Bootstrapper

A bootstrapper library

Example ES6:

import Bootstrapper from 'function-bootstrapper';
import Promise from 'bluebird';

const bootstrap = new Bootstrapper({
    ignoreError: true,
    chain: [
        {
            promise: true,
            payload: {
                "importantData": "Hello"  
            },
            function: function(payload) {
                return new Promise((resolve, reject) => {
                    doSomething(payload, (error) => {
                        if (error){
                            reject(error);
                        } else {
                            resolve();
                        }
                    });
                });
            }
        },
        {
            payload: '{"json":true}',
            function: function(payload){
                return JSON.parse(payload);
            }
        }
    ]
});

bootstrap.on('progress',console.log);
bootstrap.promise.then(() => {
    console.log("Finished bootstrap");
}).catch(console.error);

Example normal:

const Bootstrapper = require('function-bootstrapper');
const Promise = require('bluebird');

const bootstrap = new Bootstrapper({
    ignoreError: true,
    chain: [
        {
            promise: true,
            payload: {
                "importantData": "Hello"  
            },
            function: function(payload) {
                return new Promise(function (resolve, reject) {
                    doSomething(payload, (error) => {
                        if (error){
                            reject(error);
                        } else {
                            resolve();
                        }
                    });
                });
            }
        },
        {
            payload: '{"json":true}',
            function: function(payload){
                return JSON.parse(payload);
            }
        }
    ]
});

bootstrap.on('progress',console.log);
bootstrap.promise.then(function () {
    console.log("Finished bootstrap");
}).catch(console.error);

BootstrapperConfig : Object

BootChainFragment : Object

Kind: global typedef
Properties

Name	Type	Description
promise	Boolean	If false, it needs to be sync
function	function
payload	*	The payload is the first arguement for the function
ignoreError	Boolean	Don't reject if a error occurs, but only for this fragment
pipeTo	function	This function will be executed after the main function finished. The first argument is the result of the function.

Kind: global typedef
Properties

Name	Type	Description
ignoreError	Boolean	Don't reject if a error occurs
parallel	Boolean	Run Bootchain parallel, how much operation parallel is defined with limit. You only need to define one property, parallel or limit. If not limit is set and parallel is true, cpu core count will be used.
limit	int	How much operation parallel. You only need to define one property, parallel or limit. If not limit is set and parallel is true, cpu core count will be used.
