@chronark/zod-bird v0.3.9

• typesafe
• handles building the url params for you
• easy transformation of resulting data
• built in cache directives for nextjs
• built in retry logic for ratelimited requests

import { Tinybird } from "@chronark/zod-bird";
import { z } from "zod";

const tb = new Tinybird({ token: "token" });

export const getEvents = tb.buildPipe({
  pipe: "get_events__v1",
  parameters: z.object({
    tenantId: z.string(),
  }),
  data: z.object({
    event: z.string(),
    time: z.number().transform((t) => new Date(t)),
  }),
});


const res = await getEvents({ tenantId: "chronark" })

// res.data = {event: string, time: Date}[]
// if no rows found, res.data will be an empty array

Install

npm i @chronark/zod-bird

Ingesting Data

// lib/tinybird.ts
import { Tinybird } from "./client";
import { z } from "zod";

const tb = new Tinybird({ token: process.env.TINYBIRD_TOKEN! });

export const publishEvent = tb.buildIngestEndpoint({
  datasource: "events__v1",
  event: z.object({
    id: z.string(),
    tenantId: z.string(),
    channelId: z.string(),
    time: z.number().int(),
    event: z.string(),
    content: z.string().optional().default(""),
    metadata: z.string().optional().default(""),
  }),
});

// somewhere.ts
import { publishEvent } from "./lib/tinybird";

await publishEvent({
  id: "1",
  tenantId: "1",
  channelId: "1",
  time: Date.now(),
  event: "test",
  content: "test",
  metadata: JSON.stringify({ test: "test" }),
});

Or multiple events in bulk, using a single request to Tinybird.

// somewhere.ts
import { publishEvent } from "./lib/tinybird";

await publishEvent([
  {
    id: "1",
    tenantId: "1",
    channelId: "1",
    time: Date.now(),
    event: "test",
    content: "test",
    metadata: JSON.stringify({ test: "test" }),
  },
  {
    id: "2",
    tenantId: "2",
    channelId: "2",
    time: Date.now(),
    event: "test2",
    content: "test2",
    metadata: JSON.stringify({ test2: "test2" }),
  },
]);

Querying Endpoints

// lib/tinybird.ts
import { Tinybird } from "./client";
import { z } from "zod";

const tb = new Tinybird({ token: process.env.TINYBIRD_TOKEN! });

export const getChannelActivity = tb.buildPipe({
  pipe: "get_channel_activity__v1",
  parameters: z.object({
    tenantId: z.string(),
    channelId: z.string().optional(),
    start: z.number(),
    end: z.number().optional(),
    granularity: z.enum(["1m", "1h", "1d", "1w", "1M"]),
  }),
  data: z.object({
    time: z.string().transform((t) => new Date(t).getTime()),
    count: z
      .number()
      .nullable()
      .optional()
      .transform((v) => (typeof v === "number" ? v : 0)),
  }),
});

// somewhere.ts
import { getChannelActivity } from "./lib/tinybird";


const res = await getChannelActivity({
   tenantId: "1",
   channelId: "1",
   start: 123,
   end: 1234,
   granularity: "1h"
})

res is the response from the tinybird endpoint, but now fully typed and the data has been parsed according to the schema defined in data.

Error handling

For 429 (rate limit exceeded) and 500 errors, zod-bird automatically retries them (source code).

All other errors will throw an Exception, so you should catch it via a try catch:

try {
    const res = await getEvents({ tenantId: "chronark" })
    return res.data
} catch (e) {
    console.error(e)
    return e.messsage
}

Advanced

Caching

You can add cache directives to each pipe.

Disable caching (useful in Next.js where everything is cached by default)

tb.buildPipe({
  pipe: "some_pipe__v1",
  parameters: z.object({
   hello: z.string()
  }),
  data: z.object({
    response: z.string()
  }),
   opts: {
      cache: "no-store" // <-------- Add this
   };
});

Cache for 15 minutes

tb.buildPipe({
  pipe: "some_pipe__v1",
  parameters: z.object({
   hello: z.string()
  }),
  data: z.object({
    response: z.string()
  }),
   opts: {
      next: {
        revalidate: 900 ;// <-------- Add this
      }
    };
});
