Function createCandidAdapter

  • The CandidAdapter class is used to interact with a canister and retrieve its Candid interface definition. It provides methods to fetch the Candid definition either from the canister's metadata or by using a temporary hack method. If both methods fail, it throws an error.

    Example


    import { agentManager } from "./agent"

    const candidAdapter = createCandidAdapter({ agentManager })

    const canisterId = "ryjl3-tyaaa-aaaaa-aaaba-cai"

    // Usage example
    try {
    const definition = await candidAdapter.getCandidDefinition(canisterId)
    console.log(definition)
    } catch (error) {
    console.error(error)
    }

    Using createReactorCore with CandidAdapter

    You can use the candidAdapter to fetch the Candid definition and then pass it to the createReactorCore function.

    import { createReactorCore, createCandidAdapter } from "@ic-reactor/core"
    import { agentManager } from "./agent"

    const candidAdapter = createCandidAdapter({ agentManager })

    const canisterId = "ryjl3-tyaaa-aaaaa-aaaba-cai" // NNS ICP Ledger Canister

    // Usage example
    try {
    const { idlFactory } = await candidAdapter.getCandidDefinition(canisterId)
    const { callMethod } = createReactorCore({
    agentManager,
    canisterId,
    idlFactory,
    })

    const name = await callMethod("name")
    console.log(name) // { name: 'Internet Computer' }
    } catch (error) {
    console.error(error)
    }
