base-task - npm

Base plugin that provides a very thin wrapper around https://github.com/doowb/composer for adding task methods to your Base application.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your ❤️ and support.

Install with npm:

$ npm install --save base-task

const Base = require('base');
const tasks = require('base-task');
const base = new Base();
 
base.use(tasks());
 
 
base.task('foo', cb => {
  console.log('this is foo!');
  cb();
});
 
base.task('bar', cb => {
  console.log('this is bar!');
  cb();
});
 
 
base.build(['foo', 'bar'])
  .then(() => {
    
    
    console.log('done!');
  })
  .catch(console.error)

See the composer documentation for more details, or to create bug reports related to running or registering tasks.

Register a task

Params

• name {String}: Task name to register (tasks are cached on app.tasks)
• dependencies {String|Array|Function}: String, list or array of tasks.
• callback {Function}: Function to be called when the task is executed. Task functions should either return a stream or call the callback to let composer know when the task is finished.

Examples

Register a task.

app.task('default', function() {
  
  return app.src('pages/*.hbs')
    .pipe(app.dest('dist'));
});

Register a task with dependencies (other tasks to run before executing the task):

app.task('site', ['styles'], function() {
  return app.src('pages/*.hbs')
    .pipe(app.dest('dist'));
});
 
app.task('default', ['site']);

Get a task

const task = app.task('site');

Run a task or array of tasks.

Promise examples

app.build();
app.build('default');
 
app.build(['foo', 'bar'])
  .then(() => console.log('done!'))
  .catch(console.error);

Callback examples

app.build(function(err, results) {
  if (err) return console.error(err);
  console.log(results);
});
 
app.build('default', function(err, results) {
  if (err) return console.error(err);
  console.log(results);
});
 
app.build(['foo', 'bar'], function(err, results) {
  if (err) return console.error(err);
  console.log(results);
});

Compose task or list of tasks into a single function that runs the tasks in series.

Params

• tasks {String|Array|Function}: List of tasks by name, function, or array of names/functions.
• returns {Function}: Composed function that may take a callback function.

Example

app.task('foo', cb => {
  console.log('this is foo');
  cb();
});
 
const build = app.series('foo', cb => {
  console.log('this is bar');
  cb();
});
 
build(function(err) {
  if (err) return console.error(err);
  console.log('finished');
});

Compose task or list of tasks into a single function that runs the tasks in parallel.

Params

• tasks {String|Array|Function}: List of tasks by name, function, or array of names/functions.
• returns {Function}: Composed function that may take a callback function.

Example

app.task('foo', cb => {
  setTimeout(function() {
    console.log('this is foo');
    cb();
  }, 500);
});
 
const build = app.parallel('foo', cb => {
  console.log('this is bar');
  cb();
});
 
build(function(err) {
  if (err) return console.error(err);
  console.log('finished');
});

The following events are emitted by composer. See the composer docs for more details

Emitted when a task is register, starting and finished.

app.on('task', function(task) {
  console.log(task.status);
  
});

Emitted when a build is starting and finished.

app.on('build', function(build) {
  console.log(build.status);
  
});

• Bumped composer to v2.0.0.

• Bumped composer to v0.11.0, so the .watch method is no longer included by default. To add .watch, use the base-watch plugin.
