stact-hooks

Manage a registry of function stacks and run them.

stact-hooks

Manage a registry of function stacks and run them.

stact-hooks is a simple wrapper around stact.

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

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

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 (errresults) {
 
});
 
// Or run it in series mode. 
hooks('validate').runSeries(function (errresults) {
 
});
