Exponential Sum Plot Generator An homage to John D. Cook's Exponential Sum of the Day The plot shows the partial sums of the exponential sum: Σ(n=0 to N) exp(2πi(n/m + n²/d + n³/y)) The real part of the sum is plotted on the x-axis, and the imaginary part of the sum is plotted on the y-axis.

Example Hono app with a Fiberplane API explorer. For an example with OpenApiHono , see: https://www.val.town/x/fiberplane/fiberplaneHonoZodStarter Import @fiberplane/hono import { createFiberplane, createOpenAPISpec } from "https://esm.sh/@fiberplane/hono@0.4.4"; Generate a simplified API spec (if you don't already have one) app.get("/openapi.json", async (c) => { const spec = createOpenAPISpec(app, { info: { title: "My Hono API", version: "1.0.0" }, }); return c.json(spec); }); Mount the api explorer This will mount it at the root /* , but you can mount it to another route, like /fp/* if you are using / for your main app. We recommend / if your Hono app is an API without a frontend. app.use( "/*", createFiberplane({ openapi: { url: "/openapi.json" }, }), ); Visit your Val's root route to play with the API explorer! How it Works createFiberplane mounts Fiberplane on your app at the specified path, which can be used to explore the api's routes and make requests. Think of it like an embedded, lightweigh postman. If you don't have an API spec at the ready, then the createOpenAPISpec utility helps create a simple OpenAPI spec from all routes in the application. ( Note that this simple spec does not include information on expected query parameters, headers, or payloads! )

Push Notification Sender This val can be used in other vals to send notifications to a segment using OneSignal's REST API This is really handy if you want to send push notifications to your phone without building a native app! I built a barebones React PWA that asks for a password then loads the OneSignal Web SDK that I deployed to Netlify for free. OneSignal has easy to follow docs so you can build this functionality into a React, Angular, Vue app or even Wordpress! Then install the PWA on your platform of choice and you're off to the races! Setup Save your ONESIGNAL_TOKEN and SEGMENT_APPID from OneSignal to your Val Town environment variables Import into another val! import sendNotification from "https://esm.town/v/gwoods22/sendNotification";

easyAQI Get the Air Quality Index (AQI) for a location via open data sources. It's "easy" because it strings together multiple lower-level APIs to give you a simple interface for AQI. Accepts a location in basically any string format (ie "downtown manhattan") Uses Nominatim to turn that into longitude and latitude Finds the closest sensor to you on OpenAQ Pulls the readings from OpenAQ Calculates the AQI via EPA's NowCAST algorithm Uses EPA's ranking to classify the severity of the score (ie "Unhealthy for Sensitive Groups") It uses blob storage to cache the openai location id for your location string to skip a couple steps for the next time. Example usage @stevekrouse.easyAQI({ location: "brooklyn navy yard" }) // Returns { "aqi": 23.6, "severity": "Good" } Forkable example: val.town/v/stevekrouse.easyAQIExample Also useful for getting alerts when the AQI is unhealthy near you: https://www.val.town/v/stevekrouse.aqi

Manage your blobs using VS Code ! Just fork this val to install it, and authenticate with your account email.

Val Town Company *@val.town Email Routing This val forwards emails to addresses that don't exist to all of us at Val Town. For example, this forwards feedback@val.town to all of us. We achieve this by forwarding emails to this email handler, and this email handler forwards them along. To accomplish this without Val Town would require setting up a Google Group. I prefer doing it in code. Over time we will have more complex routing here.
