Hello!!! Feel free to mess around with this val and make it your own :). Just click on "Fork" in the top right. You can change the phrases that show up as you click no, you can change the firstImg and secondImg, maybe even add more images. And you can also change the colors and any of the text on the screen! Have fun with it and hopefully your crush says yes hehe.

pipedream
Pipedream helpers Pipedream offers an Accounts API to handle OAuth for you, automatically, and for free. How to do it is covered in this guide . The helper functions below can make it easier to work with various Google API. For example, I used them like so to get all my free/busy times for this week from all my google calendars: import { pipeDreamGoogle } from "https://esm.town/v/stevekrouse/pipedream";
const accountId = "REPLACE_WITH_YOUR_GCAL_ACCOUNT_ID_FROM_PIPEDREAM";
const calendar = await pipeDreamGoogle("calendar", accountId);
// Function to get free/busy information
async function getFreeBusyTimes(calendarId: string) {
const now = new Date();
const startOfWeek = new Date(now);
startOfWeek.setDate(now.getDate() - now.getDay());
const endOfWeek = new Date(startOfWeek);
endOfWeek.setDate(startOfWeek.getDate() + 6);
const requestBody = {
timeMin: startOfWeek.toISOString(),
timeMax: endOfWeek.toISOString(),
items: [{ id: calendarId }],
};
const freeBusyResponse = await calendar.freebusy.query({
requestBody,
});
return freeBusyResponse.data.calendars[calendarId].busy;
}
const calendars = (await calendar.calendarList.list()).data.items;
const freeBusy = await Promise.all(calendars.map(calendar => getFreeBusyTimes(calendar.id)));
console.log(freeBusy); In order for this to work you need to follow the instructions in this guide to save your pipedream API key into your Val Town Environment Variables under pipedream , then connect the google account you care about to Pipedream, and copy it's Pipedream "account id" into your val code. Let me know if you need any help by commenting on this val!

codeOnValTown
Code on Val Town Adds a "Code on Val Town" ribbon to your page. This lets your website visitors navigate to the code behind it. This uses github-fork-ribbon-css under the hood. Usage Here are 2 different ways to add the "Code on Val Town" ribbon: 1. Wrap your fetch handler (recommended) import { modifyFetchHandler } from "https://esm.town/v/andreterron/codeOnValTown?v=50";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";
export default modifyFetchHandler(async (req: Request): Promise<Response> => {
return html(`<h2>Hello world!</h2>`);
}); Example: @andreterron/openable_handler 2. Wrap your HTML string import { modifyHtmlString } from "https://esm.town/v/andreterron/codeOnValTown?v=50";
import { html } from "https://esm.town/v/stevekrouse/html?v=5";
export default async (req: Request): Promise<Response> => {
return html(modifyHtmlString(`<h2>Hello world!</h2>`));
}; Example: @andreterron/openable_html Other ways We made sure this was very modular, so you can also add the ribbon using these methods: Get the element string directly: @andreterron/codeOnVT_ribbonElement Modify an HTTP Response: @andreterron/codeOnVT_modifyResponse Use .pipeThrough to append to a stream: @andreterron/InjectCodeOnValTownStream Customization Linking to the val These functions infer the val using the call stack or the request URL. If the inference isn't working, or if you want to ensure it links to a specific val, pass the val argument: modifyFetchHandler(handler, {val: { handle: "andre", name: "foo" }}) modifyHtmlString("<html>...", {val: { handle: "andre", name: "foo" }}) Styling You can set the style parameter to a css string to customize the ribbon. Check out github-fork-ribbon-css to learn more about how to style the element. modifyFetchHandler(handler, {style: ".github-fork-ribbon:before { background-color: #333; }"}) modifyHtmlString("<html>...", {style: ".github-fork-ribbon:before { background-color: #333; }"}) Here's how you can hide the ribbon on small screens: modifyFetchHandler(handler, {style: `@media (max-width: 768px) {
.github-fork-ribbon {
display: none !important;
}
}`}) To-dos [ ] Let users customize the ribbon. Some ideas are the text, color or placement.

cors_example
CORS issues are the bane of frontend engineers. In Val Town, if you don't customize any CORS headers, we add these defaults: Access-Control-Allow-Origin: "*"
Access-Control-Allow-Methods: "GET,HEAD,PUT,PATCH,POST,DELETE" You can override them if you wish to disallow CORS. This val is a client-side-rendered React app that makes requests to @stevekrouse/cors_example_backend. The backend is in a different val because CORS applies to requests on different domains. The backend has examples of the default permissive CORS behavior and disabled CORS.
