sails-hook-ohmytasks

Hook for running tasks before lift

In config/ohmytasks.js

{
  toDo: [], //this is a list of tasks to be executed
 
  before: function(sails, next){
  },
  //function to be executed before task execution
 
  onLift: function(){
  },
  //function to execute on lifted event
 
  after: function(sails, next){
  },
  //function to be executed after task execution
 
  dirname: 'folder-with-tasks'
  //defaults to ohmytasks, place this dir under root folder
}

toDo expects a list of JSON's like this

{
  tasks: ['name-of-task']
}

to be executed asynchronously or if tasks need to be executed in order:

{
  tasks: ['task1', 'task2', ...],
  order: true
}

the tasks are executed in the order specified in the list, and pass arguments to next task.

The name of each task refers to a file inside the folder specified in the config, each file should have the following structure:

module.exports = function(sails, arg1, arg2, callback){
 
  //task code
  // return callback(err, sails, other-args);
  // or
  // return callback(err); if order was not specified
}

Example

In config/ohmytasks.js

module.exports.ohmytasks = {
 
  toDo: [
    {
      tasks: ['task1']
    },
    {
      tasks: ['task2', 'task3'],
      order: true
    }
  ],
 
  before: function(sails, cb){
    console.log("----------- Loading config -----------\n");
    return cb();
  },
 
  onLift: function(){
    console.log("----------- Lift -----------\n");
  },
 
  after: function(sails, cb){
    console.log("----------- Done -----------\n");
    return cb();
  },
 
  dirname: 'ohmytasks'
 
}

with tasks definitions:

ohmytasks/task1.js

module.exports = function(sails, next){
  console.log("async task");
  return next();
};

ohmytasks/task2.js

module.exports = function(sails, next){
  console.log("first task");
  return next(null, sails, "foo");
};

ohmytasks/task3.js

module.exports = function(sails, text, next){
  console.log("second task");
  console.log(text)
  return next(new Error("i don't wanna lift"));
};

The output will be something like:

  ----------- Loading config -----------
  first task
  async task
  second task
  foo
 
  // error description
  i don't wanna lift

Since task2.js returns an error, sails won't lift and will throw the error.

Notes

• This hook overrides sails.config.bootstrap so any logic there must be in one task or in before and after function definitions.
• Only tasks inside the dirname folder will be loaded, other folders inside dirname will be ignored.
