50## How it works
51
52Telegram has a lovely API.
53
541. I created a @ValTownBot via [Bot Father](https://t.me/botfather).
552. I created a [webhook](https://www.val.town/v/stevekrouse.telegramValTownBotWebhook) and [registered it with telegram](https://www.val.town/v/stevekrouse.telegramValTownBotWebhookSetup)
563. Whenever someone new messages @ValTownBot, I generate a secret and save it along with their Chat Id in @stevekrouse/telegramValTownBotSecrets (a private val), and message it back to them
574. Now whenever you call this val, it calls [`telegramValTownAPI`](https://www.val.town/v/stevekrouse.telegramValTownAPI), which looks up your Chat Id via your secret and sends you a message

1# Poll Twitter & Populate SQlite database
2
3The twitter API (or in this case someone else's wrapper over the twitter API) is finicky, so we just try to get one handle per minute, and shove whatever we get into our database, which could be an error message (this is why handles don't have a unique index).

1# [The Big Story](https://tmcw-big_story_visualization.express.val.run/)
2
3This val, along with [@tmcw.big_story](https://www.val.town/v/tmcw.big_story), which requests from the [New York Times API](https://developer.nytimes.com/), and [@tmcw.big_stories_ranks](https://www.val.town/v/tmcw.big_stories_ranks), which contains the data, generates a visualization of top stories on the NYTimes homepage.
4
5This is here just to ask the question – what happens to cover stories over time? Do they slowly drop down the page, or just get replaced by a fully new lede? So far it doesn't have quite enough data to answer that question.

7This val, along with a val called `poll_results` and a val called `poll_options`, lets you conduct a little poll using just Val Town! With the [express API](https://docs.val.town/api#9bff1f5f778e4fe3a143df8169101795), this exposes a web interface in which people can click an option and vote. We make sure everyone only votes once by setting a cookie in their browser.

9This uses [htmx](https://htmx.org/) to make the voting experience slick, [Tailwind](https://tailwindcss.com/) to style the UI, and [htm](https://github.com/developit/htm) to generate HTML for the pages.
