Utilities

Standalone utilities are no longer exported from a separate package subpath. Current utilities are exposed through the client or the documented package subpaths below.

OBS

OBS helpers are available from the authenticated client's BaseClient:

const metadata = await client.base.obs.getMessageObsMetadata({
  messageId: "MESSAGE_ID",
});

const file = await client.base.obs.downloadMessageData({
  messageId: "MESSAGE_ID",
});

Media upload helpers are available on the same object:

const message = await client.base.obs.uploadMediaByE2EE({
  to: "u...",
  oType: "image",
  data: imageFile,
  filename: "image.png",
});

Implementation details live in packages/linejs/base/obs/mod.ts.

Storage

Storage helpers are exported from @evex/linejs/storage:

import { FileStorage, MemoryStorage } from "@evex/linejs/storage";

const storage = new FileStorage("./storage.json");

Use FileStorage when login state, E2EE keys, and request sequence state must survive process restarts. Use MemoryStorage only for short-lived clients.

Base Helpers

Low-level helpers that are part of the public base package are exported from @evex/linejs/base:

import { BaseClient, continueRequest, InternalError } from "@evex/linejs/base";

The package exports are defined in packages/linejs/deno.json.
