API v1

/**
 * @return a csv string parser as specified by the given `config` options object
 */
export declare function getCsvParser<T = string[]>(
  config?: Partial<CSV_PARSER_SPEC>
): (input: string) => T[]

export interface CSV_PARSER_SPEC {
  /**
   * when true, the first line is interpreted as a header (list of field names),
   * in which case the parsed entries are objects
   * instead of a list of field values.
   * default: false
   */
  header: boolean
  /**
   * field delimiter character,
   * default: `,`
   */
  delimiter: string
  /**
   * escape character,
   * default: `"`
   */
  escape: string
  /**
   * called for each parsed field,
   * with its index in the parsed record.
   * defaults to a function that unescapes the field string
   */
  postprocess: (field: string, index?: number) => string
}

TypeScript

although this library is written in TypeScript, it may also be imported into plain JavaScript code: code editors will still benefit from the available type definition, e.g. for helpful code completion.
