rx-from-csv

RxJS 5 operator to load CSV file

Work in both JavaScript and TypeScript

Installation

npm install rx-from-csv

Use

This library exposes a static fromCSV operator:

fromCSV(path: string, options?: object): Observable<T>;

The new fromCSV operator will load the CSV file from the give path and emit each row as an object, whose keys are column names and values are column values.

Parameters:

• path: csv file path
• options: optional configuration for the csv creation
  • delimiter: a character to separate values. Default: ,
  • noHeaderRow: a boolean value to indicate whether there is a head row.
  • columns: an array of column names. This is required if noHeaderRow is true.

Example

import { fromCSV } from 'rx-from-csv';
 
/**
 * For example, there is a data.csv with content
 *
 * id,name
 * 1,"Mike",
 * 2,"Tommy"
 */
 
fromCSV('data.csv')
  .subscribe((data) => {
    console.log(data);
  });
 
/**
 * It will output:
 * { id: '1', name: 'Mike' }
 * { id: '1', name: 'Tommy' }
 */
