subidentity-package

Motivation

This package provides functionality to fetch identities and search identities by address or any identity field from any Substrate chain implementing the identities pallet. It was developed for use in SubIdentity, a Substrate identity directory, and contains all therefore required methods and interfaces.

npm run build

Tests

Unit

npm run test

Lint

npm run lint

Installation

npm install @npmjs_tdsoftware/subidentity

Available features

import { implementsIdentityPallet } from "@npmjs_tdsoftware/subidentity"

let wsProvider = "your-ws-provider"
let isImplementingIdentityPallet = await implementsIdentityPallet(wsProvider);

isArchiveNode

Returns true, if the chain of provided wsProvider is running on archive mode.

import { isArchiveNode } from "@npmjs_tdsoftware/subidentity"

let wsProvider = "your-ws-provider"
let isMyNodeArchive = await isArchiveNode(wsProvider);

getChainName

import { getChainName } from "@npmjs_tdsoftware/subidentity"

let wsProvider = "your-ws-provider"
let chainName = await getChainName(wsProvider);

getTokenDetails

Returns the token symbol and decimals of the chain of provided wsProvider.

import { Token, getTokenDetails } from "@npmjs_tdsoftware/subidentity"

let wsProvider = "your-ws-provider"
let tokenDetails = await getTokenDetails(wsProvider);

getChainStatus

Returns the chain status of the chain of provided wsProvider.

import { ChainStatus, getChainStatus } from "@npmjs_tdsoftware/subidentity"

let wsProvider = "your-ws-provider"
let chainStatus: ChainStatus = await getChainStatus(wsProvider);

connectToWsProvider

Returns ApiPromise instance using the supplied wsProvider.
