Tigris

A Fly.Bucket is Tigris S3-compatible object storage, billed through Fly. It is org-scoped. There is no parent App.

Tigris speaks the S3 API. Bind PutObject / GetObject in a Service. Alchemy injects the Tigris endpoint and credentials. You never read AWS_* yourself.

Create a Bucket

Alchemy generates a unique name unless you pass one.

const data = yield* Fly.Bucket("Data");

A stable name

Pass name when you need a stable Tigris bucket name.

const data = yield* Fly.Bucket("Data", {
  name: "my-bucket",
});

Put and get objects

Bind PutObject / GetObject in Service init. Provide the matching *Http layers.

import * as HttpServerResponse from "effect/unstable/http/HttpServerResponse";

export default class Api extends Fly.Service<Api>()(
  "Api",
  { app: Site, main: import.meta.url, port: 3000 },
  Effect.gen(function* () {
    const putObject = yield* Fly.PutObject(Data);
    const getObject = yield* Fly.GetObject(Data);

    return {
      fetch: Effect.gen(function* () {
        yield* putObject({
          Key: "hello.txt",
          Body: "hello",
          ContentType: "text/plain",
        });
        const obj = yield* getObject({ Key: "hello.txt" });
        return HttpServerResponse.json({ ok: obj.ETag !== undefined });
      }),
    };
  }).pipe(Effect.provide([Fly.PutObjectHttp, Fly.GetObjectHttp])),
) {}

Public access

Buckets are private by default. public: true serves objects without credentials.

const assets = yield* Fly.Bucket("Assets", {
  public: true,
});

Custom domain

domainName sets website.domain_name on the add-on. Point a CNAME at {name}.t3.tigrisbucket.io.

const assets = yield* Fly.Bucket("Assets", {
  public: true,
  domainName: "assets.example.com",
});

Organization

Org defaults to the current token. Pass orgSlug to pin it.

const data = yield* Fly.Bucket("Data", {
  orgSlug: "my-org",
});

Where next

Services is the Machine that binds PutObject / GetObject. The Bucket reference lists every prop.
