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" }),
},
]);
// 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.
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
}
You can add cache directives to each pipe.
tb.buildPipe({
pipe: "some_pipe__v1",
parameters: z.object({
hello: z.string()
}),
data: z.object({
response: z.string()
}),
opts: {
cache: "no-store" // <-------- Add this
};
});
```ts
tb.buildPipe({ pipe: "some_pipe__v1", parameters: z.object({ hello: z.string() }), data: z.object({ response: z.string() }), opts: { next: { revalidate: 900 ;// <-------- Add this } }; });
