With listr one can define a set of tasks to run:

const execa = require("execa");
const Listr = require("listr");

const tasks = new Listr([
    {
        title: "Git",
        task: () => {
            return new Listr([
                {
                    title: "Checking git status",
                    task: () => execa.stdout("git', ['status', '--porcelain"]).then(result => {
                        if (result !== "") {
                            throw new Error("Unclean working tree. Commit or stash changes first.");
                        }
                    })
                },
                {
                    title: "Checking remote history",
                    task: () => execa.stdout("git", ["rev-list", "--count", "--left-only", "@{u}...HEAD"]).then(result => {
                        if (result !== "0") {
                            throw new Error("Remote history differ. Please pull changes.");
                        }
                    })
                }
            ], {concurrent: true});
        }
    },
    {
        title: "Install package dependencies",
        task: () => execa("npm", ["install"])
    },
    {
        title: "Run tests",
        task: () => execa("npm", ["test"])
    },
    {
        title: "Publish package",
        task: () => execa("npm", ["publish"])
    }
]);

tasks.run().catch(err => {
    console.error(err);
});

It’s also possible to dynamically skip a task in the series, and to run tasks concurrently.

A standalone binary to pass in a .json file with tasks would nicely compliment this.
