency for the pattern.

Our plugin bundle bundles build-time plugins that are used in many patterns. If they are missing, your pattern won’t load.

Build-time plugin are loaded at build time, by passing them to the freesewing.Design constructor:

import freesewing from "@freesewing/core";
import plugins from "@freesewing/plugin-bundle";
import config from "../config";

const Pattern = new freesewing.Design(config, plugins);

Plugins that provide a macro are typically build-time plugins
