Listr Smart Renderer

A renderer for Listr & listr2 that handles extremely long lists of tasks by collapsing into a summary view.

Pass in maxFullTasks to tell the renderer when to collapse into summary view. The summary outputs one line for each task that is currently being executed, one line for each task that fails and a final summary line.

Heavily based on listr-update-renderer, with all the same nice UI features.

Install

npm install @tryghost/listr-smart-renderer --save

or

yarn add @tryghost/listr-smart-renderer

Usage

// Either of these 2 will work
import Listr from 'listr';
import {Listr} from 'listr2';
import SmartRenderer from '@tryghost/listr-smart-renderer';

const list = new Listr([
    {
        title: 'foo',
        task: () => Promise.resolve('bar')
    }
], {
    renderer: SmartRenderer,
	maxFullTasks: 10
});

list.run();

This package also exports a makeTaskRunner method that simplifies your script. listr2 is used here.

import {makeTaskRunner} from '@tryghost/listr-smart-renderer';

let tasks = [
    {
        title: 'Do some thing',
        task: async (ctx) => {
            // Things here
        }
    },
    {
        title: 'Do more thing',
        task: async (ctx) => {
            // more here
        }
    }
];

let taskRunner = makeTaskRunner(tasks);

await taskRunner.run();
