Combine javascript functions and bash commands in your node scripts. Every task will be displayed with a spinner in the command line.

const fs = require("fs")
const path = require("path")
const { makeRunnable, exec, run } = require("./index.js")

makeRunnable(async () => {
    await run(createGitRepo, "Create git repository")

    await run(removeGitRepo, "Remove git repository")
})()

async function createGitRepo() {
    await exec("git init")
}

async function removeGitRepo() {
    fs.rmdirSync(path.join(__dirname, "..", ".git"), { recursive: true })
}

Installation

npm install @m.moelter/task-runner

Usage

The exec function is used to execute bash commands and run will execute an async function. Create your tasks using async functions, use exec inside them and run them using run. makeRunnable should be called in your script's main file and execute all of your tasks. If your scripts are big enough you may encapsulate every task in it's own file.

API

exec

Executes the given command(s) using node's integrated require("child_process").exec function.

exec(commands, [options])

await exec([
    "git add .",
    "git commit -m \"my commit message\"",
    "git push"
], { skipErrors: true })
