Parallel processing module for JavaScript that can specify the number of concurrent executions.

Module

Usage

let result_info = await concurrent_promise.execute(
        promise_function_array, // Array of functions that return Promise (Note: it's not Promise itself)
        max_concurrent_worker // Max concurrent Promise number (default: 10)
    );
//  result_info = {
//      promise_results : <Array of results for each Promise>,
//      success_list : <Array of successful Promise results>,
//      failure_list : <Array of failed Promise results>,
//  }

Trial

Browser

Open the test page in your browser and follow the instructions to run it.

Node.js

Install

$ cd js-concurrent_promise
$ yarn install

Examples

$ node -i
// [load modules]
const { concurrentPromise, concurrent_promise, test } = require( './test/node_test.js' );

// [run]
//   test.run( target_module, promise_number, max_concurrent_worker );

// target_module = concurrentPromise: simple version (run Promise.all with each max_concurrent_worker)
test.run( concurrentPromise, 100, 10 );

// target_module = concurrent_promise: efficiency improvement version
test.run( concurrent_promise, 100, 10 );

// [cancel]
test.cancel();
