Using Components

All Asteria Hyperion components have to be imported with the ES6 syntax:

import { Hyperion } from 'asteria-yperion';
import * as path from 'path';

const dataPath: string = path.join(__dirname, 'data');
const inputPath: string = path.join(dataPath, 'worldcitiespop.csv');
const outputPath: string = path.join(dataPath, 'us-mega-cities.csv');

Hyperion.build({
    name: 'UsMegaCities',
    processes: [
        {
            type: 'read-file',
            config: inputPath
        },
        {
            type: 'csv-to-list',
            config: {
                separator: ';',
                colsMap: [
                    { id: 0, prop: 'country' },
                    { id: 2, prop: 'city' },
                    { id: 3, prop: 'region' },
                    { id: 4, prop: 'population' },
                    { id: 5, prop: 'latitude' },
                    { id: 6, prop: 'longitude' }
                ]
            }
        },
        {
            type: 'filter',
            config: 'population > 1000000 AND country = \'us\''
        },
        {
            type: 'list-to-csv',
            config: { separator: ';' }
        },
        {
            type: 'write-file',
            config: outputPath
        }
    ]
