Usage

Examples

your own library:

Commander.js

import { PluginCommand } from 'commander-plugin-system';

const loader = new PluginLoader(/* strategy */);
const enhancer = new PluginEnhancer(/* strategy */);

const plugins = loader.run();

const enhancedProgram = enhancer.enhance(program, plugins);

//option 1
export { enhancedProgram as program };
//option 2
enhancedProgram.parseArgs();

//* your base program */
program.addCommand(new PluginCommand());

express.js:

...

defining plugins:

commonjs:

module.exports = [
    {
        name: 'exported plugin',
    },
];

please note the syntax (an array of objects) the array is only required for module.exports syntax ( and even for just one plugin)

es modules (preferred)

//plugin.[j|t]s

// single plugin
export const myPlugin = {
    ...props,
};

//multi plugins:
export const myPlugins = [
    {
        ...plugin,
    },
    {
        ...plugin2,
    },
    {
        ...plugin3,
    },
];
