Installation

You can use ic-management-js by installing it in your project.

npm i @dfinity/ic-management

The bundle needs peer dependencies, be sure that following resources are available in your project as well.

npm i @dfinity/agent @dfinity/candid @dfinity/principal @dfinity/utils

Usage

The features are available through the class ICMgmtCanister. It has to be instantiated with a canister ID.

e.g. fetching a token metadata.

import { ICManagementCanister } from "@dfinity/ic-management";
import { createAgent } from "@dfinity/utils";

const agent = await createAgent({
  identity,
  host: HOST,
});

const { canisterStatus } = ICManagementCanister.create({
  agent,
});

const { status, memory_size, ...rest } = await canisterStatus(YOUR_CANISTER_ID);

⚙️ uploadChunk

Upload chunks of Wasm modules that are too large to fit in a single message for installation purposes.

Method	Type
uploadChunk	({ canisterId, ...rest }: UploadChunkParams) => Promise<chunk_hash>

Parameters:

• params.canisterId: The canister in which the chunks will be stored.
• params.chunk: A chunk of Wasm module.

🔗 Source

⚙️ clearChunkStore

Clear the entire chunk storage of a canister.

Method	Type
clearChunkStore	({ canisterId, }: ClearChunkStoreParams) => Promise<void>

Parameters:

• params.canisterId: The canister in which the chunks are stored.

🔗 Source

⚙️ storedChunks

List the hashes of chunks in the chunk storage of a canister.

Method	Type
storedChunks	({ canisterId, }: StoredChunksParams) => Promise<chunk_hash[]>

Parameters:

• params.canisterId: The canister in which the chunks are stored.

🔗 Source

⚙️ installChunkedCode

Installs code that had previously been uploaded in chunks.

Method	Type
installChunkedCode	({ mode, arg, senderCanisterVersion, chunkHashesList, targetCanisterId, storeCanisterId, wasmModuleHash, }: InstallChunkedCodeParams) => Promise<void>

Parameters:

• params.mode: Installation, re-installation or upgrade.
• params.arg: The arguments of the canister.
• params.senderCanisterVersion: The optional sender_canister_version parameter can contain the caller's canister version.
• params.chunkHashesList: The list of chunks of the Wasm module to install.
• params.targetCanisterId: Specifies the canister where the code should be installed.
• params.storeCanisterId: Specifies the canister in whose chunk storage the chunks are stored (this parameter defaults to target_canister if not specified).
• params.wasmModuleHash: The Wasm module hash as hex string. Used to check that the SHA-256 hash of wasm_module is equal to the wasm_module_hash parameter and can calls install_code with parameters.

⚙️ bitcoinGetUtxos

Given a get_utxos_request, which must specify a Bitcoin address and a Bitcoin network (mainnet or testnet), the function returns all unspent transaction outputs (UTXOs) associated with the provided address in the specified Bitcoin network based on the current view of the Bitcoin blockchain available to the Bitcoin component.

Method	Type
bitcoinGetUtxos	(params: BitcoinGetUtxosParams) => Promise<bitcoin_get_utxos_result>

Parameters:

• params.network: Tesnet or mainnet.
• params.filter: The optional filter parameter can be used to restrict the set of returned UTXOs, either providing a minimum number of confirmations or a page reference when pagination is used for addresses with many UTXOs.
• params.address: A Bitcoin address.
