Creating plugins

A plugin can take any arguments and must return a function.

sync

Plugins just return a value.

Example:

var plugins = new Plugins();

plugins
  .use(function (str) {
    return str + 'a';
  })
  .use(function (str) {
    return str + 'b';
  })
  .use(function (str) {
    return str + 'c';
  });

console.log(plugins.run('alphabet-'));
//=> 'alphabet-abc'

async

Pass next as the last argument to run plugins asynchronously.

Example:

var plugins = new Plugins();

plugins
  .use(function (str, next) {
    next(null, str + 'a');
  })
  .use(function (str, next) {
    next(null, str + 'b');
  })
  .use(function (str, next) {
    next(null, str + 'c');
  });

plugins.run('alphabet-', function (err, str) {
  console.log(str); //=> 'alphabet-abc'
});

Directly run plugins

To run plugins without .use(), pass an array of functions as a section argument to .run().

sync example:

var plugins = new Plugins();

var a = function(val) {
  return val + 'a';
};
var b = function(val) {
  return val + 'b';
};
var c = function(val) {
  return val + 'c';
};

console.log(plugins.run('alphabet-', [a, b, c]));
//=> 'alphabet-abc'

async example:

var plugins = new Plugins();

var a = function (str, next) {
  next(null, str + 'a');
};
var b = function (str, next) {
  next(null, str + 'b');
};
var c = function (str, next) {
  next(null, str + 'c');
};

plugins.run('alphabet-', [a, b, c], function (err, str) {
  console.log(str); //=> 'alphabet-abc'
});
