Simple task runner

Installation

npm install runner

Usage

Runner can be started by using npm or npx commands.

Run with npm:

npm run build

where build is an npm script in the package.json which contains a runner command.

Run with npx:

npx runner

The runner command format:

runner [options] [<task>]

Available options:

Option | Description --------------|------------- -c, --config | Configuration file is a script which contains tasks definitions. Default value - runner.js. -s, --serial | Run all given tasks sequentially (instead of in parallel).

These two commands are identical:

npx runner
npx runner --config runner.js

To run a webpack:build task from a custom configuration file:

npx runner -c tasks/develop.js webpack:build 

Without the task name starts the default task:

npx runner -c tasks/develop.js 

API

Add to the scope:

import runner from 'runner';

Create a simple task:

runner.task('make', function () {
    // some actions
});

More examples of tasks creation and execution are available in the cjs-runner package.

Add an alias to an existing task:

runner.alias('build', 'make');

Run task on a key or keys combination press:

runner.keystroke('build', 'ctrl+b');

Files watching

To execute a specific task on some file changes:

runner.watch('src/script/**/*.js', 'webpack:build');

To execute a named or anonymous function:

runner.watch('src/script/**/*.js', function rebuild ( done ) {
    // function name "rebuild" is used as task name
    // otherwise <noname> is printed
    done();
});

To execute task series:

runner.watch('src/script/**/*.js', runner.serial('lint', 'build'));

Before calling runner.watch it's possible to configure the watch:

runner.watch.config = {
    // some configuration 
};

All available configurations you can see in the underlying chokidar package.
