vir-line

An assembly line or pipeline that automatically aggregates each of its stages into a final state object type and supports scoped state listeners.

Demo

Usage

Here's a simple example that defines a stage, constructs and then starts a VirLine instance. See the TypeScript types for further options.

Each stage is intended to directly mutate the state object that it is given.

import {VirLine, VirLineStage} from 'vir-line';

const countStage = new VirLineStage<{count: number}>(
    {
        name: 'counter',
    },
    ({state}) => {
        state.count++;
    },
);

const virLine = new VirLine(
    [
        countStage,
    ],
    {
        count: 0,
    },
);

virLine.startUpdateLoop();
