Fetch Follows

This section covers how to fetch follows on the Subsocial blockchain.

Check if a user is following a space or account

isSpaceFollower

This checks if an account is following a particular space.

substrateApi.isSpaceFollower(myAddress: AnyAccountId, spaceId: AnySpaceId): Promise<boolean>

Example:

const isFollower = await substrateApi.isSpaceFollower('3osmnRNnrcScHsgkTJH1xyBF5kGjpbWHsGrqM31BJpy4vwn8', idToBn('1'))

isAccountFollower

This checks if an account is following a particular account.

SubstrateApi.isAccountFollower(myAddress: AnyAccountId, followedAddress: AnyAccountId): Promise<boolean>

const isFollower = await substrateApi.isAccountFollower('3osmnRNnrcScHsgkTJH1xyBF5kGjpbWHsGrqM31BJpy4vwn8', idToBn('1'))

🆃 AnyAccountId: AccountId | string

🅸 AnySpaceId: SpaceId | BN

Find and load a list of space followers

spacesFollowedByAccount

Get an array of space IDs that an account is following.

readyApi.query.spaceFollows.spacesFollowedByAccount(account: AccountId)

Example:

import { Vec } from "@polkadot/types";

import { SpaceId as SubstrateSpaceId } from '@subsocial/types/substrate/interfaces'

import { bnsToIds } from '@subsocial/utils'

const res = await substrateApi.query.spaceFollows.spacesFollowedByAccount('3osmnRNnrcScHsgkTJH1xyBF5kGjpbWHsGrqM31BJpy4vwn8') as Vec<SubstrateSpaceId>

const followedSpaceIds = bnsToIds(res) // array of Space ids

spaceFollowers

Get an array of account IDs that follow a space.

readyApi.query.spaceFollows.spaceFollowers(spaceId: SpaceId)

Example:

import { GenericAccountId as SubstrateAccountId } from '@polkadot/types'

import { SubstrateId } from '@subsocial/types';

const res = await substrateApi.query.spaceFollows.spaceFollowers('1') as Vec<SubstrateAccountId>

const followersBySpaceId = bnsToIds(res as unknown as SubstrateId[]) // array of Account ids

Find and load the list of followers and followings

accountFollowers

Get an array of account IDs that follow an account.

import { GenericAccountId as SubstrateAccountId } from '@polkadot/types'

import { SubstrateId } from '@subsocial/types'

const res = await substrateApi.query.profileFollows.accountFollowers('3osmnRNnrcScHsgkTJH1xyBF5kGjpbWHsGrqM31BJpy4vwn8') as Vec<SubstrateAccountId>

const accountFollowersIds = bnsToIds(res as unknown as SubstrateId[])

accountsFollowedByAccount

Get an array of account IDs that an account is following.

import { GenericAccountId as SubstrateAccountId } from '@polkadot/types'

import { SubstrateId } from '@subsocial/types'

const res = await substrateApi.query.profileFollows.accountsFollowedByAccount('3osmnRNnrcScHsgkTJH1xyBF5kGjpbWHsGrqM31BJpy4vwn8') as Vec<SubstrateAccountId>

const accountsFollowedByAccountIds = bnsToIds(res as unknown as SubstrateId[])
