parallel-promise-queue v2.0.1

Parallel Promise Queue

Promise Queue utility to execute a single promise against an array of values with concurrency and ordering control. The idea originates from a highly recommended book (Node.js Design Patterns), which inspired me to create a module written in TypeScript.

Installing

npm install parallel-promise-queue

or

yarn add parallel-promise-queue

Running the tests

npm test

or

yarn test

Using

promises

The module is a function which takes four parameters. | Param | Type | Required | Default | Description | | -- | -- | -- | -- | -- | | items | Array | yes | n/a | An array of values of any kind to be be passed to the Promise | | promise | Promise | yes | n/a | A Promise or function which returns a promise | | concurrency | Integer | no | 1 | Number of concurrent executions between 1 and 5 | | sequential | Boolean | no | true | Whether or not ordering should be maintained in returned results array |

Example

const promises = require('parallel-promise-queue');
promises(promiseMethod, dataArray, 1, true)
	.then(result => resultHandler)
    .catch(error => errorHandler);
