Usage

Command line utility

If you install this package globally you can use command yle-teletext to retrieve pages and display them in your console.

$ yle-teletext [page = 100] [subpage = 1]

Library

The library exports a single function called get, which retrieves an teletext page, it's subpages (optionally) and so on. It's TypeScript type declaration looks like this:

get(
  page: number = 100,
  subpage: number = 1,
  fetchSubPages: boolean = true,
) => Promise<string[]>;

It returns an array of subpages which each containing text only version of the page contents. If the page does not exist, or some other network related error occurs, the promise will fail.

And this is how you can use it:

import { get } from 'yle-teletext-scraper';

get(100, 1)
  .then((pages) => {
    pages.forEach((page) => {
      console.log(page);
    });
  })
  .catch((error) => {
    console.error(error);
  });
