# Producing messages

Build the canonical envelope with `EnvelopeCodec.make`, encode it to JSON with
`EnvelopeCodec.encode`, then publish the bytes with your own broker client.

```ts
import { EnvelopeCodec } from "@babelqueue/core";

const env = EnvelopeCodec.make(
  "urn:babel:orders:created",
  { order_id: 1042, amount: 99.90 },
  { queue: "orders" },
);

const body = EnvelopeCodec.encode(env); // compact UTF-8 JSON string
// await redis.rpush("queues:orders", body);
//   /  channel.sendToQueue("orders", Buffer.from(body));
```

CommonJS works too: `const { EnvelopeCodec } = require("@babelqueue/core")`.

`encode` produces the canonical `schema_version: 1` envelope, with `meta.lang`
set to `"node"`:

```json
{
  "job": "urn:babel:orders:created",
  "trace_id": "7b3f9c2a-e41d-4f88-9b2a-1c0d5e6f7a8b",
  "data": { "order_id": 1042, "amount": 99.90 },
  "meta": { "id": "f1e2d3c4-b5a6-4789-90ab-cdef01234567", "queue": "orders", "lang": "node", "schema_version": 1, "created_at": 1749132727000 },
  "attempts": 0
}
```
