stact-hooks

Manage a registry of function stacks and run them.

About

stact-hooks is a simple wrapper around stact.

It provides a registry-like interface to namespaced 'stacks' of functions.

Example

var hooks = require('stact-hooks')();

hooks('before:save').add(function (next) {
  // Do something.
  next();
});

hooks('before:save').add(function (next) {
  // Do something.
  next();
});

hooks('after:save').add(function (next) {
  // Do something.
  next();
});

hooks('before:save').run(function (err, results) {
  if (err) // Handle err.
  save(function (err) {
    if (err) // Handle err.
    hooks('after:save').run(function (err, results) {
      if (err) // Handle err.
    });
  });
}
});

API

stact-hooks exports a single function, which returns a hook 'registry'.

The registry is a function that accepts one argument. You pass this function a string and it returns you a stact function stack. Subsequent calls with the same string will return the same stack.

var createHooks = require('stact-hooks');

var hooks = createHooks();

hooks('validate').add(function (next) {
  // Do something.
});

hooks('validate').add(function (next) {
  // Do something.
});

// The 'validate' namespace is now a stack with two functions on it.

// You could 'run' this stack like so:
hooks('validate').run(function (err, results) {

});

// Or run it in series mode.
hooks('validate').runSeries(function (err, results) {

});
