trip

The minimalist's task runner.

Install

> yarn global add trip

# or...
> npm install trip -g

Or install it locally inside a project if you prefer.

Usage

1. Make a tripfile.js and export some functions from it.
2. Run the named functions from your CLI using trip FUNCTION_NAME.

You can use ES2016 syntax and it will just work.

You can run multiple tasks in series like this: > trip task1 task2 task3

Example tripfile.js

A tripfile is a module that exports some functions:

// > trip speak
export function speak() {
    console.log('Hello world!');
}

// > trip wow
export async function wow() {
    await somePromise();
}

// > trip
export async default function () {
    console.log('this is the default task');
}

Flags

You can pass boolean flags from the command line, using : as a delimiter.

For example, the command > trip foo:bar:baz will call the foo function with the flags { bar: true, baz: true }.

// run this with `trip speak:leaving:polite` to set enable the flag
export function speak({ leaving }) {
    console.log((leaving ? 'Goodbye' : 'Hello') + ' world!');
}

ES2016

Your tripfile is automatically compiled with Babel. Trip uses the env and preset and most stage-0 features by default, so you don't need to bring your own Babel config. But if you do have your own config in a .babelrc or package.json, Babel will use that instead.

Async tasks

Trip understands several kinds of async:

• async functions
• functions that return promises
• functions that return streams
• functions that explicitly accept a done callback as a second argument (for compatibility with old APIs)

When you run multiple tasks from one command (> trip task1 task2), trip waits for each task to finish before starting the next.
