SDK v1 to v2 migration guide

Most of the migration can be done quickly with AI: Using github copilot

Installation

yarn add @neynar/nodejs-sdk

npm install @neynar/nodejs-sdk

Client Initialization

import { NeynarAPIClient } from "@neynar/nodejs-sdk";

const client = new NeynarAPIClient("API_KEY", {
  baseOptions: {
    headers: {
      "x-neynar-experimental": true,
    },
  },
});

import { NeynarAPIClient, Configuration } from "@neynar/nodejs-sdk";

const config = new Configuration({
  apiKey: "API_KEY",
  baseOptions: {
    headers: {
      "x-neynar-experimental": true,
    },
  },
});

const client = new NeynarAPIClient(config);

Removed Methods and Changes in Method Names

All Neynar API v1-related methods have been removed from SDK v2. This version of the SDK will only support Neynar API v2.

Removed Methods

The following methods have been removed entirely from SDK v2:

Removed Method	Replacement
`fetchRecentUsers`	Use webhook or kafka
`fetchAllCastsLikedByUser`	`fetchUserReactions`
`lookupUserByFid`	`fetchBulkUsers`
`lookupCustodyAddressForUser`	`fetchBulkUsers`
`lookUpCastByHash`	`lookUpCastByHashOrWarpcastUrl`
`fetchAllCastsInThread`	`lookupCastConversation`
`fetchAllCastsCreatedByUser`	`fetchCastsForUser`
`fetchRecentCasts`	Use webhook or kafka
`fetchUserVerifications`	`fetchBulkUsers`
`lookupUserByVerification`	`fetchBulkUsersByEthOrSolAddress`
`fetchMentionAndReplyNotifications`	`fetchAllNotifications`
`fetchUserLikesAndRecasts`	`fetchUserReactions`

Checkout Affected v1 API Methods on how to replace it.

Renamed Methods

Several methods in SDK v2 have been renamed for consistency and clarity:

v1 Method Name	v2 Method Name
`lookUpCastByHashOrWarpcastUrl`	`lookupCastByHashOrWarpcastUrl`
`publishReactionToCast`	`publishReaction`
`deleteReactionFromCast`	`deleteReaction`
`fetchReactionsForCast`	`fetchCastReactions`
`fetchBulkUsersByEthereumAddress`	`fetchBulkUsersByEthOrSolAddress`

Methods Updated to v2 API

These methods retain the original method names but now use the v2 version of the neynar API:

v1 Method Name	v2 Method Name
`fetchUserFollowersV2`	`fetchUserFollowers`
`fetchUserFollowingV2`	`fetchUserFollowing`
`lookupUserByUsernameV2`	`lookupUserByUsername`

Enum Changes

Renamed enums

The following enums have been renamed in SDK v2 to align with the updated naming conventions:

v1 Enum Name	v2 Enum Name
`TimeWindow`	`FetchTrendingChannelsTimeWindowEnum`
`TrendingFeedTimeWindow`	`FetchTrendingFeedTimeWindowEnum`
`BulkCastsSortType`	`FetchBulkCastsSortTypeEnum`
`BulkUserAddressTypes`	`BulkUserAddressType`

Enum Key Changes

Certain enum keys have been modified in SDK v2. If you were using the following enums, be aware that their key formats may have changed:

NotificationType
ValidateFrameAggregateWindow
FetchTrendingChannelsTimeWindowEnum (formerly TimeWindow)
FetchTrendingFeedTimeWindowEnum (formerly TrendingFeedTimeWindow)
FetchBulkCastsSortTypeEnum (formerly BulkCastsSortType)
BulkUserAddressType (formerly BulkUserAddressTypes)

Import Path Changes

All the api-related enums and schemas are now centralized and exported from /build/api directory instead of /build/neynar-api/v2/*

import {CastParamType, NotificationTypeEnum, User, Cast, ...etc } from '@neynar/nodejs-sdk/build/api'

Imports for following isApiErrorResponse utility function and Webhook interfaces remains the same

import { isApiErrorResponse, WebhookFollowCreated, WebhookFollowDeleted, WebhookReactionCreated, WebhookReactionDeleted, WebhookCastCreated, WebhookUserCreated, WebhookUserUpdated } form '@neynar/nodejs-sdk'
